Why is arm > special? The version of the function __zs_unmap_object() which uses flush_tlb_kernel_range() in the zsmalloc driver is only compiled in when USE_PGTABLE_MAPPING is defined. And USE_PGTABLE_MAPPING is defined in the same file only when CONFIG_ARM is defined. So this happens only on ARM.
