MIPS: SMP: Remove plat_smp_ops cpus_done method.
Nothing was using the method and there isn't any need for this hook. This
leaves smp_cpus_done() empty for the moment.
As suggested by Paul Bolle <pebolle@tiscali.nl>.

MIPS: Fix warning when including smp-ops.h with CONFIG_SMP=n
The gic_send_ipi_mask function declared in smp-ops.h takes a struct
cpumask argument, but linux/cpumask.h is only included within an #ifdef
CONFIG_SMP. Move the gic_ function declarations within that #ifdef too
to fix warnings during build such as:
In file included from arch/mips/fw/arc/init.c:15:0:

MIPS: Coherent Processing System SMP implementation
This patch introduces a new SMP implementation for systems implementing
the MIPS Coherent Processing System architecture. The kernel will make
use of the Coherence Manager, Cluster Power Controller & Global
Interrupt Controller in order to detect, bring up & make use of other
cores in the system. SMTC is not supported, so only a single TC per VPE
in the system is used. That is, this option enables an SMVP style setup
but across multiple cores.

MIPS: Move GIC IPI functions out of smp-cmp.c
The GIC IPI functions aren't necessarily specific to the "CMP
framework" SMP implementation, and will be used elsewhere in a
subsequent commit. This patch adds cleaned up GIC IPI functions to a
separate file which is compiled when a new CONFIG_MIPS_GIC_IPI Kconfig
symbol is selected, and selects that symbol for CONFIG_MIPS_CMP.

MIPS: Malta: Fix crash in SMP kernel on non-CMP systems.
Since 6be63bbbdab66b9185dc6f67c8b1bacb6f37f946 (lmo) rsp.
af3a1f6f4813907e143f87030cde67a9971db533 (kernel.org) the Malta code does
no longer probe for presence of GCMP if CMP is not configured. This means
that the variable gcmp_present well be left at its default value of -1
which normally is meant to indicate that GCMP has not yet been mmapped.
This non-zero value is now interpreted as GCMP being present resulting
in a write attempt to a GCMP register resulting in a crash.
Reported and a build fix on top of my fix by Rob Landley <rob@landley.net>.

cpumask: arch_send_call_function_ipi_mask: mips
We're weaning the core code off handing cpumask's around on-stack.
This introduces arch_send_call_function_ipi_mask(), and by defining
it, the old arch_send_call_function_ipi is defined by the core code.
We also take the chance to wean the implementations off the
obsolescent for_each_cpu_mask(): making send_ipi_mask take the pointer
seemed the most natural way to ensure all implementations used
for_each_cpu.

MIPS: Add arch generic CPU hotplug
Each platform has to add support for CPU hotplugging itself by providing
suitable definitions for the cpu_disable and cpu_die of the smp_ops
methods and setting SYS_SUPPORTS_HOTPLUG_CPU. A platform should only set
SYS_SUPPORTS_HOTPLUG_CPU once all it's smp_ops definitions have the
necessary changes. This patch contains the changes to the dummy smp_ops
definition for uni-processor systems.
