powerpc: Merge atomic.h and memory.h into powerpc
Merged atomic.h into include/powerpc. Moved asm-style HMT_ defines from
memory.h into ppc_asm.h, where there were already HMT_defines; moved c-style
HMT_ defines to processor.h. Renamed memory.h to synch.h to better reflect
its contents.

The spinlock_types.h merge renamed the structure for raw_spinlock_t to
match ppc64. In doing so some of the spinlock macros/functions needed to
be updated to match. Apparently, this seems to only be caught when
building power3.

Merged hw_irq.h between ppc32 & ppc64. Added support to use the Book-E
wrtee[i] instructions that allow modifying MSR[EE] atomically.
Additionally, added get_irq_desc() macros to ppc32 to allow mask_irq(),
unmask_irq(), and ack_irq() to be common between ppc32 & ppc64.
Note: because 64-bit Book-E implementations only have a 32-bit MSR the
macro's for Book-E need to come before the PPC64 macro's to ensure the
right thing happends for 64-bit Book-E processors.

The merging of auxvec.h into asm-powerpc introduced the AT_SYSINFO_EHDR
into the ppc32 build that is used for VDSO. However, we dont have VDSO
support in the ppc32 tree at this time. Introducing this define causes
a number of other things to get built with the assumption of VDSO, thus
causing the compile errors for ppc32.
Until we have VDSO on ppc32 we will leave AT_SYSINFO_EHDR a ppc64 only
define.

ppc/ppc64: Merge elf.h into include/asm-powerpc
Merge elf.h into a single include file for 32 and 64-bit ppc platforms. This
patch has been tested on 32-bit and built on 64-bit platforms.

ppc32/ppc64: Merge bug.h into include/asm-powerpc
This patch merges bug.h into include/asm-powerpc. Changed the data
structure for bug_entry such that line is always an int on both 32 and
64-bit platforms; removed casts to int from the 64-bit trap code to
reflect this.

This is a revised patch to merge asm-ppc*/hardirq.h.
It removes some unnecessary #includes, but then requires
the addition of #include <asm/irq.h> in PPC32's hw_irq.h
much like ppc64 already does. Furthermore, several
unnecessary #includes were removed from some ppc32 boards
in order to break resulting bad #include cycles.
Builds pSeries_defconfig and all ppc32 platforms except
the already b0rken bseip.

On ppc64 timer_interrupt() returned a value that was never used. Changed
the ppc64 version of timer_interrupt() to no longer return a value so
that the signatures between ppc32 & ppc64 match. This will simplify
future merging of arch/powerpc.

This patch slightly change the TLB flush batch mecanism so that we
store the full vaddr (including vsid) when adding an entry to the
batch so that the flush part doesn't have to get to the context.
This cleans it a bit, and paves the way to future updates like
dynamic vsids.
