      [MIPS] Rewrite all the assembler interrupt handlers to C. · e4ac58af
      Ralf Baechle authored
      Saves like 1,600 lines of code, is way easier to debug, compilers
      frequently do a better job than the cut and paste type of handlers many
      boards had.  And finally having all the stuff done in a single place
      also means alot of bug potencial for the MT ASE is gone.
      The only surviving handler in assembler is the DECstation one; I hope
      Maciej will rewrite it.

      [PATCH] unify PFN_* macros · 22a9835c
      Dave Hansen authored
      Just about every architecture defines some macros to do operations on pfns.
       They're all virtually identical.  This patch consolidates all of them.
      One minor glitch is that at least i386 uses them in a very skeletal header
      file.  To keep away from #include dependency hell, I stuck the new
      definitions in a new, isolated header.
      Of all of the implementations, sh64 is the only one that varied by a bit.
      It used some masks to ensure that any sign-extension got ripped away before
      the arithmetic is done.  This has been posted to that sh64 maintainers and
      the development list.
      Compiles on x86, x86_64, ia64 and ppc64.

      [PATCH] more for_each_cpu() conversions · 394e3902
      Andrew Morton authored
      When we stop allocating percpu memory for not-possible CPUs we must not touch
      the percpu data for not-possible CPUs at all.  The correct way of doing this
      is to test cpu_possible() or to use for_each_cpu().
      This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
      few instances of this bug, if any.  But the patch converts lots of open-coded
      test to use the preferred helper macros.

      [MIPS] SMP: Fix initialization order bug. · 9b6695a8
      Ralf Baechle authored
      A recent change requires cpu_possible_map to be initialized before
      smp_sched_init() but most MIPS platforms were initializing their
      processors in the prom_prepare_cpus callback of smp_prepare_cpus.  The
      simple fix of calling prom_prepare_cpus from one of the earlier SMP
      initialization hooks doesn't work well either since IPIs may require
      init_IRQ() to have completed, so bit the bullet and split
      prom_prepare_cpus into two initialization functions, plat_smp_setup
      which is called early from setup_arch and plat_prepare_cpus called where
      prom_prepare_cpus used to be called.

      [PATCH] fix missing includes · 4e57b681
      Tim Schmielau authored
      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.

      [PATCH] remove non-DISCONTIG use of pgdat->node_mem_map · 408fde81
      Dave Hansen authored
      This patch effectively eliminates direct use of pgdat->node_mem_map outside
      of the DISCONTIG code.  On a flat memory system, these fields aren't
      currently used, neither are they on a sparsemem system.
      There was also a node_mem_map(nid) macro on many architectures.  Its use
      along with the use of ->node_mem_map itself was not consistent.  It has
      been removed in favor of two new, more explicit, arch-independent macros:
      	pgdat_page_nr(pgdat, pagenr)
      	nid_page_nr(nid, pagenr)
      I called them "pgdat" and "nid" because we overload the term "node" to mean
      "NUMA node", "DISCONTIG node" or "pg_data_t" in very confusing ways.  I
      believe the newer names are much clearer.
      These macros can be overridden in the sparsemem case with a theoretically
      slower operation using node_start_pfn and pfn_to_page(), instead.  We could
      make this the only behavior if people want, but I don't want to change too
      much at once.  One thing at a time.
      This patch removes more code than it adds.
      Compile tested on alpha, alpha discontig, arm, arm-discontig, i386, i386
      generic, NUMAQ, Summit, ppc64, ppc64 discontig, and x86_64.  Full list
      here: http://sr71.net/patches/2.6.12/2.6.12-rc1-mhp2/configs/
      Boot tested on NUMAQ, x86 SMP and ppc64 power4/5 LPARs.

      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!
