pmac mixer update from shadow register on resume and switching DRC on headphone plug

The attached patch improved the pmac driver by implementing updating the
mixer from the shadow register after a resume or headphone interrupt, as
well as automatically selecting DRC on headphone plug.

For normal line-out one does not want the DRC, but it should
automatically be reenabled after the headphone is unplugged: Otherwise
the power to the internal speakers is high enought to destroy them
(happend once to my iBook - when it still had warrenty ... ;-)

It looks fine to me, except that I decided to play chicken as far as the
give_sigsegv update of sa_handler is concerned.

Arun, I hope I got the ia32 emulation parts right, but you may want to
double-check.

The patch seems to work fine as far as I have tested.  I'm seeing some
oddity in context-switch overhead and pipe latency as reported by LMbench,
but I suspect that's due to another change that happened somewhere between
2.6.5-rc1 and Linus' bk tree as of this morning.

  Add the signal race changes to x86-64 to make it compile again.

  Didn't merge the more pointless changes from i386.

  Also remove the special SA_ONESHOT handling, doesn't seem to be needed
  anymore.

From: Mikael Pettersson <mikpe@csd.uu.se>

  The signal-race-fixes patch in 2.6.8-rc2-mm1 appears to have broken
  x86-64's ia32 emulation.

  When forcing a SIGSEGV the old code updated "*ka", where ka was a pointer
  to current's k_sigaction for SIGSEGV.  Now "ka_copy" points to a copy of
  that structure, so assigning "*ka_copy" doesn't do what we want.  Instead do
  the assignment via current->...  just like the normal signal delivery code
  does.

  Update s30 for the signal race fix

From: Mikael Pettersson <mikpe@csd.uu.se>

  The signal-race-fixes patch in 2.6.8-rc2-mm1 appears to be a bit broken on
  s390.

  When forcing a SIGSEGV the old code updated "*ka", where ka was a pointer
  to current's k_sigaction for SIGSEGV.  Now "ka_copy" points to a copy of
  that structure, so assigning "*ka_copy" doesn't do what we want.  Instead do
  the assignment via current->...  just like i386 and x86_64 do.

  Furthermore, the SA_ONESHOT handling wasn't deleted.  That is now handled
  by generic code in the kernel.

The problem:

  In arch/i386/signal.c, in the do_signal() function, it calls
  get_signal_to_deliver() which returns the signal number to deliver (along
  with siginfo).  get_signal_to_deliver() grabs and releases the lock, so
  the signal handler lock is not held in do_signal().  Then the do_signal()
  calls handle_signal(), which uses the signal number to extract the
  sa_handler, etc.

  Since no lock is held, it seems like another thread with the same
  signal handler set can come in and call sigaction(), it can change
  sa_handler between the call to get_signal_to_deliver() and fetching the
  value of sa_handler.  If the sigaction() call set it to SIG_IGN, SIG_DFL,
  or some other fundamental change, that bad things can happen.

The patch:

  You have to get the sigaction information that will be delivered while
  holding sighand->siglock in get_signal_to_deliver().

  In 2.4, it can be fixed per-arch and requires no change to the
  arch-independent code because the arch fetches the signal with
  dequeue_signal() and does all the checking.

The test app:

  The program below has three threads that share signal handlers.  Thread
  1 changes the signal handler for a signal from a handler to SIG_IGN and
  back.  Thread 0 sends signals to thread 3, which just receives them.
  What I believe is happening is that thread 1 changes the signal handler
  in the process of thread 3 receiving the signal, between the time that
  thread 3 fetches the signal info using get_signal_to_deliver() and
  actually delivers the signal with handle_signal().

  Although the program is obvously an extreme case, it seems like any
  time you set the handler value of a signal to SIG_IGN or SIG_DFL, you can
  have this happen.  Changing signal attributes might also cause problems,
  although I am not so sure about that.

  (akpm: this test app segv'd on SMP within milliseconds for me)
