[PATCH 5/9] blockconsole: use CON_ALLDATA

From: Joern Engel
Date: Thu Feb 28 2013 - 18:05:28 EST


Blockconsole should really see every message ever printed. The
alternative is to try debugging with information like this:
[166135.633974] Stack:
[166135.634016] Call Trace:
[166135.634029] <IRQ>
[166135.634156] <EOI>
[166135.634177] Code: 00 00 55 48 89 e5 0f 1f 44 00 00 ff 15 31 49 80 00 c9 c3 66 66 66 66 66 66 2e 0f 1f 84 00 00 00 00 00 55 48 89 e5 0f 1f 44 00 00
