[PATCH 0/6] x86: reduce paravirtualized spinlock overhead
Paravirtualized spinlocks produce some overhead even if the kernel is
running on bare metal. The main reason are the more complex locking

instruction but so complex that it is no longer inlined.
This patch series addresses this issue by adding two more pvops
functions to reduce the size of the inlined spinlock functions. When
