[PATCH] powerpc: Eliminate "exceeds stub group size" linker warning

It turns out that the linker warnings on 64-bit powerpc about "section
blah exceeds stub group size" were being triggered by conditional
branches in head_64.S branching to global symbols, whether in
head_64.S or in other files.  This eliminates the warnings by making
some global symbols in head_64.S no longer global, and by rearranging
some branches.
