Subject: [PATCH 2/3] ARM64: attribute argument to create_sections() is 64bit
Date: Tue, 31 Mar 2020 10:01:08 +0200 [thread overview]
Message-ID: <20200331080109.24402-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200331080109.24402-1-s.hauer@pengutronix.de>
The attribute argument to create_sections() is 64bit, so pass in a
64bit variable. This is done in preparation for using some of the upper
bits in the (UN)CACHED_MEM defines.
