[PATCH v3 0/9] x86: Concurrent TLB flushes
[ Cover-letter is identical to v2, including benchmark results,
excluding the change log. ]
Currently, local and remote TLB flushes are not performed concurrently,
which introduces unnecessary overhead - each INVLPG can take 100s of
cycles. This patch-set allows TLB flushes to be run concurrently: first
request the remote CPUs to initiate the flush, then run it locally, and
finally wait for
