[PULL 13/50] arm64: KVM: Make kvm_skip_instr32 available to HYP

From: Christoffer Dall <hidden>
Date: 2016-09-27 18:05:21
Also in: kvm, kvmarm
Subsystem: kernel virtual machine (kvm), the rest · Maintainers: Paolo Bonzini, Linus Torvalds

From: Marc Zyngier <redacted>

As we plan to do some emulation at HYP, let's make kvm_skip_instr32
as part of the hyp_text section. This doesn't preclude the kernel
from using it.
