There are three different IO cards which an SGI IOC4 controller may find
itself on.  One of these variants does not bring out the IDE and serial

94a6735cd6 [PATCH] i4l: memory leak fix for sc_ioctl().
Fix leak of `rcvmsg' in sc_ioctl().

There are two returns in the switch in sc_ioctl (the SCIOCSTART case) that
may leak `rcvmsg'.  This patch fixes that by adding a kfree() call at the
beginning of that case.

Bug found by the coverity checker as #1098

Eric Sesterhenn send me a patch to fix the leak(s) by adding 2 kfree()
calls before the returns, I changed that into just a single call at the
beginning.

75e1fcc0b1 [PATCH] vfs: add lock owner argument to flush operation
Pass the POSIX lock owner ID to the flush operation.

This is useful for filesystems which don't want to store any locking state
in inode->i_flock but want to handle locking/unlocking POSIX locks
internally.  FUSE is one such filesystem but I think it possible that some
network filesystems would need this also.

Also add a flag to indicate that a POSIX locking request was generated by
close(), so filesystems using the above feature won't send an extra locking
request in this case.

454e2398be [PATCH] VFS: Permit filesystem to override root dentry on mount
Extend the get_sb() filesystem operation to take an extra argument that
permits the VFS to pass in the target vfsmount that defines the mountpoint.

The filesystem is then required to manually set the superblock and root dentry
pointers.  For most filesystems, this should be done with simple_set_mnt()
which will set the superblock pointer and then set the root dentry to the
superblock's s_root (as per the old default behaviour).

The get_sb() op now returns an integer as there's now no need to return the
superblock pointer.

This patch permits a superblock to be implicitly shared amongst several mount
points, such as can be done with NFS to avoid potential inode aliasing.  In
such a case, simple_set_mnt() would not be called, and instead the mnt_root
and mnt_sb would be set directly.

The patch also makes the following changes:

 (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount
     pointer argument and return an integer, so most filesystems have to change
     very little.

 (*) If one of the convenience function is not used, then get_sb() should
     normally call simple_set_mnt() to instantiate the vfsmount. This will
     always return 0, and so can be tail-called from get_sb().

 (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the
     dcache upon superblock destruction rather than shrink_dcache_anon().

     This is required because the superblock may now have multiple trees that
     aren't actually bound to s_root, but that still need to be cleaned up. The
     currently called functions assume that the whole tree is rooted at s_root,
     and that anonymous dentries are not the roots of trees which results in
     dentries being left unculled.

     However, with the way NFS superblock sharing are currently set to be
     implemented, these assumptions are violated: the root of the filesystem is
     simply a dummy dentry and inode (the real inode for '/' may well be
     inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries
     with child trees.

     [*] Anonymous until discovered from another tree.

 (*) The documentation has been adjusted, including the additional bit of
     changing ext2_* into foo_* in the documentation.

ca6bb5d7ab [NET]: Require CAP_NET_ADMIN to create tuntap devices.
The tuntap driver allows an admin to create persistent devices and
assign ownership of them to individual users. Unfortunately, relaxing
the permissions on the /dev/net/tun device node so that they can
actually use those devices will _also_ allow those users to create
arbitrary new devices of their own. This patch corrects that, and
adjusts the recommended permissions for the device node accordingly.

7967168cef [NET]: Merge TSO/UFO fields in sk_buff
Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not
going to scale if we add any more segmentation methods (e.g., DCCP).  So
let's merge them.

They were used to tell the protocol of a packet.  This function has been
subsumed by the new gso_type field.  This is essentially a set of netdev
feature bits (shifted by 16 bits) that are required to process a specific
skb.  As such it's easy to tell whether a given device can process a GSO
skb: you just have to and the gso_type field and the netdev's features
field.

