cc46bb98c0 [POWERPC] Add udbg support for RTAS console
Add udbg hooks for the RTAS console, based on the RTAS put-term-char
and get-term-char calls. Along with my previous patches, this should
enable debugging as soon as early_init_dt_scan_rtas() is called.

485a2d54db [PATCH] powerpc: Make early debugging options behave with oldconfig
If you undefine all the early debugging options and then run make oldconfig,
you don't get prompted to see if you want to enable any of them. This is
annoying.

AFAICT we can't do this just with a choice, because the choice is either
optional, in which case we don't get prompted, or not in which case we _must_
select early debugging.

So add a bool which controls whether we have early debugging at all, and then
if that's enabled provide the choice. The extra bool will actually be useful
in another patch I have lying around, so this is a win-win.

78af90629c powerpc: remove OCP references
OCP isn't used in arch/powerpc and hopefully will never be.

296167ae17 [PATCH] powerpc: Make early debugging configurable via Kconfig
This patch adds Kconfig entries to control the early debugging options,
currently in setup_64.c.

Doing this via Kconfig rather than #defines means you can have one source tree,
which is buildable for multiple platforms - and you can enable the correct
early debug option for each platform via .config.

I made udbg_early_init() a static inline because otherwise GCC is to daft to
optimise it away when debugging is off.

Now that we have udbg_init_rtas() we can make call_rtas_display_status* static.

cd6b0762a0 [PATCH] Move Kprobes and Oprofile to "Instrumentation Support" menu
Andrew Morton suggested to move kprobes from kernel hacking menu, since
kernel hacking menu is in-appropriate for the Kprobes.  This patch moves
Kprobes and Oprofile under instrumentation menu.

(akpm: it's not a natural fit, but things like djprobes and the s390 guys'
statistics library need a home)

eeb2d21806 powerpc: make iSeries boot
Now that we use the device tree, it helps to build it in.
It helps to links the kernel at the correct address.

14cf11af6c powerpc: Merge enough to start building in arch/powerpc.
This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.
