Excerpts from Christophe Leroy's message of November 26, 2021 3:52 am:

CONFIG_PPC_MM_SLICES is always selected by hash book3s/64.
CONFIG_PPC_MM_SLICES is never selected by other platforms.

Remove it.

I guess there is some remnants of code/data to build 64s hash without 
slices. Maybe without any huge page support? I guess it's probably
broken if it never =n, and not worth maintaining anyway?
