A recent change ("MIPS: memblock: Discard bootmem initialization")
removed the reservation of all memory below the kernel's _end symbol in
bootmem. This makes the call to free_bootmem unnecessary, since the
memory region is no longer marked reserved.

Additionally, ("MIPS: memblock: Print out kernel virtual mem
layout") added a display of the kernel's virtual memory layout, so
printing the relocation information at this point is redundant.

Remove this section of code.

Missing your SoB.

I think this change should go after you introduce the new mechanism, i.e. after "MIPS: memblock: Print out kernel virtual mem layout", which should probably go nearer the start of the series.
