So, I decided to check for pgtable_cache_init in arch/s390 and
include/asm-s390 but couldn't find it - I guess this is a mismerge
or something the S390 people missed.
pgtable_cache_init() must be implemented in all architectures. Any
that don't implement it must make the call a no-op as per the original
pgtable.h.
