Printing message to console from MCA/INIT handler is useful, however doing oops_in_progress = 1 in them exactly makes something in kernel wrong. Especially it sounds ugly if system goes wrong after returning from recoverable MCA. This patch adds ia64_mca_printk() function that collects messages into temporary-not-so-large message buffer during in MCA/INIT environment and print them out later, after returning to normal context or when handlers determine to down the system. Also this print function is exported for use in extensional MCA handler. It would be useful to describe detail about recovery. NOTE: I don't think it is sane thing if temporary message buffer is enlarged enough to hold whole stack dumps from INIT, so buffering is disabled during stack dump from INIT-monarch (= default_monarch_init_process). please fix it in future.
