40ef8cbc6d powerpc: Get 64-bit configs to compile with ARCH=powerpc
This is a bunch of mostly small fixes that are needed to get
ARCH=powerpc to compile for 64-bit.  This adds setup_64.c from
arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c.

9f04b9e327 powerpc: Merged processor.h.
This adds register definitions from the ppc64 processor.h to reg.h,
and makes a single merged processor.h.  I moved __is_processor from
the ppc64 system.h to the merged reg.h along with the PVR register
constants.

9b6b563c0d powerpc: Merge in the ppc64 version of the prom code.
This brings in the ppc64 version of prom_init.c, prom.c and btext.c
and makes them work for ppc32.  This also brings in the new calling
convention, where the first entry to the kernel (with r5 != 0) goes
to the prom_init code, which then restarts from the beginning (with
r5 == 0) after it has done its stuff.

For now this also brings in the ppc32 version of setup.c.  It also
merges lmb.h.

400d221274 [PATCH] ppc32: make cur_cpu_spec a single pointer instead of an array
Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs.
Additionally, made call_setup_cpu check to see if the cpu_setup pointer
is NULL or not before calling the function.  This lets remove the dummy
cpu_setup calls that just return.

a559c91d77 [PATCH] powerpc: merge byteorder.h
powerpc: Merge byteorder.h

Essentially adopts the 64-bit version of this file.  The 32-bit version had
been using unsigned ints for arguments/return values that were actually
only 16 bits - the new file uses __u16 for these items as in the 64-bit
version of the header.  The order of some of the asm constraints
in the 64-bit version was slightly different than the 32-bit version,
but they produce identical code.

14cf11af6c powerpc: Merge enough to start building in arch/powerpc.
This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.

powerpc: Merge semaphore.h

Adopted the ppc64 version of semaphore.h.  The 32-bit version used
smp_wmb(), but recent updates to atomic.h mean this is no longer required.
The 64-bit version made use of unlikely(), which has been retained in the
combined version.

This patch requires the recent atomic.h patch.

b671ad2bef [PATCH] powerpc: merged hw_irq.h
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.

fa2ac7a25f [PATCH] powerpc: Fix compiling of ppc32
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.

unnecessary #includes were removed from some ppc32 boards
in order to break resulting bad #include cycles.

Builds pSeries_defconfig and all ppc32 platforms except

a94d308513 [PATCH] ppc64: Add definitions for new PTRACE calls
- Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is
  as follows:

/*
 * Get or set a debug register. The first 16 are DABR registers and the
 * second 16 are IABR registers.
 */
#define PTRACE_GET_DEBUGREG    25
#define PTRACE_SET_DEBUGREG    26

  DABR == data breakpoint and IABR = instruction breakpoint in IBM
  speak. We could split out the IABR into 2 more ptrace calls but I
  figured there was no need and 16 DABR registers should be more
  than enough (POWER4/POWER5 have one).

- Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt
  find any standards on either of these so I copied what ia64 is
  doing. Again this might be better placed in
  include/asm-generic/siginfo.h
