Modified files:
sys/uvm : Tag: OPENBSD_5_9 uvm_mmap.c
Log message:
backport 1.137:
Since mappings established using __MAP_NOFAULT will be converted into anonymous
memory if the file backing the mapping is truncated, we should check resource
limits. This prevents callers from triggering a kernel panic and a potential
integer overflow in the amap code by forcing the allocation of too many slots.
Based on an analysis from Jesse Hertz and Tim Newsham.
