Log message:
pci_intr_establish_cpu() for establishing an interrupt no a specific cpu.
the cpu is specified by a struct cpu_info *, which should generally
come from an intrmap.
this is adapted from a diff that patrick@ sent round a few years
ago for a pci_intr_map_msix_cpuid, where you asked for an msi vector
on a specific cpu, and then called pci_intr_establish with the
handle you get. kettenis pointed out that it's hard on some archs
to carry cpu on a pci interrupt handle, so i tweaked it to turn it
into a pci_intr_establish_cpu instead.
jmatthew@ and i (but mostly jmatthew@ to be honest) have been
experimenting with this api on multiple archs and it is working out
well. i'm putting this diff in now on amd64 so people can kick the
tyres a bit.
tested with hacked up vmx(4), ix(4), and mcx(4)
