Since we started building with gcc-11 last weekend and started
noticing these build failures on stable-rc, mainline and next.
and today's stable-rc review also failed with these combinations.

Linux next master with gcc-11 - powerpc-defconfig - FAILED
Linux mainline master with gcc-11 - powerpc-defconfig - FAILED
stable rc Linux 5.14.2-rc1 with gcc-11 - powerpc-defconfig - FAILED
stable rc Linux 5.13.15-rc1 with gcc-11 - powerpc-defconfig - FAILED
stable rc Linux 5.10.63-rc1 with gcc-11 - powerpc-defconfig - FAILED

FYI,
The following powerpc config build PASS with gcc-11
  - allnoconfig
  - mpc83xx_defconfig
  - tqm8xx_defconfig
  - maple_defconfig
  - cell_defconfig
  - ppc64e_defconfig
  - ppc6xx_defconfig
