In the original code we used "j" as an iterator but we used "i" as an
index.
- for (j = 0; j < i; j++)
- device_remove_file(&connector->kdev,
- &connector_attrs[i]);
Smatch complained about that because "i" was potentially passed the end of
the array. Which makes sense if we should be using "j" there.
I also thought that we should remove the files for &connector_attrs_opt1
but to do that I had to add separate iterators for &connector_attrs and
&connector_attrs_opt1.

Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().
The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).
This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.
This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.
Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.

Bill Gatliff reported the following bug when using the irq_chip facility
of the pca953x driver on a PPC platform:
BUG: scheduling while atomic: insmod/1530/0x00000002
He traced it back to an i2c transaction in pca953x_irq_set_type(), which
can be called with interrupt disabled (from __setup_irq()). As the i2c
controller can sleep while sending a message, this qualifies as a bad
idea.
This patch moves the i2c transaction to pca953x_irq_bus_sync_unlock(),
where it is actually safe to send an i2c message.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock.
The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while
changing the vlgrp. The call also stops the cnic driver which sleeps
while the bond->lock is held and cause the warning.
This code path only needs to stop the NAPI rx handling while we are
changing the vlgrp. Since no reset is going to occur, there is no need
to stop cnic in this case. By adding a parameter to bnx2_netif_stop()
to skip stopping cnic, we can avoid the warning.

It has been reported that under certain heavy traffic conditions in MSI-X
mode, the driver can lose an MSI-X vector causing all packets in the
associated rx/tx ring pair to be dropped. The problem is caused by
the chip dropping the write to unmask the MSI-X vector by the kernel
(when migrating the IRQ for example).
This can be prevented by increasing the GRC timeout value for these
register read and write operations.

Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect. 82571 and 82572 should always disable L1. For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1. This allows for some
parts to enable L1 in certain configurations leading to better power
savings.
Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.

We copy some strings into "event" but we leave the space after the NULL
terminators uninitialized. Later in acpi_bus_receive_event() we copy
the whole struct to another buffer with memcpy(). If the new buffer is
stored on the stack, kmemcheck prints a warning about the unitialized
space after the NULL terminators.
It's true that the space is uninitialized, but it's harmless. The
buffer is only used in acpi_system_read_event() and we don't read past
the NULL terminators.
This patch changes the kmalloc() to kzalloc() so that we initialize the
memory and silence the kmemcheck warning.

This is a standalone version of VMware Balloon driver. Ballooning is a
technique that allows hypervisor dynamically limit the amount of memory
available to the guest (with guest cooperation). In the overcommit
scenario, when hypervisor set detects that it needs to shuffle some
memory, it instructs the driver to allocate certain number of pages, and
the underlying memory gets returned to the hypervisor. Later hypervisor
may return memory to the guest by reattaching memory to the pageframes and
instructing the driver to "deflate" balloon.
We are submitting a standalone driver because KVM maintainer (Avi Kivity)
expressed opinion (rightly) that our transport does not fit well into
virtqueue paradigm and thus it does not make much sense to integrate with
virtio.
There were also some concerns whether current ballooning technique is the
right thing. If there appears a better framework to achieve this we are
prepared to evaluate and switch to using it, but in the meantime we'd like
to get this driver upstream.
We want to get the driver accepted in distributions so that users do not
have to deal with an out-of-tree module and many distributions have
"upstream first" requirement.
The driver has been shipping for a number of years and users running on
VMware platform will have it installed as part of VMware Tools even if it
will not come from a distribution, thus there should not be additional
risk in pulling the driver into mainline. The driver will only activate
if host is VMware so everyone else should not be affected at all.

Description of patch:
---------------------
This is a patch for the EFI framebuffer driver to enable the framebuffer
of the NVIDIA 9400M as found in MacBook Pro (MBP) 5,1 and up. The
framebuffer of the NVIDIA graphic cards are located at the following
addresses in memory:
9400M: 0xC0010000
9600M GT: 0xB0030000
The patch delivered right here only provides the memory location of the
framebuffer of the 9400M device. The 9600M GT is not covered. It is
assumed that the 9400M is used when powered up the MBP.
The information which device is currently powered and in use is stored in
the 64 bytes large EFI variable "gpu-power-prefs". More specifically,
byte 0x3B indicates whether 9600M GT (0x00) or 9400M (0x01) is online.
The PCI bus IDs are the following:
9400M: PCI 03:00:00
9600M GT: PCI 02:00:00
The EFI variables can be easily read-out and manipulated with "rEFIt", an
MBP specific bootloader tool. For more information on how handle rEFIt
and EFI variables please consult "http://refit.sourceforge.net" and

