Jean Delvare 8acf07c5a7 hwmon: (it87) Properly handle wrong sensor type requests
Currently, if someone tries to set the thermal sensor type to an
unsupported value, subsequent accesses to the chip may temporarily
show the sensor in question as disabled. Use a temporary variable
and only update the cached value on success, to prevent such
confusion.

Jean Delvare a00afb97e2 hwmon: (it87) Don't arbitrarily enable temperature channels
Temperature channels can be used in 2 different modes (thermistor and
thermal diode) and we don't know which one, if any, is correct for
every given board. So don't arbitrarily choose one. Instead, leave the
temperature channels untouched. They can be configured from user-space
if needed anyway.

Jerome Oufella 328a2c22ab hwmon: (sht15) Fix sht15_calc_temp interpolation function
I discovered two issues.
First the previous sht15_calc_temp() loop did not iterate through the
temppoints array since the (data->supply_uV > temppoints[i - 1].vdd)
test is always true in this direction.

Also the two-points linear interpolation function was returning biased
values due to a stray division by 1000 which shouldn't be there.

[JD: Also change the default value for d1 from 0 to something saner.]

Rusty Russell 091ebf07a2 lguest: stop using KVM hypercall mechanism
This is a partial revert of 4cd8b5e2a1 "lguest: use KVM hypercalls";
we revert to using (just as questionable but more reliable) int $15 for
hypercalls.  I didn't revert the register mapping, so we still use the
same calling convention as kvm.

KVM in more recent incarnations stopped injecting a fault when a guest
tried to use the VMCALL instruction from ring 1, so lguest under kvm
fails to make hypercalls.  It was nice to share code with our KVM
cousins, but this was overreach.

Rusty Russell 5094aeafbb lguest: workaround cmpxchg8b_emu by ignoring cli in the guest.
It's only used by cmpxchg8b_emu (see db677ffa5f for the gory
details), and fixing that to be paravirt aware would be more work than
simply ignoring it (and AFAICT only help lguest).  This makes lguest
work on machines which have cmpxchg8b, for kernels compiled for older
processors.

(We can't emulate it properly: the popf which expects to restore interrupts
does not trap).

Michael S. Tsirkin 0110d6f22f tun: orphan an skb on tx
The following situation was observed in the field:
tap1 sends packets, tap2 does not consume them, as a result
tap1 can not be closed. This happens because
tun/tap devices can hang on to skbs undefinitely.

As noted by Herbert, possible solutions include a timeout followed by a
copy/change of ownership of the skb, or always copying/changing
ownership if we're going into a hostile device.

This patch implements the second approach.

Note: one issue still remaining is that since skbs
keep reference to tun socket and tun socket has a
reference to tun device, we won't flush backlog,
instead simply waiting for all skbs to get transmitted.
At least this is not user-triggerable, and
this was not reported in practice, my assumption is
other devices besides tap complete an skb
within finite time after it has been queued.

A possible solution for the second issue
would not to have socket reference the device,
instead, implement dev->destructor for tun, and
wait for all skbs to complete there, but this
needs some thought, probably too risky for 2.6.34.

Andreas Ferber 847253b948 MIPS: Fix SSB PCIcore IO resource management
The SSB PCIcore code reused the IO resource fixup code from the original
2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack
for doing PCI IO resource configuration back then (the boot loader
doesn't configure PCI devices on this platform).

However, this code is no longer necessary since the kernel now can do
PCI resource management fine all by itself, so remove the old code.

When removing the code, it becomes obvious that the mem_offset setting
in the PCIcore driver was wrong, however this was masked by the fixup
code before, except in a few cases involving yenta_socket. For BCM47xx,
the correct offset is 0, and since this is the only device using PCIcore
in host mode, the offset can simply be removed unconditionally.

Anil Veerabhadrappa 490475a993 [SCSI] bnx2i: Bug fixes related to MTU change issue when there are active iscsi sessions
bnx2i driver has to wait and cleanup all iscsi endpoints before
returning from bnx2i_stop(). This is to make sure all chip resources
are freed before chip is reset.

As the requirements for 1G and 10G chipsets is different, added
per-device 'hba_shutdown_tmo' parameter to adapter structure

If the connections are not torn down by the daemon within this timeout
period, 'cid's will be leaked in 10G device. 1G devices are more
flexible and do not leak any resources because the whole chip ports
gets reset when MTU is changed or ethtool selftest is run

fixed a minor issue in bnx2i_ep_poll() which unnecessarily forced
error return code when driver timed out waiting for TCP connect
request to complete

we hit a race and get stuck in the wait.

