Platforms that are using GENERIC_BUG must call in to
module_bug_finalize()/module_bug_cleanup() in order to scan modules with
their own __bug_table sections that are otherwise unaccounted.

* 'for-linus' of git://git390.osdl.marist.edu/pub/scm/linux-2.6:
[S390] move include/asm-s390 to arch/s390/include/asm

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
of the cpu's which are seen in error state.

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
of details such as "is current cpu in the list?" and "is cpu online?"

The idea is that we'll use this cpu list array and mondo block

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.
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.

SH never really supported a.out, so this was all just copied over blindly
from x86 way back when. As we don't reference linux/a.out.h anywhere in
