We have been using the kexec/kdump patches on ARM64 and would like to
use them from upstream.

Assuming these are not going to be in Linux-4.5, a rebased set on
Linux-4.5 would be very useful.

I'm waiting for one of two things to happen, either Marc Zyngier gives
an ack for the patch 'arm64: kvm: allows kvm cpu hotplug', or the arm64
maintainers decide they will accept my proposal to merge kexec with a
conditional in the Kconfig that only allows one of KVM or kexec to be
selected.

Depending on !KVM isn't even an option as far as I'm concerned. It basically
makes this all dead code.

As for awaiting an ack on the kvm hotplug patch, afaict, Akashi was going
to address James's comments on the last posting [1].

Come on!
I have already fixed this issue, but still waiting for Geoff rebasing his patch
as he is now a submitter of the whole patch series including kexec/kdump.
(Please note, as James suggested, some (minor) modification need be made for
rebasing onto v4.5)

The kexec patches have been in review for 20 months now, with only
minor changes in the past 15.  I don't expect much would be gained in
posting the kexec series again unless there is a chance they would be
merged.

Why do you say that? v13 attracted lots of comments from a variety of
reviewers, so the onus is on you to address that feedback and post a
new version. Alternatively, declare that you no longer to intend to work
on the series, and perhaps then somebody else can pick it up and finish
the job.

*If* Geoff is no longer willing to work on upstreaming kexec stuff,
I will probably take over his task.