I've made gso_type a conjunction.  The idea is that you have a base type
(e.g., SKB_GSO_TCPV4) that can be modified further to support new features.
For example, if we add a hardware TSO type that supports ECN, they would
declare NETIF_F_TSO | NETIF_F_TSO_ECN.  All TSO packets with CWR set would
have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO
packets would be SKB_GSO_TCPV4.  This means that only the CWR packets need
to be emulated in software.

5b057c6b1a [NET]: Avoid allocating skb in skb_pad
First of all it is unnecessary to allocate a new skb in skb_pad since
the existing one is not shared.  More importantly, our hard_start_xmit
interface does not allow a new skb to be allocated since that breaks
requeueing.

This patch uses pskb_expand_head to expand the existing skb and linearize
it if needed.  Actually, someone should sift through every instance of
skb_pad on a non-linear skb as they do not fit the reasons why this was
originally created.

Incidentally, this fixes a minor bug when the skb is cloned (tcpdump,
TCP, etc.).  As it is skb_pad will simply write over a cloned skb.  Because
of the position of the write it is unlikely to cause problems but still
it's best if we don't do it.

47005f255e [PATCH] libata: implement per-dev EH action mask eh_info->dev_action[]
Currently, the only per-dev EH action is REVALIDATE.  EH used to
exploit ehi->dev to do selective revalidation on a ATA bus.  However,
this is a bit hacky and makes it impossible to request selective
revalidation from outside of EH or add another per-dev EH action.

This patch adds per-dev EH action mask eh_info->dev_action[] and
update EH to use this field for REVALIDATE.  Note that per-dev actions
can still be specified at port-level and it has the same effect of
specifying the action for all devices on the port.

faster)

- Remove the skb_padto from orinoco. This got left in when the padding bad

4f1bcaf094 [PATCH] vgacon: make VGA_MAP_MEM take size, remove extra use
VGA_MAP_MEM translates to ioremap() on some architectures.  It makes sense
to do this to vga_vram_base, because we're going to access memory between
vga_vram_base and vga_vram_end.

But it doesn't really make sense to map starting at vga_vram_end, because
we aren't going to access memory starting there.  On ia64, which always has
to be different, ioremapping vga_vram_end gives you something completely
incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being
nonsense.

As a bonus, we often know the size up front, so we can use ioremap()
correctly, rather than giving it a zero size.

f522d23961 [PATCH] w1: Added default generic read/write operations.
Special file in each w1 slave device's directory called "rw" is created
each time new slave and no appropriate w1 family is registered.
"rw" file supports read and write operations, which allows to perform
almost any kind of operations. Each logical operation is a transaction
in nature, which can contain several (two or one) low-level operations.
Let's see how one can read EEPROM context:
1. one must write control buffer, i.e. buffer containing command byte
and two byte address. At this step bus is reset and appropriate device
is selected using either W1_SKIP_ROM or W1_MATCH_ROM command.
Then provided control buffer is being written to the wire.
2. reading. This will issue reading eeprom response.

It is possible that between 1. and 2. w1 master thread will reset bus for
searching and slave device will be even removed, but in this case 0xff will
be read, since no device was selected.

e1a8e913f9 [PATCH] lm70: New hardware monitoring driver
This driver implements support for the National Semiconductor LM70
temperature sensor.

The LM70 temperature sensor chip supports a single temperature sensor.
It communicates with a host processor (or microcontroller) via an
SPI/Microwire Bus interface.

Communication with the LM70 is simple: when the temperature is to be sensed,
the driver accesses the LM70 using SPI communication: 16 SCLK cycles
comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
complement digital temperature (sent via the SIO line), is available in the
driver for interpretation. This driver makes use of the kernel's in-core
SPI support.

The PCI quirk for users of fix_hstcfg was not developed because the
chipset lacks of subsystem ID registers and DMI is stated "To be
filled". Impact to existing systems is minimal because the problem
showed up on motherboards like 10 years back. On the other hand users

while they are being accessed.  They resume when a stop condition
exists on the i2c bus or when non-time related regs are accessed.
To make the best use of that facility and to make more efficient
use of the i2c bus, this patch replaces multiple i2c_smbus_xxx calls
with a single i2c_transfer call.

