[RFC] Make printk() output better readable

[Nico Schottelius]

Hey devs,

When reading current dmesg, I notice that some messages have the
structure

 Introduction:
   <location>: <text>

Example:

[    0.000000] BIOS-provided physical RAM map:
[    0.000000]  BIOS-e820: 0000000000000000 - 000000000009ec00 (usable)
[...]

I also see

 <location>: <text>

Example:

[    0.000000] ACPI: RSDP 000F73A0, 0024 (r2 LENOVO)
[    0.000000] ACPI: XSDT 7C97BD45, 009C (r1 LENOVO TP-6D        1050  LTP        0)
[...]

Then, most of the stuff is simply

 <text>

[    0.000000] DMI present.
[    0.000000] last_pfn = 0x7ca00 max_arch_pfn = 0x100000000
[    0.000000] x86 PAT enabled: cpu 0, old 0x7040600070406, new 0x7010600070106


The first two blocks are somehow readable, the <text> only
is a bit painful to read. I personally would prefer to have
at least <location> (which may also be driver, hardware location, etc)
before each line, if it's not of type 1 (introduction + indent).

I think currently it is totally inconsistent, as seen, one
of the worst cases with TCP, here:

[    0.355604] NET: Registered protocol family 2
[    0.402669] IP route cache hash table entries: 65536 (order: 7, 524288 bytes)
[    0.403216] TCP established hash table entries: 262144 (order: 10, 4194304 bytes)
[    0.404925] TCP bind hash table entries: 65536 (order: 8, 1048576 bytes)
[    0.405538] TCP: Hash tables configured (established 262144 bind 65536)
[    0.405642] TCP reno registered

What do you think about it?

Sincerly,

Nico
