2c6607c611 net: add POLLPRI to sock_def_readable()
Leonardo Chiquitto found poll() could block forever on tcp sockets and
Urgent data was received, if the event flag only contains POLLPRI.

He did a bisection and found commit 4938d7e023 (poll: avoid extra
wakeups in select/poll) was the source of the problem.

Problem is TCP sockets use standard sock_def_readable() function for
their sk_data_ready() handler, and sock_def_readable() doesnt signal
POLLPRI.

Only TCP is affected by the problem. Adding POLLPRI to the list of flags
might trigger unnecessary schedules, but URGENT handling is such a
seldom used feature this seems a good compromise.

Thanks a lot to Leonardo for providing the bisection result and a test
program as well.

8484baaa50 kernel-doc: code reorganization
Move 'main' code vs. subroutines around so that they are not so
intermixed, for better readability/understanding (relative to Perl).
It was messy to follow the primary flow of code execution with the
code being mixed.  Now the code begins with data initialization,
followed by all subroutines, then ends with the main code execution.

This is almost totally source code movement, with a few changes as
needed for forward declarations.

748103e723 drivers/video/i810/i810-i2c.c: fix i2c bus handling
These patch fix a longstanding bug in the i810 frame buffer driver.

The handling of the i2c bus is wrong: A 1 bit should not written to the
i2c, these will be done by switch the i2c to input. Driving an 1 bit
active is against the i2c spec.

An active driven of a 1 bit will result in very strange error, depending
which side is the more powerful one. In my case it depends on the
temperature of the Display-Controller-EEprom: With an cold eprom a got
the correct EDID datas, with a warm one some of the 1 bits was 0 :-(

The same bug is also in the intelfb driver in the file
drivers/video/intelfb/intelfb_i2c.c. The functions intelfb_gpio_setscl()
and intelfb_gpio_setsda() do drive the 1 bit active to the i2c bus. But
since i have no card which is used by the intelfb driver i cannot fix
it.

529ed806d4 video: Fix the HGA framebuffer driver
Resurrected some old hardware and fixed up the hgafb driver to work
again. Only tested with fbcon, since most fbdev-based software appears
to only support 12bpp and up. It does not appear that this driver has
worked for at least the entire 2.6.x series, perhaps since 2002.

Hercules graphics hardware uses packed pixels horizontally, but rows are
not linear. In other words, the pixels are not packed vertically. This
means that custom imageblit, fillrect and copyarea need to be written
specific to the hardware.

 * Removed the experimental acceleration option, since it is required
   for the hardware to work.
 * Fixed imageblit to work with fb_image's wider than 8 pixels.
 * Updated configuration text (HGA hardware is from 1984)

This code had an error handling goto to the wrong place, a misplaced

417d48274e fbdev: sh_mobile_lcdcfb: Enable 32 bpp and 24 bpp support
This patch extends the LCDC driver with 24 bpp
and 32 bpp support.

These modes have been kept disabled earlier due
to dependencies between the potential two LCDC
channels that are exported as two separate
framebuffer devices. The dependency boils down
to a byte swap register that is shared between
multiple channels.

With this patch applied all single channel LCDC
hardware can chose freely from 16, 24 and 32 bpp.
Dual channel LCDC must stick to the same setup
for both channels.

Without this patch only 16 bpp is fully supported.

3610cda53f af_unix: Avoid socket->sk NULL OOPS in stream connect security hooks.
unix_release() can asynchornously set socket->sk to NULL, and
it does so without holding the unix_state_lock() on "other"
during stream connects.

However, the reverse mapping, sk->sk_socket, is only transitioned
to NULL under the unix_state_lock().

Therefore make the security hooks follow the reverse mapping instead
of the forward mapping.

44b8288308 net_sched: pfifo_head_drop problem
commit 57dbb2d83d (sched: add head drop fifo queue)
introduced pfifo_head_drop, and broke the invariant that
sch->bstats.bytes and sch->bstats.packets are COUNTER (increasing
counters only)

This can break estimators because est_timer() handles unsigned deltas
only. A decreasing counter can then give a huge unsigned delta.

My mid term suggestion would be to change things so that
sch->bstats.bytes and sch->bstats.packets are incremented in dequeue()
only, not at enqueue() time. We also could add drop_bytes/drop_packets
and provide estimations of drop rates.

It would be more sensible anyway for very low speeds, and big bursts.
Right now, if we drop packets, they still are accounted in byte/packets
abolute counters and rate estimators.

Before this mid term change, this patch makes pfifo_head_drop behavior
similar to other qdiscs in case of drops :
Dont decrement sch->bstats.bytes and sch->bstats.packets
