Subject: [PATCH 6/6] arm64/cpufeature: Replace all open bits shift encodings with macros
Date: Tue, 28 Jan 2020 18:09:09 +0530 [thread overview]
Message-ID: <1580215149-21492-7-git-send-email-anshuman.khandual@arm.com> (raw)
In-Reply-To: <1580215149-21492-1-git-send-email-anshuman.khandual@arm.com>
There are many open bits shift encodings for various CPU ID registers that
are scattered across cpufeature. This replaces them with register specific
sensible macro definitions. This should not have any functional change.
