[Xen-devel] [PATCH RFC 0/3] Move RTC interrupt injection back into the vpt code.


This series implements the most recent idea I was proposing about
reworking the RTC PF interrupt injection.

Patch 1 switches handling the !PIE case to calculate the right answer
for REG_C.PF on demand rather than running the timers.
Patch 2 switches back to the old model of having the vpt code control
the timer interrupt injection; this is the fix for the w2k3 hang.
Patch 3 is just a minor cleanup, and not particularly necessary.

N.B. In its current state it DOES NOT WORK.  I got distracted by
other things today and didn't get a chance to finish working on it,
but I wanted to send it out for feedback on the general approach.
If it seems broadly acceptable then either I can pick it up again next
week or maybe Andrew can look at fixing it.
