Modified Files:
src/sys/arch/x86/x86: pmap.c
Log Message:
- pmap_enter(): under low memory conditions, if PTP allocation succeeded and
then PV entry allocation failed, PTP pages were being freed without their
struct pmap_page being reset back to the non-PTP setup, which then caused
havoc with pmap_page_removed(). Fix it.
- pmap_enter_pv(): don't do the PV check if memory allocation failed.
