 Merged

-lpp2.patch

 Folded into lpp.patch - hugetlb fixes

+lpp-update.patch

 More hugetlb fixes from Rohit.

+pf_nowarn.patch

 Prevent some `page allocation failure' warnings which aren't supposed
 to come out.

+jeremy.patch

 Spel Jermy's naim wright

-segq.patch

 SEGQ had an interaction with the dirty memory management.  This interaction
 was the source of Badari's IO bandwidth regression.  Removed until I have
 time to poke at it.

+wake-speedup.patch

 Badari's pagecache writeout is back up to 270 megs/sec.  The CPUs are pegged
 and the hottest functions are 

  5348 __wake_up                                111.4167
  6954 unlock_page                               72.4375
187676 generic_file_write_nolock                 71.9617
  9577 __scsi_end_request                        54.4148

 I cannot reproduce these profiles with mortal numbers of hard disks, but
 the wakeup code can be sped up heaps.

 The patch implements a new wait/wakeup mechanism which removes wait_queues
 from wait_queue_head's within __wake_up(), rather than within the woken
 process.

+buddyinfo.patch

 /proc/buddyinfo - stats on free page fragmentation.

+free_area.patch

 Nail another gratuitous typedef

+radix_tree_gang_lookup.patch

 Multipage pagecache scan and lookup.

+truncate_inode_pages.patch

 Redo the truncate/invalidate code to use gang lookups.
