So we traded implicit declaration errors:

  - /kisskb/src/drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dcn_calcs.c:
error: implicit declaration of function 'disable_kernel_vsx'
[-Werror=implicit-function-declaration]: 674:2 =>
  - /kisskb/src/drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dcn_calcs.c:
error: implicit declaration of function 'enable_kernel_vsx'
[-Werror=implicit-function-declaration]: 638:2 =>

for compile-time assertions.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
