From: Helge Deller Date: Tue, 17 May 2022 15:01:12 +0000 (+0200) Subject: parisc: Fix wrong comment for shr macro X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=be6aee1392c46cd6f537aea75b1ce7ec427d36f4;p=linux.git parisc: Fix wrong comment for shr macro The comment that the source and target register can not be the same is wrong. Instead on PA2.0 usage of extru can clobber upper 32-bits. This patch fixes the comment.
