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 7671fa22af sparc32: always register a PROM based early console
Do not require user to add "-p" to boot arguments to see
early info printed to prom console.

This is similar to the sparc64 functionality - which was added with:
3c62a2d347 ("[SPARC64]: Always register
a PROM based early console.")

Sam Ravnborg 9c2853af1f sparc32: probe for cpu info only during startup
We did a cpu_probe() call each time a CPU got online - which
only effect was to save latest CPU/FPU info for use by show_cpuinfo().
Use same setup as for sparc64 where we probe for this info during startup,
and only once.

This allowed us to annotate a few functions __init which again
fixed the following section mismatch warnings:

WARNING: vmlinux.o(.text+0x65f0): Section mismatch in reference from the function set_cpu_and_fpu() to the (unknown reference) .init.rodata:(unknown)
WARNING: vmlinux.o(.text+0x65f8): Section mismatch in reference from the function set_cpu_and_fpu() to the (unknown reference) .init.rodata:(unknown)
WARNING: vmlinux.o(.text+0x664c): Section mismatch in reference from the function set_cpu_and_fpu() to the variable .init.rodata:manufacturer_info

Andres Salomon 8d1255627d of/sparc: convert various prom_* functions to use phandle
Rather than passing around ints everywhere, use the
phandle type where appropriate for the various functions
that talk to the PROM.

Grant Likely 6016a363f6 of: unify phandle name in struct device_node
In struct device_node, the phandle is named 'linux_phandle' for PowerPC
and MicroBlaze, and 'node' for SPARC.  There is no good reason for the
difference, it is just an artifact of the code diverging over a couple
of years.  This patch renames both to simply .phandle.

Note: the .node also existed in PowerPC/MicroBlaze, but the only user
seems to be arch/powerpc/platforms/powermac/pfunc_core.c.  It doesn't
look like the assignment between .linux_phandle and .node is
significantly different enough to warrant the separate code paths
unless ibm,phandle properties actually appear in Apple device trees.

I think it is safe to eliminate the old .node property and use
phandle everywhere.

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!
