Some systems may report spurious MCA errors. In general, spurious MCA errors may be disabled by clearing a particular bit in MCA_CTL. However, clearing a bit in MCA_CTL may not be recommended for some errors, so the only option is to ignore them. An MCA error is printed and handled after it has been added to the MCE event pool. So an MCA error can be ignored by not adding it to that pool in the first place. Add such a filtering function.
