dillon 2001/10/30 19:06:33 PST Modified files: sys/vm vm_map.h vm_map.c sys/i386/i386 pmap.c Log: Don't let pmap_object_init_pt() exhaust all available free pages (allocating pv entries w/ zalloci) when called in a loop due to an madvise(). It is possible to completely exhaust the free page list and cause a system panic when an expected allocation fails.
