Merge tag 'unsigned-char-6.2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux

Pull unsigned-char conversion from Jason Donenfeld:
 "Enable -funsigned-char and fix code affected by that flag.

  During the 6.1 cycle, several patches already made it into the tree,
  which were for code that was already broken on at least one
  architecture, where the naked char had a different sign than the code
  author anticipated, or were part of some bug fix for an existing bug
  that this initiative unearthed.

  These 6.1-era fixes are:

    648060902a ("MIPS: pic32: treat port as signed integer")
    5c26159c97 ("ipvs: use explicitly signed chars")
    e6cb876945 ("wifi: airo: do not assign -1 to unsigned char")
    937ec9f7d5 ("staging: rtl8192e: remove bogus ssid character sign test")
    6770473832 ("misc: sgi-gru: use explicitly signed char")
    50895a55bc ("ALSA: rme9652: use explicitly signed char")
    ee03c0f200 ("ALSA: au88x0: use explicitly signed char")
    835bed1b83 ("fbdev: sisfb: use explicitly signed char")
    50f19697dd ("parisc: Use signed char for hardware path in pdc.h")
    66063033f7 ("wifi: rt2x00: use explicitly signed or unsigned types")

  Regarding patches in this pull:

   - There is one patch in this pull that should have made it to you
     during 6.1 ("media: stv0288: use explicitly signed char"), but the
     maintainer was MIA during the cycle, so it's in here instead.

   - Two patches fix single architecture code affected by unsigned char
     ("perf/x86: Make struct p4_event_bind::cntr signed array" and
     "sparc: sbus: treat CPU index as integer"), while one patch fixes
     an unused typedef, in case it's ever used in the future ("media:
     atomisp: make hive_int8 explictly signed").

   - Finally, there's the change to actually enable -funsigned-char
     ("kbuild: treat char as always unsigned") and then the removal of
     some no longer useful !__CHAR_UNSIGNED__ selftest code ("lib:
     assume char is unsigned").

  The various fixes were found with a combination of diffing objdump
  output, a large variety of Coccinelle scripts, and plain old grep. In
  the end, things didn't seem as bad as I feared they would. But of
  course, it's also possible I missed things.

  However, this has been in linux-next for basically an entire cycle
  now, so I'm not overly worried. I've also been daily driving this on
  my laptop for all of 6.1. Still, this series, and the ones sent for
  6.1 don't total in quantity to what I thought it'd be, so I will be on
  the lookout for breakage.

  We could receive a few reports that are quickly fixable. Hopefully we
  won't receive a barrage of reports that would result in a revert. And
  just maybe we won't receive any reports at all and nobody will even
  notice. Knock on wood"

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
