Caller
NameDescribe
text_poke_earlyxt_poke_early - Update instructions on a live kernel at boot time*@addr: address to modify*@opcode: source of the copy*@len: length to copy* When you use this code to patch more than one byte of an instruction
do_sync_core
machine_check_pollPoll for corrected events or events that happened before reset.* Those are just logged through /dev/mcelog.* This is executed in standard interrupt context.* Note: spec recommends to panic for fatal unsignalled* errors here
do_machine_checkThe actual machine check handler. This only handles real* exceptions when something got corrupted coming in through int 18.* This is executed in NMI context not subject to normal locking rules. This* implies that most kernel services cannot be safely used
