Foregive me my ignorance..
Why is this relevant for sparc64 but not for sparc32?

A quick grep showed up only this in sparc32 specific files:

mm/init_32.c:DEFINE_PER_CPU(struct mmu_gather, mmu_gathers);

Maybe this is just something sparc32 does not support?

sparc32 uses include/asm-generic/tlb.h, whereas sparc64 implements its
own variant.

Ahh, thanks!
