      net drivers: fix platform driver hotplug/coldplug · 72abb461
      Kay Sievers 提交于
      Since 43cc71ee, the platform modalias is
      prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable network
      platform drivers, to re-enable auto loading.
      
      NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support.
      That looks problematic in the first place (it even uses the ancient "struct
      device_driver" binding scheme for platform_bus!) and I suspect it will vanish
      soonish when arch/powerpc rules the world.  Also, drivers/net/ne.c would have
      needed more thought to sort out.

      potential compiler error, irqfunc caller sites update · 0da2f0f1
      Yoann Padioleau 提交于
      In 7d12e780 David Howells performed
      this evolution:
       "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"
      
      He correctly updated many of the function definitions that were using this
      extra regs pointer parameter but forgot to update some caller sites of
      those functions.  The reason the modifications was not properly done on all
      drivers is that some drivers were rarely compiled because they are for
      AMIGA, or that some code sites were inside #ifdefs where the option is not
      set or inside #if 0.
      
      Here is the semantic patch that found the occurences
      and fixed the problem.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau 提交于
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).

      [PATCH] beginning of 8390 fixes - generic and arm/etherh · 6c3561b0
      Al Viro 提交于
      etherh and a handful of other odd drivers use different macros when building
      8390.c.  Since we generate a single 8390.o and then link with it, in any
      config with both oddball and normal 8390-based driver we will end up with
      breakage in at least one of them.  Solution: take most of 8390.c into
      lib8390.c and have 8390.c, etherh.c and the rest of oddballs #include it.
      Helper macros are taken from 8390.h to whoever includes lib8390.c.  That
      way odd drivers get separate instances of compiled 8390 stuff and stop
      stepping on each other's toes.  8390.h gets cleaned up - we don't have
      the cascade of ifdefs in there and are left with the stuff that can be
      used by any 8390-based driver.  Current problems are exactly because of
      that cascade - we attempt to choose the set of helpers by looking at config
      and that, of course, doesn't work well when we have several sets needed
      by various drivers in our config.

      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.