4ec223d02f [CPUFREQ] Fix ondemand vs suspend deadlock
Rootcaused the bug to a deadlock in cpufreq and ondemand. Due to non-existent
ordering between cpu_hotplug lock and dbs_mutex. Basically a race condition
between cpu_down() and do_dbs_timer().

cpu_down() flow:
* cpu_down() call for CPU 1
* Takes hot plug lock
* Calls pre down notifier
*     cpufreq notifier handler calls cpufreq_driver_target() which takes
      cpu_hotplug lock again. OK as cpu_hotplug lock is recursive in same
      process context
* CPU 1 goes down
* Calls post down notifier
*     cpufreq notifier handler calls ondemand event stop which takes dbs_mutex

So, cpu_hotplug lock is taken before dbs_mutex in this flow.

do_dbs_timer is triggerred by a periodic timer event.
It first takes dbs_mutex and then takes cpu_hotplug lock in
cpufreq_driver_target().
Note the reverse order here compared to above. So, if this timer event happens
at right moment during cpu_down, system will deadlok.

Attached patch fixes the issue for both ondemand and conservative.

d5ce1379be [PATCH] USB: negative index in drivers/usb/host/isp116x-hcd.c
From: Eric Sesterhenn <snakebyte@gmx.de>

This fixes coverity Bug #390.

With the following code

	ret = ep->branch = balance(isp116x, ep->period, ep->load);
	if (ret < 0)
		goto fail;

the problem is that ret and balance are of the type int, and ep->branch is u16.
so the int balance() returns gets reduced to u16 and then converted to an int again,
which removes the sign. Maybe the following little c program can explain it better:

ba47f66bd9 [PATCH] improved TT scheduling for EHCI
This updates the EHCI driver by adding an improved scheduler for the
transaction translators, found in USB 2.0 hubs and used for low and
full speed devices.

 - adds periodic_tt_usecs() and some helper functions, which does
   the same thing that "periodic_usecs" does, except on the other
   side of the TT, i.e.  it calculates the low/fullspeed bandwidth
   usage instead of highspeed.

 - adds a tt_available() function which is the new implementation
   of what tt_no_collision() does ... while tt_no_collision() ensures
   that each TT handles only 1 periodic transfer at a time (a very
   pessimistic approach) this version instead tracks bandwidth and
   allows each TT to handle as many transfers as will fit on each TT's
   downstream bus (closer to best-case).

The new scheduler is selected by a config option, marked as EXPERIMENTAL
so it can be tested (and more broadly reviewed) for a while until it
seems safe to remove the original scheduler.

e016683d59 [PATCH] USB: Remove 4088-byte limit on usbfs control URBs
This patch removes the artificial 4088-byte limit that usbfs
currently places on Control transfers. The USB spec does not
specify a strict limit on the size of an entire control transfer.
It does, however, state that the data stage "follows the same
protocol rules as bulk transfers." (USB 2, 8.5.3)

The level of support for large control transfers in real host
controllers varies, but it's important to support at least 4K
transfers. Windows enforces a maximum control transfer size
of 4K, so there exists some hardware that requires a full 4096
byte data stage. Without this patch, we fall short of that by
8 bytes on architectures with a 4K page size, and it becomes
impossible to support such hardware with a user-space driver.

Since any limit placed on control transfers by usbfs would be
arbitrary, this patch replaces the PAGE_SIZE limit with the same
arbitrary limit used by bulk transfers.

a82e49b8ae [PATCH] USB HID/HIDBP, INPUT DRIVERS: fix various usb/input/hid-input.c bugs that make Apple Mighty Mouse work poorly
Transposed lines of code in drivers/usb/input/hid-input.c causes the
capability bits for a new HID device to be set before quirks are applied
at configuration time.  When an HID event is then sent up to the input
layer, it may then be discarded as irrelevant because the wrong
capability bit is set.

