Well, I don't really have a great solution for that, other than hoping
that 1/5 makes it into Linus' master at some point.
I see that it's a stretch, but pulling 1/5 into 5.11 now would
prepare the stage for the others to go via any tree, into 5.12-rc1?
Or you could maybe take both 1/5 and 5/5 into your kvm-arm tree, and
would hope that a git rebase later would sort this out for you?
But I think you are much more experienced in those kind of issues, so
happy to hear about any other solutions.
for-next/rng is a stable branch, so anybody who wants the first patch
can
just pull it (without anything I queue on top).
OK. I'll pull that branch and stash the KVM stuff on top.
Thanks,
M.
