Since you defined HAVE_MEMBLOCK_PFN_VALID here, do we need to define it in the arch code as well? If kept it in the mm/Kconfig only, you could just select it in the arch HAVE_ARCH_PFN_VALID entry:
diff --git a/arch/arm64/Kconfig b/arch/arm64/Kconfig index d0a53cc6293a..cd230c77e122 100644 --- a/arch/arm64/Kconfig +++ b/arch/arm64/Kconfig @@ -787,6 +787,7 @@ config ARCH_FLATMEM_ENABLE config HAVE_ARCH_PFN_VALID def_bool ARCH_HAS_HOLES_MEMORYMODEL || !SPARSEMEM + select HAVE_MEMBLOCK_PFN_VALID config HW_PERF_EVENTS def_bool y (similarly for arch/arm)
