Convert the backlight and LCD classes from struct class_device
to struct device since class_device is scheduled for removal.
One nasty API break is the backlight power attribute has had to be
renamed to bl_power and the LCD power attribute has had to be renamed
to lcd_power since the original names clash with the core. I can't see
a way around this.

* 'audit.b39' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/audit-current:
[PATCH] get rid of AVC_PATH postponed treatment
[PATCH] allow audit filtering on bit & operations
[PATCH] audit: fix broken class-based syscall audit

Selinux folks had been complaining about the lack of AVC_PATH
records when audit is disabled. I must admit my stupidity - I assumed
that avc_audit() really couldn't use audit_log_d_path() because of
deadlocks (== could be called with dcache_lock or vfsmount_lock held).
Shouldn't have made that assumption - it never gets called that way.
It _is_ called under spinlocks, but not those.
Since audit_log_d_path() uses ab->gfp_mask for allocations,
kmalloc() in there is not a problem. IOW, the simple fix is sufficient:
let's rip AUDIT_AVC_PATH out and simply generate pathname as part of main
record. It's trivial to do.

The sanity check in audit_match_class() is wrong. We are able to audit
2048 syscalls but in audit_match_class() we were accidentally using
sizeof(_u32) instead of number of bits in _u32 when deciding how many
syscalls were valid. On ia64 in particular we were hitting syscall
numbers over the (wrong) limit of 256. Fixing the audit_match_class
check takes care of the problem.

Some HW platforms, such as the new cell blades, requires some MPIC sources
to be left alone by the operating system. This implements support for
a "protected-sources" property in the mpic controller node containing a list
of source numbers to be protected against operating system interference.
For those interested in the gory details, the MPIC on the southbridge of
those blades has some of the processor outputs routed to the cell, and
at least one routed as a GPIO to the service processor. It will be used
in the GA product for routing some of the southbridge error interrupts
to the service processor which implements some of the RAS stuff, such
as checkstopping when fatal errors occurs before they can propagate.

Classic 32-bit PowerPC CPUs, and the early 64-bit PowerPC CPUs, don't
provide a way to prevent execution from readable pages, that is, the
MMU doesn't distinguish between data reads and instruction reads,
although a different exception is taken for faults in data accesses
and instruction accesses.
Commit 9ba4ace39fdfe22268daca9f28c5df384ae462cf, in the course of
fixing another bug, added a check that meant that a page fault due
to an instruction access would fail if the vma did not have the
VM_EXEC flag set. This gives an inconsistent enforcement on these
CPUs of the no-execute status of the vma (since reading from the page
is sufficient to allow subsequent execution from it), and causes old
versions of ppc32 glibc (2.2 and earlier) to fail, since they rely
on executing the word before the GOT but don't have it marked
executable.
This fixes the problem by allowing execution from readable (or writable)
areas on CPUs which do not provide separate control over data and
instruction reads.

Move firmware feature initialisation from pSeries_init_early to the
earlier pSeries_probe_hypertas so they are initialised before firmware
feature fixups are applied.
Currently firmware feature sections are only used for iSeries which
initialises the these features much earlier. This is a bug in waiting
on pSeries.
Also adds some whitespace fixups.

The file name is the signature, such as DSDT,
and the contents are the binary table image.
Some tables, such as the SSDT, can have multiple instances.
If just one, the file is SSDT, but if 3 instances,
for example, it will be SSDT1, SSDT2, SSDT3
All static tables (besides teh RSDP and RSDT themselves
are exported. Dynamic tables, such as SSDT op-regions that
are not declared in the RSDT, will be added in a subsequent patch.
