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);
^

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:
