From 7329bbeb92740f35d64a8860ae7837ff4db27fe0 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Tue, 13 Dec 2011 09:27:58 -0800 Subject: HWPOISON: Add code to handle "action required" errors. Add new flag bit "MF_ACTION_REQUIRED" to be used by machine check code to force a signal with si_code = BUS_MCEERR_AR in the case where the error occurs in processor execution context. Pass the flags argument along call chain: memory_failure() hwpoison_user_mappings() kill_procs() kill_proc() Drop the "_ao" suffix from kill_procs_ao() and kill_proc_ao() since they can now handle "action required" as well as "action optional" errors.
