Geert Uytterhoeven 1630146db2 scripts/find-unused-docs: Fix massive false positives
scripts/find-unused-docs.sh invokes scripts/kernel-doc to find out if a
source file contains kerneldoc or not.

However, as it passes the no longer supported "-text" option to
scripts/kernel-doc, the latter prints out its help text, causing all
files to be considered containing kerneldoc.

Get rid of these false positives by removing the no longer supported
"-text" option from the scripts/kernel-doc invocation.

Lukas Bulwahn 06b9c26993 docs: nvdimm: use ReST notation for subsection
The ACPI Device Specific Methods (_DSM) paragraph is intended to be a
subsection of the Submit Checklist Addendum section. Dan Williams however
used Markdown notation for this subsection, which does not parse as
intended in a ReST documentation.

Change the markup to ReST notation, as described in the Specific
guidelines for the kernel documentation section in
Documentation/doc-guide/sphinx.rst.

Jonathan Corbet bcac386f3d docs: Keep up with the location of NoUri
Sphinx 2.1 moved sphinx.environment.NoUri into sphinx.errors; that produced
this warning in the docs build:

  /usr/lib/python3.7/site-packages/sphinx/registry.py:473:
    RemovedInSphinx30Warning: sphinx.environment.NoUri is deprecated.

Grab NoUri from the right place and make the warning go away.  That symbol
was only added to sphinx.errors in 2.1, so we must still import it from the
old location when running in older versions.

  This series converts a few docs in Documentation/filesystems/nfs to RST.

  Most changes are related to aesthetics and presentation, i.e. the content

 From the review, I got not only 'Reviewed-by:' tags, but also found a

realized that the first version has already sent to Linus.  I therefore
send only the nit fixes as another patch.

Konstantin Ryabitsev ab229d6202 Process: provide hardware-security list details
Fill in "..." stubs with proper links to the mailing lists's encryption
keys and service description URLs. Similarly, fix wording to specify
that multiple members of Linux Foundation's IT team have access to
internal kernel.org infrastructure, and that all of them have similar
confidentiality obligations as the IT team director.

Frank A. Cancio Bello d693b2883c docs: ftrace: Specifies when buffers get clear
Clarify a few places where the ring buffer and the "snapshot" buffer
are cleared as a side effect of an operation.

This will avoid users lost of tracing data because of these so far
undocumented behavior.

Linus Torvalds 9603e22104 Pull request for 5.5-rc2
- Update Steve Wise info
 - Fix for soft-RoCE crc calculations (will break back compatibility, but
   only with the soft-RoCE driver, which has had this bug since it was
   introduced and it is an on-the-wire bug, but will make soft-RoCE fully
   compatible with real RoCE hardware)

Pull rdma fixes from Doug Ledford:
 "A small collection of -rc fixes. Mostly. One API addition, but that's
  because we wanted to use it in a fix. There's also a bug fix that is
  going to render the 5.5 kernel's soft-RoCE driver incompatible with
  all soft-RoCE versions prior, but it's required to actually implement
  the protocol according to the RoCE spec and required in order for the
  soft-RoCE driver to be able to successfully work with actual RoCE
  hardware.

  Summary:

   - Update Steve Wise info

   - Fix for soft-RoCE crc calculations (will break back compatibility,

Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski:
 "This small series replaces all in-kernel calls to the
  userspace-focused ksys_mount() and ksys_dup() with calls to
  kernel-centric functions:

  For each replacement of ksys_mount() with do_mount(), one needs to
  verify that the first and third parameter (char *dev_name, char *type)
  are strings allocated in kernelspace and that the fifth parameter
  (void *data) is either NULL or refers to a full page (only occurence
  in init/do_mounts.c::do_mount_root()). The second and fourth
  parameters (char *dir_name, unsigned long flags) are passed by
  ksys_mount() to do_mount() unchanged, and therefore do not require
  particular care.

  Moreover, instead of pretending to be userspace, the opening of
  /dev/console as stdin/stdout/stderr can be implemented using in-kernel
  functions as well. Thereby, ksys_dup() can be removed for good"

[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"
  case, but it at least removes _some_ of the users of "treat kernel
  pointers as user pointers for our magical init sequence".

  One day we'll hopefully be rid of it all, and can initialize our
  init_thread addr_limit to USER_DS.    - Linus ]

* 'remove-ksys-mount-dup' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
  fs: remove ksys_dup()
  init: unify opening /dev/console as stdin/stdout/stderr
