Modified files:
sys/kern kern_malloc.c
share/man/man9 Makefile
sys/conf NOTES files options
Added files:
share/man/man9 redzone.9
sys/vm redzone.c redzone.h
Log:
Add buffer corruption protection (RedZone) for kernel's malloc(9).
It detects both: buffer underflows and buffer overflows bugs at runtime
(on free(9) and realloc(9)) and prints backtraces from where memory was
allocated and from where it was freed.
Tested by: kris
