c69f22f25f Replace HTTP links with HTTPS ones: Documentation/filesystems
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

7d9c29bb6c MAINTAINERS: use my kernel.org address
There were enough problems with suse.{com,cz} MTAs recently. I am bored
by restoring lost e-mails from public archives. Let's switch (all) my
MAINTAINERS addresses to @kernel.org and forward the e-mails there as I
wish.

And add the whole history to .mailmap.

9aa1ccb4e5 docs: f2fs: fix a broken table
Commit ed318a6cc0 ("fscrypt: support test_dummy_encryption=v2") added an
entry to the massive option table in Documentation/filesystems/f2fs.txt.
The option was too wide for the formatting of the table, though, leading to
a verbose and ugly warning starting with:

    Documentation/filesystems/f2fs.rst:229: WARNING: Malformed table.
    Text in column margin in table line 126.

Fixing this requires formatting the whole table; let's hear it for Emacs
query-replace-regexp.

2f444efdaa docs: Don't push Sphinx upgrades quite so readily
The sphinx-pre-install script will put out a verbose message recommending
an upgrade for anybody running less than 2.4.4 - which was only released in
March.  So *everybody* will see that warning at this point.  Let's only
warn if the user is below our generally recommended version (1.7.9
currently).

It might be good to put out a warning if people are explicitly making PDF
files, but would need to be done in a different place and relatively few
people do that.

There are several files that I was unable to find a proper place

Let's place those stuff behind the carpet, as we'd like to keep the

We can later discuss and move those into better places.

4a87b197c1 Add additional LSM hooks for SafeSetID
SafeSetID is capable of making allow/deny decisions for set*uid calls
 on a system, and we want to add similar functionality for set*gid
 calls. The work to do that is not yet complete, so probably won't make
 it in for v5.8, but we are looking to get this simple patch in for
 v5.8 since we have it ready. We are planning on the rest of the work
 for extending the SafeSetID LSM being merged during the v5.9 merge
 window.
 
 This patch was sent to the security mailing list and there were no objections.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter
set*uid() syscalls according to its configured security policy. In
preparation for adding analagous support in the LSM for set*gid()
syscalls, we add the requisite hook here. Tested by putting print
statements in the security_task_fix_setgid hook and seeing them get hit
during kernel boot.

55e20bd12a Revert "btrfs: switch to iomap_dio_rw() for dio"
This reverts commit a43a67a2d7.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.

The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.

Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.

There have been discussions how to fix that, but revert seems to be the
least intrusive option.

bc139119a1 net: ethernet: ti: ale: fix allmulti for nu type ale
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.

This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f644727 ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").

Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
