1f49060adc cleanup powerpc/include/asm/ide.h
This patch removes code that became unused through IDE changes and the 
arch/ppc/ removal.

50d0b17645 powerpc: Use generic compat_sys_old_readdir
Use the generic compat_sys_old_readdir instead of the powerpc one which
is almost the same except for the almost complete lack of error
handling.

Note that we can't just use SYSCALL() in systbl.h because the native
syscall is named old_readdir, not sys_old_readdir.

81f14997e8 powerpc: Make CMO paging space pool ID and page size available
During platform setup, save off the primary/secondary paging space
pool IDs and the page size.  Added accessors in hvcall.h for these
variables.  This is needed for a subsequent fix.

22b8f9ee4a powerpc: Fix lockdep IRQ tracing bug
A small bogon sneaked into the ppc64 lockdep support.  A test is
branching slightly off causing a clobbered register value to
overwrite the irq state under some circumstances.

3fadc52b2c powerpc: Fix loss of vdso on fork on 32-bit
When we fork, init_new_context() improperly resets the vdso_base
of the new context to 0.  That means that the new process loses
access to the vdso for signal trampolines.

The initialization should be unnecessary anyway as the context
on a fresh mm should be 0 in the first place and binfmt_elf
will initialize that value for a newly loaded process.

163f6876f5 kexec jump: rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE
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.

bc033b63bb powerpc/mm: Fix attribute confusion with htab_bolt_mapping()
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.

b8b572e101 powerpc: Move include files to arch/powerpc/include/asm
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.
