A bad page fault is when the HW signals an error such as a bad copy/paste, an AMO error, or some other type of error that will not be fixed by updating the PTE. Use a helper page_fault_is_bad() to check for bad page faults thus removing the per-processor family open-coding in __do_page_fault() and trigger a SIGBUS rather than a SIGSEGV which is more appropriate.
