The appletouch geyser3 devices found in the Intel Macs (and possibly
some later PPC ones?) send a constant stream of packets after the first
touch. This results in the kernel waking up around once every couple of
milliseconds to process them, making it almost impossible to spend any
significant amount of time in C3 state on a dynamic HZ kernel. Sending
the mode initialization code makes the device shut up until it's touched
again. This patch does so after receiving 10 packets with no interesting

2804 usb_set_serial_port_data(serial->port[i], NULL);
2805 }
...
It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.
This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

This patch (as937) fixes a minor bug in the autosuspend usage-counting
code. Each hub's usage counter keeps track of the number of
unsuspended children. However the current driver increments the
counter after registering a new child, by which time the child may
already have been suspended and caused the counter to go negative.
The obvious solution is to increment the counter before registering
the child.

This patch (as934) adds a new readonly binary sysfs attribute file
called "descriptors" for each USB device. The attribute contains the
device descriptor followed by the raw descriptor entry (config plug
subsidiary descriptors) for the current configuration.
Having this information available in fixed-format binary makes life a
lot easier for user programs by avoiding the need to open, read, and
parse multiple sysfs text files.
The information in this attribute file is much like that in usbfs's
device file, but there are some significant differences:
The 2-byte fields in the device descriptor are left in
little-endian byte order, as they appear on the bus and
in the kernel.
Only one raw descriptor set is presented, that of the
current configuration.
Opening this file will not cause a suspended device to be
autoresumed.
The last item in particular should be a big selling point for libusb,
which currently forces all USB devices to be resumed as it scans the
device tree.

This patch (as931b), adapted from a patch by Olav Kongas, makes a small
set of conservative changes to the isp116x-hcd driver in preparation
for the removal of urb->status.
finish_request() is moved up in the source and is called
as soon as the URB is known to have completed, rather than
after all the active endpoints have been scanned.
The status of a completed URB is kept in a local variable
and copied to urb->status only when the URB is about to be
given back.
-EREMOTEIO error status for control transfers is set after
the status stage rather than when the short packet arrives.

I found the first regresson in the rewritten ("all dynamic" and "no races")
driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB
being submitted successfuly. This causes the application to resubmit the

merely queued. It is the same behaviour as with the old version.

While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from

The driver used to depend on BIOS settings for deciding whether it is OK
to use DMA. However it seems that BIOS doesn't always handle all cases

* Always set ->autotune so PIO gets correctly auto-tuned (previously
->autotune was only set when ->dma_base wasn't available, however
->ide_dma_check()/->speedproc() was always trying to tune PIO when
tuning DMA).
* Move code responsible for programming chipset for PIO mode from
svwks_tune_chipset() to svwks_tune_pio(). Don't tune PIO when tuning
DMA (this is no longer needed since ->autotune is always set now).
* Handle PIO modes early in svwks_tune_chipset() so DMA configuration
registers don't get cleared when programming PIO mode.
* Bump driver version.

* Add sil_tuneproc() wrapper for siimage_tuneproc() which also sets
PIO mode on the device.
* Add missing ide_get_best_pio_mode() call to sil_tuneproc() so
"pio" == 255 (autotune) is handled correctly (previously PIO0 was used)
and "pio" values > 4 && < 255 are filtered to PIO4 (instead of PIO0).
* Add code limiting maximum PIO mode according to the pair device capabilities
to sil_tuneproc().
* Convert users of config_siimage_chipset_for_pio() to use sil_tune_pio() and
sil_tuneproc(). This fixes PIO fallback in siimage_config_drive_for_dma() to
use max PIO mode available instead of PIO4 (config_siimage_chipset_for_pio()
used wrong arguments for ide_get_best_pio_mode() and as a results always
tried to set PIO4).
* Remove no longer needed siimage_taskfile_timing()
and config_siimage_chipset_for_pio().
* Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
from siimage_speedproc()
* Bump driver version.
v2:

- correct pair device check
- trim only taskfile PIO to the slowest of the master/slave
- enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes

Various old IDE drivers go mapping ROM devices for no apparent reason and
without using the ROM mapping API we now have. They don't actually use
the ROM they map and the new libata drivers are happy without it being
mapped so rather than port them lets just junk it for the next -rc1.

Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
the cmpxchg64b feature and enables compilation of the set_64bit() family.
Since the option is dependent on PAE, and since KVM depends on set_64bit(),
this effectively disables KVM on i386 nopae.
Simplify by removing the config option altogether: the boot check is made
dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
without constraints. It is up to users to check for the feature flag (KVM
does not as virtualiation extensions imply its existence).

* I have experimental evidence that the W83627EHG needs more than 1
second to refresh all the measured values. Increase the caching time to
1.5 second.
* When changing a fan clock divider, the corresponding fan speed
measurement register is no longer valid, until the next time the chip
will refresh it. One way to fix this is to pretend that the cache is
still valid for one more period (1.5 second.)

If the Super-I/O device is disabled, it is likely the BIOS has a good
reason for leaving it disabled, so give a warning when enabling it --
it's not likely to be wired correctly or be able to give good data.
Also, if the Super-I/O device is configured with an address of 0, the
driver refuses to initialize it.

Fix a potential race condition when some hardware monitoring platform
drivers are being unloaded. I believe that the driver data pointer
shouldn't be cleared before all the sysfs files are removed, otherwise
a sysfs callback might attempt to dereference a NULL pointer. I'm not
sure exactly what the driver core protects drivers against, so let's
play it safe.
While we're here, clear the driver data pointer when probe fails, so
as to not leave an invalid pointer behind us.

We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:
in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault
Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.
We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.

ide-disk calls
ide_end_request(drive, 0, 0);
to finish an unknown request, but this doesn't work so well for non-fs
requests, since ide_end_request() internally looks at ->hard_cur_sectors
to see how much data to end. Only file system requests store a transfer
value in there, pc requests fill out ->data_len as a byte based transfer
value instead.
Since we ask to end 0 bytes of that request, it will never be terminated
and ide-disk gets stuck in a loop "handling" that same request over and
over.
Switch __ide_end_request() to take a byte based transfer count, and
adjust ide_end_request() to look at the right field to determine how
much IO to end when it's being passed in 0.

Some simple fixes to properly reference counter values from the block
attribute level of edac_device objects. Properly sequencing the array pointer
was added, resulting in correct identification of block level attributes from
their base class functions.
Added more verbose debug statement for event tracking.
Also during some corner testing, found a bug in the store/show sequence
of operations for the block attribute/controls management.
An old intermediate structure for 'blocks' was still in the processing
pipeline. This patch removes that old structure and correctly utilizes the
new struct edac_dev_sysfs_block_attribute for passing control from the sysfs
to the low level store/show function of the edac driver.
Now the proper kobj pointer to passed downward to the store/show
functions.

This patch refactors the 'releasing' of kobjects for the edac_mc type of
device. The correct pattern of kobject release is followed.
As internal kobjs are allocated they bump a ref count on the top level kobj.
It in turn has a module ref count on the edac_core module. When internal
kobjects are released, they dec the ref count on the top level kobj. When the
top level kobj reaches zero, it decrements the ref count on the edac_core
object, allow it to be unloaded, as all resources have all now been released.
