d420d9e32f IB/mlx4: Factor out setting WQE data segment entries
Factor code to set data segment entries out of mlx4_ib_post_send()
into set_data_seg().  This cleans up the code and lets the compiler do
a better job -- on x86_64:

add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-16 (-16)
function                                     old     new   delta

e122eaf694 [AVR32] Remove optimization of unaligned word loads
If we let unaligned word loads bypass the generic unaligned handling,
gcc may combine it with a swap.b instruction and turn it into a ldwsp
instruction, which does not work with unaligned addresses.

Revert the optimization to prevent the RNDIS driver from crashing.
Hopefully we'll figure something out later (it may be better to do the
optimization in gcc.)

a8e93ed8cb [AVR32] Make STK1000 mux settings configurable
This adds some STK1002-specific config options covering the jumper settings,
so the kernel can automatically be configured to include the relevant devices.

One of them replaces the previous internal SW2_DEFAULT setting; SPI config
is affected by two of the jumpers; and a fourth one switches between LCD and
the second Ethernet connector.  (There's more that to be done.)

9e58e1855c [AVR32] CPU frequency scaling for AT32AP
This patch enables CPU frequency scaling for AT32AP devices. This will
enable the CPU to scale between the speed of the high speed bus and
the master clock and thus save some power.

The patch also adds a parent to cpu_clk and a cpu_clk_set_rate to
enable changing the CPU clock divider in a sane way.

The driver does not check if the given rate is 0, thus resulting in a
div by 0.  I think this check should be go into the clk_set_rate
framework, and not here.

Tested on AT32AP7000/ATSTK1000.

Hardware documentation can be found in the AT32AP7000 datasheet.

c6083cd61b [AVR32] faster avr32 unaligned access
Use a more conventional implementation for unaligned access, and include
an AT32AP-specific optimization:  the CPU will handle unaligned words.

The result is always faster and smaller for 8, 16, and 32 bit values.
For 64 bit quantities, it's presumably larger.

8c027ae2dc [x86 setup] Save/restore DS around invocations of INT 10h
There exists at least one card, Trident TVGA8900CL (BIOS dated 1992/9/8)
which clobbers DS when "scrolling in an SVGA text mode of more than
800x600 pixels."  Although we are extremely unlikely to run into that
situation, it is cheap insurance to save and restore DS, and it only adds
a grand total of 50 bytes to the total output.

7ad37df02c [x86 setup] VGA: Clear the Protect bit before setting the vertical height
If the user has asked for the vertical height registers to be recomputed
by setting bit 15 in the video mode number, we do so without clearing the
Protect bit in the Vertical Retrace Register before setting the Overflow
register.  As a result, if the VGA BIOS had set the Protect bit, the
write to the Overflow register will be dropped, and bits [9:8] of the
vertical height will be left unchanged.

This is a bug imported from the assembly version of this code.  It was
pointed out by Etienne Lorrain.

5593eaa854 [x86 setup] Fix assembly constraints
Fix incorrect assembly constraints.  In particular, fix memory
constraints used inside push..pop, which can cause invalid operation
since gcc may generate %esp-relative references.

Additionally:

outl() should have "dN" not "dn".

query_mca() shouldn't listen 16/32-bit registers in an 8-bit only
context.

has_eflag(): the "mask" is only used well after both the stack pointer
and the output registers have been touched; this requires the output
registers to be earlyclobbers (=&) and the input to exclude memory (so
"ri", not "g").

Thanks to Etienne Lorrain and Chuck Ebbert for prompting this review.

f5c965abdf V4L/DVB (5821): Saa7134: add remote control support for LifeView FlyDVB-S LR300
It has been confirmed that the FlyDVB IR codes currently in the kernel
work with the LifeView FlyDVB-S LR300. This one line addition adds it
to the list of supported cards.

9b7cc42917 V4L/DVB (5820): Cleanup on cinergyT2: Remove unneeded if(1)
Before kernel 2.6.14, the driver checked for status before stopping the
thread. So, a compatibility test did exist. After 2.6.14, the
        if (state)
were replaced by:
        if (1)
However, it makes no sense to keep the if(1).

18f3fa1e2e V4L/DVB (5819): Cleanup: reorder some includes
Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files. This change 
also helps to make backports to properly work at the development tree.

7e520d09f1 V4L/DVB (5815): Cx88: i2c structure templates clean-up
Clean up the use of structure templates in cx88-i2c and cx88-vp3054-i2c.
For one thing, a real template is supposed to be read-only. And in some
cases it's more efficient to initialize the few fields we need
individually.

This clean-up shrinks cx88-i2c.o by 33% and cx88-vp3054-i2c.o by 49%
(x86_64).

8fb2191a74 V4L/DVB (5813): TUNER_TEA5761 kconfig fixes
The following doesn't make much sense:
drivers/media/video/Kconfig:
...
config TUNER_TEA5761
        tristate "TEA 5761 radio tuner (EXPERIMENTAL)"
...
drivers/media/video/Makefile:
...
ifneq ($(CONFIG_TUNER_TEA5761),)
  tuner-objs += tea5761.o
endif
...
With this setup, TUNER_TEA5761=m is equivalent to TUNER_TEA5761=y.
This patch therefore changes TUNER_TEA5761 to a bool.
The missing dependency on EXPERIMENTAL the prompt text indicates also
gets added by this patch.
Additionally, the Makefile entry can now be written in a more compact way.

ac7dc84584 V4L/DVB (5805): Bttv: Fix problems with probing for non-existent tuners
The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver.  Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.

For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module.  That can
be skipped for cards that don't need it.  The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.

The tuner into printk()s are also made nicer.  Levels are added, INFO or
WARNING, depending on the meaning.  For cards with no tuner, or no tuner
defined, a more informative message is printed.

Card has no tuner, before patch:
bttv0: tuner type=-1
 or
bttv0: tuner type=4

After patch:

bttv0: tuner absent

Card has a tuner, but the type isn't defined, before patch:
bttv0: tuner type=-1

After patch:
bttv0: tuner type unset   [<- also warning now, as the tuner won't work right]
