Subject: kvm_stat: Add powerpc support
X-Git-Tag: qemu-xen-4.6.0-rc1~102^2~7
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=4725398f9309d05936fec2eaaa6e97e01e25545e;p=qemu-upstream-4.6-testing.git

Add support for powerpc platforms. We use uname -m, which allows us to
detect ppc, ppc64 and ppc64le/el.
