i810-tco: Upgrade to version 0.05 .

Fix possible timer_alive race, add expect close support,
clean up ioctls (WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS and
WDIOC_SETOPTIONS), made i810tco_getdevice __init,
removed boot_status, removed tco_timer_read,
added support for 82801DB and 82801E chipset, general cleanup.

Add defines to pci_ids.h for 82801E and 82801DB I/O Controller Hub PCI-IDS.

Make i810_rng documentation the same as in 2.4.19

Fix free_irq() comment - it definitely is not callable
from interrupt context..

This removes the fat_search_long() in the vfat_add_entry().  This path
is already checked by the vfs layer whether file/directory exists.  So,
we don't need the fat_search_long() in vfat_add_entry().

The following is the result of created the 1000 files,

On FAT12, the current FAT driver recognizes 0xff8-0xfff as EOF, and it
writes in 0xff8 as EOF.  This is right behavior.  However, the firmware
of some MP3-Players recognize only 0xfff (standard EOF which Micorsoft
uses) as EOF.

So, we write 0xfff instead of 0xff8 as EOF, until the reason we need
values other than standard EOF is found.

From Matthew Dobson.

Leaves any functions which architectures haven't defined as undefined,
rather than using non-NUMA functions where users would expect
NUMA-functions.

This will cause compilation errors if someone tries to use an undefined
function, hopefully causing them to actually define those functions.

Also removes lingering topology-like macros that aren't being used, and
a couple typo fixes.

From Matthew Dobson <colpatch@us.ibm.com>

"This patch adds a 'simple' in-kernel topology API.  This API allows
 for three primary topology elements: CPUs, memory blocks, and nodes.
 The API allows for the discovery of which CPUs/Memory Blocks reside on
 which nodes, and vice versa.  Also implemented is a macro to get a
 bitmask of CPUs on a particular node.  This API is platform neutral."

We need this API for per-node-kswapd - without it there is no means by
which each kswapd can be bound to its node's CPUs.  And we rather need
per-node-kswapd...

The patch also uses the new API to bind each kswapd instance to its
node's CPUs

Patch from David Hansen.

Start one kswapd instance for each NUMA node.  That kswapd instance
only works against the pages which are local to that node.

We need to bind that kswapd to that node's CPU set, but the
infrastructure for this is not yet in place.

typedef eradication.

From David Hansen, Bill Irwin, Martin Bligh.

"It's easier to cat /proc/buddyinfo than to beg users to press
 shift-scrolllock on a machine millions of miles away.  Order 1 and 2
 memory allocations are common.  Memory fragmentation is a problem
 under some workloads, and this is a useful tool for helping diagnose
 these problems."

The following patch exports some information about the buddy allocator.

Each column of numbers represents the number of pages of that order
which are available.  In this case, there are 5 chunks of
2^2*PAGE_SIZE available in ZONE_DMA, and 101 chunks of 2^4*PAGE_SIZE
availble in ZONE_NORMAL, etc...  This information can give you a good
idea about how fragmented memory is and give you a clue as to how big
an area you can safely allocate.

Node 0, zone      DMA      0      4      5      4      4      3 ...
Node 0, zone   Normal      1      0      0      1    101      8 ...
Node 0, zone  HighMem      2      0      0      1      1      0 ...

GFP_NFS has been obsolete for a while now.  Kill its only remaining
user, its definition and the SLAB_NFS define too.

From Zach Brown.  Lots of places forget to initialise list_heads in
vm_area_structs, and other places then go and test the state of those
list_heads.

Plug the gaps for now, Zach is working on a broader cleanup.

move_one_page() is calling alloc_one_pte_map() while holding an atomic
kmap for the source pte's page.  But alloc_one_pte_map() can sleep in
the page allocator.

So change move_one_page() to take a peek at the destination pagetables
to work out whether the alloc_one_pte_map() will need to perform page
allocation.  If so, drop the atomic kmap and retake it after allocating
the pte.

From David Miler.

get_user_pages() needs to avoid running page_cache_get() against
PageReserved pages.  Things like video driver and audio driver
remap_page_range() mappings.

From Rohit

Creates Documentation/vm/hugetlbpage.txt

Slab currently has a policy of buffering a single spare page per slab.
We're putting that on the partially-full list, which confuses
kmem_cache_destroy().

So put it on cachep->slabs_free, which is where empty pages go.

- Dave says that lock_sock() inside locks is a popular bug.  Put a
  check there.

- Also in wait_for_completion().

- Add the text "Debug" to the warning message so people are less
  likely to think that they've oopsed.
