When the i2c-mv64xxx i2c driver is signalled to abort a transaction,
it aborts it immediately by issuing a stop condition on the bus.
This violates the i2c protocol and can cause what appears to be an i2c
bus hang. This patch delays issuing the stop condition until the i2c
device can reasonably expect a stop condition.
Also includes a minor fixup.

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:
int (*probe) (struct pcmcia_device *dev);
void (*remove) (struct pcmcia_device *dev);
int (*suspend) (struct pcmcia_device *dev);

I have recently been switching from using 2.4.32 on my trusty
old Sparc Blade 100 to using 2.6.15 . Some of the problems I ran into
were distorted video when the console was active (missing first
character, skipped dots) and when running X windows (colored snow,
stripes, missing pixels). A quick examination of the 2.6 versus 2.4
source for the ATY driver revealed alot of changes.
A closer look at the code/data for the 64GR/XL chip revealed
two minor "typos" that the rewriter(s) of the code made. The first is
a incorrect clock value (230 .vs. 235) and the second is a missing
flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have
fixed my problem. I tend to think the 235 value is the correct one,
as there is a 29.4 Mhz clock crystal close to the video chip and 235.2
(29.4*8) is too close to 235 to make it a coincidence.
The flag for M64F_SDRAM_MAGIC_PLL was dropped during the
changes made by adaplas in file revision 1.72 on the old bitkeeper
repository.
The change relating to the clock rate has been there forever,
at least in the 2.6 tree. I'm not sure where to look for the old 2.5
tree or if anyone cares when it happened.
On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the
clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also
requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL
properly for the DRAM.

IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ...
Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and
ide-tape, to autoload these modules depending on the probed media type of
the IDE device.
It is used by udev and replaces the former agent shell script of the hotplug
package, which was required to lookup the media type in the proc filesystem.
Using proc was racy, cause the media file is created after the hotplug event
is sent out.
The module autoloading does not take any effect, until something like the
following udev rule is configured:
SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}"
The module ide-scsi will not be autoloaded, cause it requires manual
configuration. It can't be, and never was supported for automatic setup in
the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported
media types, would just lead to a default blacklist entry anyway.

This patch (as604) makes the driver core hold a device's parent's lock
as well as the device's lock during calls to the probe and remove
methods in a driver. This facility is needed by USB device drivers,
owing to the peculiar way USB devices work:
A device provides multiple interfaces, and drivers are bound
to interfaces rather than to devices;
Nevertheless a reset, reset-configuration, suspend, or resume
affects the entire device and requires the caller to hold the
lock for the device, not just a lock for one of the interfaces.
Since a USB driver's probe method is always called with the interface
lock held, the locking order rules (always lock parent before child)
prevent these methods from acquiring the device lock. The solution
provided here is to call all probe and remove methods, for all devices
(not just USB), with the parent lock already acquired.
Although currently only the USB subsystem requires these changes, people
have mentioned in prior discussion that the overhead of acquiring an
extra semaphore in all the prove/remove sequences is not overly large.
Up to now, the USB core has been using its own set of private
semaphores. A followup patch will remove them, relying entirely on the
device semaphores provided by the driver core.
The code paths affected by this patch are:
device_add and device_del: The USB core already holds the parent
lock, so no actual change is needed.
driver_register and driver_unregister: The driver core will now
lock both the parent and the device before probing or removing.
driver_bind and driver_unbind (in sysfs): These routines will
now lock both the parent and the device before binding or
unbinding.
bus_rescan_devices: The helper routine will lock the parent
before probing a device.
I have not tested this patch for conflicts with other subsystems. As
far as I can see, the only possibility of conflict would lie in the
bus_rescan_devices pathway, and it seems pretty remote. Nevertheless,
it would be good for this to get a lot of testing in -mm.

The distinction between hotplug and uevent does not make sense these
days, netlink events are the default.
udev depends entirely on netlink uevents. Only during early boot and
in initramfs, /sbin/hotplug is needed. So merge the two functions and
provide only one interface without all the options.
The netlink layer got a nice generic interface with named slots
recently, which is probably a better facility to plug events for
subsystem specific events.
Also the new poll() interface to /proc/mounts is a nicer way to
notify about changes than sending events through the core.

David has a G5 with a printer. I am quite surprised that nobody else noticed
this before. Linus has a G5. Hackers hate printing in general, maybe.
We do not use BKL anymore, because one of code paths had a sleeping call,
so we had to use a semaphore. I am sure it's safe to use unlocked_ioctl.
The new ioctls return long and retval is int. It looks completely fine to me.

Noticed that my zd1201 adapter isn't "seen" by hal and NetworkManager.
The problem seems to be that unlike other network device drivers I
checked, zd1201 does not do a SET_NETDEV_DEV(), which makes it so a
"device" symlink is created under /sys/class/net/wlan0.
With the following patch the device symlink shows up, and now I am

This patch (as609) changes the way we keep track of power budgeting for
USB hubs and devices, and it updates the choose_configuration routine to
take this information into account. (This is something we should have
been doing all along.) A new field in struct usb_device holds the amount
of bus current available from the upstream port, and the usb_hub structure
keeps track of the current available for each downstream port.
Two new rules for configuration selection are added:
Don't select a self-powered configuration when only bus power
is available.
Don't select a configuration requiring more bus power than is
available.
However the first rule is #if-ed out, because I found that the internal
hub in my HP USB keyboard claims that its only configuration is
self-powered. The rule would prevent the configuration from being chosen,
leaving the hub & keyboard unconfigured. Since similar descriptor errors
may turn out to be fairly common, it seemed wise not to include a rule
that would break automatic configuration unnecessarily for such devices.
The second rule may also trigger unnecessarily, although this should be
less common. More likely it will annoy people by sometimes failing to
accept configurations that should never have been chosen in the first
place.
The patch also changes usbcore's reaction when no configuration is
suitable. Instead of raising an error and rejecting the device, now
the core will simply leave the device unconfigured. People can always
work around such problems by installing configurations manually through
sysfs.

hub driver's disconnect method runs. Hence it is safe to disconnect the
child device structures immediately instead of deferring the job.

