Hi,
This patch set contains a fully working implementation of the in-kernel MPIC
from Scott with a few fixups and a new version of my irqfd generalization
patch set.
v1 -> v2:
- depend on CONFIG_ defines rather than __KVM defines
- fix compile issues
- fix the kvm_irqchip{,s} typo
v2 -> v3:
- make mpic pointer type safe
- add wmb before setting global mpic variable
- make eoi notification happen unlockedly
- add IRQ routing documentation
- announce mpic availability after its creation
- fix pr_debug again
v3 -> v4:
- update documentation
- fix spin locks
- remove default routing map
- move eoi notify code into eoi register handler
- fix header
- new: KVM: IA64: Carry non-ia64 changes into ia64
- new: kvm: destroy emulated devices on VM exit
- new: kvm/ppc/mpic: Eliminate mmio_mapped
