ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above

Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

Staging: android: binder: Fix memory leak on thread/process exit

If a thread or process exited while a reply, one-way transaction or
death notification was pending, the struct holding the pending work
was leaked.

Staging: android: binder: Allow using highmem for binder buffers

The default kernel mapping for the pages allocated for the binder
buffers is never used. Set the __GFP_HIGHMEM flag when allocating
these pages so we don't needlessly use low memory pages that may
be required elsewhere.

staging: android: Fix two checkpatch issues in binder.c

This fixes two instances of
"static const char * array should probably be static const char * const"

I have seen other commits doing this in other files, so I am
assuming it should be done here as well.

Please tell me if this is wrong :)

staging: android: Avoid using camelcase in binder.h

This changes the following:

1: BinderDriverReturnProtocol -> binder_driver_return_protocol
2: BinderDriverCommandProtocol -> binder_driver_return_protocol

These enums are not currently used, but still generate noise in checkpatch.

Well, did. They don't now :)

lib/lzo: Update LZO compression to current upstream version

This commit updates the kernel LZO code to the current upsteam version
which features a significant speed improvement - benchmarking the Calgary
and Silesia test corpora typically shows a doubled performance in
both compression and decompression on modern i386/x86_64/powerpc machines.

Enable UNALIGNED_ACCESS for the new LZO algorithm to use. LZO decrompression is used on QCACHE so we benefit a little from the new and improved LZO code.
