8c65b4a604 [PATCH] fix remaining missing includes
Fix more include file problems that surfaced since I submitted the previous
fix-missing-includes.patch.  This should now allow not to include sched.h
from module.h, which is done by a followup patch.

30415f6a63 powerpc: Fix random memory corruption in merged elf.h
The merged verison of ELF_CORE_COPY_REGS is basically the PPC64 version, with
a memset that came from PPC and a few types abstracted out into #defines. But
it's not _quite_ right.

The first problem is we calculate the number of registers with:
        nregs = sizeof(struct pt_regs) / sizeof(ELF_GREG_TYPE)

For a 32-bit process on a 64-bit kernel that's bogus because the registers are
64 bits, but ELF_GREG_TYPE is u32, so nregs == 88 which is wrong.

The other problem is the memset, which assumes a struct pt_regs is smaller
than a struct elf_regs. For a 32-bit process on a 64-bit kernel that's false.

The fix is to calculate the number of regs using sizeof(unsigned long), which
should always be right, and just memset the whole damn thing _before_ copying
the registers in.

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.

a99eb2ef45 [PATCH] powerpc: Merge elf.h
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.
