Linus Torvalds 35f79d0e2c parisc architecture fixes for kernel v6.2-rc1:
Fixes:
 - Fix potential null-ptr-deref in start_task()
 - Fix kgdb console on serial port
 - Add missing FORCE prerequisites in Makefile
 - Drop PMD_SHIFT from calculation in pgtable.h
 
 Enhancements:
 - Implement a wrapper to align madvise() MADV_* constants with other
   architectures
 - If machine supports running MPE/XL, show the MPE model string
 
 Cleanups:
 - Drop duplicate kgdb console code
 - Indenting fixes in setup_cmdline()

Pull parisc updates from Helge Deller:
 "There is one noteable patch, which allows the parisc kernel to use the
  same MADV_xxx constants as the other architectures going forward. With
  that change only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on
  others) which is different. To prevent an ABI breakage, a wrapper is
  included which translates old MADV values to the new ones, so existing
  userspace isn't affected. Reason for that patch is, that some
  applications wrongly used the standard MADV_xxx values even on some
  non-x86 platforms and as such those programs failed to run correctly
  on parisc (examples are qemu-user, tor browser and boringssl).

  Then the kgdb console and the LED code received some fixes, and some
  0-day warnings are now gone. Finally, the very last compile warning
  which was visible during a kernel build is now fixed too (in the vDSO
  code).

  The majority of the patches are tagged for stable series and in
  summary this patchset is quite small and drops more code than it adds:

Fixes:
   - Fix potential null-ptr-deref in start_task()
   - Fix kgdb console on serial port
   - Add missing FORCE prerequisites in Makefile
   - Drop PMD_SHIFT from calculation in pgtable.h

  Enhancements:
   - Implement a wrapper to align madvise() MADV_* constants with other
     architectures
   - If machine supports running MPE/XL, show the MPE model string

  Cleanups:
   - Drop duplicate kgdb console code
   - Indenting fixes in setup_cmdline()"
