leds: Fix potential leds-gpio oops
Some time ago it turned out that our suspend code ordering broke some
NVidia-based systems that hung if _PTS was executed with one of the PCI
devices, specifically a USB controller, in a low power state.
Then, it was noticed that the suspend code ordering was not compliant
with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and
it was argued that the code had to be changed for that reason (ref.
http://bugzilla.kernel.org/show_bug.cgi?id=9528).
So we did, but evidently we did wrong, because it's now turning out that
some systems have been broken by this change. Refs:
http://bugzilla.kernel.org/show_bug.cgi?id=10340https://bugzilla.novell.com/show_bug.cgi?id=374217#c16
[ I said at that time that something like this might happend, but the
majority of people involved thought that it was improbable due to the
necessity to preserve the compliance of hardware with ACPI 1.0. ]
This actually is a quite serious regression from 2.6.24.
Moreover, the ACPI 1.0 ordering of suspend code introduced another issue
that I have only noticed recently. Namely, if the suspend of one of
devices fails, the already suspended devices will be resumed without
executing _WAK before, which leads to problems on some systems (for
example, in such situations thermal management is broken on my HP
nx6325). Consequently, it also breaks suspend debugging on the affected
systems.
Note also, that the requirement to execute _PTS before suspending
devices does not really make sense, because the device in question may
be put into a low power state at run time for a reason unrelated to a
system-wide suspend.
For the reasons outlined above, the change of the suspend ordering
should be reverted, which is done by the patch below.
[ Felix Möller: "I am the reporter from the original Novell Bug:
https://bugzilla.novell.com/show_bug.cgi?id=374217

Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from
parport IRQ handler), the latter enables interrupts without parport
subsystem IRQ handler expecting it.
The bug can be seen if you compile kernel with lock dependency checking
and use plip --- it produces a warning.
This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that
it doesn't enable interrupts when already disabled.

If "location" is > "addr_len" bits, the high bits of location would interfere
with the READ_CMD sent to the eeprom controller.
A patch was submitted to bug:
http://bugzilla.kernel.org/show_bug.cgi?id=4420
which simply truncated the "location", read whatever was in "location
modulo addr_len", and returned that value. That avoids confusing the
eeprom but seems like the wrong solution to me.
Correct would be to not read beyond "1 << addr_len" address of the eeprom.
I am submitting two changes to implement this:
1) tulip_read_eeprom will return zero (since we can't return -EINVAL)
if this is attempted (defensive programming).
2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't
iterate past addr_len bits and make sure the entire tp->eeprom[]
array is cleared.
I konw we don't strictly need both. I would prefer both in the tree
since it documents the issue and provides a second "defense" from
the bug from creeping back in.

The Coverity checker spotted that we leak the storage allocated to 'name' in
int driver_add_kobj(). The leak looks legit to me - this is the code :
int driver_add_kobj(struct device_driver *drv, struct kobject *kobj,
const char *fmt, ...)
{
va_list args;
char *name;
int ret;
va_start(args, fmt);
name = kvasprintf(GFP_KERNEL, fmt, args);
^^^^^^^^ This dynamically allocates space...
va_end(args);
if (!name)
return -ENOMEM;
return kobject_add(kobj, &drv->p->kobj, "%s", name);
^^^^^^^^ This neglects to free the space allocated
}
Inside kobject_add() a copy of 'name' will be made and used. As far as I can
see, Coverity is correct in flagging this as a leak, but I'd like some
configmation before the patch is applied.
This should fix it.

While looping for mtd[i]s, we should stop at the mtd[i] == NULL.
This patch also removes unnecessary "if (info)" checks:
suspend/resume/shutdown ops are executed only if probe() is succeeded, so info
is guaranteed to be !NULL.

Fix regression in dm-crypt introduced in commit
3a7f6c990a ("dm crypt: use async crypto").
If write requests need to be split into pieces, the code must not process them
in parallel because the crypto context cannot be shared. So there can be
parallel crypto operations on one part of the write, but only one write bio
can be processed at a time.
This is not optimal and the workqueue code needs to be optimized for parallel
processing, but for now it solves the problem without affecting the
performance of synchronous crypto operation (most of current dm-crypt users).

This reverts commit 3c0a654e39 and
fixes kernel bug #10245:
http://bugzilla.kernel.org/show_bug.cgi?id=10245
The HP Compaq nc6120 has the same PCI sub-device ID as the nx6110, and the
SMBus is used by ACPI for thermal management on the nc6120, so Linux should
not attach a native driver to it. This means that this quirk is unsafe and
has to be removed.
I also added a comment to help developers realize that adding new IDs to this
SMBus unhiding quirk table should be done only with great care, and in
particular only after checking that ACPI is not making use of the SMBus.

The following patch allows ixp4xx-beeper to be loaded by udev
automatically when compiled as a module with kernel versions 2.4.24 and
greater.
This patch is required because 43cc71eed1
("platform: prefix MODALIAS with "platform:"") changed the modalias
string to have the extra prefix.
LKG7102D7:~# udevinfo -a -p /sys/devices/platform/ixp4xx-beeper.4
looking at device '/devices/platform/ixp4xx-beeper.4':
KERNEL=="ixp4xx-beeper.4"
SUBSYSTEM=="platform"
DRIVER==""
ATTR{modalias}=="platform:ixp4xx-beeper"
udev therefore tries to modprobe platform:ixp4xx-beeper instead of
ixp4xx-beeper.
LKG7102D7:~# udevtest /sys/devices/platform/ixp4xx-beeper.4

main: run: '/sbin/modprobe --use-blacklist platform:ixp4xx-beeper'
With this patch, depmod adds an alias line (see below) to
modules.alias which allows modprobe to load the right module.

Because of a typo in iwch_accept_cr(), the cxgb3 connection handling
code programs the hardware IRD (incoming RDMA read queue depth) with
the value that is passed in for the ORD (outgoing RDMA read queue
depth). In particular this means that if an application passes in IRD
> 0 and ORD = 0 (which is a completely sane and valid thing to do for
an app that expects only incoming RDMA read requests), then the
hardware will end up programmed with IRD = 0 and the app will fail in
a mysterious way.
Fix this by using "ep->ird" instead of "ep->ord" in the intended place.
