Add bus_type probe, remove and shutdown methods to replace the
corresponding methods in struct device_driver. This matches
the way we handle the suspend/resume methods.
Since the bus methods override the device_driver methods, warn
if a device driver is registered whose methods will not be
called.
The long-term idea is to remove the device_driver methods entirely.

- Tunertype struct redefined to allow one or more tuner_params structs
per tuner definition, one for each video standard.
- Each tuner_params struct has an element containing an arbitrary
amount of tuner_ranges.
(this is needed for dvb tuners - to be handled later)
- A tuner_range may be referenced by multiple tuner_params structs.
There are many duplicates in here. Reusing tuner_range structs,
rather than defining new ones for each tuner, will cut down on
memory usage, and is preferred when possible.
- tunertype struct contains an element, has_tda988x.
We must set this for all tunertypes that contain a tda988x
chip, and then we can remove this setting from the various
card structs.
- Improves tuners array memory usage efficiency.
- Right now, all tuners are using the first tuner_params[] array element
for analog mode. In the future, we will be merging similar tuner
definitions together, such that each tuner definition will have a
tuner_params struct for each available video standard. At that point,
the tuner_params[] array element will be chosen based on the video
standard in use.

Our systems have been crashing during testing of PCI HotPlug
support in the various networking components. We've faulted in
the bonding driver due to a bug in bond_alb.c:tlb_clear_slave()
In that routine, the last modification to the TLB hash table is

This patch allows the Atmel driver to work correctly with wpa_supplicant

should not affect current behavior of the driver. The patch does four
things:
1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and
SIOCGIWAUTH calls for unencrypted and WEP operation
2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and
should turn off any previous forced WAP address
3) Sends association and de-association events to userspace at most of
the appropriate times
4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location
which are actually unused anyway

We have identified two related bugs in the e100 driver.
Both bugs are related to manipulation of the MDI control register.
The first problem is that the Ready bit is being ignored when writing to
the Control register; we noticed this because the Linux bonding driver
would occasionally come to the spurious conclusion that the link was down
when querying Link State. It turned out that by failing to wait for a
previous command to complete it was selecting what was essentially a random
register in the MDI register set. When we added code that waits for the
Ready bit (as shown in the patch file below) all such problems ceased.
The second problem is that, although access to the MDI registers involves
multiple steps which must not be intermixed, nothing was defending against
two or more threads attempting simultaneous access. The most obvious
situation where such interference could occur involves the watchdog versus
ioctl paths, but there are probably others, so we recommend the locking
shown in our patch file.

While trying to get SUSE's SLES9 working on system with more than 4GB we've
noticed that SCSI layer happilly passes addresses over 4GB to the buslogic
driver, which is quite a big problem as buslogic can generate only 32bit
busmastering cycles.
Fortunately in the current kernels this problem does not exist anymore as
SCSI layer now assumes 4GB capable device by default, but it is still good
idea to pass correct device structure to the SCSI layer. If nothing else,
/sys/block/sda/device now points to
/sys/devices/pci0000:00/0000:00:10.0/host0/... instead of
/sys/devices/platform/host0/... like it did in the past.
Change does nothing for ISA based BusLogic adapters, they'll still end
under platform (and they are probably broken for long time as I do not see
anything forcing ISA 16MB limit for them).

