Subject: [PATCH 0/2] selftests/mlock2: Build warning fixes on Debian/m68k 4.0

	Hi,

The following 2 patches are needed to fix build warnings on Debian/m68k
4.0.

However, after wiring up the mlock2 syscall, the test fails with:

# ./mlock2-tests
fread kpageflags: Success
# 

as the fread() call returns 0, not 1.

The original commit description for the test said "Note that the limit
test needs to be run a normal user.". But running it as a non-root user
also fails:

$ ./mlock2-tests 
fopen kpageflags: Permission denied
$ ls -l /proc/kpageflags 
-r-------- 1 root root 0 Nov  9 11:05 /proc/kpageflags
$

What am I missing?

Thanks!

Geert Uytterhoeven (2):
  selftests/mlock2: Add missing #define _GNU_SOURCE
  selftests/mlock2: Add ULL prefix to 64-bit constants
