The release is based on the Linux 4.4.75-rt88 version. That is I
applied the -rt88 patch on the 4.4.75-cip6 kernel and merged in all
CIP releases.

what is cip6?

CIP stands for Civil Infrastructure Platform [1]. Ben Hutchings maintains
the 4.4.x-cip kernel tree which is a super long stable tree [2].

So 4.4.x is maintained until Feb, 2022. I assumed that `cip' will take
over / help Greg with the v4.4 tree and won't include its "own" things.

Main CIP kernel policies can be found in the wiki: https://
wiki.linuxfoundation.org/civilinfrastructureplatform/cipkernelmaintenance

Some of the builds are failing (allmodconfig), though it

doesn't look cip-rt specific, eg:
    kernel/utilities/compiletest-runner at 2/build/../include/linux/compil
    er.h:484 call to ?__compiletime_assert_150? declared with attribute
    error: BUILD_BUG_ON failed: hw_flag_names[NUM_IEEE80211_HW_FLAGS]
    != (void *)0x1> >> 
Not sure how to handle those. IIRC, we don't support allmodconfig.

yes but adding

  68920c973254 ("net/mac80211/debugfs.c: prevent build failure with
  CONFIG_UBSAN=y")

could solve the issue.

Okay, I just don't know if Ben wants to add the patch to his tree though.

If the patch solves the issue then please forward the patch upstream.
The "normal" v4.4 stable tree is affected by this, too.

Thanks,
