Thomas Gleixner f6f1ae9128 x86/smpboot: Implement a bit spinlock to protect the realmode stack 
Parallel AP bringup requires that the APs can run fully parallel through
the early startup code including the real mode trampoline.

To prepare for this implement a bit-spinlock to serialize access to the
real mode stack so that parallel upcoming APs are not going to corrupt each
others stack while going through the real mode startup code.
