[GIT PULL] arm-soc: Xilinx zynq core - smp for v3.10

[Michal Simek]

Hi Arnd and Olof,

please pull the following smp support to your arm-soc tree.

This branch is based on zynq/clksrc/cleanup parts because
there are some dependencies on moving timer to generic location.

I could based it on standard Linux tagged version but you will get
several conflicts you will have to resolve.
If you are OK to resolving these problems, please let me know
I will create another branch with core-smp changes which are not based
on zynq/clksrc/cleanup branch.

Thanks,
Michal

This one gave me a little trouble because of conflicts with Catalin's
gic/cleanup branch. Could both of you (Michal and Catalin) have a look
at my resolution? I basically just removed the zynq_secondary_init()
function added in this branch.

I've merged it all into next/soc2 and added a merge with gic/cleanup
to resolve the conflict.

Also, please use signed tags for sending pull requests and include
a description of the branch contents that will end up in the merge
commit.

You might want to resolve this new warning:

arch/arm/mach-zynq/hotplug.c:1:0: warning: switch -mcpu=cortex-a9 conflicts with -march= switch

found by lastnights OMAP4430 randconfig build.

Do you have that randconfig file?
And can you please point me to the repo which is is used for this build?

Thanks,
Michal

Everything which is public is at:

http://www.home.arm.linux.org.uk/developer/build/

I don't make the build tree available because it changes too often and
I don't want _anyone_ to make the mistake of assuming that anything
which is in there is stable.  However, the above URL tells you how it's
generated.  As it is mainline+arm-soc+my tree (including some bits I'm
not publishing), it's pretty much publically available anyway.

Err, drop the .home bit out of that.

Thanks that's everything what I need.

I have looked at it. (I downloaded .config last week to have).
I have tried gcc 4.6.3 from kernel.org
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/
and also (Sourcery CodeBench Lite 2011.09-50) 4.6.1 toolchain
but I can't see this warning.

Which gcc version do you use?

Thanks,
Michal
