Subject: powerpc/mm: Move page table index and and vaddr to pgtable.h
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aba480e1371358b419b2b680cc632f3210280b03;p=linux-beck.git

powerpc/mm: Move page table index and and vaddr to pgtable.h

Now that the page table size is a variable, we can move these to
generic pgtable.h.
