36247f5421 [NET_SCHED]: Fix qdisc_restart return value when dequeue is empty
My previous patch that changed the return value of qdisc_restart
incorrectly made the case where dequeue returns empty continue
processing packets.

This patch is based on diagnosis and fix by Patrick McHardy.

e971290133 meth driver renovation
The meth ethernet driver for the SGI IP32 aka O2 is so far still an old

causing issues with some udev based gadgetry in debian-stable.  Fixed by
converting the meth driver to a platform device.

d57c4a3892 [IA64] acpi_get_sysname() should be __init
Section mismatch: reference to .init.text:acpi_find_rsdp
 (between 'acpi_get_sysname' and 'acpi_request_vector')

acpi_get_sysname() needs to call the __init function acpi_find_rsdp, but it
doesn't have the __init attribute itself, hence the warning. Luckily it is
only called from machvec_init() which has __init attribute, so the fix
is to define acpi_get_sysname() as __init too.

92ea77275b Fix crash with irqpoll due to the IRQF_IRQPOLL flag testing
With irqpoll enabled, trying to test the IRQF_IRQPOLL flag in the
actions would cause a NULL pointer dereference if no action was
installed (for example, the driver might have been unloaded with
interrupts still pending).

So be a bit more careful about testing the flag by making sure to test
for that case.

(The actual _change_ is trivial, the patch is more than a one-liner
because I rewrote the testing to also be much more readable.

7fe7f8487a NFS: Avoid a deadlock situation on write
When processes are allowed to attempt to lock a non-contiguous range of nfs
write requests, it is possible for generic_writepages to 'wrap round' the
address space, and call writepage() on a request that is already locked by
the same process.

We avoid the deadlock by checking if the page index is contiguous with the
list of nfs write requests that is already held in our
nfs_pageio_descriptor prior to attempting to lock a new request.

e5f1b194a9 omap_uwire: SPI_CPHA mode bugfix
The omap_uwire controller driver handles SPI_CPHA incorrectly;
It should mean:

  CPHA=0 ... sample at leading edge of clock
  CPHA=1 ... sample at trailing edge of clock

This bug has been masked by inverse bugs in layered drivers;
and was uncovered by running some of them on non-OMAP hardware.
