I'm still getting this build failure when typing 'make' in
tools/testing/selftests/x86:
gcc -m32 -o /home/mingo/tip/tools/testing/selftests/x86/protection_keys_32 -O2
-g -std=gnu99 -pthread -Wall -no-pie protection_keys.c -lrt -ldl -lm

Plus I'm also getting these warnings even with all your fixes applied:
