In order to keep the code readable, move the host-save/guest-restore sequences in their own functions, with the following changes: - the hypervisor ZCR is now set from C code - ZCR_EL2 is always used as the EL2 accessor This results in some minor assembler macro rework. No functional change intended. Acked-by: Will Deacon <will@kernel.org> Signed-off-by: Marc Zyngier <maz@kernel.org>
