      [VIDEO]: Fix section mismatch warning in promcon. · 353076fe
      Sam Ravnborg authored
      
      
      Fix the following warnings in promcon:
      WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x480): Section mismatch: reference to .init.data:promfont_unitable (between 'promcon_init_unimap' and 'promcon_init')
      WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x488): Section mismatch: reference to .init.data:promfont_unitable (between 'promcon_init_unimap' and 'promcon_init')
      WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x48c): Section mismatch: reference to .init.data:promfont_unicount (between 'promcon_init_unimap' and 'promcon_init')
      WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x490): Section mismatch: reference to .init.data:promfont_unicount (between 'promcon_init_unimap' and 'promcon_init')
      
      The warnings happens because the function: promcon_init_unimap()
      references promfont_unitable and promfont_unicount which are marked
      __initdata by the conmakehash command in the drivers/video/console/Makefile
      
      Fix the warning by removing the __initdata marker on the two variables.

      [PARISC] fix section mismatch in parisc STI video drivers · 48a7d5c6
      Helge Deller authored
      
      
      Hi Kyle,
      
      this patch fixes various section mismatches in the sti graphics driver:
      WARNING: drivers/built-in.o(.text.sticore_pci_init+0xac): Section mismatch: reference to .init.text:sti_try_rom_generic (after 'sticore_pci_init')
      WARNING: drivers/built-in.o(.text.sticore_pci_init+0xe4): Section mismatch: reference to .init.text:sticore_check_for_default_sti (after 'sticore_pci_init')
      WARNING: drivers/built-in.o(.text.sti_get_rom+0x18): Section mismatch: reference to .init.text:sti_init_roms (after 'sti_get_rom')
      (and others).
      
      Basically it's a replacement of __init by __devinit.
      Please apply, Helge

      backlight/fbcon: Add FB_EVENT_CONBLANK · 994efacd
      Richard Purdie authored
      
      
      The backlight class wants notification whenever the console is blanked
      but doesn't get this when hardware blanking fails and software blanking
      is used. Changing FB_EVENT_BLANK to report both would be a behaviour
      change which could confuse the console layer so add a new event for
      software blanking and have the backlight class listen for both.

      [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.
