      convert ill defined log2() to ilog2() · e57aa839
      Fengguang Wu authored
      It's *wrong* to have
      			#define log2(n) ffz(~(n))
      It should be *reversed*:
      			#define log2(n) flz(~(n))
      or
      			#define log2(n) fls(n)
      or just use
      			ilog2(n) defined in linux/log2.h.
      
      This patch follows the last solution, recommended by Andrew Morton.

      [AGPGART] Allow drm-populated agp memory types · a030ce44
      Thomas Hellstrom authored
      This patch allows drm to populate an agpgart structure with pages of its own.
      It's needed for the new drm memory manager which dynamically flips pages in and out of AGP.
      
      The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is
      currently the only one supporting the new memory manager.
      
      Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver.
      
      AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected
      to do that, as well as taking care of cache- and tlb flushing when needed.
      
      It's not possible to request these types from user space using agpgart ioctls.
      
      The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

      [PATCH] AGP performance fixes · 88d51967
      Alan Hourihane authored
      AGP allocation/deallocation is suffering major performance issues due to
      the nature of global_flush_tlb() being called on every change_page_attr()
      call.
      
      For small allocations this isn't really seen, but when you start allocating
      50000 pages of AGP space, for say, texture memory, then things can take
      seconds to complete.
      
      In some cases the situation is doubled or even quadrupled in the time due
      to SMP, or a deallocation, then a new reallocation.  I've had a case of
      upto 20 seconds wait time to deallocate and reallocate AGP space.
      
      This patch fixes the problem by making it the caller's responsibility to
      call global_flush_tlb(), and so removes it from every instance of mapping a
      page into AGP space until the time that all change_page_attr() changes are
      done.

      [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] AGP fix for Xen VMM · 07eee78e
      Keir Fraser authored
      When Linux is running on the Xen virtual machine monitor, physical
      addresses are virtualised and cannot be directly referenced by the AGP
      GART.  This patch fixes the GART driver for Xen by adding a layer of
      abstraction between physical addresses and 'GART addresses'.
      
      Architecture-specific functions are also defined for allocating and freeing
      the GATT.  Xen requires this to ensure that table really is contiguous from
      the point of view of the GART.
      
      These extra interface functions are defined as 'no-ops' for all existing
      architectures that use the GART driver.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds authored
      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!
