Reduce radix tree node memory usage by about a factor of 4 for small files
(< 64K). There are pointer traversal and memory usage costs for large
files with dense pagecache.

The ability to have height 0 radix trees (a direct pointer to the data item
rather than going through a full node->slot) quietly disappeared with
old-2.6-bkcvs commit ffee171812d51652f9ba284302d9e5c5cc14bdfd. On 64-bit
machines this causes nearly 600 bytes to be used for every <= 4K file in
pagecache.
Re-introduce this feature, root tags stored in spare ->gfp_mask bits.
Simplify radix_tree_delete's complex tag clearing arrangement (which would
become even more complex) by just falling back to tag clearing functions
(the pagecache radix-tree never uses this path anyway, so the icache
savings will mean it's actually a speedup).
On my 4GB G5, this saves 8MB RAM per kernel kernel source+object tree in
pagecache.
Pagecache lookup, insertion, and removal speed for small files will also be
improved.
This makes RCU radix tree harder, but it's worth it.

Modify the gen_pool allocator (lib/genalloc.c) to utilize a bitmap scheme
instead of the buddy scheme. The purpose of this change is to eliminate
the touching of the actual memory being allocated.
Since the change modifies the interface, a change to the uncached allocator
(arch/ia64/kernel/uncached.c) is also required.
Both Andrey Volkov and Jes Sorenson have expressed a desire that the
gen_pool allocator not write to the memory being managed. See the
following:

Rework the swsusp's memory shrinker in the following way:
- Simplify balance_pgdat() by removing all of the swsusp-related code
from it.
- Make shrink_all_memory() use shrink_slab() and a new function
shrink_all_zones() which calls shrink_active_list() and
shrink_inactive_list() directly for each zone in a way that's optimized
for suspend.
In shrink_all_memory() we try to free exactly as many pages as the caller
asks for, preferably in one shot, starting from easier targets. If slab
caches are huge, they are most likely to have enough pages to reclaim.
The inactive lists are next (the zones with more inactive pages go first)
etc.
Each time shrink_all_memory() attempts to shrink the active and inactive
lists for each zone in 5 passes. In the first pass, only the inactive
lists are taken into consideration. In the next two passes the active
lists are also shrunk, but mapped pages are not reclaimed. In the last
two passes the active and inactive lists are shrunk and mapped pages are
reclaimed as well. The aim of this is to alter the reclaim logic to choose
the best pages to keep on resume and improve the responsiveness of the
resumed system.

The last ifdef addition hit the ugliness treshold on this functions, so:
- rename the variable i to nr_pages so it's somewhat descriptive
- remove the addr variable and do the page_address call at the very end
- instead of ifdef'ing the whole alloc_pages_node call just make the
__GFP_COMP addition to flags conditional
- rewrite the __GFP_COMP comment to make sense

Current hugetlb strict accounting for shared mapping always assume mapping
starts at zero file offset and reserves pages between zero and size of the
file. This assumption often reserves (or lock down) a lot more pages then
necessary if application maps at none zero file offset. libhugetlbfs is
one example that requires proper reservation on shared mapping starts at
none zero offset.
This patch extends the reservation and hugetlb strict accounting to support
any arbitrary pair of (offset, len), resulting a much more robust and
accurate scheme. More importantly, it won't lock down any hugetlb pages
outside file mapping.

Reserve space in the swap disk header for a LABEL and UUID to be specified.
This has been possible with util-linux-2.12b (via e2fsprogs 1.36
libblkid), and is used by at least FC3 and later. The kernel doesn't
really care about this, but the space shouldn't accidentally be used by
something else either.
Also make the on-disk structures be fixed-size types, instead of "int",
though I don't know of any architecture in use where an "int" isn't the
same size as a "__u32" (all current kernel arches have it as "unsigned
int").

This patch adds panic_on_oom sysctl under sys.vm.
When sysctl vm.panic_on_oom = 1, the kernel panics intead of killing rogue
processes. And if vm.panic_on_oom is 0 the kernel will do oom_kill() in
the same way as it does today. Of course, the default value is 0 and only
root can modifies it.
In general, oom_killer works well and kill rogue processes. So the whole
system can survive. But there are environments where panic is preferable
rather than kill some processes.

We have architectures where the size of page_to_pfn and pfn_to_page are
significant enough to overall image size that they wish to push them out of
line. However, in the process we have grown a second copy of the
implementation of each of these routines for each memory model. Share the
implmentation exposing it either inline or out-of-line as required.

In current code, zonelist is considered to be build once, no modification.
But MemoryHotplug can add new zone/pgdat. It must be updated.
This patch modifies build_all_zonelists(). By this, build_all_zonelist() can
reconfig pgdat's zonelists.
To update them safety, this patch use stop_machine_run(). Other cpus don't
touch among updating them by using it.
In old version (V2 of node hotadd), kernel updated them after zone
initialization. But present_page of its new zone is still 0, because
online_page() is not called yet at this time. Build_zonelists() checks
present_pages to find present zone. It was too early. So, I changed it after
online_pages().

