Subject[PATCH 0/4 v3] smp_call_function_many issues from review
From
Date
Picking up this thread from the beginning of Feburary,  I updated
the comments in 3 and 4 based on Paul's review. I have inserted
my proposed alternative to Paul's additional patch as patch 2,
and tweaked the changelog on 1.

[PATCH 1/4 v3] call_function_many: fix list delete vs add race
[PATCH 2/4 v3] call_function_many: add missing ordering
[PATCH 3/4 v3] smp_call_function_many: handle concurrent clearing of mask
[PATCH 4/4 v3] smp_call_function_interrupt: use typedef and %pf

Peter Z acked a prior version of patch 1, and Mike Galbraith has
done some stress testing on the combinaton of 1,3,4, and Paul's patch.

The prior posting of this series is available here:
https://patchwork.kernel.org/patch/522021/
https://patchwork.kernel.org/patch/522031/
http://marc.info/?l=linux-kernel&m=129654439817236&w=2

And Paul's additional patch from review was here
https://patchwork.kernel.org/patch/525891/

Looking forward, I would suggest 1 and 2 are required for stable, 3 may
be suitable as it fixes races that otherwise requires cpumask copies
as in 75c1c91cb92806f960fcd6e53d2a0c21f343081c ([IA64] eliminate race
condition in smp_flush_tlb_mm). By contrast 4 is just comments except
for the %pS to %pf change.

Dimitri or Tony, let me know if you would like a revert patch for
75c1c91c to be added after patch 3.
