Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control
page is used for not only code on some platform. For example in kexec
jump, it is used for data and stack too.

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc:
powerpc: Remove include/linux/harrier_defs.h
powerpc: Do not ignore arch/powerpc/include
powerpc: Delete completed "ppc removal" task from feature removal file
powerpc/mm: Fix attribute confusion with htab_bolt_mapping()
powerpc/pci: Don't keep ISA memory hole resources in the tree
powerpc: Zero fill the return values of rtas argument buffer
powerpc/4xx: Update defconfig files for 2.6.27-rc1
powerpc/44x: Incorrect NOR offset in Warp DTS
powerpc/44x: Warp DTS changes for board updates
powerpc/4xx: Cleanup Warp for i2c driver changes.
powerpc/44x: Adjust warp-nand resource end address
The function htab_bolt_mapping() is used to create permanent
mappings in the MMU hash table, for example, in order to create
the linear mapping of vmemmap. It's also used by early boot
ioremap (before mem_init_done).
However, the way ioremap uses it is incorrect as it passes it the
protection flags in the "linux PTE" form while htab_bolt_mapping()
expects them in the hash table format. This is made more confusing by
the fact that some of those flags are actually in the same position in
both cases.
This fixes it all by making htab_bolt_mapping() take normal linux
protection flags instead, and use a little helper to convert them to
htab flags. Callers can now use the usual PAGE_* definitions safely.

Now that arch/ppc is gone and CONFIG_PPC_MERGE is always set, remove
the dead code associated with !CONFIG_PPC_MERGE from arch/powerpc
and include/asm-powerpc.

from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
