This is a quick hack to overcome the fact that SRCU currently does not
allow static initializers, and we need to sometimes initialize those
things before any other initializers (even "core" ones) can do so.
Currently we don't allow this at all for modules, and the only user that
needs is right now is cpufreq. As reported by Thomas Gleixner:

Again.
This same bug has now been introduced twice: it was done earlier by
commit b8d35192c5, only to be reverted
last time in commit 72945b2b90.
We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or
threads.
Keeping events within the one deferred execution thread automatically
throttles the events properly.
At least the Compaq N620c will lock up completely on the first thermal
event without this patch reverted.

When showing the stack backtrace, make sure that we never accept not
only an unchanging frame pointer, but also a frame pointer that moves
back down the stack frame. It must always grow up (toward older stack
frames).
I doubt this has triggered, but a subtly corrupt stack with extremely
unlucky contents could cause us to loop forever on a bogus endless frame
pointer chain.
This review was triggered by much worse problems happening in some of
the other stack unwinding code.

a quick look at cpu_idle_wait() shows how broken that code is
on i386: it changes the init task's affinity map but never
restores it ...
and because all userspace tasks get forked by init, they all
inherited that single-CPU affinity mask. x86_64 cloned this
bug too.

this crash happened because it did not sanitize the dwarf2 data it
got, and got an unaligned stack pointer - which happily walked past
the process stack (and eventually reached the end of kernel memory
and pagefaulted there) due to this naive iteration condition:
HANDLE_STACK (((long) stack & (THREAD_SIZE-1)) != 0);
note that i386 is alot more conservative when it comes to trusting
stack pointers:
static inline int valid_stack_ptr(struct thread_info *tinfo, void *p)
{
return p > (void *)tinfo &&
p < (void *)tinfo + THREAD_SIZE - 3;
}
but the x86_64 code did not take this bit of i386 code.
The fix is to align the stack pointer.

Benh points out that the msgs[0].flags entry never got initialized, and
since it's an automatic stack allocation, it could have any random
value, which is bad.
Rewrite the initializer to explicitly initialize all fields of the small
i2c_msg structure array we generate. Just to keep it all obvious, let's
handle msgs[1].buf in the same initializer while we're at it, instead of
initializing that one separately later.

similar to the version in adbhid_input_register(): The '<>' key and the
'^°' key on a german keyboard is swapped. Provide correct keys to
userland, external USB keyboards will not work correctly when the
'badmap'/'goodmap' workarounds from xkeyboard-config are used.
It is expected that distributions drop the badmap/goodmap part from
keycodes/macintosh in the xkeyboard-config package.
