      [IOC3] Fix section missmatch · 725e49c5

      WARNING: drivers/net/built-in.o(.text+0x3468): Section mismatch in reference fro
      m the function ioc3_probe() to the function .devinit.text:ioc3_serial_probe()
      The function ioc3_probe() references
      the function __devinit ioc3_serial_probe().
      This is often because ioc3_probe lacks a __devinit
      annotation or the annotation of ioc3_serial_probe is wrong.

      IOC3: Program UART predividers. · 0491d1f3
      Ralf Baechle authored
      
      The IOC3 driver's UART detection bits used to rely on the the firmware
      setting the UART pre-divider in a way that's apropriate for the 8250
      driver which doesn't currently program this register.  This happens
      to work for the console but not rarely for additional ports.
      
      While at it, also program the UART to RS-232 PIO mode; it the UART might
      have been in mac-serial and/or DMA mode though that hasn't actually been
      observed in practice.

      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
      handling.
      
      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:
      
      	set_irq_regs(old_regs);
      
      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
           irq_handler_t.

      [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] IOC3 fixes · 852ea22a
      Ralf Baechle authored
      
       - Using the right register clearly improves chances of getting the MII
         code and thus the driver working at all.
       - On startup check the media type before setting up duplex or we might
         spend the first 1.2s with a wrong duplex setting.
       - Get rid of whitespace lines.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds authored
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
