[PATCH 00/23] maintainer updates for 9.0 pre-PR (tests, plugin register support)

["Alex Bennée" <alex.bennee@linaro.org>]

The test patch is a simple house keeping one to clean up some
inadvertent GPLv3 tagging to GPLv2-or-later.

The main bulk of this series is register reading support for TCG
plugins. The main change to the API is that the get/read_register
functions are now implicitly vCPU context only so have dropped the
vcpu index parameter and use current_cpu instead. This avoids the need
for locking the gdbstub structures in case there is a cross-vCPU
access.

I've pulled in some patches from Pierrick's inline enhancement series
that allow this to happen (making sure the init callback is in the
vCPU context).

The following still need review:

  contrib/plugins: extend execlog to track register changes
  gdbstub: expose api to find registers

But I'd like to get this merged soon so its not a mad rush before soft
freeze and so we can get the new inline support stabilised and merged.

Alex.
