Maybe I'm missing something but this dropped the prefixes now
completely:

-e820: BIOS-provided physical RAM map:
+BIOS-provided physical RAM map:

-e820: last_pfn = 0x43f000 max_arch_pfn = 0x400000000
+last_pfn = 0x43f000 max_arch_pfn = 0x400000000

-e820: last_pfn = 0x9d000 max_arch_pfn = 0x400000000
+last_pfn = 0x9d000 max_arch_pfn = 0x400000000

...

I don't think that was the intention.
