[merged] userfaultfd-selftest-vm-allow-to-build-in-vm-directory.patch removed from -mm tree

[akpm]

The patch titled
     Subject: userfaultfd: selftest: vm: allow to build in vm/ directory
has been removed from the -mm tree.  Its filename was
     userfaultfd-selftest-vm-allow-to-build-in-vm-directory.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Andrea Arcangeli <aarcange@redhat.com>
Subject: userfaultfd: selftest: vm: allow to build in vm/ directory

linux/tools/testing/selftests/vm $ make
gcc -Wall -I ../../../../usr/include     compaction_test.c -lrt -o /compaction_test
/usr/lib/gcc/x86_64-pc-linux-gnu/4.9.4/../../../../x86_64-pc-linux-gnu/bin/ld:
cannot open output file /compaction_test: Permission denied
collect2: error: ld returned 1 exit status
make: *** [../lib.mk:54: /compaction_test] Error 1

Since commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT")
selftests/vm build fails if run from the "selftests/vm" directory, but it
works in the selftests/ directory.  It's quicker to be able to do a local
vm-only build after a tree wipe and this patch allows for it again.
