From 04fef057003c207ff4d9f22d2127aee2f9abecd0 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Sat, 5 Aug 2017 22:51:35 +0200 Subject: KVM: arm64: Remove noop calls to timer save/restore from VHE switch The VHE switch function calls __timer_enable_traps and __timer_disable_traps which don't do anything on VHE systems. Therefore, simply remove these calls from the VHE switch function and make the functions non-conditional as they are now only called from the non-VHE switch path.
