The following series implements support for the virtual generic
interrupt controller architecture for KVM/ARM.
Changes since v2:
- Get rid of hardcoded guest cpu and distributor physical addresses
and instead provide the address through the KVM_SET_DEVICE_ADDRESS
ioctl.
- Fix level/edge bugs
- Fix reboot bug: retire queued, disabled interrupts
This patch series can also be pulled from:
