At this stage only critical bugs (crashes during startup, security issues, serious memory leaks, etc). This patch looks like a nice documentation fix but it has a limited scope and I don't think it warrants rolling an -rc4 tag next week. Do you agree with deferring this patch until after the 8.2 release?

Applied, thanks. Please update the changelog at https://wiki.qemu.org/ChangeLog/8.2 for any user-visible changes.

I noticed the code blocks where not rendering properly so thought I'd better fix things up. So: - Use better title for the machine type - Explain why Xen is a little different - Add a proper anchor to the tpm-device link - add newline so code block properly renders - add some indentation to make continuation clearer Signed-off-by: Alex Bennée <alex.bennee@linaro.org> --- docs/specs/tpm.rst | 2 ++ docs/system/arm/xenpvh.rst | 39 +++++++++++++++++++++----------------- 2 files changed, 24 insertions(+), 17 deletions(-)
