      ray_cs: checkpatch.pl and Lindent cleanups · 141fa61f
      John Daiker 提交于
      Before: 1099 errors, 93 warnings, 2854 lines checked
      After:  19 errors, 47 warnings, 2976 lines checked
      
      The big bulk of this is code indent and over 80 character lines
      (Lindent did this part) Other changes are foo * bar spacing, and
      trailing whitespace.
      
      v2: Cleans up ill-indented comments.  Subsequently, this reduces the
      number of warnings, too.  Thanks to Joe Perches for pointing this out!
      
      v3: Ran the whole file through Lindent first... which does most of
      the work for me. :) Again, thanks to Joe Perches for this.
      
      This is my final answer!

      pcmcia: Fix up legacy driver IRQs · 47cbb110
      Alan Cox 提交于
      The PCMCIA layer obsoleted asking for per device private IRQS some years
      ago and all the drivers by inspection correctly use dev_id and handle
      shared interrupts [they get em anyway in most PCI bridged PCMCIA/Cardbus]
      so can be adjusted.
      
      This gets rid of the various bugs reported where there is spewage about
      conflicting irq types and sometimes the driver won't load.
      
      (Note I don't have all of these devices to test each one beyond by inspection)

      bugs galore:
      	* 0xf380 instead of htons(ETH_P_AARP), etc.  Works only on l-e.
      	* back in 2.3.20 driver got readb() and friends instead of
      direct dereferencing of iomem.  Somebody got too enthusiatic and replaced
      	ntohs(p->mrx_overflow)
      with
      	ntohs(read(&p->mrx_overflow)
      without noticing that (a) the sucker is 16bit and (b) that expression can't possibly
      be portable anyway (hell, on l-e it's always less than 256, on b-e it's always a
      multiple of 256).  Proper fix is
      	swab16(readw(&p->mrx_overflow)
      taking into account the conversion done by readw() itself.  That crap happened
      in several places; the same fix applies.
      	* untranslate() assumes little-endian almost everywhere, except for
      the code checking for IPX/AARP packets; there we forgot ntohs(), so that part
      only works on big-endian.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells 提交于
      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.
