The check against VSID range is implied when we check task size against hash and radix pgtable range[1], because we make sure page table range cannot exceed vsid range.
[1] BUILD_BUG_ON(TASK_SIZE_USER64 > H_PGTABLE_RANGE); BUILD_BUG_ON(TASK_SIZE_USER64 > RADIX_PGTABLE_RANGE); The check for smaller task size is also removed here, because the follow up patch will support a tasksize smaller than pgtable range.
