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]

In Documentation/sysrq.txt, the description of 'h' says that any key not
listed *above* will generate help. That's obviously not true since all the
keys listed below 'h' will do what they are described to do, not display help.
So change the text so that it says that any key not listed in the table will
generate help, which is what really happens.Signed-off-by: Jesper Juhl

Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the
Help message.It was previously done via X, but X is already used for Xmon on ppc & powerpc
platforms and this collision needs to be avoided.All callers of register_sysrq_key() are now marked in the sysrq op/key table.
I didn't mark 'h' as Help because Help is just printed for any unknown key,
such as '?'.Added some omitted sysrq key entries in the sysrq.txt file.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
