AFAIC this could go in anytime.  It's simple, self-contained and makes
sense even without Xen.

One minor nit: the IRQ value isn't negated, it's complemented.  The
comments need to be fixed.

If we really want it disambiguated then we should call it something like 'bitwise-negated' or 'ones-complemented'. 'Complemented' alone is worse than 'negated' imo, since negation is at least the usual name for the tilde operator in C while complementation is an ambiguous term unless you know the base/radix.
