[PATCH] m32r: fix ace_handler to pass full 32-bit address

Browse source

Don't mask the lower 12-bit of the page fault address.

In the current m32r kernel implementation, we use an access exception
to detect page faults.

This patch fixes ace_handler (access exception handler) for m32r.  In order to
check userspace address in do_page_fault, we have to pass full 32-bit address
to do_page_fault.
