We currently don't allow resetting mapped IRQs from userspace, because
their state is controlled by the hardware. But we do need to reset the
state when the VM is reset, so we provide a function for the 'owner' of
the mapped interrupt to reset the interrupt state.
Currently only the timer uses ma

We already have the percpu area for the host cpu state, which points to
the VCPU, so there's no need to store the VCPU pointer on the stack on
every context switch. We can be a little more clever and just use

There's a semantic difference between the EL1 registers that control
operation of a kernel running in EL1 and EL1 registers that only control
userspace execution in EL0. Since we can defer saving/restoring the

Hi; I've just noticed a bug in QEMU where we weren't migrating
Secure-bank register state for AArch32 emulated guest correctly, which
turns out to be intertwined with how KVM defines its index values for
cp15 registers in the KVM_REG_ARM_* encoding.
The problem is that QEMU defines the on-the-wire

V1.1 Calling Convention to mitigate CVE-2017-5715. This patch uses
the standard call SMCCC_ARCH_WORKAROUND_1 for Falkor chips instead
