[PATCH 8/8] perf kvm: Fix building perf kvm on non x86 arches

[Arnaldo Carvalho de Melo]

From: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com>

Now, 'perf kvm stat' is only supported on x86, let its code depend on
(__x86_64__ || __i386__) to fix building it on other architectures.

I probably sound like a broken record at this point, but I've not seen
this go into any tip branch, nor is it in Linus' tree.  Hopefully this
gets pulled before 3.7 is released.

Pulled, thanks a lot Arnaldo!

I'll get this to Linus ASAP.

Note: got a conflict with perf/core in tools/perf/Makefile, when 
merging in tip:master. It appeared to me that perf/core already 
included all the changes to BASIC_CFLAGS that perf/urgent 
updated, so I picked the perf/core version.

The merged result seems to work fine but please double check it 
nevertheless.

Thanks,

	Ingo
