  vl: Move cpu_synchronize_all_states() into qemu_system_reset() (2016-04-05 
10:49:10 +1000)

ppc patch queue for 2016-03-24

Three bugfixes for target-ppc, pseries machine type and related devices.

1. Fix a bug in the core code where kvm_vcpu_dirty would not be set
   before the very first system reset.  This meant that if things in
   the reset path did their own cpu_synchronize_state() it would pull
   stale data out of KVM.

   On ppc this, in combination with a previous cleanup meant that the
   MSR would be zeroed before entry, instead of correctly having the
   SF (64-bit mode) bit set.

2. Allow immediate detach of hot-added PCI devices which haven't yet
   been announced to the guest.

   This fixes a regression: because of a case where we now defer
   announcement of non-zero functions to the guest, an incorrect
   hot-add of such a device can't be backed out until the add is
   completed, which is counter-intuitive to say the least.

3. Fix migration of alternate interrupt locations.  The location of
   interrupt vectors can be affected by the LPCR, and we weren't
   correctly recalculating this after migration of a non-standard LPCR


Two of the three patches here began life as cleanups or preliminaries
for new features, however they also fix real bugs.  They're
sufficiently small that I don't think including them for 2.6 is any
riskier than any other approach to fixing the bugs in question.
