Subject: [PATCH v2 1/6] ARM: change vmalloc_min to be unsigned long
Date: Fri, 28 May 2021 11:11:31 +0100	[thread overview]
Message-ID: <E1lmZSl-0005Sa-On@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20210518120633.GW12395@shell.armlinux.org.uk>

vmalloc_min is currently a void pointer, but everywhere its used
contains a cast - either to a void pointer when setting or back to
an integer type when being used. Eliminate these casts by changing
its type to unsigned long.