The API and code have been through various bits of initial review by
serial driver people but they definitely need to live somewhere for a
while so the unconverted drivers can get knocked into shape, existing
drivers that have been updated can be better tuned and bugs whacked out.
This replaces the tty flip buffers with kmalloc objects in rings. In the
normal situation for an IRQ driven serial port at typical speeds the
behaviour is pretty much the same, two buffers end up allocated and the
kernel cycles between them as before.
When there are delays or at high speed we now behave far better as the
buffer pool can grow a bit rather than lose characters. This also means
that we can operate at higher speeds reliably.
For drivers that receive characters in blocks (DMA based, USB and
especially virtualisation) the layer allows a lot of driver specific
code that works around the tty layer with private secondary queues to be
removed. The IBM folks need this sort of layer, the smart serial port
people do, the virtualisers do (because a virtualised tty typically
operates at infinite speed rather than emulating 9600 baud).
Finally many drivers had invalid and unsafe attempts to avoid buffer
overflows by directly invoking tty methods extracted out of the innards
of work queue structs. These are no longer needed and all go away. That
fixes various random hangs with serial ports on overflow.
The other change in here is to optimise the receive_room path that is
used by some callers. It turns out that only one ldisc uses receive room
except asa constant and it updates it far far less than the value is
read. We thus make it a variable not a function call.
I expect the code to contain bugs due to the size alone but I'll be
watching and squashing them and feeding out new patches as it goes.
Because the buffers now dynamically expand you should only run out of
buffering when the kernel runs out of memory for real. That means a lot of
the horrible hacks high performance drivers used to do just aren't needed any
more.
Description:
tty_insert_flip_char is an old API and continues to work as before, as does
tty_flip_buffer_push() [this is why many drivers dont need modification]. It
does now also return the number of chars inserted
There are also
tty_buffer_request_room(tty, len)
which asks for a buffer block of the length requested and returns the space
found. This improves efficiency with hardware that knows how much to
transfer.
and tty_insert_flip_string_flags(tty, str, flags, len)
to insert a string of characters and flags
For a smart interface the usual code is
len = tty_request_buffer_room(tty, amount_hardware_says);
tty_insert_flip_string(tty, buffer_from_card, len);
More description!
At the moment tty buffers are attached directly to the tty. This is causing a
lot of the problems related to tty layer locking, also problems at high speed
and also with bursty data (such as occurs in virtualised environments)
I'm working on ripping out the flip buffers and replacing them with a pool of
dynamically allocated buffers. This allows both for old style "byte I/O"
devices and also helps virtualisation and smart devices where large blocks of
data suddenely materialise and need storing.
So far so good. Lots of drivers reference tty->flip.*. Several of them also
call directly and unsafely into function pointers it provides. This will all
break. Most drivers can use tty_insert_flip_char which can be kept as an API
but others need more.
At the moment I've added the following interfaces, if people think more will
be needed now is a good time to say
int tty_buffer_request_room(tty, size)
Try and ensure at least size bytes are available, returns actual room (may be
zero). At the moment it just uses the flipbuf space but that will change.
Repeated calls without characters being added are not cumulative. (ie if you
call it with 1, 1, 1, and then 4 you'll have four characters of space. The
other functions will also try and grow buffers in future but this will be a
more efficient way when you know block sizes.
int tty_insert_flip_char(tty, ch, flag)
As before insert a character if there is room. Now returns 1 for success, 0
for failure.
int tty_insert_flip_string(tty, str, len)
Insert a block of non error characters. Returns the number inserted.
int tty_prepare_flip_string(tty, strptr, len)
Adjust the buffer to allow len characters to be added. Returns a buffer
pointer in strptr and the length available. This allows for hardware that
needs to use functions like insl or mencpy_fromio.

Current console blanking code is broken. It will first do a normal blank,
then start the VESA blank timer if vesa_off_interval != 0, and then proceed
to do the VESA blanking directly. After the timer expires it will do the
VESA blanking a second time. Also the vesa_powerdown() function doesn't
allow all VESA modes to be used.
With this patch the behaviour is:
1. Blank: vesa_off_interval != 0 -> Do normal blank
vesa_off_interval == 0 -> Do VESA blank
2. Start the VESA blank timer if vesa_off_interval != 0 and
vesa_power_mode != 0.
It also gets rid of the limiting vesa_powerdown() function.

The I2C bus of the S3 Savage2000 is supposed to work the same way the Savage4
does. At least, the legacy i2c-savage4 driver handled both devices the same
way.

From: Bugzilla Bug 5351
"After resuming from S3 (suspended while in X), the LCD panel stays black .
However, the laptop is up again, and I can SSH into it from another
machine.
I can get the panel working again, when I first direct video output to the
CRT output of the laptop, and then back to LCD (done by repeatedly hitting
Fn+F5 buttons on the Toshiba, which directs output to either LCD, CRT or
TV) None of this ever happened with older kernels."
This bug is due to the recently added vesafb_blank() method in vesafb. It
works with CRT displays, but has a high incidence of problems in laptop
users. Since CRT users don't really get that much benefit from hardware
blanking, drop support for this.

- Kexec on panic functionality allocates memory for saving cpu registers in
case of system crash event. Address of this allocated memory needs to be
exported to user space, which is used by kexec-tools.
- Previously, a single /sys/kernel/crash_notes entry was being exported as
memory allocated was a single continuous array. Now memory allocation being
dyanmic and per cpu based, address of per cpu buffer is exported through
"/sys/devices/system/cpu/cpuX/crash_notes"
