If that's the path to get this series merged for this cycle then yes,
but let's see if Hans agrees (sorry that I didn't know this before
posting).

One additional detail is that this series is on top of linux-next, which
has two additional mlxbf-pmc changes:

* 
https://lore.kernel.org/lkml/39be055af3506ce6f843d11e45d71620f2a96e26.1707808180.git.shravankr@nvidia.com/
* 
https://lore.kernel.org/lkml/d8548c70339a29258a906b2b518e5c48f669795c.1707808180.git.shravankr@nvidia.com/

Maybe those two should be included for 6.8 as well?
