From bd31b85960a7fcb2d7ede216460b8da71a88411c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 3 Jul 2009 08:44:46 -0500 Subject: locking, ARM: Annotate low level hw locks as raw Annotate the low level hardware locks which must not be preempted. In mainline this change documents the low level nature of the lock - otherwise there's no functional difference. Lockdep and Sparse checking will work as usual.