We should not check if the waitqueue is active

prepare to wait when we check for the waitqueue to
be active then we will miss each other and the

Stefan Richter 9cac00b8f0 firewire: cdev: fix information leak
A userspace client got to see uninitialized stack-allocated memory if it
specified an _IOC_READ type of ioctl and an argument size larger than
expected by firewire-core's ioctl handlers (but not larger than the
core's union ioctl_arg).

Fix this by clearing the requested buffer size to zero, but only at _IOR
ioctls.  This way, there is almost no runtime penalty to legitimate
ioctls.  The only legitimate _IOR is FW_CDEV_IOC_GET_CYCLE_TIMER with 12
or 16 bytes to memset.

[Another way to fix this would be strict checking of argument size (and
possibly direction) vs. command number.  However, we then need a lookup
table, and we need to allow for slight size deviations in case of 32bit
userland on 64bit kernel.]

The definition of struct fw_cdev_iso_packet seems to imply that the
header_length must be quadlet-aligned, and in fact, specifying an
unaligned header has never really worked when using multiple packet
structures, because the position of the next control word is computed by
rounding the header_length _down_, so the last one to three bytes of the
header would overlap the next control word.

To avoid this problem, check that the header length is properly aligned.

Johannes Berg 8b9fce7773 iwlwifi: work around bogus active chains detection
The current algorithm will sometimes "detect" that
more chains are enabled than are really present in
the device because, for unknown reasons, the ucode
sends up all-zeroes signal values.

The simplest way of solving this is to restrict the
active chains mask to the chains we know are really
present on the device.

This fixes a bug with some devices where, since sometimes
more chains are enabled than really present, the system would hang.

"len" hasn't been properly range checked so we shouldn't use it as an

Anton Blanchard 320718ee07 hvc_console: Fix race between hvc_close and hvc_remove
I don't claim to understand the tty layer, but it seems like hvc_open and
hvc_close should be balanced in their kref reference counting.

Right now we get a kref every call to hvc_open:

        if (hp->count++ > 0) {
                tty_kref_get(tty); <----- here
                spin_unlock_irqrestore(&hp->lock, flags);
                hvc_kick();
                return 0;
        } /* else count == 0 */

        tty->driver_data = hp;

        hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0

But hvc_close has:

        tty_kref_get(tty);

        if (--hp->count == 0) {
...
                /* Put the ref obtained in hvc_open() */
                tty_kref_put(tty);
...
        }

        tty_kref_put(tty);

Since the outside kref get/put balance we only do a single kref_put when
count reaches 0.

The patch below changes things to call tty_kref_put once for every
hvc_close call, and with that my machine boots fine.

As reported in <https://bugzilla.kernel.org/show_bug.cgi?id=15355>, r6040_
multicast_list currently crashes. This is due a wrong maximum of multicast
entries. This patch fixes the following issues with multicast:

- number of maximum entries if off-by-one (4 instead of 3)

- the writing of the hash table index is not necessary and leads to invalid
values being written into the MCR1 register, so the MAC is simply put in a non
coherent state

- when we exceed the maximum number of mutlticast address, writing the
broadcast address should be done in registers MID_1{L,M,H} instead of
MID_O{L,M,H}, otherwise we would loose the adapter's MAC address

Anton Blanchard 55ab3a1ff8 raw: fsync method is now required
Commit 148f948ba8 (vfs: Introduce new
helpers for syncing after writing to O_SYNC file or IS_SYNC inode) broke
the raw driver.

We now call through generic_file_aio_write -> generic_write_sync ->
vfs_fsync_range.  vfs_fsync_range has:

        if (!fop || !fop->fsync) {
                ret = -EINVAL;
                goto out;
        }

But drivers/char/raw.c doesn't set an fsync method.

We have two options: fix it or remove the raw driver completely.  I'm
happy to do either, the fact this has been broken for so long suggests it
is rarely used.

The patch below adds an fsync method to the raw driver.  My knowledge of
the block layer is pretty sketchy so this could do with a once over.

If we instead decide to remove the raw driver, this patch might still be
useful as a backport to 2.6.33 and 2.6.32.

