implicit declaration of function 'ipipe_restore_pipeline_head'; did you mean did you mean 'ipipe_test_thread_flag'

Question

I'm trying to build an embedded OS with buildroot 2020.02 with 2 kernel. My Linux kernel is 4.19.107 and my Xenomai kernel is 3.1. I apply the Adeos patch in order to have the ipipe fetatures : ipipe-core-4.19.106-cip21-arm07 from this site : https://xenomai.org/downloads/ipipe/v4.x/arm/. The compilation work with an old kernel and an old xenomai version , but with this one I have compilation errors in /include/asm-generic/xenomai/hal.h and hal.c :

I search in the ipipe.h file but unfortunately none of those methods are defined here and I don't find the equivalent.

Does anyone knows if there is an issue ?
