I was not suggesting to not fix FW. The idea was two fold. We cannot support different hugetlb page sizes. They need to be supported at linux page table level. So a generic check like is_power_of_2/4() may not be what we want. The second is to document clearly what are the different page sizes supported by a platform. -aneesh
