The cats_map_irq() function in the Simtec CATS support
code is mapping IRQ 255 (invalid IRQ) into what is a
supposedly valid interrupt numner which can cause problems
with other devices then seeing an interrupt they cannot
claim.
If the IRQ number if >= 255, then return -1 as this is not
something we can map.

The existing code tries to get the pmd for the temporary page table
by doing:
pgd = pgd_alloc(&init_mm);
pmd = pmd_offset(pgd, PHYS_OFFSET);
Since we have a two level page table, pmd_offset() is a no-op, so
this just has a casting effect from a pgd to a pmd - the address
argument is unused. So this can't work.
Normally, we'd do:
pgd = pgd_offset(&init_mm, PHYS_OFFSET);
...
pmd = pmd_offset(pgd, PHYS_OFFSET);
to get the pmd you want. However, pgd_offset() takes the mm_struct,
not the (unattached) pgd we just allocated. So, instead use:
pgd = pgd_alloc(&init_mm);
pmd = pmd_offset(pgd + pgd_index(PHYS_OFFSET), PHYS_OFFSET);

Due to the problem of reset status bits being handled by different
registers between pxa2xx and pxa3xx, introduce a global reset_status
variable, initialized by SoC-specific code and later being used by
other drivers.
And also introduce clear_reset_status(), which is used to clear the
corresponding status bits. Pass RESET_STATUS_ALL to clear all bits.

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: David 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.

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.
