[PATCH 0/10] Add generic helpers for arch IPI function calls #4

[Jens Axboe <jens.axboe@oracle.com>]

Hi,

Jeremy sent me a ping about this patchset, so here's an updated
version against the current kernel (2.6.26-rc4'ish). Changes since
last post:

- Incorporate Pauls changes and suggestions to make
  smp_call_function_single() both cleaner and (hopefull) deadlock free
  within the restrictions set.
- Fix various compile problems with some archs and .config configurations.

Not really a lot of churn, it's mostly solid and works well on the
archs that I test (x86, x86-64, ppc) and I know that it works well
on ia64 as well.

The nice diffstat is below, enjoy.
