Log Message:
Move softint and preemtion-related functions out of x86/x86/intr.c to
  its own file, x86/x86/x86_softintr.c
Add x86/x86/x86_softintr.c for native and XenPV
Make sure XenPV also check ci_ioending, which is used for softints.
Switch XenPV to fast softints and allow kernel preemption.
kpreempt_disable() before calling pmap_changeprot_local()
run  xen_wallclock_time() and xen_global_systime_ns() at splshed() to
  avoid being interrupted.

XXX amd64 lock stubs are racy for XPENDING
