Log message:
Implement per-CPU caching for the page table page (vp) pool and the PTE
descriptor (pted) pool in the [riscv64] pmap implementation. This
significantly reduces the side-effects of lock contention on the kernel
map lock that is (incorrectly) translated into excessive page daemon
wakeups. This is not a perfect solution but it does lead to significant
speedups [on the Hifive Unmatched]
Improvement and commit message adapted from kettenis' rev 1.110 commit
to arm64/pmap.c. ok phessler@ kettenis@
