From e6ce9d741163af0b846637ce6550ae8a671b1588 Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Wed, 5 Apr 2023 16:17:06 +0200 Subject: locking/atomic: Add generic try_cmpxchg{,64}_local() support Add generic support for try_cmpxchg{,64}_local() and their falbacks. These provides the generic try_cmpxchg_local family of functions from the arch_ prefixed version, also adding explicit instrumentation.
