Last time I tested this on sparc64 (the only current user of ->mask) it
appeared to work. The following patch makes irqaction's ->mask a cpumask
as it was intended to be and wraps up the rest of the sweep. Only struct
irqaction is usefully greppable, so there may be some assignments to
->mask missing still. This removes more code than it adds.

Compiletested i386 and sparc64, runtime tested on sparc64 in a prior
incarnation. vs. 2.6.7-rc3-mm1
