And we can certainly get rid of the const function attributes, there
is no way that's needed any longer and no other arch uses this kind
of annotation here.

That lets us also get rid of the run-time initialization of
protection_map[] and all the ugly module workarounds for
PAGE_KERNEL and PAGE_SHARED to deal with the fact that we
can't do btfixups for modular code.

Also we can remove BTFIXUPCALL_SWAPO0G0 as that is no longer
used.

This was rather amusing, we were setting the btfixup vectors
based upon cpu type but all to the same exact generic srmmu
routines.

Furthermore, we were inconsistently marking the fixup as
either BTFIXUPCALL_SWAPO0G0 or BTFIXUPCALL_NORM.

What a mess, glad we could untangle this stuff.

It is a noop for srmmu - so use a define as sparc64 does.
And drop all sparc callers - no need to confuse our-self
be calling a noop function.

This revealed that the implementation of switch_mm

No harm as said argument was never used - but confusing.

Fix following warning:
arch/sparc/include/asm/floppy_32.h:342:5: warning: 'op' may be used uninitialized in this function

The warning are legitimite and we can end up using op uninitialized.
This fixes build with my gcc on UP.

We already sorted out if we are a sun4/sun4c and halted.
So no need to check the prom version as we know this is
a v2 or v3 as sun4m, sun4d etc. does not use a v1 prom.

I left some around, like the ones in the openprom headers, since

All the remaining references are trivially removed since we've

assembler code in commit b7d96ce1

Since we no longer test the cpu model value, no need to load
it into a register any more.

It just gets overwritten in the next instruction anyways. :-)
