[PATCH 2/4] powerpc/stackprotector: work around stack-guard init from atomic

This is invoked from the secondary CPU in atomic context. On x86 we use tsc instead. On Power we XOR it against mftb() so lets use stack address as the initial value. Signed-off-by: Sebastian Andrzej Siewior --- arch/powerpc/include/asm/stackprotector.h | 4 1 file changed, 4 insertions(+)
