[PATCH] x86_64: Fix race in TSC synchronization
Plug a race in TSC synchronization We need to do tsc_sync_wait() before the CPU is set online to prevent multiple CPUs from doing it in parallel - which won't work because TSC sync has global unprotected state. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
