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. Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] DEBUG_PAGEALLOC for 64-bit Here's an implementation of DEBUG_PAGEALLOC for 64 bits powerpc. It applies on top of the 32 bits patch. Unlike Anton's previous attempt, I'm not using updatepp. I'm removing the hash entries from the bolted mapping (using a map in RAM of all the slots). Expensive but it doesn't really matter, does it ? :-) Memory hot-added doesn't benefit from this unless it's added at an address that is below end_of_DRAM() as calculated at boot time.

[POWERPC] Make xmon disassembly optional While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

[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.

[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.
