Before that it drops __HAVE_ARCH_HUGE_PTEP_GET from arm64 platform. 1. HAVE_ARCH_IS_HUGEPAGE_ONLY_RANGE - is_hugepage_only_range() 2. HAVE_ARCH_CLEAR_HUGEPAGE_FLAGS - arch_clear_hugepage_flags() This has been boot tested on arm64 and x86 platforms but built tested on some more platforms including the changed ones here. This series applies on v5.7-rc1. After this arm (32 bit) remains the sole platform defining it's own huge_ptep_get() via __HAVE_ARCH_HUGE_PTEP_GET.
