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.
