Subject: crash_dump: fix compilation error (on MIPS at least)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5a610fcc7390ee60308deaf09426ada87a1eeec2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

crash_dump: fix compilation error (on MIPS at least)

  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
