That's the memory in bytes reserved for each logical CPU in the
extended MCE Records pool. By current size of struct mce that
equates to around 2 records.

Will change it to (2 * sizeof(struct mce)) though. Feels more
accurate. Thanks for the suggestion!

Do you have any additional concerns/comments on this patchset?
