SVN rev 212722 on 2010-09-16 03:46:17Z by nwhitehorn
Split the SLB mirror cache into two kinds of object, one for kernel maps
which are similar to the previous ones, and one for user maps, which
are arrays of pointers into the SLB tree. This changes makes user SLB
updates atomic, closing a window for memory corruption. While here,
rearrange the allocation functions to make context switches faster.
