Subject: powerpc/pseries: Move VPHN constants into vphn.h
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c040c7488b6a89c98dd0f6dd5f001101413779e2;p=linux.git

powerpc/pseries: Move VPHN constants into vphn.h

These don't have any particularly good reason to belong in lppaca.h,
move them into their own header.
