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.

This can be triggered with root help only, but...
Register the ":text:E::txt::/root/cat.txt:' rule in binfmt_misc (by root) and
try launching the cat.txt file (by anyone) :) The result is - the endless
recursion in the load_misc_binary -> open_exec -> load_misc_binary chain and
stack overflow.
There's a similar problem with binfmt_script, and there's a sh_bang memner on
linux_binprm structure to handle this, but simply raising this in binfmt_misc
may break some setups when the interpreter of some misc binaries is a script.
So the proposal is to turn sh_bang into a bit, add a new one (the misc_bang)
and raise it in load_misc_binary. After this, even if we set up the misc ->
script -> misc loop for binfmts one of them will step on its own bang and
exit.

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.

I noticed that 2.6.24.2 calculates bprm->argv_len at do_execve(). But it
doesn't update bprm->argv_len after "remove_arg_zero() +
copy_strings_kernel()" at load_script() etc.
audit_bprm() is called from search_binary_handler() and
search_binary_handler() is called from load_script() etc. Thus, I think the
condition check
if (bprm->argv_len > (audit_argv_kb << 10))
return -E2BIG;
in audit_bprm() might return wrong result when strlen(removed_arg) !=
strlen(spliced_args). Why not update bprm->argv_len at load_script() etc. ?
By the way, 2.6.25-rc3 seems to not doing the condition check. Is the field
bprm->argv_len no longer needed?

Add a few __ref to tech modpost to ignore the references.
This is just papering over the fact that the cpu hotplug code is fragile with
