      sh: Tie sparseirq in to Kconfig. · 54ff328b
      Paul Mundt 提交于
      Now that the dependent patches are merged, we are ready to enable
      sparseirq support. This simply adds the Kconfig option, and then converts
      from the _cpu to the _node allocation routines to follow the upstream
      sparseirq API changes.

      Paul Mundt 提交于
      irq_to_desc_alloc_cpu() has been renamed to irq_to_desc_alloc_node() in
      -next, but as we can not presently enable SPARSE_IRQ without the early
      irq_desc alloc patch, protect it with an ifdef until the interface has
      settled and we are ready to enable it system-wide.

      sh: irq: Teach ipr and intc about dynamically allocating irq_descs. · 05ff3004
      Paul Mundt 提交于
      This hooks in irq_to_desc_alloc_cpu() to the necessary code paths in the
      intc and ipr controller registration paths. As these are the primary call
      paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready.
      
      There is the added benefit now that each CPU contains specific IPR and
      INTC tables, so only the vectors with interrupt sources backing them will
      ever see an irq_desc instantiation. This effectively packs irq_desc
      down to match the CPU, rather than padding NR_IRQS out to cover the valid
      vector range.
      
      Boards with extra sources will still have to fiddle with the nr_irqs
      setting, but they can continue doing so through the machvec as before.

      sh: multiple vectors per irq - base · bdaa6e80
      Magnus Damm 提交于
      Instead of keeping the single vector -> single linux irq mapping
      we extend the intc code to support merging of vectors to a single
      linux irq. This helps processors such as sh7750, sh7780 and sh7785
      which have more vectors than masking ability. With this patch in
      place we can modify the intc tables to use one irq per maskable
      irq source. Please note the following:
      
       - If multiple vectors share the same enum then only the
         first vector will be available as a linux irq.
      
       - Drivers may need to be rewritten to get pending irq
         source from the hardware block instead of irq number.
      
      This patch together with the sh7785 specific intc tables solves
      DMA controller irq issues related to buggy interrupt masking.

      sh: maple: Support block reads and writes. · b233b28e
      Adrian McMenamin 提交于
      This patch updates the maple bus to support asynchronous block reads
      and writes as well as generally improving the quality of the code and
      supporting concurrency (all needed to support the Dreamcast visual
      memory unit - a driver will also be posted for that).
      
      Changes in the bus driver necessitate some changes in the two maple bus
      input drivers that are currently in mainline.
      
      As well as supporting block reads and writes this code clean up removes
      some poor handling of locks, uses an atomic status variable to serialise
      access to devices and more robusly handles the general performance
      problems of the bus.

      maple: fix device detection · bd496669
      Adrian McMenamin 提交于
      The maple bus driver that went into the kernel mainline in September 2007
      contained some bugs which were revealed by the update of the kobj code
      for the current release series. Unfortunately those bugs also helped
      ensure maple devices were properly detected. This patch (against the
      current git) now ensures that devices are properly detected again.
      
      (A previous attempt to fix this by delaying initialisation only partially
       fixed this - as became apparent when the bus was fully loaded)

      sh: Add maple bus support for the SEGA Dreamcast. · 17be2d2b
      Adrian McMenamin 提交于
      The Maple bus is SEGA's proprietary serial bus for peripherals
      (keyboard, mouse, controller etc). The bus is capable of some
      (limited) hotplugging and operates at up to 2 M/bits.
      
      Drivers of one sort or another existed/exist for 2.4 and a rudimentary
      port, which didn't support the 2.6 device driver model was also in
      existence.
      
      This driver - for the bus logic itself and for the keyboard (other
      drivers will follow) are based on the code and concepts of those old
      drivers but have lots of completely rewritten parts.
      
      I have the maple bus code as a built in now as that seems the sane and
      rational way to handle something like that - you either want the bus
      or you don't.

      [PATCH] superhyway: multiple block support and VCR rework · 055a2512
      Paul Mundt 提交于
      This extends the API somewhat to allow for platform-specific VCR reading and
      writing.  Some platforms (like SH4-202) implement the VCR in a split VCRL and
      VCRH, but end up being in reverse order or have other quirks that need to be
      dealt with, so we add a set of superhyway_ops per-bus to accomodate this.
      
      We also have to extend the per-device resources somewhat, as some devices now
      conveniently split control and data blocks.  So we allow a platform to
      register its set of SuperHyway devices via superhyway_add_devices() with the
      control block always ordered as the first resource (as this is the one that
      userspace cares about).

      [PATCH] fix missing includes · 4e57b681
      Tim Schmielau 提交于
      I recently picked up my older work to remove unnecessary #includes of
      sched.h, starting from a patch by Dave Jones to not include sched.h
      from module.h. This reduces the number of indirect includes of sched.h
      by ~300. Another ~400 pointless direct includes can be removed after
      this disentangling (patch to follow later).
      However, quite a few indirect includes need to be fixed up for this.
      
      In order to feed the patches through -mm with as little disturbance as
      possible, I've split out the fixes I accumulated up to now (complete for
      i386 and x86_64, more archs to follow later) and post them before the real
      patch.  This way this large part of the patch is kept simple with only
      adding #includes, and all hunks are independent of each other.  So if any
      hunk rejects or gets in the way of other patches, just drop it.  My scripts
      will pick it up again in the next round.

      Linus Torvalds 提交于
      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!
