Ok,
my main intention for this is patch 1/2 which enables MCA by default. I
still see bugreports where CONFIG_X86_MCE is disabled and this is a bad
idea so turning it on by default makes sense to me.
The second patch is only a cleanup.
Thanks.

MCA is the basic support for hardware error logging and reporting, and
it is majorly unwise to run without it so enable machine check software
support by default on x86.
