[PATCH] audit: rename AUDIT_SE_* constants
This patch renames some audit constant definitions and adds

avoids ambiguity with respect to the new definitions.

[PATCH] add rule filterkey
Add support for a rule key, which can be used to tie audit records to audit
rules. This is useful when a watched file is accessed through a link or
symlink, as well as for general audit log analysis.
Because this patch uses a string key instead of an integer key, there is a bit
of extra overhead to do the kstrdup() when a rule fires. However, we're also
allocating memory for the audit record buffer, so it's probably not that
significant. I went ahead with a string key because it seems more
user-friendly.
Note that the user must ensure that filterkeys are unique. The kernel only
checks for duplicate rules.

[IPV6]: Added GSO support for TCPv6
This patch adds GSO support for IPv6 and TCPv6. This is based on a patch
by Ananda Raju <Ananda.Raju@neterion.com>. His original description is:
This patch enables TSO over IPv6. Currently Linux network stacks
restricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from
"dev->features". This patch will remove this restriction.
This patch will introduce a new flag NETIF_F_TSO6 which will be used
to check whether device supports TSO over IPv6. If device support TSO
over IPv6 then we don't clear of NETIF_F_TSO and which will make the
TCP layer to create TSO packets. Any device supporting TSO over IPv6
will set NETIF_F_TSO6 flag in "dev->features" along with NETIF_F_TSO.
In case when user disables TSO using ethtool, NETIF_F_TSO will get
cleared from "dev->features". So even if we have NETIF_F_TSO6 we don't
get TSO packets created by TCP layer.
SKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet.
SKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature.
UFO is supported over IPv6 also
The following table shows there is significant improvement in
throughput with normal frames and CPU usage for both normal and jumbo.

The only catch is that whoever uses this must provide a GSO implementation

In the typical v2/v3 case the only new filehandles used as arguments to
operations are filehandles taken directly off the wire, which don't get
dentries until fh_verify() is called.
But in v4 the filehandles that are arguments to operations were often created
by previous operations (putrootfh, lookup, etc.) using fh_compose, which sets
the dentry in the filehandle without calling nfsd_setuser().
This also means that, for example, if filesystem B is mounted on filesystem A,
and filesystem A is exported without root-squashing, then a client can bypass
the rootsquashing on B using a compound that starts at a filehandle in A,
crosses into B using lookups, and then does stuff in B.

[PATCH] knfsd: ignore ref_fh when crossing a mountpoint
nfsd tries to return to a client the same sort of filehandle as was used by
the client. This removes some filehandle aliasing issues and means that a
server upgrade followed by a downgrade will not confused clients not restarted
during that time.
However when crossing a mountpoint, the filehandle used for one filesystem
doesn't provide any useful information on what sort of filehandle should be
used on the other, and can provide misleading information. So if the
reference filehandle is on a different filesystem to the one being generated,
ignore it.

[PATCH] knfsd: remove noise about filehandle being uptodate
There is a perfectly valid situation where fh_update gets called on an already
uptodate filehandle - in nfsd_create_v3 where a CREATE_UNCHECKED finds an
existing file and wants to just set the size.
We could possible optimise out the call in that case, but the only harm
involved is that fh_update prints a warning, so it is easier to remove the
warning.

determine the ID number for a mem_ctl_info structure. Then modify
edac_mc_add_mc() so that the caller specifies the ID number for the new
mem_ctl_info structure. Platform-specific code should be able to assign the
ID numbers in a platform-specific manner. For instance, on Opteron it makes
sense to have the ID of the mem_ctl_info structure match the ID of the node
that the memory controller belongs to.

[PATCH] cond_resched() fix
Fix a bug identified by Zou Nan hai <nanhai.zou@intel.com>:
If the system is in state SYSTEM_BOOTING, and need_resched() is true,
cond_resched() returns true even though it didn't reschedule. Consequently
need_resched() remains true and JBD locks up.
Fix that by teaching cond_resched() to only return true if it really did call
schedule().
cond_resched_lock() and cond_resched_softirq() have a problem too. If we're
in SYSTEM_BOOTING state and need_resched() is true, these functions will drop
the lock and will then try to call schedule(), but the SYSTEM_BOOTING state
will prevent schedule() from being called. So on return, need_resched() will
still be true, but cond_resched_lock() has to return 1 to tell the caller that
the lock was dropped. The caller will probably lock up.
Bottom line: if these functions dropped the lock, they _must_ call schedule()
to clear need_resched(). Make it so.
Also, uninline __cond_resched(). It's largeish, and slowpath.

[PATCH] uml: unregister useless console when it's not needed
-mm in combination with an FC5 init started dying with 'stderr=1' because init
didn't like the lack of /dev/console and exited. The problem was that the
stderr console, which is intended to dump printk output to the terminal before
the regular console is initialized, isn't a tty, and so can't make
/dev/console operational.
However, since it is registered first, the normal console, when it is
registered, doesn't become the preferred console, and isn't attached to
/dev/console. Thus, /dev/console is never operational.
This patch makes the stderr console unregister itself in an initcall, which is
late enough that the normal console is registered. When that happens, the
normal console will become the preferred console and will be able to run
/dev/console.