It is better to redo the complete fault if do_swap_page() finds that the
page is not in PageSwapCache() because the page migration code may have
replaced the swap pte already with a pte pointing to valid memory.
do_swap_page() may interpret an invalid swap entry without this patch
because we do not reload the pte if we are looping back. The page
migration code may already have reused the swap entry referenced by our
local swp_entry.

The buddy allocator has a requirement that boundaries between contigious
zones occur aligned with the the MAX_ORDER ranges. Where they do not we
will incorrectly merge pages cross zone boundaries. This can lead to pages
from the wrong zone being handed out.
Originally the buddy allocator would check that buddies were in the same
zone by referencing the zone start and end page frame numbers. This was
removed as it became very expensive and the buddy allocator already made
the assumption that zones boundaries were aligned.
It is clear that not all configurations and architectures are honouring
this alignment requirement. Therefore it seems safest to reintroduce
support for non-aligned zone boundaries. This patch introduces a new check
when considering a page a buddy it compares the zone_table index for the
two pages and refuses to merge the pages where they do not match. The
zone_table index is unique for each node/zone combination when
FLATMEM/DISCONTIGMEM is enabled and for each section/zone combination when
SPARSEMEM is enabled (a SPARSEMEM section is at least a MAX_ORDER size).

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs. This is inefficient and
possibly buggy.
We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.
This patch replaces for_each_cpu with for_each_possible_cpu.

Give the statfs superblock operation a dentry pointer rather than a superblock
pointer.
This complements the get_sb() patch. That reduced the significance of
sb->s_root, allowing NFS to place a fake root there. However, NFS does
require a dentry to use as a target for the statfs operation. This permits
the root in the vfsmount to be used instead.
linux/mount.h has been added where necessary to make allyesconfig build
successfully.
Interest has also been expressed for use with the FUSE and XFS filesystems.

Extend the get_sb() filesystem operation to take an extra argument that
permits the VFS to pass in the target vfsmount that defines the mountpoint.
The filesystem is then required to manually set the superblock and root dentry
pointers. For most filesystems, this should be done with simple_set_mnt()
which will set the superblock pointer and then set the root dentry to the
superblock's s_root (as per the old default behaviour).
The get_sb() op now returns an integer as there's now no need to return the
superblock pointer.
This patch permits a superblock to be implicitly shared amongst several mount
points, such as can be done with NFS to avoid potential inode aliasing. In
such a case, simple_set_mnt() would not be called, and instead the mnt_root
and mnt_sb would be set directly.
The patch also makes the following changes:
(*) the get_sb_*() convenience functions in the core kernel now take a vfsmount
pointer argument and return an integer, so most filesystems have to change
very little.
(*) If one of the convenience function is not used, then get_sb() should
normally call simple_set_mnt() to instantiate the vfsmount. This will
always return 0, and so can be tail-called from get_sb().
(*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the
dcache upon superblock destruction rather than shrink_dcache_anon().
This is required because the superblock may now have multiple trees that
aren't actually bound to s_root, but that still need to be cleaned up. The
currently called functions assume that the whole tree is rooted at s_root,
and that anonymous dentries are not the roots of trees which results in
dentries being left unculled.
However, with the way NFS superblock sharing are currently set to be
implemented, these assumptions are violated: the root of the filesystem is
simply a dummy dentry and inode (the real inode for '/' may well be
inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries
with child trees.
[*] Anonymous until discovered from another tree.
(*) The documentation has been adjusted, including the additional bit of
changing ext2_* into foo_* in the documentation.

quirk to make AER PCI-E extended capability visible) now makes sure that
this cap will be available to pci_find_ext_capability().

Eric Sesterhenn found that pci200syn initialization lacks return
statement in ioremap() error path (coverity bug id #195). It looks
like more WAN drivers have problems with ioremap().

David Boggs noticed that register_hdlc_device() no longer needs
to call dev_alloc_name() as it's called by register_netdev().
register_hdlc_device() is currently equivalent to register_netdev().
hdlc_setup() is now EXPORTed as per David's request.

Ah the resounding clang of a subtle hint ;)

- Return 8390.c to the old way of handling short packets (which is also
faster)
- Remove the skb_padto from orinoco. This got left in when the padding bad
write patch was added and is actually not needed. This is fixing a merge
error way back when.
- Wavelan can also use the stack based buffer trick if you want

hi,
coverity found (bug id #225) that we might call free_netdev()
with NULL argument, when alloc_trdev() fails. This patch
changes the goto, so we dont call free_netdev() for
dev == NULL.

hi,
this is another array overrun spotted by coverity (#id 507)
we should check the index against array size before using it.
Not sure why the driver doesnt use ARRAY_SIZE instead of its
own macro.

hi,
coverity choked at this check (id #223), assuming that
skb might be NULL and used anyways later. Since
start_hard_xmit() always gets called with a valid
skb, the check is useless and this patch removes it.
