Subject: [PATCH 03/11] ARM: hwcaps: use shifts instead of hardcoded constants
Date: Mon, 6 Jun 2011 17:55:47 +0100 [thread overview]
Message-ID: <1307379355-13802-4-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1307379355-13802-1-git-send-email-will.deacon@arm.com>
The HWCAP numbers are defined as constants, each one being a power of 2.
This has become slightly unwieldy now that we have reached 32k.
This patch changes the HWCAP defines to use (1 << n) instead of coding
the constant directly. The values remain unchanged.
