I get an error when trying to build this out of tree:

/home/cmarinas/work/linux/tools/testing/selftests/../../../tools/arch/arm64/include/asm/sysreg.h:132:10: fatal error: asm/sysreg-defs.h: No such file or directory
  132 | #include "asm/sysreg-defs.h"
      |          ^~~~~~~~~~~~~~~~~~~

Probably sysreg-defs.h has not been generated yet. Too late to figure it
out now.
