Subject: [PATCH 0/5] cleanups, fixes, and progress towards avoiding "make headers"

Eventually, once the build succeeds on a sufficiently old distro, the
idea is to delete $(KHDR_INCLUDES) from the selftests/mm build, and then
after that, from selftests/lib.mk and all of the other selftest builds.

For now, this series merely achieves a clean build of selftests/mm on a
not-so-old distro: Ubuntu 23.04:

1. Add __NR_mseal.

2. Add fs.h, taken as usual from a snapshot of ./usr/include/linux/fs.h
after running "make headers". This is how we have agreed to do this sort
of thing, see [1].

3. Add a few selected prctl.h values that the ksm and mdwe tests require.

[1] commit e076eaca5906 ("selftests: break the dependency upon local
header files")

John Hubbard (5):
  selftests/mm: mseal, self_elf: fix missing __NR_mseal
  selftests/mm: fix vm_util.c build failures: add snapshot of fs.h
  mm/selftests: kvm, mdwe fixes to avoid requiring "make headers"
  selftests/mm: mseal, self_elf: factor out test macros and other
    duplicated items
  selftests/mm: mseal, self_elf: rename TEST_END_CHECK to
    REPORT_TEST_PASS
