Wim Van Sebroeck deb9197b70 watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver
Jiri Slaby: 28d41f53f broke temperature sensors on a ICH10 chipset

The iTCO_wdt driver disables the SMI. This breaks good working of newer hardware.
The disabling of the SMI by the TCO logic dates back from the i810-tco driver
from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes
install handlers reset or disable the watchdog timer instead of resetting the system.
The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the
SMI_EN register) to prevent this from happening.

This however has strange effects on newer hardware. So we are in a situation that
a fix for broken old hardware affects newer hardware.

The correct solution is to make this fix an option (with the new module parameter:
turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version.

the next patch will be to move this in the start and stop functions of the driver
and to add a new module parameter for the global_smi_en bit and to get rid of the
vendor_support code.

This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that
have a broken BIOS implementation concerning TCO logic. In these case the module
parameter turn_SMI_watchdog_clear_off=1 will need to be added.

Venkat Subbiah 47bfd05813 watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREAD
This is to exclude it from force threading to allow RT patch set to work.

The watchdog timers are per-CPU and the addresses of register that reset
the timer are calculated based on the current CPU.  Therefore we cannot
allow it to run on a thread on a different CPU.  Also we only do a
single register write, which is much faster than scheduling a handler
thread.

And while on this line remove IRQF_DISABLED as this flag is a NOP.

Alan Stern b2c0a863e1 USB: Update last_busy time after autosuspend fails
Originally, the runtime PM core would send an idle notification
whenever a suspend attempt failed.  The idle callback routine could
then schedule a delayed suspend for some time later.

However this behavior was changed by commit
f71648d73c (PM / Runtime: Remove idle
notification after failing suspend).  No notifications were sent, and
there was no clear mechanism to retry failed suspends.

This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down.  A companion
patch changes the PM core's behavior, but we also need to change the
USB core.  In particular, this patch (as1493) updates the device's
last_busy time when an autosuspend fails, so that the PM core will
retry the autosuspend in the future when the delay time expires
again.

The RC error state flush logic in qib_make_rc_req() could return all
of the acked wqes and potentially have emptied the queue.  It would
then unconditionally try return a flush completion via
qib_send_complete() for an invalid wqe, or worse a valid one that is
not queued. The panic results when the completion code tries to
maintain an MR reference count for a NULL MR.

This fix modifies logic to only send one completion per
qib_make_rc_req() call and changing the completion status from
IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress.

The outer loop will call as many times as necessary to flush the queue.

We also went further and did DMA mapping only once, with

using different buffers, one for requests and one for responses, and

Jean Delvare eff7687d47 hwmon: (w83627ehf) Add support for the W83627UHG
This is essentially a stripped down version of the W83627DHG. Noticeable
difference is that it is still powered with +5V, as older models, even
though the ADC resolution is 8 mV as newer models have.

Thanks to Ulf Bruman (Saab Group) for doing all the testing.

Jean Delvare 6ba71de5f8 hwmon: (w83627ehf) Clean up probe function
The probe function has grown pretty large, I think it's time for some
cleanups, starting with these two simple ones:
* Move temp3/in6 check for the W83667HG later in the function, where
  it is done for all other chip types.
* Move temperature register setting to a separate function, to avoid
  code duplication.

Jean Delvare 2265cef275 hwmon: (w83627ehf) Properly report PECI and AMD-SI sensor types
When temperature sources are PECI or AMD-SI agents, it makes no sense
to report their type as diode or thermistor. Instead we must report
their digital nature.

Jean Delvare b2589ab02b hwmon: (lm90) Make code more readable
Clean up the code to make it more readable:
* Remove reg_ and new_ prefixes from variable names, they made the
  names longer, causing extra line breaks, while not adding much
  value.
* Introduce struct device dev* = &client->dev in two functions, to
  avoid repeating client->dev everywhere in these functions.

Jean Delvare 8dc089d68b hwmon: (lm90) Fix warnings
With some configuration option combinations, we get the following
warnings:

drivers/hwmon/lm90.c: In function 'lm90_detect':
drivers/hwmon/lm90.c:1114: warning: 'chip_id' may be used uninitialized
in this function
drivers/hwmon/lm90.c:1114: warning: 'reg_config1' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1114: warning: 'reg_convrate' may be used

uninitialized in this function
drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used
uninitialized in this function

We can solve these easily by reading the register values first and
checking for errors later. These errors should be very rare, even in
the case of failed detection, so this change has no impact on
performance. And this makes checkpatch.pl happier.

I am under the impression that error paths in functions

RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems

the Kconfig symbol and the macro.)

Note there's also a module parameter 'use_xtal' to influence all this.
