All of the xcall delivery implementation is cpumask agnostic, so
we can pass around pointers to const cpumask_t objects everywhere.

The sad remaining case is the argument to arch_send_call_function_ipi().

It can eat up a lot of stack space when NR_CPUS is large.
We retain some of it's functionality by reporting at least one

Then modify all of the xcall dispatch implementations get passed and
use this information.

Now all of the xcall dispatch implementations do not need to be mindful

Ideally this could be simplified further such that we could pass
the pointer down directly into the xcall_deliver() implementation.

But if we do that we need to do the "cpu_online(cpu)" and
"cpu != self" checks down in those functions.
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We know the cpu is online and not the current cpu here.
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

For these cases the callers make sure:

1) The cpus indicated are online.

2) The current cpu is not in the list of indicated cpus.

Therefore we can pass a pointer to the mask directly.

One of the motivations in this transformation is to make use of
"&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant
data in the kernel and thus takes up no stack space.

Hopefully someone in the future will change the interface of
arch_send_call_function_ipi() such that it passes a const cpumask_t
pointer so that this will optimize ever further.

This patch changes the generic_defconfig so it works on all sn2
platforms I have access to.  There is only one support configuration
which was not tested and that configuration is only a combination of two
tested configurations.  With this patchset applied, a generic kernel can
be booted on either a RHEL 5.2, RHEL5.3, or SLES10 SP1 root and operate.
All features needed by SGI's ProPack are also working.  I have not
tested all features of RHEL or SLES, but they do at least boot.

Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h

This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h),
but, I'd like to add sh2a specific file here, because
1. the values defined there are not suitable for sh2a.
2. I don't think there is "common" definition for these values.

Values are chosen by consideration of followings...
 P1 is 0. perhaps no question.
 P2 is from hardware manual, which says no-cache area starts at 20000000.
 It means that P? space size=20000000.
 P3 is P2+size since asm/ptrace.h uses P3 as a end of P2.
 P4 is P3+size since asm/fixup.h uses P4 as a end of P3.
