The main purpose of this series is to reduce the amount of #ifdefs in

This series also drops all CONFIG_PPC_64K_PAGES related code in book3e

Commit 67fda38f0d68 ("powerpc/mm: Move slb_addr_linit to
early_init_mmu") moved slb_addr_limit init out of setup_arch().
Commit 701101865f5d ("powerpc/mm: Reduce memory usage for mm_context_t
for radix") brought it back into setup_arch() by error.
This patch reverts that erroneous regress.
Fixes
This series is a split out of the v1 series "Reduce ifdef mess in hugetlbpage.c
and slice.c".
It is also rebased after the series from Aneesh to reduce context size for
Radix.

for wide compil
slice_mask_for_size() only uses mm->context, so hand directly a
pointer to the context. This will help moving the function in
subarch mmu.h in the next patch by avoiding having to include
the definition of struct mm_struct

Move slice_mask_for_size() into subarch mmu.h
At the same time, replace BUG() by VM_BUG_ON() as those BUG() are not
there to catch runtime errors but to catch errors during development
cycle only.
