      [PATCH] Clean up and refactor i386 sub-architecture setup · e75eac33
      Jeremy Fitzhardinge authored
      Clean up and refactor i386 sub-architecture setup.
      
      This change moves all the code from the
      asm-i386/mach-*/setup_arch_pre/post.h headers, into
      arch/i386/mach-*/setup.c.  mach-*/setup_arch_pre.h is renamed to
      setup_arch.h, and contains only things which should be in header files.  It
      is purely code-motion; there should be no functional changes at all.
      
      Several functions in arch/i386/kernel/setup.c needed to be made non-static
      so that they're visible to the code in mach-*/setup.c.  asm-i386/setup.h is
      used to hold the prototypes for these functions.

      [PATCH] Allow migration of mlocked pages · e6a1530d
      Christoph Lameter authored
      Hugh clarified the role of VM_LOCKED.  So we can now implement page
      migration for mlocked pages.
      
      Allow the migration of mlocked pages.  This means that try_to_unmap must
      unmap mlocked pages in the migration case.

      [PATCH] page migration: Support a vma migration function · 7b2259b3
      Christoph Lameter authored
      Hooks for calling vma specific migration functions
      
      With this patch a vma may define a vma->vm_ops->migrate function.  That
      function may perform page migration on its own (some vmas may not contain page
      structs and therefore cannot be handled by regular page migration.  Pages in a
      vma may require special preparatory treatment before migration is possible
      etc) .  Only mmap_sem is held when the migration function is called.  The
      migrate() function gets passed two sets of nodemasks describing the source and
      the target of the migration.  The flags parameter either contains
      
      MPOL_MF_MOVE	which means that only pages used exclusively by
      		the specified mm should be moved
      
      or
      
      MPOL_MF_MOVE_ALL which means that pages shared with other processes
      		should also be moved.
      
      The migration function returns 0 on success or an error condition.  An error
      condition will prevent regular page migration from occurring.
      
      On its own this patch cannot be included since there are no users for this
      functionality.  But it seems that the uncached allocator will need this
      functionality at some point.

      [PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHM · 68402ddc
      Christoph Lameter authored
      Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
      VM_SHM.
      
      remap_pfn_range() already sets VM_IO.  There is no need to set VM_SHM since
      it does nothing.  VM_LOCKED is of no use since the remap_pfn_range does not
      place pages on the LRU.  The pages are therefore never subject to swap
      anyways.  Remove all the vm_flags settings before calling remap_pfn_range.
      
      After removing all the vm_flag settings no use of VM_SHM is left.  Drop it.

      [PATCH] AOP_TRUNCATED_PAGE victims in read_pages() belong in the LRU · 9f1a3cfc
      Zach Brown authored
      AOP_TRUNCATED_PAGE victims in read_pages() belong in the LRU
      
      Nick Piggin rightly pointed out that the introduction of AOP_TRUNCATED_PAGE
      to read_pages() was wrong to leave A_T_P victim pages in the page cache but
      not put them in the LRU.  Failing to do so hid them from the VM.
      
      A_T_P just means that the aop method unlocked the page rather than
      performing IO.  It would be very rare that the page was truncated between
      the unlock and testing A_T_P.  So we leave the pages in the LRU for likely
      reuse soon rather than backing them back out of the page cache.  We do this
      by matching the behaviour before the A_T_P introduction which added pages
      to the LRU regardless of what ->readpage() did.
      
      This doesn't include the unrelated cleanup in Nick's initial fix which
      changed read_pages() to return void to match its only caller's behaviour of
      ignoring errors.

      It's going away.
      
      I wonder if this code really meant to iterate across not-present, not-online
      CPUs.

      Revert "[PATCH] usb: drivers/usb/core/devio.c dereferences a userspace pointer" · 83626b01
      Linus Torvalds authored
      This reverts commit 786dc1d3.
      
      As Al so eloquently points out, the patch is crap. The old code was fine,
      the new code was bogus.
      
      It never dereferenced a user pointer, the "->" operator was to an array
      member, which gives the _address_ of the member (in user space), not an
      actual dereference at all.
