From 365ba9179f84244d2ffa98e46ae3cddfeb2ef6ff Mon Sep 17 00:00:00 2001 From: Ravikiran G Thirumalai Date: Wed, 11 Jan 2006 22:45:42 +0100 Subject: [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 Signed-off-by: Shai Fultheim Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds --- include/asm-x86_64/pda.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'include/asm-x86_64/pda.h') diff --git a/include/asm-x86_64/pda.h b/include/asm-x86_64/pda.h index dc33d28a72dd..c7ab38a601af 100644 --- a/include/asm-x86_64/pda.h +++ b/include/asm-x86_64/pda.h @@ -27,9 +27,10 @@ struct x8664_pda { unsigned apic_timer_irqs; } ____cacheline_aligned_in_smp; -extern struct x8664_pda _cpu_pda[]; +extern struct x8664_pda *_cpu_pda[]; +extern struct x8664_pda boot_cpu_pda[]; -#define cpu_pda(i) (&_cpu_pda[i]) +#define cpu_pda(i) (_cpu_pda[i]) /* * There is no fast way to get the base address of the PDA, all the accesses -- cgit v1.2.1
