This patch results in
include/linux/mmzone.h:1156:2: error: #error Allocator MAX_ORDER exceeds SECTION_SIZE
1156 | #error Allocator MAX_ORDER exceeds SECTION_SIZE
when building ia64:defconfig.
Also, PAGE_SHIFT is not defined, though I don't know if that is related.
Reverting the patch fixes the problem for me.
