      ALSA: cs4236: update control names · b753e03e
      Krzysztof Helt authored
      Update control names to be more closer to their meaning.
      Change the "Mono" name to the "Beep" as this line is usually
      used to forward the PC beeper signal to sound card's output.
      Update names for both cs423x and wss.
      Clean up cs4235 controls according to the cs4235 doc. Rename
      some of the cs4235 controls to be consistent with the cs4236's
      Also, delete one misnamed cs4231 register define.

      ALSA: cs4236: detect chip in one pass · d114cd84
      Krzysztof Helt authored
      The cs4236 was two step detection with call to the snd_wss_free()
      between two steps. The snd_wss_free() did not free a sound device
      created in the snd_wss_create(). This caused an OOPS during module
      removal as the same sound device was released twice. The same OOPS
      happened if the cs4236 module loading failed.
      Fix this by adapting the snd_cs4236_create() to correctly work with
      chips less capable then cs4236. The snd_cs4236_create() behaves the
      same as the snd_wss_create() if the chip is less capable than the cs4236.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells authored
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      	struct pt_regs *old_regs = set_irq_regs(regs);
      And put the old one back at the end:
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      In timer_interrupt(), this sort of change will be necessary:
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      Some notes on the interrupt handling in the drivers:
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
       (*) Various IRQ handler function pointers have been moved to type
