[PATCH] i386: Replace broken serialize_cpu in microcode driver with correct sync_core
Passing random input values in eax to cpuid is not a good idea because the CPU will GPF for unknown ones. Use the correct x86-64 version that exists for a longer time too. This also adds a memory barrier to prevent the optimizer from reordering. Cc: tigran@veritas.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
