Subject: [PATCH 4.4 16/21] x86: cpufeatures: Sort feature word 7
Date: Fri, 9 Aug 2019 15:45:20 +0200 [thread overview]
Message-ID: <20190809134242.234053013@linuxfoundation.org> (raw)
In-Reply-To: <20190809134241.565496442@linuxfoundation.org>
From: Ben Hutchings <ben@decadent.org.uk>
This will make it clearer which bits are allocated, in case we need to
assign more feature bits for later backports.
