powerpc: Move most of setup.h out of uapi Most of setup.h should not be exported to userspace, so move it back. All we are left with is the asm-generic include to pick up the COMMAND_LINE_SIZE define.

powerpc: Move local setup.h declarations to arch includes Move the few declarations from arch/powerpc/kernel/setup.h into arch/powerpc/include/asm/setup.h. This resolves a sparse warning for arch/powerpc/mm/numa.c which defines do_init_bootmem() but can't include the setup.h header in the prior path. Resolves: arch/powerpc/mm/numa.c:998:13: warning: symbol 'do_init_bootmem' was not declared. Should it be static?

powerpc: Remove bootmem allocator At the moment we transition from the memblock alloctor to the bootmem allocator. Gitting rid of the bootmem allocator removes a bunch of complicated code (most of which I owe the dubious honour of being responsible for writing).

void setup_panic(void);
powerpc: Clean up panic_timeout usage Default CONFIG_PANIC_TIMEOUT to 180 seconds on powerpc. The pSeries continue to set the timeout to 10 seconds at run-time. Thus, there's a small window where we don't have the correct value on pSeries, but if this is only run-time discoverable we don't have a better option. In any case, if the user changes the default setting of 180 seconds, we honor that user setting.
