      ====================
      sparc32: introduce asm-generic
      
      Inspired by Michal Simek <monstr@monstr.eu> this patch-set
      introduces asm-generic/io.h for sparc32.
      
      As the diff-stat tells this was a nice code-reduction.
      
      The changes are done on top of the previous sent sparse warning cleanup.
      But I do not expect any difficult conflicts if applied alone.
      
      leon_pci + pcic are touched because they had local
      and identical implementations of functiones that are
      static inline in asm-generic/io.h
      
      leon_pci_grpci1 + leon_pci_grpci2 are touched becuse they
      used a sparc spacific implmentation of swab32.
      They have just been changed to use the global variant.
      
      I also looked at sparc64 - but there were to many
      sparc64 assembler implementations of the io
      functons - and the generic io.h did not support this mix.
      
      The last patch kills a few defines in io.h for sbus.
      I assume they were introduced before the functions
      were all shifted over to __iomem style pointers.
      The same could be done for sparc64 - but then
      there were even more of the same so I left
      this for another time.
      
      The patch-set has been build tested only.
      My attempts to test this using qemu have failed as
      the qemu version I have errors out.
      And my fedora box are mssing some libs to build
      qemu from source :-(

      sparc32: clean up io_32.h · c3373da9
      Sam Ravnborg authored
      After introducing asm-generic/io.h a few things could still be cleaned up
      o Drop useless macro indirection for sbus_* io access methods
        They were in the past used to hide casts between long and pointers
        but this is no longer so
      o Fix function definitions for sbus memory functions so
        return value appear on same line as function name

      sparc32: introduce asm-generic/io.h · e1039fb4
      Sam Ravnborg authored
      Use asm-generic/io.h definitions where applicable.
      The inxx() and outxx() methods whcih was duplicated in pcic.c +
      leon_pci.c are replaced by a set of static inlins from asm-generic/io.h
      
      iomap.c is replaced by the generic versions, but are still
      present to support sparc64.

      ====================
      sparse warning fixes in arch/sparc/
      
      The following patch-set address a lot of sparse warnings
      in the sparc32 specific parts of arch/sparc/.
      A few sparc64 bits are touched too when code are shared.
      
      Within arch/sparc/mm/ only two warnings remains.
      These are related to the return value of of_ioremap() which is __iomem.
      
      Within arch/sparc/kernel/ only three files now produces sparse warnings:
          sys_sparc_32.c
          time_32.c
          auxio_32.c
      
      The fixes was not obvious so the warnings was left for now.
      
      When looking at tadpole.c I was left with the impression that most
      of the code was actually unused - but for now I added a "TODO".
      
      This is made on top of 3.15-rc2.
      
      This set replaces the two sets sent the last days.
      V2:
      - Do not add extern in front of prototypes.
      - Tidy up a few changelongs
      
      There are still sparse warnings left that are easy to address.
      But this fixes the majority.

      Add proper decalarations for the above.
      
      The leaves one sparse warning:
      auxio_32.c:130:33: warning: cast removes address space of expression
      
      This is here:
          auxio_power_register = (unsigned char *) of_ioremap()
      
      This is __iomem that is removed from return value of of_ioremap()
      The pointer is later used without any helpers in process_32.c:
          *auxio_power_register |= AUXIO_POWER_OFF;
      
      It would be simple to introduce a few sbus() helpers.
      But as I was not sure this was correct the warning are left as-is.
