Subject: force the pool of pmapvp onto PAGE_SIZE allocations by specifying a
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=57f11335980ebade044bd70910733d76d9a90a8d;p=openbsd

force the pool of pmapvp onto PAGE_SIZE allocations by specifying a
pool allocator. pmapvp is 1024 bytes, and the size * 8 change in pools
without an allocator being specified tries to place it on large pages.
you need pmap to use large pages, and pmap isnt set up yet.

fixed a very early fault on macppc.
