NetBSD/src qVhfoWv — sys/arch/x86/include pmap.h, sys/arch/x86/x86 pmap.c

by ad on ⎇
   uvm_pagerealloc() can now block because of radixtree manipulation, so defer
   freeing PTPs until pmap_unmap_ptes(), where we still have the pmap locked
   but can finally tolerate context switches again.

   To be revisited soon: pmap_map_ptes() seems broken WRT other pmap load.
