[PATCH] x86_64: Node local pda take 2 -- cpu_pda preparation
Helper patch to change cpu_pda users to use macros to access cpu_pda instead of the cpu_pda[] array. Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Shai Fultheim <shai@scalex86.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
