Remove proc_root export. Creation and removal works well if parent PDE is
supplied as NULL -- it worked always that way.
So, one useless export removed and consistency added, some drivers created
PDEs with &proc_root as parent but removed them as NULL and so on.

The "run_to_completion" mode was somewhat broken. Locks need to be avoided in
run_to_completion mode, and it shouldn't be used by normal users, just
internally for panic situations.
This patch removes locks in run_to_completion mode and removes the user call
for setting the mode. The only user was the poweroff code, but it was easily
converted to use the polling interface.

This adds support for OLPC XO hardware. Open Firmware on XOs don't contain
the VSA, so it is necessary to emulate the PCI BARs in the kernel. This also
adds functionality for running EC commands, and a CONFIG_OLPC.
A number of OLPC drivers depend upon CONFIG_OLPC.
olpc_ec_timeout is a hack to work around Embedded Controller bugs.

A command that causes a line feed while a background color is active,
such as
perl -e 'print "x" x 60, "\e[44m", "x" x 40, "\e[0m\n"'
and
perl -e 'print "x" x 40, "\e[44m\n", "x" x 40, "\e[0m\n"'
causes the line that was started as a result of the line feed to be completely
filled with the currently active background color instead of the default
color.
When scrolling, part of the current screen is memcpy'd/memmove'd to the new
region, and the new line(s) that will appear as a result are cleared using
memset. However, the lines are cleared with vc->vc_video_erase_char, causing
them to be colored with the currently active background color. This is
different from X11 terminal emulators which always paint the new lines with
the default background color (e.g. `xterm -bg black`).
The clear operation (\e[1J and \e[2J) also use vc_video_erase_char, so a new
vc->vc_scrl_erase_char is introduced with contains the erase character used
for scrolling, which is built from vc->vc_def_color instead of vc->vc_color.

SysRQ-P is not always useful on SMP systems, since it usually ends up showing
the backtrace of a CPU that is doing just fine, instead of the backtrace of
the CPU that is having problems.
This patch adds SysRQ show-all-cpus(L), which shows the backtrace of every
active CPU in the system. It skips idle CPUs because some SMP systems are
just too large and we already know what the backtrace of the idle task looks
like.

- no space before the open parenthesis of the 'if' and 'switch' statements;
- space between function name and open parenthesis (though I have introduced

- including <asm/io.h> instead of <linux/io.h>;
- line over 80 characters.
In addition to these changes, also do the following:

- change the string of the 'if' statements into the 'switch' statement in

- remove needless initializer for the 'tmp' variable in init_chipset_siimage();
- beautify groups of the variable initializers and assignment operators;
- add new line after variable definitions;
- remove new line between the comment and the statements it refers to;
