The loop fix is small and stops the hang. The Data Abort change
replaces the SEA-in-PAR_EL1 reporting at the four walk sites in at.c
and nested.c and has to stop the PC advancing past the AT. I haven't
done it yet, and I didn't want to hold the hang fix for it.

Sorry about that. When you asked me a couple of weeks ago to group
related patches rather than post them one at a time, I took it past
"related" and put everything small I had into one series.

I'll split it. The nested AT walk fixes with their selftest as one
series, with the Data Abort change in it if you'd rather have them
together, the SMCCC filter WARN on its own with Oliver's change, the
three documentation fixes as one series, and the two selftest leaks as
one.

Sorry again :)
