From 736d474f0fafd1486f178570bc47660ee9dfdef8 Mon Sep 17 00:00:00 2001 From: "Suzuki K. Poulose" Date: Wed, 21 Jan 2015 12:43:10 +0000 Subject: arm64: Consolidate hotplug notifier for instruction emulation As of now each insn_emulation has a cpu hotplug notifier that enables/disables the CPU feature bit for the functionality. This patch re-arranges the code, such that there is only one notifier that runs through the list of registered emulation hooks and runs their corresponding set_hw_mode. We do nothing when a CPU is dying as we will set the appropriate bits as it comes back online based on the state of the hooks. Signed-off-by: Mark Rutland Signed-off-by: Suzuki K.
