Subject: [PULL] blockconsole and netconsole changes

Linus,

please pull the bcon2 tree.  It mainly contains blockconsole, which
allows directing printk to a block device (usually a cheap usb key).
Given your preference for WARN_ON_ONCE over BUG_ON, you might actually
have some personal interest.

CON_ALLDATA changes behaviour for blockconsole and netconsole.  They
now receive all messages, independent of console_loglevel.  I
personally have found this immensely useful and on a fundamental level
there really is no argument for having the same filter on a
user-interactive console and a debugging-only message dump.

All but the last two commit have soaked in -next for some weeks.  The
last two are a trivial bugfix with several machineyears of testing and
a documentation change.  Neither should collide with anyone else's
tree.

The following changes since commit 19f949f52599ba7c3f67a5897ac6be14bfcb1200:
