Modified files:
sys/i386/i386 machdep.c
Log:
Add a new loader tunable, hw.hasbrokenint12, to indicate that BIOS
has broken int 12H.
If hw.hasbrokenint12="1" in loader environment, kernel never use BIOS
INT 12 call to determine base memory size.
Otherwise, kernel use INT 12 in old behaviour.
This should fix kernel panic problem caused by 1.544 changes.
MFC after: 1 day
