As per a discussion with Muhammad Usama Anjum [1], the following is how
one is supposed to build selftests:

    make headers && make -C tools/testing/selftests/mm

Change the selftest build system's lib.mk to fail out with a helpful
message if that prerequisite "make headers" has not been done yet.

Test cachestat on a newly created file, /dev/ files, /proc/ files and a

huge pages since tmpfs supports huge pages).

RISC-V, so I've added some infrastructure for those as well.

This patch will add the new test, which covers the prctl call with
PR_SET_VMA command. The test tries to give a name to the anonymous
VMA within the process memory map, and then checks the result of
the operation by parsing 'maps' virtual file.

Additionally, the test tries to call the prctl PR_SET_VMA command
with invalid arguments, and checks the error codes for correctness.

At the moment anonymous VMA naming through prctl call functionality
is not covered with any tests, so I think implementing it makes sense.

In version 2 of this patch I consider the selftest Makefile rule about
TARGETS entries order - I moved the 'prctl' entry in the Makefile to
follow the lexicographic order. In version 1 it was placed at the
end of the list.

Pull MM updates from Andrew Morton:

 - Daniel Verkamp has contributed a memfd series ("mm/memfd: add
   F_SEAL_EXEC") which permits the setting of the memfd execute bit at
   memfd creation time, with the option of sealing the state of the X
   bit.

 - Peter Xu adds a patch series ("mm/hugetlb: Make huge_pte_offset()
   thread-safe for pmd unshare") which addresses a rare race condition
   related to PMD unsharing.

   Moola, Sidhartha Kumar and Lorenzo Stoakes

   which does perform some memcg maintenance and cleanup work.

 - SeongJae Park has added DAMOS filtering to DAMON, with the series
   "mm/damon/core: implement damos filter".

   These filters provide users with finer-grained control over DAMOS's
   actions. SeongJae has also done some DAMON cleanup work.

 - Kairui Song adds a series ("Clean up and fixes for swap").

 - Vernon Yang contributed the series "Clean up and refinement for maple
   tree".

   writeable+executable mappings.

   The previous BPF-based approach had shortcomings. See "mm: In-kernel
   support for memory-deny-write-execute (MDWE)".

   regression in compaction via his series "Fix excessive CPU usage
   during compaction".

 - Christoph Hellwig does some vmalloc maintenance work in the series
   "cleanup vfree and vunmap".

   /proc/kcore better represent the real state of things in his series
   "mm/vmalloc.c: allow vread() to read out vm_map_ram areas".

 - Jason Gunthorpe rationalized the GUP system's interface to the rest
   of the kernel in the series "Simplify the external interface for
   GUP".

 - SeongJae Park wishes to migrate people from DAMON's debugfs interface
   over to its sysfs interface. To support this, we'll temporarily be
   printing warnings when people use the debugfs interface. See the
   series "mm/damon: deprecate DAMON debugfs interface".

 - Andrey Konovalov provided the accurately named "lib/stackdepot: fixes
   and clean-ups" series.

 - Huang Ying has provided a dramatic reduction in migration's TLB flush
   IPI rates with the series "migrate_pages(): batch TLB flushing".

Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Conflicts:
* drivers/hid/i2c-hid/Kconfig:
  commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected
  when I2C_HID_OF_ELAN is")
  the resolution is simple enough: just drop the "default" and "select"
  lines as the new commit from Arnd is doing
