This patch makes pppol2tp_xmit call skb_cow_head so that we don't modify
cloned skb data. It also gets rid of skb2 we only need to preserve the
original skb for congestion notification, which is only applicable for
ppp_async and ppp_sync.
The other semantic change made here is the removal of socket accounting
for data tranmitted out of pppol2tp_xmit. The original code leaked any
existing socket skb accounting. We could fix this by dropping the
original skb owner. However, this is undesirable as the packet has not
physically left the host yet.
In fact, all other tunnels in the kernel do not account skb's passing
through to their own socket. In partciular, ESP over UDP does not do
so and it is the closest tunnel type to PPPoL2TP. So this patch simply
removes the socket accounting in pppol2tp_xmit. The accounting still
applies to control packets of course.
I've also added a reminder that the outgoing checksum here doesn't work.
I suppose existing deployments don't actually enable checksums.

The following patch fixes the handling of netlink packets containing
multiple messages.
As exposed during netfilter workshop, nfnetlink_log was overwritten the
message type of the last message (setting it to MSG_DONE) in a multipart
packet. The consequence was libnfnetlink to ignore the last message in the
packet.
The following patch adds a supplementary message (with type MSG_DONE) af

Emil Medve points out that this documentation file uses CRLF line
endings, which means that if you use
[core]
autocrlf=input
(which makes sense if you ever develop under Windows, for example, or if
you use other broken tools) in your git config, git will always complain
about the file being dirty.
This removes the bogus DOS line endings, and removes whitespace at the
end of line.

wakeup.S looks at the video mode number from the setup header and
looks to see if it is a VESA mode. Unfortunately, the decoding is
done incorrectly and it will attempt to frob the VESA BIOS for any
mode number 0x0200 or larger. Correct this, and remove a bunch of #if

Additional cleanup for debug boards on H2/P2/H3/H4: move the init
code that's not board-specific into a new file where it can be easily
shared between all the different boards (avoiding code duplication,
and making it easier to support more devices). Make H4 use that.
This should be easy to drop in to the OMAP1 boards using these debug
cards; the only difference seems to be that the p2 does an extra reset
of the smc using the fpga (probably all boards could do that, if it's
necessary) and doesn't use the gpio mux or request APIs.

GPMC updates:
- bugfixes: wrong/missing flags, omitted write, wrong test
- don't map memory segments starting at zero
- improve debug messaging
- export gpmc_get_fclk_perio]d() since it's needed to calc timings
- expect gpmc_cs_set_timings() caller to have initialized sync vs async
Note that this API is glitchy; likely the best fix would be to add
a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that
holds one key aspect of the GPMC timings (the gpmc_fclk divisor,
and sync vs. async == whether that divisor matters).

This patch includes a whole batch of smallish cleanups for
drivers/mtd/physmap_of.c.
- A bunch of uneeded #includes are removed
- We switch to the modern linux/of.h etc. in place of
asm/prom.h
- Use some helper macros to avoid some ugly inline #ifdefs
- A few lines of unreachable code are removed
- A number of indentation / line-wrapping fixes
- More consistent use of kernel idioms such as if (!p) instead
of if (p == NULL)
- Clarify some printk()s and other informative strings.
- parse_obsolete_partitions() now returns 0 if no partition
information is found, instead of returning -ENOENT which the caller
had to handle specially.
- (the big one) Despite the name, this driver really has
nothing to do with drivers/mtd/physmap.c. The fact that the flash
chips must be physically direct mapped is a constrant, but doesn't
really say anything about the actual purpose of this driver, which is
to instantiate MTD devices based on information from the device tree.
Therefore the physmap name is replaced everywhere within the file with
"of_flash". The file itself and the Kconfig option is not renamed for
now (so that the diff is actually a diff). That can come later.

The new xlog_recover_do_reg_buffer checks call be16_to_cpu on di_gen which
is a 32bit value so sparse rightly complains. Fortunately the warning is
harmless because we don't care for the value, but only whether it's
non-NULL. Due to that fact we can simply kill the endian swaps on this and
the previous di_mode check entirely.

it's getting garbage for *item, which subsequently causes an explosion.

When using rt_mutex, a NULL pointer dereference is occurred at
enqueue_task_rt. Here is a scenario;
1) there are two threads, the thread A is fair_sched_class and
thread B is rt_sched_class.
2) Thread A is boosted up to rt_sched_class, because the thread A
has a rt_mutex lock and the thread B is waiting the lock.
3) At this time, when thread A create a new thread C, the thread
C has a rt_sched_class.
4) When doing wake_up_new_task() for the thread C, the priority
of the thread C is out of the RT priority range, because the
normal priority of thread A is not the RT priority. It makes
data corruption by overflowing the rt_prio_array.
The new thread C should be fair_sched_class.
The new thread should be valid scheduler class before queuing.
This patch fixes to set the suitable scheduler class.
