- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps

coresight: Remove pending trace ID release mechanism

Pending the release of IDs was a way of managing concurrent sysfs and
Perf sessions in a single global ID map. Perf may have finished while
sysfs hadn't, and Perf shouldn't release the IDs in use by sysfs and
vice versa.

Now that Perf uses its own exclusive ID maps, pending release doesn't
result in any different behavior than just releasing all IDs when the
last Perf session finishes. As part of the per-sink trace ID change, we
would have still had to make the pending mechanism work on a per-sink
basis, due to the overlapping ID allocations, so instead of making that
more complicated, just remove it.

coresight: Expose map arguments in trace ID API

The trace ID API is currently hard coded to always use the global map.
Add public versions that allow the map to be passed in so that Perf
mode can use per-sink maps. Keep the non-map versions so that sysfs
mode can continue to use the default global map.

System ID functions are unchanged because they will always use the
default map.

coresight: trace-id: Add API to dynamically assign Trace ID values

The existing mechanism to assign Trace ID values to sources is limited
and does not scale for larger multicore / multi trace source systems.

The API introduces functions that reserve IDs based on availabilty
represented by a coresight_trace_id_map structure. This records the
used and free IDs in a bitmap.

CPU bound sources such as ETMs use the coresight_trace_id_get_cpu_id
coresight_trace_id_put_cpu_id pair of functions. The API will record
the ID associated with the CPU. This ensures that the same ID will be
re-used while perf events are active on the CPU. The put_cpu_id function
will pend release of the ID until all perf cs_etm sessions are complete.

For backward compatibility the functions will attempt to use the same
CPU IDs as the legacy system would have used if these are still available.

Non-cpu sources, such as the STM can use coresight_trace_id_get_system_id /
coresight_trace_id_put_system_id.
