swsusp_arch_suspend() actually saves all cpu register contents on hibernation. Machine checks must be disabled since swsusp_arch_suspend() stores register contents to their lowcore save areas. That's the same place where register contents on machine checks would be saved. To avoid register corruption disable machine checks. We must also disable machine checks in the new psw mask for program checks, since swsusp_arch_suspend() may generate program checks.
