Hmmm... CONFIG_SPARSEMEM is not set if you do allnoconfig
config SPARSEMEM def_bool y depends on SPARSEMEM_MANUAL
So I guess we need to set SPARSEMEM_MANUAL
But arch/x86/Kconfig has
config SPARSEMEM_MANUAL bool "Sparse Memory" depends on ARCH_SPARSEMEM_ENABLE help This will be the only option for some systems, including memory hotplug systems. This is normal.
It needs to be not deselectable for x86_64.
Inserting
def_bool y if X86_64
did not help....
Somehow make menuconfig did not give me an ability to even enable this again.
