Subject: [PATCH 1/4] arch,cmpxchg: Remove tas() definitions
Date: Tue, 27 Oct 2015 12:53:48 -0700	[thread overview]
Message-ID: <1445975631-17047-2-git-send-email-dave@stgolabs.net> (raw)
In-Reply-To: <1445975631-17047-1-git-send-email-dave@stgolabs.net>

It seems that 5dc12ddee93 (Remove tas()) missed some files. Correct
this and fully drop this macro, for which we should be using cmpxchg
like calls.
