Re: [PATCH v1 00/10] KVM: arm64: Nested stage-2 walk error handling and other small fixes

retiring with the fault in PAR_EL1. Reporting the unreadable descriptor
as a Data Abort instead, for the stage-1 walks too, is a separate
change I'll send later.

Why later?

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.

My definition of a series is "an ordered set of changes that have a
common theme or form a progression towards a precise goal". This is
not a series, but a patch dump.

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 :)
