Hi!
What is going on here?
commit 5bdf3437603d4af87f9c7f424b0c8aeed2420745 upstream.
Upstream commit 5bdf is very different from this. In particular,
arch/arm64/kvm/hyp/smccc_wa.S | 66 +++++++++++++++++++++++++++++++++++++++
I can't find smccc_wa.S, neither in mainline, nor in -next. And it looks buggy. I suspect loop_k24 should loop 24 times, but it does 8 loops AFAICT. Same problem with loop_k32.
The kvm portion of these patches is the "trickiest" portions. I'll let James explain them, as he did so to me when sending the backports.
thanks,
