[PULL 00/28] target-arm queue

[Peter Maydell <peter.maydell@linaro.org>]

Hi; here's an arm pullreq. There's a combination of small stuff, plus
the hvf patchset that adds vGIC and nested-virt support. Last time we
tried to land this we got tripped up by some gitlab CI failures on jobs
that only run on the main staging CI run, not on the "run CI in your own
repo before sending" CI. Hopefully that won't happen again, but it's
possible...

thanks