Further, the quirks for the Apple Mighty Mouse are not quite right: the
horizontal scrolling needs its axis reversed, and the left and center
buttons are transposed.  Also, the mouse is labeled in the kernel with
its earlier name (I think) of Apple PowerMouse.

Steps to reproduce problem: Plug in an Apple Mighty Mouse.  Note that
horizontal scrolling doesn't work at all, and in fact doesn't generate
any input events on /dev/input/eventN.  Note also that pushing the
middle button performs the right button action, and vice versa.  Once
you have the horizontal scrolling working, note that it is backward WRT
both to vertical scrolling and to common sense.

This patch maybe should be broken up, as it does address two problems.
The transposed code in hidinput_configure_usage() probably creates bugs
beyond just the Mighty Mouse.  The rest of the patch renames POWERMOUSE
to MIGHTYMOUSE everywhere (which I *believe* is correct), fixes the
MIGHTYMOUSE quirk to swap the center and right mouse buttons, and adds a
new quirk HID_QUIRK_INVERT_HWHEEL also assigned to the MIGHTYMOUSE with
code in hidinput_hid_event() to implement it.

writers out there, we have a much smaller range of hardware to work with on
the shared device ID, so it should be possible to try some of the previous
probe options again: we just need to find another tester with a USBAT2-based HP
CD writer.

This patch hardcodes the flash detection until someone comes along with one of
these obscure CD drives. Note that these devices are extremely rare, so even if
we can't ever find a decent probe method, at least we will be supporting almost
all of the USBAT-based hardware out there.

141804d401 [PATCH] USB: shuttle_usbat: Fix handling of scatter-gather buffers
I've worked out what's going wrong.  The scsi layer is now much
more likely to pass down scatterlists instead of plain buffers.  So
you have to make sure that they're handled correctly.  In one of the
changes along the way, usbat_write_block and friends stopped obeying
the srb->use_sg flag.

Anyway, with the appended patch, and the one I'm putting in the next email, it
all seems to work for the HP cd4e.  Of course, someone's going to have
to test it with the flash drives as well....

This patch teaches the usbat_{read,write}_block functions to
obey the use_sg flag in the scsi-request.

a5117ba7da [PATCH] Driver model: add ISA bus
During the recent "isa drivers using platform devices" discussion it was
pointed out that (ALSA) ISA drivers ran into the problem of not having
the option to fail driver load (device registration rather) upon not
finding their hardware due to a probe() error not being passed up
through the driver model. In the course of that, I suggested a seperate
ISA bus might be best; Russell King agreed and suggested this bus could
use the .match() method for the actual device discovery.

The attached does this. For this old non (generically) discoverable ISA
hardware only the driver itself can do discovery so as a difference with
the platform_bus, this isa_bus also distributes match() up to the driver.

As another difference: these devices only exist in the driver model due
to the driver creating them because it might want to drive them, meaning
that all device creation has been made internal as well.

The usage model this provides is nice, and has been acked from the ALSA
side by Takashi Iwai and Jaroslav Kysela. The ALSA driver module_init's
now (for oldisa-only drivers) become:

static int __init alsa_card_foo_init(void)
{
	return isa_register_driver(&snd_foo_isa_driver, SNDRV_CARDS);
}

static void __exit alsa_card_foo_exit(void)
{
	isa_unregister_driver(&snd_foo_isa_driver);
}

Quite like the other bus models therefore. This removes a lot of
duplicated init code from the ALSA ISA drivers.

The passed in isa_driver struct is the regular driver struct embedding a
struct device_driver, the normal probe/remove/shutdown/suspend/resume
callbacks, and as indicated that .match callback.

The "SNDRV_CARDS" you see being passed in is a "unsigned int ndev"
parameter, indicating how many devices to create and call our methods with.

The platform_driver callbacks are called with a platform_device param;
the isa_driver callbacks are being called with a "struct device *dev,
unsigned int id" pair directly -- with the device creation completely
internal to the bus it's much cleaner to not leak isa_dev's by passing
them in at all. The id is the only thing we ever want other then the
struct device * anyways, and it makes for nicer code in the callbacks as
well.

