[PATCH 00/29] sparse warning fixes in arch/sparc/

[PATCH 00/29] sparse warning fixes in arch/sparc/

[Sam Ravnborg]

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.

Looks good, series applied, thanks a lot Sam.
