      netdevice: safe convert to netdev_priv() #part-2 · 4cf1653a
      Wang Chen authored
      We have some reasons to kill netdev->priv:
      1. netdev->priv is equal to netdev_priv().
      2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
         netdev_priv() is more flexible than netdev->priv.
      But we cann't kill netdev->priv, because so many drivers reference to it
      This patch is a safe convert for netdev->priv to netdev_priv(netdev).
      Since all of the netdev->priv is only for read.
      But it is too big to be sent in one mail.
      I split it to 4 parts and make every part smaller than 100,000 bytes,
      which is max size allowed by vger.

      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

      [PATCH] Remove more unnecessary driver printk's · d5b20697
      Andy Gospodarek authored
      As I promised last week, here is the first pass at removing all
      unnecessary printk's that exist in network device drivers currently in
      promiscuous mode.  The duplicate messages are not needed so they have
      been removed.  Some of these drivers are quite old and might not need an
      update, but I did them all anyway.
      I am currently auditing the remaining conditional printk's and will send
      out a patch for those soon.

      [PATCH] m68knommu: FEC driver event/irq fixes · 0e702ab3
      Greg Ungerer authored
      Collection of fixes for the ColdFire FEC ethernet driver:
      . reworked event setting so that it occurs after the MII setup.
        roucaries bastien <roucaries.bastien@gmail.com>
      . Do not read cbd_sc in memory for each bit we test. Once per buffer is enough.
      . Overrun errors must increase `rx_fifo_errors', not `rx_crc_errors'
      . No need for a special value to activate rx or tx.  Only write access matters.
      . Simplify parameter of eth_copy_and_sum : `data' has already the right value.
      . Some spelling fixes.
