[IA64] disable interrupts when exiting from ia64_mca_cmc_int_handler()
SAL specification mandates that ia64_mca_log_sal_error_record() gets called with interrupts enabled, and that's why ia64_mca_cmc_int_handler() is enabling them. It however forgets to re-disable them when exiting, which triggers WARN_ON() in generic IRQ handler. Disable the interrupts again before exiting. This is analogous to a3967685745 ("[IA64] disable interrupts at end of ia64_mca_cpe_int_handler()"). Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Tony Luck <tony.luck@intel.com>
