"[PATCH] optimize follow_hugetlb_page" breaks mlock on hugepage areas.
I mis-interpret pages argument and made get_page() unconditional. It
should only get a ref count when "pages" argument is non-null.

find_trylock_page() is an odd interface in that it doesn't take a reference
like the others. Now that XFS no longer uses it, and its last remaining
caller actually wants an elevated refcount, opencode that callsite and
schedule find_trylock_page() for removal.

Redboot simply sets the first character of a fis entry to 0xff on "fis

without this patch any entries after a deleted image would not be detected.

Current cmdlinepart.c uses offset value 0 to specify a continuous
partition. This prevents creating a second partition starting at 0.
For example, I can split 4MB device using "mtdparts=id:2M,2M", but I can
not do "mtdparts=id:2M@2M,2M@0" to swap mtd0 and mtd1.
This patch introduces special OFFSET_CONTINUOUS value for a continuous
partition and allows 0 for offset value.
Also this patch replaces 0xffffffff with UINT_MAX for SIZE_REMAINING.

This patch adds a mixer control which allows the user to switch the Aux
playback between the internal Aux jack, Wavetable, and Rear Line-In on
Aureon Universe cards.
For switching, a PCA9554 (8-line GPIO with I2C interface) and a 74HC4052
(dual 4-way mux/demux) are used. Output 0 and 1 of the PCA9554 are
connected to the select pins of the 74HC4052. The I2C interface of the
PCA9554 is connected to the card's internal SPI bus which is also used
to control the WM8770 and CS8415. SPI and I2C on the same lines...
To communicate with the PCA9554 the WM8770 and CS8415 are disabled and
an I2C Stop Condition is generated before the Start Condition (needed
for synchronisation because other SPI traffic appear to confuse the
PCA9554). Then a normal I2C data transfer takes place. Programming must
be done ridiculously slow; in theory, 4.7us is the minimum delay time
for normal-speed I2C according to the datasheet, but even with 10us
switching was unreliable. The Windows driver from Terratec does the
programming very slowly, too (checked with an oscilloscope).

On a new board revision for pcxhr boards, the
PCXHR_CHIPSC_GPI_USERI bit is no more supported.
The cards concerned have a REV01 in their PCI ID.
As the current driver tests this bit and does not load the
first Xilinx binary when it's 1, the card will crash on Xilinx
access over PCI. (the PCI will freeze ....)
The fix (fix to version 1.0.11rc4) works for both REV00 and
REV01 cards.

The following patch relative to CVS from 20060324 adds the following
features to the Realtek HDA codec.
1) Define two new pin modes: ALC_PIN_DIR_IN_NOMICBIAS and
ALC_PIN_DIR_INOUT_NOMICBIAS. These can be used with jack mode switch
definitions in mixers to prevent the user being offered the mic bias
options if the hardware doesn't support it.
2) Add the ability to have different input mux definitions for different
ADCs. This is needed because the ALC260 chip uses different mux layouts
for the two onboard ADCs. A new field (num_mux_defs) was added to the
alc_spec and alc_config_preset structures to support this.
3) Adjust numerous comments to make them consistent with the above changes.
4) Utilise the new multi-mux definition functionality for the ALC260 fujitsu
model to allow recording of the mixer output.
5) Utilise the new multi-mux definition functionality for the ALC260 test
model to make the mux selections a little less confusing.
6) Allow the headphone jack of the ALC260 acer model to be retasked in
the mixer.
6) Utilise the new multi-mux definition functionality for the ALC260 acer
model to give access to the mixer output and the retasked headphone
jack.
At this stage the *_NOMICBIAS modes are not used. We have reports that the
"Line" jack of at least some Acer models doesn't pass the bias out, and we
also know that NIDs 0x0f and 0x10 don't seem to accept the mic bias requests
at all. However, I feel we need to collect more evidence on both counts
before committing to the use of *_NOMICBIAS. In the case of the Acers, it's
not clear whether this issue (probably caused by the inclusion of DC
blocking capacitors) affects all Acer models or just a small number. With
the issue with NIDs 0x0f and 0x10 it's unclear whether this is a hardware
bug which will be addressed in later chip revisions or if it's an
intentional restriction. The datasheet makes no mention of the restriction
so at this stage I'm inclined to consider it a hardware bug. Comments in
the source reflect this reasoning.
On a similar theme, the headphone jack of the Fujitsu S7020 also doesn't
appear to pass mic bias voltage. I'm still investigating this however.
With the ability to retask the headphone jack, owners of ALC260-based Acer
laptops should now be able to record 4 channels of audio if they desire. The
multiple mux definitions allow this jack to be presented from both ADCs
(since this mux input is one of those which differs between the muxes).
This patch has been tested on a Fujitsu S7020 laptop and appears to behave
itself both for the "test" and "fujitsu" models. Definitions using only a
single mux specification also work. Other ALC chips should be fine but I
cannot test these myself. The "auto" modes should also continue to function
but again I have not verified this.

Attached you'll find an ALSA driver for AdLib FM cards. An AdLib card is
just an OPL2, which was already supported by sound/drivers/opl3, so only
very minimal bus-glue is needed. The patch applies cleanly to both
2.6.16 and 2.6.16-mm1.
The driver has been tested with an actual ancient 8-bit ISA AdLib card
and works fine. It also works fine for an OPL3 {,emulation} as still
found on many ISA soundcards but given that AdLib cards don't have their
own mixer, upping the volume from 0 might be a problem without the card
driver already loaded and driving the OPL3.

This ugly hack add support for Siemens MC45 PCMCIA GPRS card (which is
identical to Possio GCC, and which is offered by one of our local GPRS
providers). Card has unfortunate feature that after poweron oxcf950 chip
is fully powered and works, but attached MC45 modem is powered down :-(
There is a special sequence (which takes 1 sec :-( ) to poweron MC45 (and
after MC45 powers on, it takes more than 2 secs until firmware fully
boots...) which needs to be executed after all powerons.
I'm really not familiar with PCMCIA subsystem, so I have no idea whether I
should issue request_region() on rest of oxcf950 address range (0-7 is
UART, 8-F are special configuration registers), or how this should be
better integrated with PM system and so on - I just put it in same place
where another hack already lived...
Card uses 18.432MHz XTAL, so to get it to work you must add lines below to
the /etc/pcmcia/serial.opts.
