1) Core code stores the flow type already

We incorrectly returned -EINVAL when none of the devices in the array
had an integrity profile. This in turn prevented mdadm from starting

Commit 6f5317e730505d5cbc851c435a2dfe3d5a21d343 introduced a bug in the
handling of userspace object classes that is causing breakage for Xorg
when XSELinux is enabled. Fix the bug by changing map_class() to return
SECCLASS_NULL when the class cannot be mapped to a kernel object class.

Commit da48524eb206 ("Prevent rt_sigqueueinfo and rt_tgsigqueueinfo
from spoofing the signal code") made the check on si_code too strict.
There are several legitimate places where glibc wants to queue a
negative si_code different from SI_QUEUE:
- This was first noticed with glibc's aio implementation, which wants
to queue a signal with si_code SI_ASYNCIO; the current kernel
causes glibc's tst-aio4 test to fail because rt_sigqueueinfo()
fails with EPERM.
- Further examination of the glibc source shows that getaddrinfo_a()
wants to use SI_ASYNCNL (which the kernel does not even define).
The timer_create() fallback code wants to queue signals with SI_TIMER.
As suggested by Oleg Nesterov <oleg@redhat.com>, loosen the check to
forbid only the problematic SI_TKILL case.

The acpi video driver attempts to explicitly create a sysfs link between
the acpi device and the associated PCI device. However, we're now also
doing this from the backlight core, which means that we get a backtrace
caused by a duplicate file. Remove the code and leave it up to the
backlight core.

When a hole spans across page boundaries, the next write forces
a read of the block. This could end up reading existing garbage
data from the disk in ocfs2_map_page_blocks. This leads to
non-zero holes. In order to avoid this, mark the writes as new
when the holes span across page boundaries.

handle_prio_irq is almost identical with handle_fasteoi_irq. The
subtle differences are
1) The handler checks for IRQ_DISABLED after the device handler has
been called. In case it's set it masks the interrupt.
2) When the handler sees IRQ_DISABLED on entry it masks the interupt
in the same way as handle_fastoei_irq, but does not set the
IRQ_PENDING flag.
3) Instead of gracefully handling a recursive interrupt it crashes the
kernel.
#1 is just relevant when a device handler calls disable_irq_nosync()
and it does not matter whether we mask the interrupt right away or
not. We handle lazy masking for disable_irq anyway, so there is no
real reason to have this extra mask in place.
#2 will prevent the resend of a pending interrupt, which can result in
lost interrupts for edge type interrupts. For level type interrupts
the resend is a noop in the generic code. According to the
datasheet all interrupts are level type, so marking them as such
will result in the exact same behaviour as the private
handle_prio_irq implementation.
#3 is just stupid. Crashing the kernel instead of handling a problem
gracefully is just wrong. With the current semantics- all handlers
run with interrupts disabled - this is even more wrong.
Rename ack to eoi, remove the unused mask_ack, switch to
handle_fasteoi_irq and remove the private function.
