Jason Baron b71d47c14f 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.

Robert Jennings b88c4767d9 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?

I noticed a couple of function prototypes for functions that
no longer exist. Remove them.

Anton Blanchard 560285cd2c 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.

Suzuki Poulose a84fcd4687 powerpc: Change memory_limit from phys_addr_t to unsigned long long
There are some device-tree nodes, whose values are of type phys_addr_t.
The phys_addr_t is variable sized based on the CONFIG_PHSY_T_64BIT.

Change these to a fixed unsigned long long for consistency.

This patch does the change only for memory_limit.

The following is a list of such variables which need the change:

 1) kernel_end, crashk_size - in arch/powerpc/kernel/machine_kexec.c

 2) (struct resource *)crashk_res.start - We could export a local static
    variable from machine_kexec.c.

Changing the above values might break the kexec-tools. So, I will
fix kexec-tools first to handle the different sized values and then change
 the above.

Paul Gortmaker e5a6a1c909 powerpc: derive COMMAND_LINE_SIZE from asm-generic
The default COMMAND_LINE_SIZE in asm-generic is 512, so the
net effect of this change is nil, aside from the cleanup
factor.  See also commit 2b74b8569.

Stephen Rothwell b8b572e101 powerpc: Move include files to arch/powerpc/include/asm
from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
