Merge tag 'microblaze-v5.11' of git://git.monstr.eu/linux-2.6-microblaze

Pull microblaze updates from Michal Simek:
 "The biggest change is to remove support for noMMU configuration.

  FPGAs are bigger so people use Microblaze with MMU for a lot of years
  and there is likely no user of this code anymore. No one is updating
  libraries for this configuration either.

   - Remove noMMU support

   - Add support for TIF_NOTIFY_SIGNAL

   - Small header fix"
