It's too late, sorry. Last week might have been too late too, why the
last-minute pull request?
Please send new changes after -rc1 is out for bugfixes and for normal
new features.

Why rebase? What required that?
thanks,

Apologies, I was out sick last week. I was hoping that there would be
an rc8. The tree wasn't changed since last two weeks. I will try to
send the pull request at rc5-rc6 now onwards.

Just to make sure I understand this correctly,
- I can send a pull request with handpicked fixes for rc1
- What about the other new features ?
(I can summaries the features below)
- TRBE ACPI support ( Parts of this feature went into v6.6 via
Will's perf subsystem, the coresight part was dropped due to
a conflict. I queued it for v6.7 - 2patches)
- CoreSight TPDM support for DSB feature (~10patches)
- Support for configuring cycle count threshold for ETM (3 patches)
Do they need to wait for v6.8 or could some of them go in for v6.7 ?

This was to be on the safer side. I don't think there was any conflict.

Yes, after -rc1 is out.

They need to wait until 6.8-rc1, you can send me a pull request for them
after -rc1 is out as well, for my -next branch.

As Linus constantly says, NEVER rebase unless you have to. That just
makes history messy, and makes me think that something actually changed.
Merge conflicts are fine, we can handle them trivially, do not rewrite
history just for that.
