This just facilitates the next changeset where we'll be building
the cpu list and mondo block in this helper function.

The idea is that we'll use this cpu list array and mondo block
even for non-hypervisor platforms.

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.

We know the cpu is online and not the current cpu here.

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.

Now that SH has switched to vmalloc_exec() for PAGE_KERNEL_EXEC usage,

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.

SH never really supported a.out, so this was all just copied over blindly

Brian Wang reported that a FUSE filesystem exported through NFS could
return I/O errors on read. This was traced to splice_direct_to_actor()
returning a short or zero count when racing with page invalidation.
However this is not FUSE or NFSD specific, other filesystems (notably
NFS) also call invalidate_inode_pages2() to purge stale data from the
cache.
If this happens while such pages are sitting in a pipe buffer, then
splice(2) from the pipe can return zero, and read(2) from the pipe can
return ENODATA.
The zero return is especially bad, since it implies end-of-file or
disconnected pipe/socket, and is documented as such for splice. But
returning an error for read() is also nasty, when in fact there was no
error (data becoming stale is not an error).
The same problems can be triggered by "hole punching" with
madvise(MADV_REMOVE).
Fix this by not clearing the PG_uptodate flag on truncation and
invalidation.