With this additional .match() callback ISA drivers have all options. If
ALSA would want to keep the old non-load behaviour, it could stick all
of the old .probe in .match, which would only keep them registered after
everything was found to be present and accounted for. If it wanted the
behaviour of always loading as it inadvertently did for a bit after the
changeover to platform devices, it could just not provide a .match() and
do everything in .probe() as before.

If it, as Takashi Iwai already suggested earlier as a way of following
the model from saner buses more closely, wants to load when a later bind
could conceivably succeed, it could use .match() for the prerequisites
(such as checking the user wants the card enabled and that port/irq/dma
values have been passed in) and .probe() for everything else. This is
the nicest model.

To the code...

This exports only two functions; isa_{,un}register_driver().

isa_register_driver() register's the struct device_driver, and then
loops over the passed in ndev creating devices and registering them.
This causes the bus match method to be called for them, which is:

int isa_bus_match(struct device *dev, struct device_driver *driver)
{
          struct isa_driver *isa_driver = to_isa_driver(driver);

          if (dev->platform_data == isa_driver) {
                  if (!isa_driver->match ||
                          isa_driver->match(dev, to_isa_dev(dev)->id))
                          return 1;
                  dev->platform_data = NULL;
          }
          return 0;
}

The first thing this does is check if this device is in fact one of this
driver's devices by seeing if the device's platform_data pointer is set
to this driver. Platform devices compare strings, but we don't need to
do that with everything being internal, so isa_register_driver() abuses
dev->platform_data as a isa_driver pointer which we can then check here.
I believe platform_data is available for this, but if rather not, moving
the isa_driver pointer to the private struct isa_dev is ofcourse fine as
well.

Then, if the the driver did not provide a .match, it matches. If it did,
the driver match() method is called to determine a match.

If it did _not_ match, dev->platform_data is reset to indicate this to
isa_register_driver which can then unregister the device again.

If during all this, there's any error, or no devices matched at all
everything is backed out again and the error, or -ENODEV, is returned.

isa_unregister_driver() just unregisters the matched devices and the
driver itself.

More global points/questions...

- I'm introducing include/linux/isa.h. It was available but is ofcourse
a somewhat generic name. Moving more isa stuff over to it in time is
ofcourse fine, so can I have it please? :)

- I'm using device_initcall() and added the isa.o (dependent on
CONFIG_ISA) after the base driver model things in the Makefile. Will
this do, or I really need to stick it in drivers/base/init.c, inside
#ifdef CONFIG_ISA? It's working fine.

Lastly -- I also looked, a bit, into integrating with PnP. "Old ISA"
could be another pnp_protocol, but this does not seem to be a good
match, largely due to the same reason platform_devices weren't -- the
devices do not have a life of their own outside the driver, meaning the
pnp_protocol {get,set}_resources callbacks would need to callback into
driver -- which again means you first need to _have_ that driver. Even
if there's clean way around that, you only end up inventing fake but
valid-form PnP IDs and generally catering to the PnP layer without any
practical advantages over this very simple isa_bus. The thing I also
suggested earlier about the user echoing values into /sys to set up the
hardware from userspace first is... well, cute, but a horrible idea from
a user standpoint.

Comments ofcourse appreciated. Hope it's okay. As said, the usage model
is nice at least.

cf34a8e07f [PATCH] PCI: nVidia quirk to make AER PCI-E extended capability visible
The nVidia CK804 PCI-E chipset supports the AER extended capability
but sometimes fails to link it (with some BIOS or after a warm reboot).
It makes the AER cap invisible to pci_find_ext_capability().

