The default pmd_addr_end macro uses an unsigned long to represent the VA. When used with KVM and stage-2 translation, the VA is actually an IPA, which is up to 40 bits. This also affect the SMMU driver, which also deals with stage-2 translation.
Instead, provide an implementation that can cope with larger VAs by using a u64 instead. This version will overload the default one provided in include/asm-generic/pgtable.h.
