This was fixed in v5.11-rc1, but reappeared in v5.12-rc1?

Do you know what fixed in for 5.11?  I guess for PPC64 we depend on CONFIG_VSX?

Looking at the kisskb build logs for v5.11*, it seems compilation never
got to drivers/gpu/drm/ due to internal compiler errors that weren't caught
by my scripts.  So the errors listed above were not really fixed.

As far as I can see, the problem has been there for any config without CONFIG_VSX from the beginning 
ie since https://github.com/linuxppc/linux/commit/16a9dea110a6

The following should fix it up:

diff --git a/arch/powerpc/include/asm/switch_to.h b/arch/powerpc/include/asm/switch_to.h

As far as I can see, the problem has been there for any config without CONFIG_VSX from the beginning 
ie since https://github.com/linuxppc/linux/commit/16a9dea110a6

The following should fix it up:

diff --git a/arch/powerpc/include/asm/switch_to.h b/arch/powerpc/include/asm/switch_to.h
index fdab93428372..9d1fbd8be1c7 100644

  #endif

  #ifdef CONFIG_SPE
