Especially with poll support now in the series, don't we need a ѕigmask
argument similar to pselect/ppoll/io_pgetevents now to deal with signal
blocking during waiting for events?

Is there any way to avoid passing in the sigset_t size? If it's just a
32-bit/64-bit thing, surely the in_compat_syscall() could cover it? Or
are there other cases that need to be catered to?

As far as I can tell we never look at it, never looked at it and don't
have any plans to look at it anytime soon.  But when I tried to omit
it for io_pgetevents I got stong pushback and thus had to add the
crazy double indirection calling convention.
