When encountering any vma in the range with policy other than MPOL_BIND or

the policy just allocated with mpol_dup().

This allows arbitrary users to leak kernel memory.

Since 6.1 we have noticed random rpm install failures that were tracked to
mremap() returning -ENOMEM and to commit ca3d76b0 ("mm: add merging
after mremap resize").

The problem occurs when mremap() expands a VMA in place, but using an
starting address that's not vma->vm_start, but somewhere in the middle. 
The extension_pgoff calculation introduced by the commit is wrong in that
case, so vma_merge() fails due to pgoffs not being compatible.  Fix the
calculation.

By the way it seems that the situations, where rpm now expands a vma from
the middle, were made possible also due to that commit, thanks to the
improved vma merging.  Yet it should work just fine, except for the buggy
calculation.

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

Adjust some MADV_XXX constants to be in sync what their values are on
all other platforms. There is currently no reason to have an own
numbering on parisc, but it requires workarounds in many userspace
sources (e.g. glibc, qemu, ...) - which are often forgotten and thus
introduce bugs and different behaviour on parisc.

A wrapper avoids an ABI breakage for existing userspace applications by
translating any old values to the new ones, so this change allows us to
move over all programs to the new ABI over time.
