[PATCH v5 00/12] KVM/ARM vGIC support

[Christoffer Dall]

The following series implements support for the virtual generic
interrupt controller architecture for KVM/ARM.

This patch series can also be pulled from:
    git://github.com/virtualopensystems/linux-kvm-arm.git
            branch: kvm-arm-v15-vgic

Changes since v4:
 - Large number of commenting and formatting changes
 - Don't rely on the vgic_hcr default value
 - Fix bug in irq_fgx expand/collapse functions
 - Sanitize use of bitmaps
 - Do not use elrsr when queueing an interrupt
 - Deassert SGIs and SPIs that have already been queued
 - Set VMCR to 0 on vcpu init
 - Compute number of list registers once at init time
 - Restructure bytemap/bitmap accessor functions
 - Improve readability by adding accessor functions
 - Define GICH_ constants in gic.h and use these in the vgic code
 - Explain SGI handling in comment
 - Error patch and return value fixes and cleanups
 - Use defines instead of all hardcoded IRQ numbers
 - Refactor level interrupt handling
 - Fix several maintenace-interrupt related bugs
 - Add CPU hotplug notifier

Changes since v3:
 - Change struct kvm_device_addr to use 64 bits for ID field

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
