History
Andreas Kling d21b8f9013 Kernel/SMP: Fix ProcessorMessage deallocation bug 
Due to a boolean mistake in smp_return_to_pool(), we didn't retry
pushing the message onto the freelist after a failed attempt.

This caused the message pool to eventually become completely empty
after enough contentious access attempts.

This patch also adds a pause hint to the CPU in the failed attempt
code path.
