Peter Maydell 063f12e0de KVM: arm: Reserve bit in KVM_REG_ARM encoding for secure/nonsecure ... We have a KVM_REG_ARM encoding that we use to expose KVM guest registers to userspace. Define that bit 28 in this encoding indicates secure vs nonsecure, so we can distinguish the secure and nonsecure banked versions of a banked AArch32 register. For KVM currently, all guest registers are nonsecure, but defining the bit is useful for userspace. In particular, QEMU uses this encoding as part of its on-the-wire migration format, and needs to be able to describe secure-bank registers when it is migrating (fully emulated) EL3-enabled CPUs.
