x86/mce: Provide boot argument to honour bios-set CMCI threshold
The ACPI spec doesn't provide for a way for the bios to pass down recommended thresholds to the OS on a _per-bank_ basis. This patch adds a new boot option, which if passed, tells Linux to use CMCI thresholds set by the bios. As fail-safe, we initialize threshold to 1 if some banks have not been initialized by the bios and warn the user. Signed-off-by:Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com> Signed-off-by:
