Subject: [PATCH v2 5/6] ARM: use "* SZ_1M" rather than "<< 20"
Date: Fri, 28 May 2021 11:11:52 +0100 [thread overview]
Message-ID: <E1lmZT6-0005U2-8e@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20210518120633.GW12395@shell.armlinux.org.uk>
Make the default vmalloc size clearer by using a more natural
multiplication by SZ_1M rather than a shift left by 20 bits.
