Petr Mladek 571079f5ba Documentation/serial-console: Document the behavior when the last console= parameter is not used
The console= kernel command-line parameter defines where the kernel
messages appear. It can be used multiple times to make the kernel log
visible on more devices.

The ordering of the console= parameters is important. In particular,
the last one defines which device can be accessed also via /dev/console.

The behavior is more complicated when the last console= parameter is
ignored by kernel. It might be surprising because it was not intentional.
The kernel just works this way historically.

There were few attempts to change the behavior. Unfortunately, it can't
be done because it would break existing users. Document the historical
behavior at least.

Mauro Carvalho Chehab 9d85025b04 docs-rst: create an user's manual book
Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters

As we'll be numbering the user's manual, remove the manual
numbering from SecurityBugs.
