From mboxrd@z Thu Jan 1 00:00:00 1970 From: rmk+kernel@armlinux.org.uk (Russell King) Date: Mon, 21 Nov 2016 16:08:40 +0000 Subject: [PATCH 2/2] ARM: mm: allow set_memory_*() to be used on the vmalloc region Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
