Subject: [PATCH 3.12 15/27] crash_dump: fix compilation error (on MIPS at least)

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Qais Yousef <qais.yousef@...tec.com>

commit 5a610fcc7390ee60308deaf09426ada87a1eeec2 upstream.

  In file included from kernel/crash_dump.c:2:0:
  include/linux/crash_dump.h:22:27: error: unknown type name `pgprot_t'

when CONFIG_CRASH_DUMP=y

The error was traced back to commit 9cb218131de1 ("vmcore: introduce
remap_oldmem_pfn_range()")

include <asm/pgtable.h> to get the missing definition
