mips (and sparc32):
In file included from arch/mips/include/asm/tlb.h:21,
from mm/pgtable-generic.c:9:
include/asm-generic/tlb.h: In function `tlb_flush_mmu':
include/asm-generic/tlb.h:76: error: implicit declaration of function `release_pages'
include/asm-generic/tlb.h: In function `tlb_remove_page':
include/asm-generic/tlb.h:105: error: implicit declaration of function `page_cache_release'
free_pages_and_swap_cache() and free_page_and_swap_cache() are macros
which call release_pages() and page_cache_release(). The obvious fix is
to include pagemap.h in swap.h, where those macros are defined. But that
breaks sparc for weird reasons.
So fix it within mm/pgtable-generic.c instead.

pmdp_get_and_clear/pmdp_clear_flush/pmdp_splitting_flush were trapped as
BUG() and they were defined only to diminish the risk of build issues on
not-x86 archs and to be consistent with the generic pte methods previously
defined in include/asm-generic/pgtable.h.
But they are causing more trouble than they were supposed to solve, so
it's simpler not to define them when THP is off.
This is also correcting the export of pmdp_splitting_flush which is
currently unused (x86 isn't using the generic implementation in
mm/pgtable-generic.c and no other arch needs that [yet]).

Some are needed to build but not actually used on archs not supporting
transparent hugepages. Others like pmdp_clear_flush are used by x86 too.
