Back in the olden days we added support for using 64K pages to map the SPU (Synergistic Processing Unit) local store on Cell, when the main kernel was using 4K pages.
This was useful at the time because distros were using 4K pages, but using 64K pages on the SPUs could reduce TLB pressure there.
However these days the number of Cell users is approaching zero, and supporting this option adds unpleasant complexity to the memory management code.
So drop the option, CONFIG_SPU_FS_64K_LS, and all related code.
