Note that even with all the patches applied, a build warning remains:

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
protection_keys.c: In function ‘dumpit’:
protection_keys.c:419:3: warning: ignoring return value of ‘write’, declared with 
attribute warn_unused_result [-Wunused-result]
   write(1, buf, nr_read);
   ^~~~~~~~~~~~~~~~~~~~~~

Thanks,
