drive_cmd_intr() is used by both REQ_TYPE_ATA_CMD and REQ_TYPE_ATA_TASK
but commands using PIO-in protocol are valid only for REQ_TYPE_ATA_CMD
(&args[4] in case of REQ_TYPE_ATA_TASK points to a value for IDE_LCYL_REG
register instead of the data buffer). This fix allows REQ_TYPE_ATA_TASK
commands to use non-zero values for IDE_SECTOR_REG (args[3]).

Fix the memory leak that may occur when we attempt to reuse a cpu_slab
that was allocated while we reenabled interrupts in order to be able to
grow a slab cache.
The per cpu freelist may contain objects and in that situation we may
overwrite the per cpu freelist pointer loosing objects. This only
occurs if we find that the concurrently allocated slab fits our
allocation needs.
If we simply always deactivate the slab then the freelist will be
properly reintegrated and the memory leak will go away.

Fix this by adding some #ifdef's. Real fix would be to cleanup the

be quite a big patch. For the time being this is good enough.

smsgiucv is a driver that relies on iucv to work properly. If
iucv ans smsgiucv are compiled into the kernel and run on an
lpar the following scenario happens:
iucv is initialized early as a subsystem. It checks for z/VM and
returns with EPROTONOTSUPPORT. Later smsgiucv tries to run
driver_register with iucv_bus as bus. As this bus is not
initialized the driver core and list debugging issue several
warnings and oopses.
Solution is to let smsgiucv also check for z/VM and return
EPROTONOTSUPPORT as well.

The pvrusb2 driver is tearing down its sysfs related pieces in the
incorrect order. This leaves dangling pointers which causes the
kernel device core to oops. The problem has been present virtually
forever but became malignant with the changeover to the way of
handling /sys/class. Fix is just to make sure we don't tear down the
class structure until AFTER the driver instances are deregistered.

This em28xx-video.c uses functions from this header, but doesn't include it.
It depends on some v4l headers included two levels down including poll.h,
which includes mm.h.
These v4l headers might change, so it's best to include the headers needed
directly.
It also causes problems for the out of core build system's backward
compatibility with older kernels, which is the real reason I bothered to
create a patch for something that would otherwise be so minor that it would
hardly be worth the trouble.

You are right. The patch below (based on your cx88 patch, but I don't

Recording via mmap (arecord -M -f S16_LE -c 2 -r 32000 -D hw:1) didn't

The pvrusb2 driver's sysfs implementation had long since implemented a
dummy hotplug function because at the time the kernel would oops
without at least the empty function being present. Today - after
numerous class interface changes in the kernel - this pvrusb2 change
had been dutifully carried forward but an inspection of the kernel
sources shows that it is no longer needed. So remove the dummy
function and its reference. This also solves a recurring backwards
compatibility issue in the pvrusb2 driver as the class interface has
been getting thrashed in the kernel.
