John Baldwin f2e3bfc074 Make machine check exception logging more readable. On newer Intel systems, ... an uncorrected ECC error tends to fire on all CPUs in a package simultaneously and the current printf hacks are not sufficient to make the messages legible. Instead, use the existing mca_lock spinlock to serialize calls to mca_log() and change the machine check code to panic directly when an unrecoverable error is encoutered rather than falling back to a trap_fatal() call in trap() (which adds nearly a screen-full of logging messages that aren't useful for machine checks).
