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.
