linux-next: build failure after merge of the tip tree

[Stephen Rothwell]

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

arch/x86/power/hibernate_64.c: In function 'hibernation_e820_save':
arch/x86/power/hibernate_64.c:236:15: error: passing argument 1 of 'get_e820_md5' from incompatible pointer type [-Werror=incompatible-pointer-types]
  get_e820_md5(&e820_saved, buf);
               ^
arch/x86/power/hibernate_64.c:203:12: note: expected 'struct e820map *' but argument is of type 'struct e820map **'

Caused by commit

  475339684ef1 ("x86/e820: Prepare e280 code for switch to dynamic storage")

interacting with commit

  6f95ad2b6162 ("PM / hibernate: Verify e820 memory map by MD5 digest")

from the pm tree.

I have applied the following merge fix patch:
