KVM: arm/arm64: remove now unneeded include directory from Makefile virt/kvm was never really a good include directory for anything else than locally included headers. With the move of iodev.h there is no need anymore to add this directory the compiler's include path, so remove it from the arm and arm64 kvm Makefile.

arm64: KVM: Move the AArch32 conditional execution to common code It would make some sense to share the conditional execution code between 32 and 64bit. In order to achieve this, let's move that code to virt/kvm/arm/aarch32.c. While we're at it, drop a superfluous BUG_ON() that wasn't that useful.

KVM: arm: introduce kvm_arm_init/setup/clear_debug This is a precursor for later patches which will need to do more to setup debug state before entering the hyp.S switch code. The existing functionality for setting mdcr_el2 has been moved out of hyp.S and now uses the value kept in vcpu->arch.mdcr_el2. As the assembler used to previously mask and preserve MDCR_EL2.HPMN I've had to add a mechanism to save the value of mdcr_el2 as a per-cpu variable during the initialisation code. The kernel never sets this number so we are assuming the bootcode has set up the correct value here. This also moves the conditional setting of the TDA bit from the hyp code into the C code which is currently used for the lazy debug register context switch code.

KVM: arm/arm64: vgic-new: enable build Now that the new VGIC implementation has reached feature parity with the old one, add the new files to the build system and add a Kconfig option to switch between the two versions. We set the default to the new version to get maximum test coverage, in case people experience problems they can switch back to the old behaviour if needed.

KVM: arm/arm64: Enable irqchip routing This patch adds compilation and link against irqchip. Main motivation behind using irqchip code is to enable MSI routing code. In the future irqchip routing may also be useful when targeting multiple irqchips. Routing standard callbacks now are implemented in vgic-irqfd: - kvm_set_routing_entry - kvm_set_irq - kvm_set_msi They only are supported with new_vgic code. Both HAVE_KVM_IRQCHIP and HAVE_KVM_IRQ_ROUTING are defined. KVM_CAP_IRQ_ROUTING is advertised and KVM_SET_GSI_ROUTING is allowed. So from now on IRQCHIP routing is enabled and a routing table entry must exist for irqfd injection to succeed for a given SPI. This patch builds a default flat irqchip routing table (gsi=irqchip.pin) covering all the VGIC SPI indexes. This routing table is overwritten by the first first user-space call to KVM_SET_GSI_ROUTING ioctl. MSI routing setup is not yet allowed.

arm/arm64: KVM: Kill CONFIG_KVM_ARM_{VGIC,TIMER} We can definitely decide at run-time whether to use the GIC and timers or not, and the extra code and data structures that we allocate space for is really negligable with this config option, so I don't think it's worth the extra complexity of always having to define stub static inlines. The !CONFIG_KVM_ARM_VGIC/TIMER case is pretty much an untested code path anyway, so we're better off just getting rid of it.

arm64: KVM: Add access handler for event counter register These kind of registers include PMEVCNTRn, PMCCNTR and PMXEVCNTR which is mapped to PMEVCNTRn. The access handler translates all aarch32 register offsets to aarch64 ones and uses vcpu_sys_reg() to access their values to avoid taking care of big endian. When reading these registers, return the sum of register value and the value perf event counts.
