I noticed that you you haven't provided a rebase to the ck-hrtimer patches since 5.15.y. Any plans to add them back or have you dropped them totally?

I tried applying them to 5.17.1 from the 5.15.y-* directory but the last patch in the series fails. I attempted to rebase them here. What do you think? The only one that required manual rebasing was 0008-clockevents-hrtimer-Make-hrtimer-granularity-and-min.patch so please verify that I did it correctly.

When I tried compiling it, a failure occurred:

It could be desired tl upstream some of the changed made here to the stock kernel. Maybe it was already tried fot some.

I think we can also use this thread to list statuses and infos on upstreamibg changes.
(And maybe dont close this, cause this can always be desired and we dont need duplicated of this issue)

I'm getting this error when applying the patch:

error: patch failed: include/net/tcp.h:723
error: include/net/tcp.h: patch does not apply
Patch failed at 0015 tcp: introduce per-route feature RTAX_FEATURE_ECN_LOW

(works fine in 6.8, but I want to use 6.6)

For kernel 5.15.50 one of the amd-pstate patches does not apply:

This happens when I try to apply this patch to linux-lts source from the Arch Linux.

I find the line

for_each_present_cpu(cpu) {

already in the initial kernel source. Is this patch obsolete for any new 5.15 kernel?
