Benjamin Herrenschmidt 5e5419734c add mm argument to pte/pmd/pud/pgd_free
(with Martin Schwidefsky <schwidefsky@de.ibm.com>)

The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
first argument.  The free functions do not get the mm_struct argument.  This
is 1) asymmetrical and 2) to do mm related page table allocations the mm
argument is needed on the free function as well.

David Gibson d1953c8888 [POWERPC] Remove use of 4level-fixup.h for ppc32
For 32-bit systems, powerpc still relies on the 4level-fixup.h hack,
to pretend that the generic pagetable handling stuff is 3-levels
rather than 4.  This patch removes this, instead using the newer
pgtable-nopmd.h to handle the elision of both the pud and pmd
pagetable levels (ppc32 pagetables are actually 2 levels).

This removes a little extraneous code, and makes it more easily
compared to the 64-bit pagetable code.

David Gibson f88df14b1f [POWERPC] Remove arch/powerpc's dependence on asm-ppc/pg{alloc,table}.h
Currently, all 32-bit powerpc platforms use asm-ppc/pgtable.h and
asm-ppc/pgalloc.h, even when otherwise compiled with ARCH=powerpc.
Those asm-ppc files are a fairly nasty tangle of #ifdefs including a
bunch of things which shouldn't be necessary any more in arch/powerpc.

Cleaning up that mess is going to take a while, but this patch is a
first step.  It separates the asm-powerpc/pg{alloc,table}.h into 64
bit and 32 bit versions in asm-powerpc, which the basic .h files in
asm-powerpc select based on config.  We make a few tiny tweaks to the
innards of the files along the way, making the outermost ifdefs
(double-inclusion protection and __KERNEL__) a little cleaner, and
#including asm-generic/pgtable.h from the top-level
asm-powerpc/pgtable.h (since both the old 32-bit and 64-bit versions
ended with such an #include).
