Modified files:
sys/sparc64/include tlb.h
sys/sparc64/sparc64 pmap.c
Log:
Fix crashes that would happen when more than one 4MB page was used to
hold the kernel text, data and loader metadata by not using a fixed slot
to store the TSB page(s) into. Enter fake 8k page entries into the kernel
TSB that cover the 4M kernel page(s), sot that pmap_kenter() will work
without having to treat these pages as a special case.
Problem reported by: mjacob, obrien
Problem spotted and 4M page handling proposed by: jake