The patch adds a quirk to set the missing bit that controls the
linking of the capability.
By the way, it removes the corresponding code in the myri10ge driver.

bdee9d98d2 [PATCH] PCI: Bus Parity Status sysfs interface
From: Doug Thompson <norsk5@yahoo.com>

This patch adds the 'broken_parity_status' sysfs attribute file to a PCI device.
Reading this attribute a userland program can determine if PCI device provides false
positives (value of 1) in its generation of PCI Parity status, or not (value of 0).
As PCI devices are found to be 'bad' in this regard, userland programs can also set
the appropriate value (root access only) of a faulty device. This per device
information will be used in the EDAC PCI Parity scanner code in a future patch once
this interface becomes available.

c0da3ba0a2 [PATCH] PCI: don't move ioapics below PCI bridge
A recent Stratus x86_64 platform uses a system ioapic that is a PCI device
located below a PCI bridge.  Other platforms like this may exist.

This patch fixes a problem wherein the kernel's PCI setup code moves
the ioapic to an address other than that assigned by the BIOS.  It simply
adds another exclusion (which already includes classless devices and host
bridges) to the function pbus_assign_resources_sorted so that it will not
move the ioapic.

If the ioapic is moved, the fixmap mapping to it is broken, so the OS should
leave it alone.

Brice said the pci_save_msi_state breaks his driver in his special usage
(not in suspend/resume), as pci_save_msi_state will disable msi mode. In
his usage, pci_save_state will be called at runtime, and later (after
the device operates for some time and has an error) pci_restore_state
will be called.
In another hand, suspend/resume needs disable msi mode, as device should
stop working completely. This patch try to workaround this issue.
Drivers are expected call pci_disable_device in suspend time after
pci_save_state.

We recently ran into a problem where the e1000 device failed to

device in the main kernel when it crashed. The e1000 driver
tried to enable MSI on the kexec kernel, but the code bailed
early when it found that MSI was already enabled in the hardware,
even though the software state was not properly set up in the
kexec'd kernel. This patch fixes the problem by moving the

is properly initialized.

bd8481e164 [PATCH] PCI Bus Parity Status-broken hardware attribute, EDAC foundation
Currently, the EDAC (error detection and correction) modules that are in
the kernel contain some features that need to be moved. After some good
feedback on the PCI Parity detection code and interface
(http://www.ussg.iu.edu/hypermail/linux/kernel/0603.1/0897.html) this
patch ADDs an new attribute to the pci_dev structure: Namely the
'broken_parity_status' bit.

When set this indicates that the respective hardware generates false
positives of Parity errors.

The EDAC "blacklist" solution was inferior and will be removed in a
future patch.

Also in this patch is a PCI quirk.c entry for an Infiniband PCI-X card
which generates false positive parity errors.

I am requesting comments on this AND on the possibility of a exposing
this 'broken_parity_status' bit to userland via the PCI device sysfs
directory for devices. This access would allow for enabling of this
feature on new devices and for old devices that have their drivers
updated. (SLES 9 SP3 did this on an ATI motherboard video device). There
is a need to update such a PCI attribute between kernel releases.

This patch just adds a storage place for the attribute and a quirk entry
for a known bad PCI device. PCI Parity reaper/harvestor operations are
in EDAC itself and will be refactored to use this PCI attribute instead
of its own mechanisms (which are currently disabled) in the future.

9f125d3048 [PATCH] PCI: Add a "enable" sysfs attribute to the pci devices to allow userspace (Xorg) to enable devices without doing foul direct access
This patch adds an "enable" sysfs attribute to each PCI device. When read it
shows the "enabled-ness" of the device, but you can write a "0" into it to
disable a device, and a "1" to enable it.

This later is needed for X and other cases where userspace wants to enable
the BARs on a device (typical example: to run the video bios on a secundary
head). Right now X does all this "by hand" via bitbanging, that's just evil.
This allows X to no longer do that but to just let the kernel do this.

PCI: Add pci_assign_resource_fixed -- allow fixed address assignments

On some embedded systems the PCI address for hotplug devices are not only
known a priori but are required to be at a given PCI address for other
master in the system to be able to access.

