      [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
      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
      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.

      [PATCH] ppc32: m8xx watchdog update · fb64c244
      Marcelo Tosatti authored
      This updates m8xx_wdt as follows:
      1) Remove now obsolete fpos check in the write() function. The driver is
      currently non functional due to this bug.
      2) Use in/out macros for register access.
      3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT
      for keep-alive trigger (which is responsible for servicing the watchdog
      until an userspace application takes over). For instance Cyclades PRxK
      boards (MPC 855T based) have a non-functional internal RTC/PIT unit.
      Behaviour for boards with RTC/PIT is unchaged.
      4) The last change required moving the RTCSC register setting code
      to a weak function which can be overriden by board specific files.
      Otherwise the timer init code trashes the register making it impossible
      for m8xx_wdt to detect the situation.

      ppc: Adapt to asm-powerpc/irq.h irq_canonicalize changes · 35d81a4b
      Paul Mackerras authored
      Now instead of having a ppc_md function, we just have a variable
      which says whether to do the i8259 irq canonicalization or not,
      and set that variable on the platforms that need that.  It looks
      to me that radstone_ppc7d was trying to use irq canonicalization
      for something else in a broken kind of way - it will need to be
      fixed properly.

      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!
