5da444aae5 sparc: fix format string argument for prom_printf()
prom_printf() takes printf style arguments.  Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().

This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

5d83d66635 sparc32: Move cache and TLB flushes over to method ops.
This eliminated most of the remaining users of btfixup.

There are some complications because of the special cases we
have for sun4d, leon, and some flavors of viking.

It was found that there are no cases where a flush_page_for_dma
method was not hooked up to something, so the "noflush" iommu
methods were removed.

Add some documentation to the viking_sun4d_smp_ops to describe exactly
the hardware bug which causes us to need special TLB flushing on
sun4d.

d894d964ff sparc32: Convert mmu_* interfaces from btfixup to method ops.
This set of changes displays one major danger of btfixup, interface
signatures are not always type checked fully.  As seen here the iounit
variant of the map_dma_area routine had an incorrect type for one of
it's arguments.

It turns out to be harmless in this case, but just imagine trying to
debug something involving this kind of problem.  No thanks.

679bea5e43 sparc: Kill mmu_{un,}lockarea().
These were used on sun4c during floppy data transfers since on that
chip we had to lock the cpu mappings into the TLB because we cannot
take a TLB miss during the assembler floppy interrupt handler that
does the data transfer.

That is no longer necessary since we've removed sun4c support, thus
this stuff can disappear completely.

aa83a26a19 sparc: use sparc64 version of scatterlist.h
Use sparc64 version of scatterlist.h.

There are three main differences:
    dma_addr_t replaces __u32
    dma_address replaces dvma_address
    dma_length replaces dvma_length

dma_addr_t is a u32 on sparc32.

Boot tested on sparc32.

e003934876 sparc32: Make IOMMU and IO-UNIT init work with device nodes.
And stick the iommu archdata pointer into the generic OF device tree
of_device struct as well.

We still have to pass the sbus_bus object down into the routines so
that the SBUS bus objects get the iommu cookies set properly.  After
drivers get converted to being pure OF drivers, that can go away.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
