Merge tag 'm68knommu-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu

Pull m68knommu updates from Greg Ungerer:
 "Only two changes.

  One removes the now unused CONFIG_MCPU32 symbol. The other sets a
  default for the CONFIG_MEMORY_RESERVE config symbol (this aids
  scripting and other automation) so you don't interactively get asked
  for a value at configure time.

  Summary:

   - remove unused CONFIG_MCPU32 symbol

   - default CONFIG_MEMORY_RESERVE value (for scripting)"
