Subject: [PATCH 2/2] asm-generic: rwsem: de-PPCify rwsem.h
Date: Fri, 21 Feb 2014 17:22:27 +0000	[thread overview]
Message-ID: <1393003347-24958-2-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1393003347-24958-1-git-send-email-will.deacon@arm.com>

asm-generic/rwsem.h used to live under arch/powerpc. During its
liberation to common code, a few references to its former home where
preserved, in particular the definition of RWSEM_ACTIVE_MASK is
predicated on CONFIG_PPC64.

This patch updates the ifdefs and comments to architecturally neutral
versions.
