Bug Description
Currently there is no support for Arm support using kvm-ok. Currently when I run kvm-ok I get the following output:
INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used
[FFe]
We have ARM KVM support in the kernel, and now expect real A-15 server hardware to ship during the 13.10 cycle. So I think this bug has changed from hypothetical to real now. The patch is relatively small.
Testing: see MP for Brendan's results.
I suggest that we thoroughly test for regressions on the Intel side of things before uploading. We aren't changing Intel behaviour at all here - just trivially adding new code paths for ARM. I don't see how we can cause a regression for ARM here, ARM KVM support is new so it didn't work previously anyway.

I've just uploaded a distro patch to ppa:racb/ experimental for testing. In particular, I'm concerned to make sure that this doesn't accidentally break Intel. For Saucy I think we'll need an FFe whether it gets merged upstream or not, so I guess we need to test anyway.
Kees or Dustin: if it's not worth or we don't get this merged upstream and a new release soon, any objections to a distro patch in the meantime? Now that we finally have A-15s around and our kernel supports ARM KVM, it'd be great to get this in before release so all our tooling works.
