From 5a354412567d7de81d69b6ac61c3b7fcebbe497e Mon Sep 17 00:00:00 2001 From: Andrew Murray Date: Thu, 13 Jun 2019 13:51:02 +0100 Subject: clocksource/drivers/arm_arch_timer: Extract elf_hwcap use to arch-helper Different mechanisms are used to test and set elf_hwcaps between ARM and ARM64, this results in the use of ifdeferry in this file when setting/testing for the EVTSTRM hwcap. Let's improve readability by extracting this to an arch helper.
