Commit 6b0f68e32ea8 ("mm: add utility for early copy from unmapped
ram") introduces a function copy_from_early_mem() into mm/early_ioremap.c
which itself calls early_memremap()/early_memunmap(). However, since
early_memunmap() has not been declared yet at this point in the .c file,
nor by any explicitly included header files, we are depending on a
transitive include of asm/early_ioremap.h to declare it, which is fragile.So instead, include this header explicitly.
