2014-05-20x86, microcode: Add a disable chicken bitBorislav Petkov1-0/+37
Add a cmdline param which disables the microcode loader. This is useful mostly in debugging situations where we want to turn off microcode loading, both early from the initrd and late, as a means to be able to rule out its influence on the machine.

2014-01-13x86, microcode: Move to a proper locationBorislav Petkov1-0/+141
We've grown a bunch of microcode loader files all prefixed with "microcode_". They should be under cpu/ because this is strictly CPU-related functionality so do that and drop the prefix since they're in their own directory now which gives that prefix. :) While at it, drop MICROCODE_INTEL_LIB config item and stash the functionality under CONFIG_MICROCODE_INTEL as it was its only user.
