x86/mce: Check for faults tagged in EXTABLE_CLASS_FAULT exception table entries
Extend the severity checking code to add a new context IN_KERN_RECOV which is used to indicate that the machine check was triggered by code in the kernel tagged with _ASM_EXTABLE_FAULT() so that the ex_handler_fault() handler will provide the fixup code with the trap number. Major re-work to the tail code in do_machine_check() to make all this readable/maintainable. One functional change is that tolerant=3 no longer stops recovery actions. Revert to only skipping sending SIGBUS to the current process.
