2015-01-12arm64: KVM: Fix HCR setting for 32bit guestsMarc Zyngier
Commit b856a59141b1 (arm/arm64: KVM: Reset the HCR on each vcpu when resetting the vcpu) moved the init of the HCR register to happen later in the init of a vcpu, but left out the fixup done in kvm_reset_vcpu when preparing for a 32bit guest. As a result, the 32bit guest is run as a 64bit guest, but the rest of the kernel still manages it as a 32bit. Fun follows. Moving the fixup to vcpu_reset_hcr solves the problem for good.

2013-06-12arm64: KVM: enable initialization of a 32bit vcpuMarc Zyngier
Wire the init of a 32bit vcpu by allowing 32bit modes in pstate, and providing sensible defaults out of reset state. This feature is of course conditioned by the presence of 32bit capability on the physical CPU, and is checked by the KVM_CAP_ARM_EL1_32BIT capability.