Wolfram Sang 12765517d9 device_attributes: add sysfs_attr_init() for dynamic attributes
Made necessary by 6992f53349 ("sysfs: Use

Commit c2e13037e6 ("platform-drivers: move

section mismatch warnings in vesafb code.  Rather than converting all of
the annotations, do the obvious and revert the __init -> __devinit change,
and use the recommended (in that patch) alternative to calling
platform_driver_register(): vesafb depends on information obtained from by
kernel at boot time, cannot be a module, and no post-boot devices can ever
show up.

When ide taskfile access is being used (for example with hdparm --security
commands) and cfq scheduler is selected, the scheduler crashes on BUG in
cfq_put_request.

The reason is that the cfq scheduler is tracking counts of read and write
requests separately; the ide-taskfile subsystem allocates a read request and
then flips the flag to make it a write request. The counters in cfq will
mismatch.

This patch changes ide-taskfile to allocate the READ or WRITE request as
required and don't change the flag later.

This isn't an ideal solution but including slab.h directly from

Tejun Heo 445d211b0d libata: unlock HPA if device shrunk
Some BIOSes don't configure HPA during boot but do so while resuming.
This causes harddrives to shrink during resume making libata detach
and reattach them.  This can be worked around by unlocking HPA if old
size equals native size.

Add ATA_DFLAG_UNLOCK_HPA so that HPA unlocking can be controlled
per-device and update ata_dev_revalidate() such that it sets
ATA_DFLAG_UNLOCK_HPA and fails with -EIO when the above condition is
detected.

Tejun Heo 68b0ddb289 libata: disable NCQ on Crucial C300 SSD
Crucial said,

  Thank you for contacting us. We know that with our M225 line of SSDs
  you sometimes need to disable NCQ (native command queuing) to avoid
  just the type of errors you're seeing. Our recommendation for the
  M225 is to add libata.force=noncq to your Linux kernel boot options,
  under the kernel ATA library option.

  I have sent your feedback to the engineers working on the C300, and
  asked them to please pass it on to the firmware team. I have been
  notified that they are in the process of testing and finalizing a
  new firmware version, that you can expect to see released around the
  end of April. We’ll keep you posted as to when it will be available
  for download.

So, turn off NCQ on the drive w/ the current firmware revision.

On the control panel some of the keys could be used to turn on/off

operation difficult.

Chase Douglas 1638bca898 ACPI: Reduce ACPI resource conflict message to KERN_WARNING, printk cleanup
By default, ACPI resource conflict messages are logged at level
KERN_ERR. This is a rather high level for a message that is more a
warning than an indication of a real kernel error. Also, KERN_ERR level
messages can appear over some boot splash screens, and this message is
not serious enough to warrant such treatment. Thus, the log level has
been reduced to KERN_WARNING.

[lenb changed to KERN_WARNING rather than all the way to KERN_INFO]

Also, cleanup message to use %pR resource printing format.

- pcmcia_align() used a "start" variable twice. That's obviously a bad
  idea.

- pcmcia_common_resource() needs the current "start" parameter being
  passed, instead of res->start.

- pcmcia_common_resource() doesn't use the size and align parameters,
  so get rid of those.

Bjorn Helgaas 3162b6f0c5 PNPACPI: truncate _CRS windows with _LEN > _MAX - _MIN + 1
The ACPI spec (sec 6.4.3.5 in v4.0) requires that for Address Space Resource
Descriptors, _LEN <= _MAX - _MIN + 1 in all cases, but there are BIOSes that
violate this.  We experimentally determined that Windows truncates the
resource so it doesn't extend past _MAX, so let's do the same thing in
Linux.

I have a machine here that's sending 0xD1 notifications on the video
device once every second or so. I have no idea why (it's a prototype,
it may be broken), but sending KEY_UNKNOWN is unhelpful and results in
the console becoming unusable. Let's not report keys unless we have
something useful to say about them.

Bjorn Helgaas b7b30de53a ACPI: use _HID when supplied by root-level devices
Previously, we assumed the only Device object immediately below the root
was the \_SB Scope (which the ACPI CA treats as a Device), so we forced
the HID of all such objects to ACPI_BUS_HID ("LNXSYBUS").

However, there are DSDTs that supply root-level Device objects with _HIDs.
This patch makes us pay attention to those _HIDs and only add the synthetic
ACPI_BUS_HID for root-level objects that do not supply their own _HID.

For example, this DSDT: https://bugzilla.kernel.org/show_bug.cgi?id=15605
contains:

    Scope (_SB) {
	...
    }
    Device (AMW0) {
	Name (_HID, EisaId ("PNP0C14"))
	...
    }

and we should use "PNP0C14" for the AMW0 device, not "LNXSYBUS".