An example of such a system would be an FPGA which is setup from user space
after the system has booted.  The FPGA may be access by DSPs in the system
and those DSPs expect the FPGA at a fixed PCI address.

Added pci_assign_resource_fixed() as a way to allow assignment of the PCI
devices's BARs at fixed PCI addresses.

ea28502d5d [PATCH] PCI: fix to pci ignore pre-set 64-bit bars on 32-bit platforms
When we detect a 64-bit pre-set address in a BAR on a 32-bit platform,
we disable it and treat it as if it had been unset, thus allowing the
general address assignment code to assign a new address to it when the
device is enabled.  This can happen either if the firmware assigns
64-bit addresses; additionally, some cards have been found "in the
wild" which do not come out of reset with all the BAR registers set to
zero.

Unfortunately, the patch that implemented this tested the low part of
the address instead of the high part of the address.  This patch fixes
that.

17d6dc8ff0 [PATCH] PCI: Ignore pre-set 64-bit BARs on 32-bit platforms
[pci] Ignore pre-set 64-bit BARs on 32-bit platforms

Currently, Linux always rejects a device which has a pre-set 64-bit
address on a 32-bit platform.  On systems which do not do PCI
initialization in firmware, this causes some devices which don't
correctly power up with all BARs zero to fail.

This patch makes the kernel automatically zero out such an address
(thus treating it as if it had not been set at all, meaning it will
assign an address if necessary).

I have done this only for devices, not bridges.  It seems potentially
hazardous to do for bridges.

7bc3312bef [MTD] NAND: Fix breakage all over the place
Following problems are addressed:

- wrong status caused early break out of nand_wait()
- removed the bogus status check in nand_wait() which
  is a relict of the abandoned support for interrupted
  erase.
- status check moved to the correct place in read_oob
- oob support for syndrom based ecc with strange layouts
- use given offset in the AUTOOOB based oob operations

Partially based on a patch from Vitaly Vool <vwool@ru.mvista.com>
Thanks to Savin Zlobec <savin@epico.si> for tracking down the
status problem.

4faf4e0e7d [ARM] 3600/1: increase amba-pl010 UART_NR to 8
Patch from Lennert Buytenhek

The cirrus ep93xx has 3 pl010 UARTs, while amba-pl010.c only allows
for 2 by default.  A while ago, I think we agreed on changing the 2
to 8, but I don't see this in 2.6.17 yet.

d7a80dad2f [PATCH] libata: convert several bmdma-style controllers to new EH, take #3
Convert sata_sis, svw, uli and vsc drivers to new EH.  All the drivers
used to specify ATA_FLAG_SATA_RESET to tell libata to use SATA
hardreset instead of SRST.  This patch makes all the converted drivers
use the standard bmdma error handler which uses both SRST and SATA
hardreset.

All the controllers should be able to perform SRST but still needs
verification.  If some of the controllers can't do SRST, it will be
very easy to spot as it will show up during boot probing.

40ef1d8d48 [PATCH] sata_via: convert to new EH, take #3
Convert sata_via to new EH.  vt6420 used ATA_FLAG_SRST while vt6421
used ATA_FLAG_SATA_RESET.  This difference seems to be an accident
rather than intended.  This patch makes both flavors use
ata_bmdma_error_handler() which makes use of both SRST and SATA
hardreset.  This behavior change is intended and if it breaks
anything, it should be very easy to spot.

c5fa46e175 [libata] sata_nv: s/spin_lock_irqsave/spin_lock/ in irq handler
We don't need to use the heavier spin lock in the irq handler.

It's quite possible we can do this in nv_generic_interrupt() as well,
but I didn't take the time to pursue that train of thought.

ada364e884 [PATCH] sata_nv: better irq handlers
nf2/3 and ck804 have irq status register.  Implement better irq
handler for those flavors of nv.  This patch makes different flavors
of nv controllers use different irq handlers by using separate
port_info for each flavor.

This change also makes following EH and hotplug updates easier to
integrate.
