From c3052594c8ded984ceab3725f63990dfdea1e58f Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Wed, 25 Apr 2018 16:28:26 +0200 Subject: ACPICA: provide abstraction for raw_spinlock_t Provide a new lock type acpi_raw_spinlock which is implemented as raw_spinlock_t on Linux. This type should be used in code which covers small areas of code and disables interrupts only for short time even on a realtime OS. There is a fallback to spinlock_t if an OS does not provide an implementation for acpi_raw_spinlock. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Rafael J.
