VCHIQ patch and contrib code. Compiling with newer version LLVM / CLANG, and find errors in VCHIQ code

Hello fellow  Rpi4B users

Is VCHIQ compiling and installing for your use on your Raspberry Pi 4B?

The /usr/src  compile is breaking for me with -wunsigned_interger  cast 
being used (unsigned int) for a 32 bit result .

Try substituting  (unsigned long)  for a 64 bit result

ps.  Does the  make -j4 buildkernel buildworld TARGET_ARCH=aarch64  
KERNCONF=GENERIC-VCHIQ
work, finish, & complete for other users?

root@generic-arm64:/usr/src # make -j4 buildworld buildkernel

Look forward to hearing your results.
