While building Perf for arm, arm64, i386 and x86, all with GCC 11, the following errors were encountered:

  util/parse-events-hybrid.c: In function 'add_hw_hybrid':
  util/parse-events-hybrid.c:84:17: error: implicit declaration of function 'copy_config_terms'; did you mean 'perf_pmu__config_terms'? [-Werror=implicit-function-declaration]

The nbd problems persist on some Arm configurations with Clang (footbridge_defconfig, mini2440_defconfig, s3c2410_defconfig):
  ERROR: modpost: "__mulodi4" [drivers/block/nbd.ko] undefined!
