Peter Anvin <hpa@xxxxxxxxx> CommitDate: Thu, 28 May 2009 09:24:15 -0700 x86, mce: use extended sysattrs for the check_interval attribute. Instead of using own callbacks use the generic ones provided by the sysdev later. This finally allows to get rid of the ugly ACCESSOR macros. Should also save some text size.