This patch (as605) removes the private udev->serialize semaphore,

usb_trylock_device routine now uses the return convention of
down_trylock rather than down_read_trylock (they return opposite values
for no good reason).
A couple of other associated changes are included as well:
Now that we aren't concerned about HCDs that avoid using the
hcd glue layer, usb_disconnect no longer needs to acquire the
usb_bus_lock -- that can be done by usb_remove_hcd where it
belongs.
Devices aren't locked over the same scope of code in
usb_new_device and hub_port_connect_change as they used to be.

many VIA chips provide the PCI PM capabilities...) I think that doing

The device had 4 endpoints :
* 2 for data (use by usbatm). The incoming
endpoint could be iso or bulk. The modem seems buggy and produce lot's
of atm errors when using it in bulk mode for speed > 3Mbps, so iso
endpoint is need for speed > 3Mbps. At the moment iso endpoint need a
patched usbatm library and for this reason is not included in this patch.
* One bulk endpoint for uploading dsp firmware
* One irq endpoint that notices the driver
- if we need to upload a page of the dsp firmware
- an ack for read or write CMV and the value (for the read case).
If order to make the driver cleaner, we design synchronous
(read|write)_cmv :
-send a synchronous control message to the modem
-wait for an ack or a timeout
-return the value if needed.
In order to run these synchronous usb messages we need a kernel thread.
The driver has been tested with sagem fast 800 modems with different
eagle chipset revision and with ADI 930 since April 2005.

When the ehci-hcd driver prepares a control URB, it tests for a
zero-length data stage by looking at the transfer_dma value instead of
the transfer_buffer_length. (In fact it does this even for non-control
URBs, which is an additional aspect of the same bug.)
However, under certain circumstances it's possible for transfer_dma to
be 0 while transfer_buffer_length is non-zero. This can happen when a
freshly allocated page (mapped to address 0 and marked Copy-On-Write,
but never written to) is used as the source buffer for an OUT transfer.
This patch (as598) fixes the problem.

The attached patch makes a cleanup of isp116x-hcd. Most of the volume of
the patch comes from 2 sources: moving the code around to get rid of a
few function prototypes and reworking register dumping functions/macros.
Among other things, switched over from using procfs to debugfs.
Cleanup. The following changes were made:
- Rework register dumping code so it can be used for dumping
to both syslog and debugfs.
- Switch from procfs to debugfs..
- Die gracefully on Unrecoverable Error interrupt.
- Fix memory leak in isp116x_urb_enqueue(), if HC happens to
die in a narrow time window.
- Fix a 'sparce' warning (unnecessary cast).
- Report Devices Removable for root hub ports by default
(was Devices Permanently Attached).
- Move bus suspend/resume functions down in code to get rid of
a few function prototypes.
- A number of one-line cleanups.
- Add an entry to MAINTAINERS.

Until now the isp116x-hcd had no support to reinitialize the HC on
resume, if the controller lost its state during suspend. This patch,
generated against your Oct 26 git tree, adds that support. The patch is
basically the same as the one tested by Ivan Kalatchev, who reported the
problem, on 2.6.13.

To allow multiple platforms to use the PXA27x OHCI driver, the platform
code needs to be moved into the board specific files in
arch/arm/mach-pxa. This patch does this for mainstone and adds
preliminary hooks to allow other boards to use the driver.
This has been compile tested for mainstone and successfully run on Spitz
(Sharp Zaurus SL-C3000) with the addition of an appropriate board
support file.

Reading the MSR register on 8250-compatible UARTs results in any
modem status interrupts being cleared. To avoid missing any
status changes, arrange for get_mctrl() to read the current
status via check_modem_status(), which will process any pending
state changes for us.

readpage(), prepare_write(), and commit_write() callers are updated to
understand the special return code AOP_TRUNCATED_PAGE in the style of
writepage() and WRITEPAGE_ACTIVATE. AOP_TRUNCATED_PAGE tells the caller that
the callee has unlocked the page and that the operation should be tried again
with a new page. OCFS2 uses this to detect and work around a lock inversion in
its aop methods. There should be no change in behaviour for methods that don't
return AOP_TRUNCATED_PAGE.
WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are
made enums so that kerneldoc can be used to document their semantics.

Some G5s still occasionally experience shutdowns due to overtemp
conditions despite the recent fix. After analyzing logs from such
machines, it appears that the overtemp code is a bit too quick at
shutting the machine down when reaching the critical temperature (tmax +
8) and doesn't leave the fan enough time to actually cool it down. This
happens if the temperature of a CPU suddenly rises too high in a very
short period of time, or occasionally on boot (that is the CPUs are
already overtemp by the time the driver loads).
This patches makes the code a bit more relaxed, leaving a few seconds to
the fans to do their job before kicking the machine shutown.
