Well, but I do care so that when you leave and start doing something
else, people after you can still read and maintain that code.

Are you kidding me? Only Intel has CMCI.

Now, if some other vendor needs correctable errors interrupt rate
throttling, they can carve it out, make it generic, and move it to mce.c.

Otherwise, it belongs in mce_intel.c. For the same reason AMD error
thresholding code belongs to mce_amd.c.

Jeez.
