* It is now possible to use percpu operations for pda access since the pda is in the percpu area. Drop the pda operations. Thus: read_pda --> x86_read_percpu write_pda --> x86_write_percpu add_pda (+1) --> x86_inc_percpu or_pda --> x86_or_percpu Based on linux-2.6.tip/master Signed-off-by: Christoph Lameter Signed-off-by: Mike Travis --- include/asm-x86/thread_info.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) --- linux-2.6.tip.orig/include/asm-x86/thread_info.h 2008-07-01 10:41:33.000000000 -0700 +++ linux-2.6.tip/include/asm-x86/thread_info.h 2008-07-01 10:49:15.172370813 -0700 @@ -200,7 +200,8 @@ static inline struct thread_info *curren static inline struct thread_info *current_thread_info(void) { struct thread_info *ti; - ti = (void *)(read_pda(kernelstack) + PDA_STACKOFFSET - THREAD_SIZE); + ti = (void *)(x86_read_percpu(pda.kernelstack) + + PDA_STACKOFFSET - THREAD_SIZE); return ti; } -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
