src/sys/rump/librump/rumpkern: vm.c
Log Message:
Improve page allocator performance by using pool_cache for the
structure itself and allocating the backing page directly from the
hypervisor.
* initial write to a large tmpfs file is almost 2x faster
* truncating the file to 0 length after write is over 50% faster
* rewrite of the file is just slightly faster (indicating that
kmem does a good job with caching, as expected)
