Log:
SVN rev 212715 on 2010-09-16 00:22:25Z by nwhitehorn
Replace the SLB backing store splay tree used on 64-bit PowerPC AIM
hardware with a lockless sparse tree design. This marginally improves
the performance of PMAP and allows copyin()/copyout() to run without
acquiring locks when used on wired mappings.
