Patch 2 is stolen from Eric's series and is necessary for these\npatches to compile as well. Patch 3 includes the core support for\nmapped level-triggered interrupts. Patch 4 handles guest MMIO acess to\nthe virtual distributor. Patch 5 moves some code around for patch 6.\nPatch 6 implements an optimization for the timer. The last two patches\ncould be deferred until the timer optimization series.\n\nBased on v4.13-rc7.\n\nThanks,\n-Christoffer\n\nChanges since v1:\n - Added necessary changes to the timer (Patch 1)\n - Added handling of guest MMIO accesses to the virtual distributor\n (Patch 4)\n - Addressed Marc's comments from the initial RFC (mostly renames)\n\nChristoffer Dall (5):\n KVM: arm/arm64: Don't cache the timer IRQ level\n KVM: arm/arm64: vgic: Support level-triggered mapped interrupts\n KVM: arm/arm64: Support VGIC dist pend/active changes for mapped IRQs\n KVM: arm/arm64: Rearrange kvm_vgic_[un]map_phys code in vgic.c\n KVM: arm/arm64: Provide a vgic interrupt line level sample function\n\nEric Auger (1):\n KVM: arm/arm64: vgic: restructure kvm_vgic_(un)map_phys_irq\n\n include/kvm/arm_vgic.h | 19 +++++++++--\n virt/kvm/arm/arch_timer.c | 52 +++++++++++++-----------------\n virt/kvm/arm/vgic/vgic-mmio.c | 27 ++++++++++++++++\n virt/kvm/arm/vgic/vgic-v2.c | 29 +++++++++++++++++\n virt/kvm/arm/vgic/vgic-v3.c | 29 +++++++++++++++++\n virt/kvm/arm/vgic/vgic.c | 75 ++++++++++++++++++++++++++++++++++++-------\n virt/kvm/arm/vgic/vgic.h | 8 +++++\n 7 files changed, 196 insertions(+), 43 deletions(-)"}
