From a889a23a98fee183c9b6b0b14b2fd70583429c5e Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 15 Sep 2020 12:31:59 +0200 Subject: ACPI: processor: Use CPUIDLE_FLAG_TLB_FLUSHED Make acpi_processor_idle() use the generic TLB flushing code. This again removes RCU usage after rcu_idle_enter(). (XXX make every C3 invalidate TLBs, not just C3-BM) Signed-off-by: Peter Zijlstra (Intel) Tested-by: Borislav Petkov Signed-off-by: Rafael J.
