kaf24@firebug.cl.cam.ac.uk ca039d0244 hvm: Fix platform-irq handling in presence of irqbalance daemon. 
The HVM guest did not respond when PV-on-HVM driver was tested on
the following conditions.

1. RHEL4u4
2. vcpu 4
3. irqbalance on
4. pv-on-hvm driver used.

Eventhandler did not work because IRQ was delivered to another vcpu by
irqbalance.

Steven Smith 47132af16f [PV-ON-HVM] Don't generate lots of spurious interrupts when using event 
channel upcalls.

The issue here was that the Xen platform PCI interrupt is only updated
when you return from the hypervisor into guest context, and so remained
asserted for a short interval after the interrupt handler ran.  If
it happened that the first subsequent trap to the hypervisor was
for unmasking the 8259 interrupt again, the unmasking caused the interrupt
to be reinjected.  This caused an edge on the chaining interrupt from
the slave PIC to the master.  The platform interrupt on the slave
would then be cleared as we returned to the guest, and so you
eventually end up injecting an interrupt on the master chained
interrupt with nothing pending on the slave, which shows up as
a spurious interrupt in the guest.

Steven Smith 65ae4fc8cd [HVM][LINUX][TOOLS] Make xm {shutdown|reboot} do something sensible for HVM 
domains with PV drivers loaded.  This patch creates a new PV-on-HVM
module, reboot.ko, which, when loaded, creates control/reboot_module
in the store.  The tools notice this, and disable the watch which would
normally destroy HVM domains which are the target of an xm shutdown
command, allowing the reboot module to shut the domain down cleanly.
