From 6ff0966052c46efb53980b8a1add2e7b49c9f560 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Sun, 13 Sep 2015 03:25:26 +0100 Subject: ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000 There is a 12MB unused region in our memory map between the vmalloc and fixmap areas. This became unused with commit e9da6e9905e6, confirmed with commit 64d3b6a3f480. We also have a 8MB guard area before the vmalloc area. With the default 240MB vmalloc area size and the current VMALLOC_END definition, that means the end of low memory ends up at 0xef800000 which is unfortunate for 768MB machines where 8MB of RAM is lost to himem. Let's move VMALLOC_END to 0xff800000 so the guard area won't chop the top of the 768MB low memory area while keeping the default vmalloc area size unchanged and still preserving a gap between the vmalloc and fixmap areas.
