[NETFILTER]: nf_conntrack_ipv4: fix module parameter compatibility
Some users do "modprobe ip_conntrack hashsize=...". Since we have the
module aliases this loads nf_conntrack_ipv4 and nf_conntrack, the
hashsize parameter is unknown for nf_conntrack_ipv4 however and makes
it fail.
Allow to specify hashsize= for both nf_conntrack and nf_conntrack_ipv4.
Note: the nf_conntrack message in the ringbuffer will display an
incorrect hashsize since nf_conntrack is first pulled in as a
dependency and calculates the size itself, then it gets changed
through a call to nf_conntrack_set_hashsize().

tty: fix logic change introduced by wait_event_interruptible_timeout()
Commit
5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8 introduced a subtle logic
change in tty_wait_until_sent(). The original version would only error out
of the 'do { ... } while (timeout)' loop if signal_pending() evaluated to
true; a timeout or break due to an empty buffer would fall out of the loop
and into the tty->driver->wait_until_sent handling. The current
implementation will error out on either a pending signal or an empty
buffer, falling through to the tty->driver->wait_until_sent handling only
on a timeout.
The ->wait_until_sent() will not be reached if the buffer empties before
timeout jiffies have elapsed. This behavior differs from that prior to commit
5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8.
I turned this up while using a little serial download utility to bootstrap an
ARM-based eval board. The util worked fine on 2.6.22.x, but consistently
failed on 2.6.23.x. Once I'd determined that, I narrowed things down with git
bisect, and found the above difference in logic in tty_wait_until_sent() by
inspection.
This change reverts the logic flow in tty_wait_until_sent() to match that
prior to the aforementioned commit.

lib: proportion: fix underflow in prop_norm_percpu()
Zhe Jiang noticed that its possible to underflow pl->events in
prop_norm_percpu() when the value returned by percpu_counter_read() is less
than the error on that read and the period delay > 1. In that case half might
not trigger the batch increment and the value will be identical on the next
iteration, causing the same half to be subtracted again and again.
Fix this by rewriting the division as a single subtraction instead of a
subtraction loop and using percpu_counter_sum() when the value returned by
percpu_counter_read() is smaller than the error.
The latter is still needed if we want pl->events to shrink properly in the
error region.

3c574 and 3c589 endianness fixes (.24?)
Both store MAC address in CIS; there's no decoder for that
type (0x88) so the drivers work with raw data. It is
byteswapped, so ntohs() works for little-endian, but for
big-endian it's wrong. ntohs(le16_to_cpu()) does the
right thing on both (and always expands to swab16()).

dm crypt: use bio_add_page
Fix possible max_phys_segments violation in cloned dm-crypt bio.
In write operation dm-crypt needs to allocate new bio request
and run crypto operation on this clone. Cloned request has always
the same size, but number of physical segments can be increased
and violate max_phys_segments restriction.
This can lead to data corruption and serious hardware malfunction.
This was observed when using XFS over dm-crypt and at least
two HBA controller drivers (arcmsr, cciss) recently.
Fix it by using bio_add_page() call (which tests for other
restrictions too) instead of constructing own biovec.

dm: table detect io beyond device
This patch fixes a panic on shrinking a DM device if there is
outstanding I/O to the part of the device that is being removed.
(Normally this doesn't happen - a filesystem would be resized first,
for example.)
The bug is that __clone_and_map() assumes dm_table_find_target()
always returns a valid pointer. It may fail if a bio arrives from the
block layer but its target sector is no longer included in the DM
btree.
This patch appends an empty entry to table->targets[] which will
be returned by a lookup beyond the end of the device.
After calling dm_table_find_target(), __clone_and_map() and target_message()
check for this condition using
dm_target_is_valid().

debug: add end-of-oops marker
Right now it's nearly impossible for parsers that collect kernel crashes
from logs or emails (such as www.kerneloops.org) to detect the
end-of-oops condition. In addition, it's not currently possible to
detect whether or not 2 oopses that look alike are actually the same
oops reported twice, or are truly two unique oopses.
This patch adds an end-of-oops marker, and makes the end marker include
a very simple 64-bit random ID to be able to detect duplicate reports.
Normally, this ID is calculated as a late_initcall() (in the hope that
at that time there is enough entropy to get a unique enough ID); however
for early oopses the oops_exit() function needs to generate the ID on
the fly.
We do this all at the _end_ of an oops printout, so this does not impact
our ability to get the most important portions of a crash out to the
console first.
[ Sidenote: the already existing oopses-since-bootup counter we print
during crashes serves as the differentiator between multiple oopses
that trigger during the same bootup. ]
Tested on 32-bit and 64-bit x86. Artificially injected very early
crashes as well, as expected they result in this constant ID after
multiple bootups:

because the random pools are still all zero. But it all still works
fine and causes no additional problems (which is the main goal of
instrumentation code).

sched: rt: account the cpu time during the tick
Realtime tasks would not account their runtime during ticks. Which would lead
to:
struct sched_param param = { .sched_priority = 10 };
pthread_setschedparam(pthread_self(), SCHED_FIFO, ¶m);
while (1) ;

[SPARC64]: Fix OOPS in dma_sync_*_for_device()
I included these operations vector cases for situations
where we never need to do anything, the entries aren't
filled in by any implementation, so we OOPS trying to
invoke NULL pointer functions.
Really make them NOPs, to fix the bug.

[NET]: Correct two mistaken skb_reset_mac_header() conversions.
This operation helper abstracts:
skb->mac_header = skb->data;
but it was done in two more places which were actually:
skb->mac_header = skb->network_header;
and those are corrected here.

[XFRM]: Audit function arguments misordered
In several places the arguments to the xfrm_audit_start() function are
in the wrong order resulting in incorrect user information being
reported. This patch corrects this by pacing the arguments in the
correct order.

[IPSEC]: Avoid undefined shift operation when testing algorithm ID
The aalgos/ealgos fields are only 32 bits wide. However, af_key tries
to test them with the expression 1 << id where id can be as large as
253. This produces different behaviour on different architectures.
The following patch explicitly checks whether ID is greater than 31
and fails the check if that's the case.
We cannot easily extend the mask to be longer than 32 bits due to
exposure to user-space. Besides, this whole interface is obsolete
anyway in favour of the xfrm_user interface which doesn't use this
bit mask in templates (well not within the kernel anyway).
