      parisc: remove driver_data direct access of struct device · d18dbfa7
      Greg Kroah-Hartman authored
      In the near future, the driver core is going to not allow direct access
      to the driver_data pointer in struct device.  Instead, the functions
      dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
      have been around since the beginning, so are backwards compatible with
      all older kernel versions.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau authored
      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).

      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] genirq: rename desc->handler to desc->chip · d1bef4ed
      Ingo Molnar authored
      This patch-queue improves the generic IRQ layer to be truly generic, by adding
      various abstractions and features to it, without impacting existing
      functionality.
      
      While the queue can be best described as "fix and improve everything in the
      generic IRQ layer that we could think of", and thus it consists of many
      smaller features and lots of cleanups, the one feature that stands out most is
      the new 'irq chip' abstraction.
      
      The irq-chip abstraction is about describing and coding and IRQ controller
      driver by mapping its raw hardware capabilities [and quirks, if needed] in a
      straightforward way, without having to think about "IRQ flow"
      (level/edge/etc.) type of details.
      
      This stands in contrast with the current 'irq-type' model of genirq
      architectures, which 'mixes' raw hardware capabilities with 'flow' details.
      The patchset supports both types of irq controller designs at once, and
      converts i386 and x86_64 to the new irq-chip design.
      
      As a bonus side-effect of the irq-chip approach, chained interrupt controllers
      (master/slave PIC constructs, etc.) are now supported by design as well.
      
      The end result of this patchset intends to be simpler architecture-level code
      and more consolidation between architectures.
      
      We reused many bits of code and many concepts from Russell King's ARM IRQ
      layer, the merging of which was one of the motivations for this patchset.
      
      This patch:
      
      rename desc->handler to desc->chip.
      
      Originally i did not want to do this, because it's a big patch.  But having
      both "desc->handler", "desc->handle_irq" and "action->handler" caused a
      large degree of confusion and made the code appear alot less clean than it
      truly is.
      
      I have also attempted a dual approach as well by introducing a
      desc->chip alias - but that just wasnt robust enough and broke
      frequently.
      
      So lets get over with this quickly.  The conversion was done automatically
      via scripts and converts all the code in the kernel.
      
      This renaming patch is the first one amongst the patches, so that the
      remaining patches can stay flexible and can be merged and split up
      without having some big monolithic patch act as a merge barrier.

      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!
