This series adds the following new generic fallbacks. Before that it drops __HAVE_ARCH_HUGE_PTEP_GET from arm64 platform.
1. is_hugepage_only_range() 2. 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-rc4. After this arm (32 bit) remains the sole platform defining it's own huge_ptep_get() via __HAVE_ARCH_HUGE_PTEP_GET. Changes in V2: - Adopted "#ifndef func" method (adding a single symbol to namespace) per Andrew - Updated the commit messages in [PATCH 2/3] and [PATCH 3/3] as required Changes in V1: (https://patchwork.kernel.org/project/linux-mm/list/?series=270677) Cc: Russell King <li...@armlinux.org.uk> Cc: Catalin Marinas <catalin.mari...@arm.com> Cc: Will Deacon <w...@kernel.org> Cc: Tony Luck <tony.l...@intel.com> Cc: Fenghua Yu <fenghua...@intel.com> Cc: Thomas Bogendoerfer <tsbog...@alpha.franken.de> Cc: "James E.J.
