      isdn: whitespace coding style cleanup · 475be4d8
      Joe Perches authored
      isdn source code uses a not-current coding style.
      
      Update the coding style used on a per-line basis
      so that git diff -w shows only elided blank lines
      at EOF.
      
      Done with emacs and some scripts and some typing.
      
      Built x86 allyesconfig.
      No detected change in objdump -d or size.

      drivers/isdn/gigaset: tasklet_init - Remove unnecessary leading & from second arg · 5452fee2
      Joe Perches authored
      Changed function pointer use from non-majority address-of style
      to majority short form without & via:
      
      grep -rPl "\btasklet_init\s*\([^,\)]+,\s*\&" drivers/isdn | while read file ; do \
              perl -i -e 'local $/; while (<>) { s@(\btasklet_init\s*\([^,\)]+,\s*)\&@\1@g ; print ; }' $file ;\
      done
      
      Compile tested allyesconfig x86

      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.

      USB: Dealias -110 code (more complete) · 38e2bfc9
      Pete Zaitcev authored
      The purpose of this patch is to split off the case when a device does
      not reply on the lower level (which is reported by HC hardware), and
      a case when the device accepted the request, but does not reply at
      upper level. This redefinition allows to diagnose issues easier,
      without asking the user if the -110 happened "immediately".
      
      The usbmon splits such cases already thanks to its timestamp, but
      it's not always available.
      
      I adjusted all drivers which I found affected (by searching for "urb").
      Out of tree drivers may suffer a little bit, but I do not expect much
      breakage. At worst they may print a few messages.
