Subject: [PATCH] ARM: ux500: Enable HIGHMEM in the u8540 defconfig
Date: Fri, 31 May 2013 16:09:06 +0100 [thread overview]
Message-ID: <1370012946-7374-1-git-send-email-lee.jones@linaro.org> (raw)
In order to utilise all of the memory located on ux500 based devices
we have to enable HIGHMEM. Without it the kernel truncates memory down
to what's left after the PAGE_OFFSET has been applied, which doesn't
leave an awful lot, especially if we're running large rootfs' such
as full Linux desktop distributions or Android.
