Subject: [PATCH 2/2] ARM: mm: allow set_memory_*() to be used on the vmalloc region
Date: Mon, 21 Nov 2016 16:08:40 +0000 [thread overview]
Message-ID: <E1c8r96-0007wR-JK@rmk-PC.armlinux.org.uk> (raw)
We can allow modules to be loaded into the vmalloc region, where they
should also benefit from the same protections as those loaded into
the more efficient module region. Allow these functions to operate
there as well.
Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
