Pushed everything else in the series *except* this one, because there
was a minor conflict. Please rebase and resend.

Sorry for the delay, and thanks for the patches and review.

A probably good follow-up clean up would be to define the missing masks
and remove the hardcoded things like this 0xf.

And also something that I had noticed on the previous patches but I forgot
to mention: it would be good as a followup to replace the local value << shift
per FIELD_PREP() helpers and remove the shift definitions...

But really nothing related directly with this patch. For this:

Oh, and I also noticed that CI didn't return yet for these patches...
https://patchwork.freedesktop.org/series/112438/

a strange delay... I will probably hit the retest if we don't get
anything by the end of the day today.

Thx for reviews.
Apparently CI missed this series, I have just hit retest.

this chunck got me really confused... you are now doing a lot more reads then before.
I'd say the previous approach is better and more readable than the new one...

Every read/write is replaced by exactly one rmw, nothing added, simple 
proof by reading the lines: previously 3 reads, 3 writes, now 3 rmw :)

> I'd say the previous approach is better and more readable than the new one...

You are right, even if functionally it is the same, the previous code 
better empahises we check if writes are effective.
I will send v3 without this chunk.
