We are coding the kernel link address into the makefiles, which is invisibly dependent on PAGE_OFFSET. If PAGE_OFFSET is changed, the makefiles also need to be changed. Make adjustments such that the makefiles encode just the offset from PAGE_OFFSET for the kernel link address, and use PAGE_OFFSET in the linker scripts directly.
