It includes some backported hardware enablement and other minor features that aren't suitable for stable. I am helping with review for 4.4-stable and regularly merge it into 4.4-cip, but it's *not* planned for CIP to take over maintenance of stable branches. After EOL for 4.4-stable, 4.4-cip will get fixes for only the kernel components that CIP members use. > > > > https://ci-rt.linutronix.de/RT-Test/kbuild.jsp?id=112 > > > > > > > > Some of the builds are failing (allmodconfig), though it > > > > doesn't look cip-rt specific, eg: > > > > > > > > > > > > kernel/utilities/compiletest-runner@2/build/../include/linux/compiler.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.

Are some other configurations (or compiler versions) where this code fails to build? (I'm a bit surprised that it ever compiled!)
