So, it was never a cpumask at all; just a remnant of the use of
sigaction for interrupt handlers. We've been happily setting it
throughout the kernel since 1995.
On the assumption that it has failed to coerce the spirits of our
ancestors to land among us, I'll create a patch to remove it.

Please write good changelogs. This is not some pointless
book-keeping exercise. People will make decisions about which
kernel versions patches should be merged into, and they will want
to know if a particular patch addresses a particular problem which
they are experiencing. For this, they need information.
