Souradeep Chakrabarti 7ece5993b7 Hyper-V: TLB flush enlightment using hypercall
Currently FreeBSD uses IPI based TLB flushing for remote
TLB flushing. Hyper-V allows hypercalls to flush local and
remote TLB. The use of Hyper-V hypercalls gives significant
performance improvement in TLB operations.

This patch set during test has shown near to 40 percent
TLB performance improvement.

Also this patch adds rep hypercall implementation as well.
