Subject: KVM: arm/arm64: Move phys_timer_emulate function
Patch-mainline: v4.15-rc1
Git-commit: cda93b7aa4657f2a9df28d56df8259226be8b0e9
References: bsc#1077761
We are about to call phys_timer_emulate() from kvm_timer_update_state()
and modify phys_timer_emulate() at the same time. Moving the function
and modifying it in a single patch makes the diff hard to read, so do
this separately first.
No functional change.
