Subject: [PATCH 03/27] ARM: Add _32 suffix to aarch32 specific filenames
Date: Fri, 12 May 2023 13:09:44 +0200	[thread overview]
Message-ID: <20230512111008.1120833-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230512111008.1120833-1-s.hauer@pengutronix.de>

Several files in arch/arm/cpu/ have 32bit and 64bit versions. The
64bit versions have a _64 suffix, but the 32bit versions have none.
This can be confusing sometimes as one doesn't know if a file is
32bit specific or common code.

Add a _32 suffix to the 32bit files to avoid this confusion.
