2013-08-30	ARM: KVM: vgic: Bump VGIC_NR_IRQS to 256	Christoffer Dall
	The Versatile Express TC2 board, which we use as our main emulated platform in QEMU, defines 160+32 == 192 interrupts, so limiting the number of interrupts to 128 is not quite going to cut it for real board emulation. Note that this didn't use to be a problem because QEMU was buggy and only defined 128 interrupts until recently.

2013-06-26	ARM: KVM: Allow host virt timer irq to be different from guest timer virt irq	Anup Patel
	The arch_timer irq numbers (or PPI numbers) are implementation dependent, so the host virtual timer irq number can be different from guest virtual timer irq number. This patch ensures that host virtual timer irq number is read from DTB and guest virtual timer irq is determined based on vcpu target type.

2013-05-19	ARM: KVM: move GIC/timer code to a common location	Marc Zyngier
	As KVM/arm64 is looming on the horizon, it makes sense to move some of the common code to a single location in order to reduce duplication. The code could live anywhere. Actually, most of KVM is already built with a bunch of ugly ../../.. hacks in the various Makefiles, so we're not exactly talking about style here. But maybe it is time to start moving into a less ugly direction. The include files must be in a "public" location, as they are accessed from non-KVM files (arch/arm/kernel/asm-offsets.c). For this purpose, introduce two new locations: - virt/kvm/arm/ : x86 and ia64 already share the ioapic code in virt/kvm, so this could be seen as a (very ugly) precedent. - include/kvm/ : there is already an include/xen, and while the intent is slightly different, this seems as good a location as any Eventually, we should probably have independant Makefiles at every levels (just like everywhere else in the kernel), but this is just the first step.
