Arthur Heymans ac24a96579 arch/x86/spinlock.h: Support systems with >128 cores 
Each time the spinlock is acquired a byte is decreased and then the
sign of the byte is checked. If there are more than 128 cores the sign
check will overflow. An easy fix is to increase the word size of the
spinlock acquiring and releasing.

TEST: See that serialized SMM relocation is still serialized on
systems with >128 cores.
