4696b64d23 sparc: Fix minor SPARC32 compile error
When CONFIG_PROC_FS is unset, include/linux/interrupt.h defines
init_irq_proc() as an empty function.

arch/sparc/kernel/irq_32.c defines this function unconditionally.

Fix the latter so that it only defines this function when CONFIG_PROC_FS
is set.

This fixes the following error:
arch/sparc/kernel/irq_32.c:672: error: redefinition of 'init_irq_proc'
include/linux/interrupt.h:461: error: previous definition of
'init_irq_proc' was here

This was found using randconfig builds.

47cd5265ea sparc: Clean arch-specific code in prom_common.c
prom_nextprop() and prom_firstprop() have slightly different calling
conventions in 32 and 64 bit SPARC.

prom_common.c uses a ifdef guard to ensure that these functions are
called correctly.

Adjust code to eliminate this ifdef by using a calling convention that
is compatible with both 32 and 64 bit SPARC.

761b602620 sparc: Use 64BIT config entry
Use 64BIT config entry to distinguish between 32 and 64bit builds
instead of relying on the ARCH setting.  Using sparc64 as ARCH still
forces 64BIT on.

Inspired by the x86 and s390 configs.

7c59d28d0e sparc: unify openprom.h
After the preparational steps the unification was simple.

The linux_prom_pci_registers definition did not look like
it could be unified at first look since the structure is assigned
using prop_getproperty() / of_get_property() so the structure
is assumed to come direct form the prom.

The LINUX_OPPROM_MAGIC was kept even if it is not used by the kernel
on the assumption that userspace may require it.

f3ec38d513 sparc: unify ptrace.h
The two ptrace.h implementations are very alike but
the small differences required two set of ifdef/else/endif pairs.

The definition of reg_window32 could have been shared but
that would have required several updates in sparc32 code as
all printk formatting for example assume it is longs.

sparc_stackf looked like anohter candidate to share if the 32
bit was renamed to sparc_stackf32.
But it contains two pointers in the sparc32 version which would
have been 64 bit in the sparc64 version so it was non-trivial.
Using a set of accessor macros could do the trick if pursued later.

The sparc64 specific definitions are not protected by
ifdef - as it should not be required to do so.

They were almost identical and with the preapration
patch nothing was needed to be added.

The unified version contains a few sparc64 only definitions
but they are kept as is and not protected by ifdef/endif.
The unified version exports a bit more to userspace then the
32 bit version did.

fe6875ec5c sparc: introduce CONFIG_BITS
CONFIG_BITS is set to 32 for sparc32
and 64 for sparc64.

This allow us to use this symbol in for example header files
to ease unification of sparc32 and sparc64.

878a553595 sparc: We need to implement arch_ptrace_stop().
In order to always provide fully synchronized state to the debugger,
we might need to do a synchronize_user_stack().

A pair of hooks, arch_ptrace_stop_needed() and arch_ptrace_stop(),
exist to handle this kind of situation.  It was created for
the sake of IA64.

Use them, to flush the kernel side cached register windows
to the user stack, when necessary.

98a79d6a50 cpumask: centralize cpu_online_map and cpu_possible_map
Impact: cleanup

Each SMP arch defines these themselves.  Move them to a central
location.

Twists:
1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
   CONFIG_INIT_ALL_POSSIBLE for this rather than break them.

2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
   Those archs simply have phys_cpu_present_map replaced everywhere.

3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
   so I just manipulate them both in sync.

4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
   declarations.
