I don't see it as an improvement. On the contrary, the output becomes
somewhat tautological:

memblock: memblock_reserve: smp_scan_config+0xa5/0xe9: [0x00000000000f5a60-0x00000000000f5a6f]
memblock: memblock_reserve: smp_scan_config+0xbc/0xe9: [0x00000000000f5a70-0x00000000000f5b83]
memblock: memblock_reserve: setup_arch+0x5d8/0xbcd: [0x0000000002e00000-0x0000000002e10fff]
memblock: memblock_add: e820__memblock_setup+0x5e/0x76: [0x0000000000001000-0x000000000009fbff]
memblock: memblock_add: e820__memblock_setup+0x5e/0x76: [0x0000000000100000-0x00000000bffdcfff]
memblock: memblock_add: e820__memblock_setup+0x5e/0x76: [0x0000000100000000-0x000000013fffffff]

And the output of memblock_dump_all() is perfectly fine without the prefix.

What is the base commit for this patch?
It seems it missed a pr_warn in memblock_cap_memory_range()...
