David S. Miller bd4352cadf sparc64: Fix bootup with mcount in some configs.
Functions invoked early when booting up a cpu can't use
tracing because mcount requires a valid 'current_thread_info()'
and TLB mappings to be setup.

The code path of sun4v_register_mondo_queues --> register_one_mondo
is one such case.  sun4v_register_mondo_queues already has the
necessary 'notrace' annotation, but register_one_mondo does not.

Normally register_one_mondo is inlined so the bug doesn't trigger,
but with some config/compiler combinations, it won't be so we
must properly mark it notrace.

While we're here, add 'notrace' annoations to prom_printf and
prom_halt so that early error handling won't have the same problem.

Robert Reif efe6c3dd8b sparc: Use sparc64 version of prom/printf.c
Use sparc64 version of prom/printf.c.

The only differences for sparc32 is that prom_printf is no longer
exported for modules which should be OK.

Sam Ravnborg 708d4f0964 sparc: prepare prom/ for unification
- rename files where sparc64 uses identical names to *_32.c
- refactor Makefile (but keep linking order)

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!
