      [ARM] 3692/1: ARM: coswitch irq handling to the generic implementation · 4a2581a0
      Thomas Gleixner authored
      Patch from Thomas Gleixner
      
      From: Thomas Gleixner <tglx@linutronix.de>
      
      Switch the ARM irq core handling to the generic implementation. The
      ARM specific header files now contain mostly migration stubs and
      helper macros. Note that each machine type must be converted after
      this step seperately. This was seperated out from the patch for easier
      review.
      
      The main changes for the machine type code is the conversion of the
      type handlers to a 'type flow' and 'chip' model. This affects only the
      multiplex interrupt handlers. A conversion macro needs to be added to
      those implementations, which defines the data structure which is
      registered by the set_irq_chained_handler() macro.
      
      Some minor fixups of include files and the conversion of data
      structure access is necessary all over the place.
      
      The mostly macro based conversion was provided to allow an easy
      migration of the existing implementations.
      
      The code compiles on all defconfigs available in arch/arm/configs
      except those which were broken also before applying the conversion
      patches.
      
      The code has been boot and runtime tested on most ARM platforms. The
      results of an extensive testing and bugfixing series can be found

      [PATCH] Configurable NODES_SHIFT · c80d79d7
      Yasunori Goto authored
      Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for
      each arch.  Its definition is sometimes configurable.  Indeed, ia64 defines 5
      NODES_SHIFT values in the current git tree.  But it looks a bit messy.
      
      SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has
      been changeable by config.  Suitable node's number may be changed in the
      future even if it is other architecture.  So, I wrote configurable node's
      number.
      
      This patch set defines just default value for each arch which needs multi
      nodes except ia64.  But, it is easy to change to configurable if necessary.
      
      On ia64 the number of nodes can be already configured in generic ia64 and SN2
      config.  But, NODES_SHIFT is defined for DIG64 and HP'S machine too.  So, I
      changed it so that all platforms can be configured via CONFIG_NODES_SHIFT.  It
      would be simpler.

      [PATCH] spi: simple SPI framework · 8ae12a0d
      David Brownell authored
      This is the core of a small SPI framework, implementing the model of a
      queue of messages which complete asynchronously (with thin synchronous
      wrappers on top).
      
        - It's still less than 2KB of ".text" (ARM).  If there's got to be a
          mid-layer for something so simple, that's the right size budget.  :)
      
        - The guts use board-specific SPI device tables to build the driver
          model tree.  (Hardware probing is rarely an option.)
      
        - This version of Kconfig includes no drivers.  At this writing there
          are two known master controller drivers (PXA/SSP, OMAP MicroWire)
          and three protocol drivers (CS8415a, ADS7846, DataFlash) with LKML
          mentions of other drivers in development.
      
        - No userspace API.  There are several implementations to compare.
          Implement them like any other driver, and bind them with sysfs.
      
      The changes from last version posted to LKML (on 11-Nov-2005) are minor,
      and include:
      
        - One bugfix (removes a FIXME), with the visible effect of making device
          names be "spiB.C" where B is the bus number and C is the chipselect.
      
        - The "caller provides DMA mappings" mechanism now has kerneldoc, for
          DMA drivers that want to be fancy.
      
        - Hey, the framework init can be subsys_init.  Even though board init
          logic fires earlier, at arch_init ... since the framework init is
          for driver support, and the board init support uses static init.
      
        - Various additional spec/doc clarifications based on discussions
          with other folk.  It adds a brief "thank you" at the end, for folk
          who've helped nudge this framework into existence.
      
      As I've said before, I think that "protocol tweaking" is the main support
      that this driver framework will need to evolve.
      
      From: Mark Underwood <basicmark@yahoo.com>
      
        Update the SPI framework to remove a potential priority inversion case by
        reverting to kmalloc if the pre-allocated DMA-safe buffer isn't available.

      [ARM] Separate VIC (vectored interrupt controller) support from Versatile · fa0fe48f
      Russell King authored
      Other machines may wish to make use of the VIC support code, so
      move it to arch/arm/common.
