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 asperl -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.Signed-off-by: Jan Engelhardt

Before requesting firmware, printk a message saying what we're requesting. This
makes it easier to see what's going on, and provides an explanation for the
huge silent delay that one would otherwise get after accidentally building
ipw2200 as a non-module.Cc: Greg KH

The function thermal_cooling_device_register always returns either a valid
pointer or a value made with ERR_PTR, so a test for non-zero on the result
will always succeed.The problem was found using the following semantic match.

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.[akpm@linux-foundation.org: coding-style fixes]

Make /dev/kmem a config option; /dev/kmem is VERY rarely used, and when
used, it's generally for no good (rootkits tend to be the most common
users). With this config option, users have the choice to disable
/dev/kmem, saving some size as well.A patch to disable /dev/kmem has been in the Fedora and RHEL kernels for
4+ years now without any known problems or legit users of /dev/kmem.[akpm@linux-foundation.org: make CONFIG_DEVKMEM default to y]

Fix 18 errors and several warnings given by checkpatch.pl:
- use of C99 // comments;
- trailing whitespace;
- 'switch' and 'case' not at the same indentation level;
- no space before the open parenthesis of the 'if' and 'switch' statements;
- space between function name and open parenthesis (though I have introduced
such warnins in some places since the code looks prettier with the spaces);- including instead of ;
- line over 80 characters.
In addition to these changes, also do the following:
- make the arrays in sil_set_pio_mode() 'static', and make the arrays in
sil_set_dma_mode() 'static const';- change the string of the 'if' statements into the 'switch' statement in
sil_pata_udma_filter();- drop the needless '==' operators from the 'if' statements where a condition
is a mere bit test;- 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;
- remove needless curly braces and parentheses;
- fix typos, capitalize acronyms, etc. in the comments...

It's plain wrong for PCMCIA to select HAVE_IDE that implies e.g. the
availability of an asm/ide.hIt turns out this was done for ARM, and we can simply always select
HAVE_IDE on ARM instead of manually tracking which platforms might
possible have an IDE controller directly or indirectly.Signed-off-by: Adrian Bunk
