LSI decided to cancel this patch but wants the rest in.
Can I send you the pull request?

called with a function that doesn't return.

From: John Jacques john.jacq...@lsi.com
When we do a reset (core, not chip or system), the core that is doing
the reset has to tell all the other cores to reset. To do this, we call
smp_call_function_single().
In this case the function specified in smp_call_function_single() doesn't
return.
The wait parameter (third argument, described as '@wait: If true,
wait until function has completed on other CPUs.') doesn't work as described
without the patch.
Without the patch, smp_call_function_single() doesn't return when the
function indicated resets the called core. The comments indicate that it
should, but it does not.

Re: [linux-yocto] [PATCH 47/57] Basic perf support for axxia plaform block provided by LSI.
Bruce,
I am going to resubmit this group of patches less any patch that has to do with
RIO. This was requested by our customer. This should remove any patches that
don't have the required comments in the headers. The other patches are all
updated as per your comments.
Charlie

Hi,
The basic support includes:
* Generic AXXIA SMON (Statistic Monitor) functionality.
* Support for Memory Controllers:
- DDRC, DDR Controllers.
- ELM, Encryption Memory Controllers .
*Preparation for support of:
- PCX, integrated Ethernet switch.
- VP, virtual pipeline packet processing engines.
Documentation, VP/PCX support as well as patch alignment with coming ARM L3$
and interconnect is in the workings.
Looks good. Thanks for the summary.
Charlie: can we capture this in the log ?

Can we get a short feature listing of what is included in the basic support ?
A summary here is fine, and perhaps a README or other perf documentation
update as well.
