Subject: [PATCH] powerpc: xor_vmx: Add '-mhard-float' to CFLAGS

I have attached a backport that will work for 5.15 and earlier. I think
you worked around this conflict in 5.15 by taking 04e85bbf71c9 but I am
not sure that is a smart idea. I think it might just be better to drop
that dependency and apply this version in 5.15.

Cheers,
Nathan
