Section 15.3.1.2 of the software developer manual has this to say about the RIPV bit in the IA32_MCG_STATUS register: RIPV (restart IP valid) flag, bit 0 — Indicates (when set) that program execution can be restarted reliably at the instruction pointed to by the instruction pointer pushed on the stack when the machine-check exception is generated. When clear, the program cannot be reliably restarted at the pushed instruction pointer. We need to save the state of this bit in do_machine_check() and use it in mce_notify_process() to force a signal; even if memory_failure() says it made a complete recovery ... e.g. replaced a clean LRU page.
