cf9f6e21c1 3c509: Add missing EISA IDs
Several EISA device IDs for 3c509 family network cards are missing from 
the driver, making the cards unusable in their EISA mode.  Here's a fix to 
add them based on the EISA configuration files distributed by 3Com and our

c339dfdd65 ide_pci_generic: add quirk for Netcell ATA RAID
We need to explicitly mark words 85-87 as valid ones since
firmware doesn't do it.

This should fix support for LBA48 and FLUSH CACHE [EXT] command
which stopped working after we applied more strict checking of
identify words in:

	commit 942dcd85bf
	("ide: idedisk_supports_lba48() -> ata_id_lba48_enabled()")

and

	commit 4b58f17d7c

Commit 4973b22a ("ACPI processor: reset the throttling state once it's

34d531e640 ACPI: sanity check _PSS frequency to prevent cpufreq crash
When BIOS SETUP is changed to disable EIST, some BIOS
hand the OS an un-initialized _PSS:

        Name (_PSS, Package (0x06)
        {
            Package (0x06)
            {
                0x80000000,	// frequency [MHz]
                0x80000000,	// power [mW]
                0x80000000,	// latency [us]
                0x80000000,	// BM latency [us]
                0x80000000,	// control
                0x80000000	// status
            },
	    ...

These are outrageous values for frequency,
power and latency, raising the question where to draw
the line between legal and illegal.  We tend to survive
garbage in the power and latency fields, but we can BUG_ON
when garbage is in the frequency field.

Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz.
So disregard a _PSS with a frequency so large
that it can't be represented by cpufreq.

b8e7e40abe 8250: Fix oops from setserial
If you setserial a port which has never been initialised we change the type
but don't update the I/O method pointers. The same problem is true if you
change the io type of a port - but nobody ever does that so nobody noticed!

Remember the old type and when attaching if the type has changed reload the
port accessor pointers. We can't do it blindly as some 8250 drivers load custom
accessors and we must not stomp those.

   between the successive READID flash commands.
 - compile error when CONFIG_PM is enabled
 - pass on the error code from clk_get()
 - return -ENOMEM in case of failed ioremap()
 - pass on the return value of platform_driver_probe() directly
 - remove excessive printk
 - let command line partition table parsing with mxc_nand name.
   The cmd_line parsing is done via <mtd-id> name that differs
   from mxc_nand by default and looks like "NAND 256MiB 1,8V 8-bit"

10b6d95612 cxgb3: fix dma mapping regression
Commit 5e68b772e6
  cxgb3: map entire Rx page, feed map+offset to Rx ring.

introduced a regression on platforms defining DECLARE_PCI_UNMAP_ADDR()
and related macros as no-ops.

Rx descriptors are fed with the a page buffer bus address + page chunk offset.
The page buffer bus address is set and retrieved through
pci_unamp_addr_set(), pci_unmap_addr().
These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set).
The HW ends up with a bogus bus address.

This patch saves the page buffer bus address for all plaftorms.

2f102607ac i7300_idle: allow testing on i5000-series hardware w/o re-compile
Testing the i7300_idle driver on i5000-series hardware required
an edit to i7300_idle.h to "#define SUPPORT_I5000 1" and a re-build
of both i7300_idle and ioat_dma.

Replace that build-time scheme with a load-time module parameter:
"7300_idle.forceload=1" to make it easier to test the driver
on hardware that while not officially validated, works fine
and is much more commonly available.

By default (no modparam) the driver will continue to load
only on the i7300.

Note that ioat_dma runs a copy of i7300_idle's probe routine
to know to reserve an IOAT channel for i7300_idle.
This change makes ioat_dma do that always on the i5000,
just like it does on the i7300.

29868b281f Revert "USB: Correct Makefile to make isp1760 buildable"
This reverts commit 26e1287594.

A larger patch (f7e7aa585) a few days after this one added the same line
to the Makefile, but in a different place.  While it'd be more correct to
revert that one, it's easier to revert this one because this is a
one-liner.

0a3c8549ea usb-serial: fix crash when sub-driver updates firmware
This patch (as1244) fixes a crash in usb-serial that occurs when a
sub-driver returns a positive value from its attach method, indicating
that new firmware was loaded and the device will disconnect and
reconnect.  The usb-serial core then skips the step of registering the
port devices; when the disconnect occurs, the attempt to unregister
the ports fails dramatically.

This problem shows up with Keyspan devices and it might affect others
as well.

When the attach method returns a positive value, the patch sets
num_ports to 0.  This tells usb_serial_disconnect() not to try
unregistering any of the ports; instead they are cleaned up by
destroy_serial().

0afb20e00b USB: isp1760: urb_dequeue doesn't always find the urbs
The option driver (and presumably others) allocates several URBs when it
opens and tries to free them when it closes. The isp1760_urb_dequeue
function gets called, but the packet being dequeued is not necessarily at
the
front of one of the 32 queues. If not, the isp1760_urb_done function doesn't
get called for the URB and the process trying to free it hangs forever on a
wait_queue. This patch does two things. If the URB being dequeued has others
queued behind it, it re-queues them. And it searches the queues looking for
the URB being dequeued rather than just looking at the one at the front of
the queue.

a3ce6ea46c Input: libps2 - better handle bad scheduler decisions
Sometimes devices send us their responses in time but due to
unfortunate scheduling decisions the receiving thread does not
get scheduled till much later and we erroneously decide that
device timed out. Work around this problem by checking whether we
received the data we needed instead of checking timeout
condition.

dacd2549ca PCI/ACPI: fix wrong ref count handling in acpi_pci_bind()
The 'dev' field of struct acpi_pci_data is having a pointer to struct
pci_dev without incrementing the reference counter. Because of this, I
got the following kernel oops when I was doing some pci hotplug
operations. This patch fixes this bug by replacing wrong hand-made
pci_find_slot() with pci_get_slot() in acpi_pci_bind().

07f4f3e8a2 i915: Set object to gtt domain when faulting it back in
When a GEM object is evicted from the GTT we set it to the CPU domain,
as it might get swapped in and out or ever mmapped regularly.  If the
object is mmapped through the GTT it can still get evicted in this way
by other objects requiring GTT space.  When the GTT mapping is touched
again we fault it back into the GTT, but fail to set it back to the
GTT domain.  This means we fail to flush any cached CPU writes to the
pages backing the object which will then happen "eventually", typically
after we write to the page through the uncached GTT mapping.

[anholt: Note that userland does do a set_domain(GTT, GTT) when starting
to access the GTT mapping.  That covers getting the existing mapping of the
object synchronized if it's bound to the GTT.  But set_domain(GTT, GTT)
doesn't do anything if the object is currently unbound.  This fix covers the
transition to being bound for GTT mapping.]

Fixes glyph and other pixmap corruption during swapping.  fd.o bug #21790
