So ARM64 kernels are typically compiled with 3-level 4KB pages: CONFIG_ARM64_4K_PAGES=y # CONFIG_ARM64_64K_PAGES is not set CONFIG_ARM64_VA_BITS_39=y # CONFIG_ARM64_VA_BITS_48 is not set CONFIG_ARM64_VA_BITS=39 Does this mean that your patch won't work on such a kernel? If so, do you have any plans to add support for 4K 3-level pages?
