* ARC: Page Fault handlingVineet Gupta2013-02-15
This includes recent changes to make handler "retry" and/or "killable" The killable (early exit) logic is loosely based on how SH implements it return if SIGKILL + either of VM_FAULT_OOM or VM_FAULT_RETRY which is different from Hexagon implementation which would NOT early exit for SIGKILL + VM_FAULT_OOM + !VM_FAULT_RETRY credits: Non executable stack support from Simon Spooner Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
