Sam Ravnborg 306f123162 sparc32: remove sun4c traps
We used to runtime patch the trap table for srmmu.
With the removal of sun4c support this is no longer required.

With the sun4c trap removed we can remove all the referenced
trap handling which is sun4c specific.
This also allows us to get rid of the nosun4c.c file that
contained only dummy functions/data.

Sam Ravnborg 2c1cfb2db6 sparc32: drop sun4c support
Machines with sun4c support are very rare these days, and noone
is using them for any practical purposes.
The sun4c support has been know broken for quite some time too.

So rather than trying to keep it up-to-date, lets get rid of it.
This allows us to do some very welcome cleanup of sparc32 support.

Updated the former sun4c specifc nmi (which was also used
for sun4m UP) to be a generic UP NMI.

David S. Miller 3e37fd3153 sparc: Kill custom io_remap_pfn_range().
To handle the large physical addresses, just make a simple wrapper
around remap_pfn_range() like MIPS does.

Konrad Eisele 0fd7ef1fe0 sparc,leon: Introduce the sparc-leon CPU type.
Add sparc_leon enum, M_LEON|M_LEON3_SOC machine. Add compilation of
leon.c in mm and kernel
if CONFIG_SPARC_LEON is defined. Add sparc_leon dependent
initialization to switch statements + head.S.

Adrian Bunk 5110bd21b8 sparc: remove CONFIG_SUN4
While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.

And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

Linus Torvalds 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!
