There are now only two sparse warning left in mm/ (for sparc32) Both warnings relates to the return value of of_ioremap() which is __iomem.

iommu.c:69:21: warning: incorrect type in assignment (different address spaces)

    iommu->regs is set to a value obtained by of_ioremap().
    And this value is later dereferenced like this:
    iommu->regs->control = xxx;

io-unit.c:56:13: warning: incorrect type in assignment (different address spaces)
iounit->page_table is set to a value obtained by of_ioremap(), the address of the External Page Table.
And this value is dereference later like this dev->archdata.iommu->page_table[scan]

When looking closer at ioport.c which implments of_ioremap() I tentatively conclude that the direct reference above is OK. But as I was not sure I left these as is.

The warnings could have been silenced with a few casts but that would just hide the potential error that they flag.
