Hi,

Is it possible to figure out the fault type(READ or WRITE fault)
from inside the page fault handler in user space? I can get the
faulting address fine but I have trouble figuring out the fault
type. I looked at the i386/i386/machdep.c but couldn't find
anything about the access/fault type.

Any help would be appreciated.

Thanks,
Murali
