To allow using newer instructions that current assemblers don't know about,
replace the `at` instruction with the underlying SYS instruction.

Marc -- what would you like to do with this patch? I think the POE series
is really close now, so ideally I'd queue the lot on a branch in arm64
and you could pull the first ~10 patches into kvmarm if you need 'em.

Would what work for you, or did you have something else in mind (since
this one is also included in your series adding nv support for AT).

Is there any progress on this front? I am quite eager to queue the AT
series, but the dependency on this patch is preventing me to do so.

I can see there are outstanding questions on the POE series, so I was
wondering if we should consider reversing the dependency: I can create
a stable branch with this single patch, which you can pull as a prefix
of the POE series.

That sounds like a good idea. The uaccess discussion seems to have
stalled and I don't really want to merge the series without concluding
that.

So please go ahead with this single patch and I'll pull it in if things
start moving again.

Now pushed to [1].

Thanks,

	M.
