In 5.10 the hackkit defconfig does not select ARCH_KEEP_MEMBLOCK which is
required for memblock_is_map_memory() to function after boot.
In upstream kernels ARCH_KEEP_MEMBLOCK is always selected by ARM after
commit 5e545df3292f ("arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL")
So the fix would be either to backport 5e545df3292f or unconditionally
select ARCH_KEEP_MEMBLOCK on ARM in 5.10.
(the same applies to 5.4)
Greg, what is your preference?

I'll defer to you all, but normally I prefer whatever is in Linus's
