Author: alc Date: Sat May 23 16:54:46 2015 New Revision: 283316 URL: https://svnweb.freebsd.org/changeset/base/283316 Log: Simplify the allocation of page table pages for mips64. Specifically, when allocation fails, it suffices to perform VM_WAIT. The direct map covers the entirely of physical memory, so unlike 32-bit mips any physical page can be used as a page table page.
