Subject: [PATCH AUTOSEL 5.4 25/32] csky: Fixup msa highest 3 bits mask
Date: Fri, 22 May 2020 10:50:37 -0400	[thread overview]
Message-ID: <20200522145044.434677-25-sashal@kernel.org> (raw)
In-Reply-To: <20200522145044.434677-1-sashal@kernel.org>

From: Liu Yibin <jiulong@linux.alibaba.com>

[ Upstream commit 165f2d2858013253042809df082b8df7e34e86d7 ]

Just as comment mentioned, the msa format:

 cr<30/31, 15> MSA register format:
 31 - 29 | 28 - 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0
   BA     Reserved  SH  WA  B   SO SEC  C   D   V

So we should shift 29 bits not 28 bits for mask
