Jean Delvare dfdee5f00c i2c: Delete unused adapter IDs
Delete unused I2C adapter IDs. Special cases are:

* I2C_HW_B_RIVA was still set in driver rivafb, however no other
  driver is ever looking for this value, so we can safely remove it.
* I2C_HW_B_HDPVR is used in staging driver lirc_zilog, however no
  adapter ID is ever set to this value, so the code in question never
  runs. As the code additionally expects that I2C_HW_B_HDPVR may not
  be defined, we can delete it now and let the lirc_zilog driver
  maintainer rewrite this piece of code.

Big thanks for Hans Verkuil for doing all the hard work :)

Jim Bos 22d3243de8 Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)
The fix in commit 6b4e81db25 ("i8k: Tell gcc that *regs gets
clobbered") to work around the gcc miscompiling i8k.c to add "+m
(*regs)" caused register pressure problems and a build failure.

Changing the 'asm' statement to 'asm volatile' instead should prevent
that and works around the gcc bug as well, so we can remove the "+m".

[ Background on the gcc bug: a memory clobber fails to mark the function
  the asm resides in as non-pure (aka "__attribute__((const))"), so if
  the function does nothing else that triggers the non-pure logic, gcc
  will think that that function has no side effects at all. As a result,
  callers will be mis-compiled.

  Adding the "+m" made gcc see that it's not a pure function, and so
  does "asm volatile". The problem was never really the need to mark
  "*regs" as changed, since the memory clobber did that part - the
  problem was just a bug in the gcc "pure" function analysis  - Linus ]

Jean Delvare 52d159eecc hwmon: (w83795) Check for BEEP pin availability
On the W83795ADG, there's a single pin for BEEP and OVT#, so you
can't have both. Check the configuration and don't create beep
attributes when BEEP pin is not available.

The W83795G has a dedicated BEEP pin so the functionality is always
available there.

Jean Delvare 793c51d5fd hwmon: (w83795) Clear intrusion alarm immediately
When asked to clear the intrusion alarm, do so immediately. We have to
invalidate the cache to make sure the new status will be read. But we
also have to read from the status register once to clear the pending
alarm, as writing to CLR_CHS surprising won't clear it automatically.

Jean Delvare cf6b9ea661 hwmon: (w83795) Read the intrusion state properly
We can't read the intrusion state from the real-time alarm registers
as we do for all other alarm flags, because real-time alarm bits don't
stick (by definition) and the intrusion state has to stick until
explicitly cleared (otherwise it has little value.)

So we have to use the interrupt status register instead, which is read
from the same address but with a configuration bit flipped in another
register.

Jean Delvare d5ab845a13 hwmon: (w83795) Expose fan control method
Expose fan control method (DC vs. PWM) using the standard sysfs
attributes. I've made it read-only as the board should be wired for
a given mode, the BIOS should have set up the chip for this mode, and
you shouldn't have to change it. But it would be easy enough to make
it changeable if someone comes up with a use case.

Jean Delvare 61ec2da506 hwmon: (lm95241) Check validity of input values
This clears the following build-time warnings I was seeing:

drivers/hwmon/lm95241.c: In function "set_interval":

drivers/hwmon/lm95241.c:219:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result

This also fixes a small race in set_interval() as a side effect: by
working with a temporary local variable we prevent data->interval from
being accessed at a time it contains the interval value in the wrong
unit.

Jim Bos 6b4e81db25 i8k: Tell gcc that *regs gets clobbered
More recent GCC caused the i8k driver to stop working, on Slackware
compiler was upgraded from gcc-4.4.4 to gcc-4.5.1 after which it didn't
work anymore, meaning the driver didn't load or gave total nonsensical
output.

As it turned out the asm(..) statement forgot to mention it modifies the
*regs variable.

Tejun Heo 2a5f07b5ec libata: fix NULL sdev dereference race in atapi_qc_complete()
SCSI commands may be issued between __scsi_add_device() and dev->sdev
assignment, so it's unsafe for ata_qc_complete() to dereference
dev->sdev->locked without checking whether it's NULL or not.  Fix it.

Rafael J. Wysocki 6c4f199411 gianfar: Do not call device_set_wakeup_enable() under a spinlock
The gianfar driver calls device_set_wakeup_enable() under a spinlock,
which causes a problem to happen after the recent core power
management changes, because this function can sleep now.  Fix this
by moving the device_set_wakeup_enable() call out of the
spinlock-protected area.

Hao Zheng 5e09a10521 ixgbe: Look inside vlan when determining offload protocol.
Currently the skb->protocol field is used to setup various
offloading parameters on transmit for the correct protocol.
However, if vlan offloading is disabled or otherwise not used,
the protocol field will be ETH_P_8021Q, not the actual protocol.
This will cause the offloading to be not performed correctly,
even though the hardware is capable of looking inside vlan tags.
Instead, look inside the header if necessary to determine the
correct protocol type.

To some extent this fixes a regression from 2.6.36 because it
was previously not possible to disable vlan offloading and this
error case was not exposed.

Jason Wang 167c25e4c5 virtio-net: init link state correctly
For device that supports VIRTIO_NET_F_STATUS, there's no need to
assume the link is up and we need to call nerif_carrier_off() before
querying device status, otherwise we may get wrong operstate after
diver was loaded because the link watch event was not fired as
expected.

For device that does not support VIRITO_NET_F_STATUS, we could not get
its status through virtnet_update_status() and what we can only do is
always assuming the link is up.

The reason appears to be ucc_geth_stop meets adjust_link as the
PHY reports PHY changes. I belive adjust_link hangs somewhere,
holding the PHY lock, because ucc_geth_stop disabled the
controller HW.
Fix is to stop the PHY before disabling the controller.
