s390/mm: zero page cache synonyms for zEC12 To avoid cache synonyms on System zEC12 32 independent zero pages are required, one for each combination for bits 2**12 to 2**16 of the virtual address. To avoid wasting too much memory on small virtual systems the number of zero pages is limited to 4 if the memory size is less or equal to 64MB.
