[PATCH] x86_64: Allocate PDAs in the local node
Patch uses a static PDA array early at boot and reallocates processor PDA with node local memory when kmalloc is ready, just before pda_init. The boot_cpu_pda is needed since the cpu_pda is used even before pda_init for that cpu is called (to set the static per-cpu areas offset table etc) 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>
