Xen 4.17 release: Current status before the feature freeze

[Henry Wang <Henry.Wang@xxxxxxx>]

Hi all,

As the feature freeze date is around the corner (Sep. 9, 2022) and we are
currently summarizing the series for the release, here are the list of series
pending in the mailing list. Please add the ones that I probably missed.
Thank you very much!

Note that the blocker, automation, Arm lists should be accurate for tracking
the 4.17 release IMHO. More inputs and clarifications might needed to clarify
if all series in x86, tools and common lists are going to the Xen 4.17 release.

Also, as agreed from the September community call, the tracking of Xen 4.17
release will happen both in the mailing list and the Gitlab. I will send the 
Gitlab
link once the work is done. Thanks!

** Blocker List **:
1. Patch: x86: enable interrupts around dump_execstate()
https://patchwork.kernel.org/project/xen-devel/patch/e717897f-980d-ad44-31d9-39f5e7e1c45e@xxxxxxxx/
Status: Waiting for review.

2. The fix of libvirt after the virtio support in toolstack
Status: The OSSTEST seems to work properly, apart from what Jan
asked in IRC - the qemu and omvf OSSTEST might need a force push.
(I am not sure if this has been fixed so I just carried this)

kernel mode
