Good idea.

[PATCH v2 0/9] x86: Concurrent TLB flushes
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 the remote CPUs to finish their work.
In addition, there are various small optimizations to avoid

[PATCH 00/10] x86/paravirt: several cleanups
This series removes some no longer needed stuff from paravirt
infrastructure and puts large quantities of paravirt ops under a new
config option PARAVIRT_XXL which is selected by XEN_PV only.
A pvops kernel without XEN_PV being configured is about 2.5% smaller
with this series applied.