IMPORTANT NOTE: The information on how to activate the 9400M device given
at "ubuntuforums.org" is not correct, since it states
gpu-power-prefs[0x3B] = 0x00 -> 9400M (PCI 02:00:00)
gpu-power-prefs[0x3B] = 0x01 -> 9600M GT (PCI 03:00:00)
Actually, the assignment of the values and the PCI bus IDs are swapped.
Suggestions:
------------
To cover framebuffers of both 9400M and 9600M GT, I would suggest to
implement a conditional on "gpu-power-prefs". Depending on the value of
byte 0x3B, the according framebuffer is selected. However, this requires
kernel access to the EFI variables.

We must tell GCC to use even register for variable passed to ldrd
instruction. Without this patch GCC 4.2.1 puts this variable to r2/r3 on
EABI and r3/r4 on OABI, so force it to r2/r3. This does not change
anything when EABI and OABI compilation works OK.
Without this patch and with OABI I get:

My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was
testing a whole set of patches together and missed a conversion to the
new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake
965 class chips. Fortunately, the fix is trivial and has been tested.
Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or
we'll end up reading the wrong graphics memory, likely causing hangs,
crashes, or worse.

This patch (as1370) fixes a bug in the USB runtime power management
code. When a driver claims an interface, it doesn't expect to need to
call usb_autopm_get_interface() or usb_autopm_put_interface() for
runtime PM to work. Runtime PM can be controlled by the driver's
primary interface; the additional interfaces it claims shouldn't
interfere. As things stand, the claimed interfaces will prevent the
device from autosuspending.
To fix this problem, the patch sets interfaces to the suspended state
when they are claimed.
Also, although in theory this shouldn't matter, the patch changes the
suspend code so that interfaces are suspended in reverse order from
detection and resuming. This is how the PM core works, and we ought
to use the same approach.

This patch (as1363) changes the way USB remote wakeup is handled
during system sleeps. It won't be enabled unless an interface driver
specifically needs it. Also, it won't be enabled during the FREEZE or
QUIESCE phases of hibernation, when the system doesn't respond to
wakeup events anyway. Finally, if the device is already
runtime-suspended with remote wakeup enabled, but wakeup is supposed
to be disabled for the system sleep, the device gets woken up so that
it can be suspended again with the proper wakeup setting.
This will fix problems people have reported with certain USB webcams
that generate wakeup requests when they shouldn't, and as a result
cause system suspends to fail. See

The reipl device information is passed from the kernel to zfcpdump
using a pointer in the lowcore (0xe00) that points to the reipl
information Currently if that pointer is not zero, we copy the reipl
information. If the pointer is not initialized and points outside
the accessible memory, it can happen that the memory copy fails.
In that case we currently stop the initialization of zcore which leads
to a failing kernel dump. The correct behavior is to disable the reipl
after dump and continue with zcore intialization.

The new type of touchpads can be detected via a new query command

When the device is detected, the driver now reports only the left
button as the supported buttons so that X11 driver can detect that
the device is Clickpad. A Clickpad device gives the button events
only as the middle button. The kernel driver morphs to the left

Current code is definitely crap: Largest pitch allowed spills into
the TILING_Y bit of the fence registers ... :(
I've rewritten the limits check under the assumption that 3rd gen hw
has a 3d pitch limit of 8kb (like 2nd gen). This is supported by an
otherwise totally misleading XXX comment.
This bug mostly resulted in tiling-corrupted pixmaps because the kernel
allowed too wide buffers to be tiled. Bug brought to the light by the
xf86-video-intel 2.11 release because that unconditionally enabled
tiling for pixmaps, relying on the kernel to check things. Tiling for
the framebuffer was not affected because the ddx does some additional
checks there ensure the buffer is within hw-limits.
v2: Instead of computing the value that would be written into the
hw fence registers and then checking the limits simply check whether
the stride is above the 8kb limit. To better document the hw, add
some WARN_ONs in i915_write_fence_reg like I've done for the i830
case (using the right limits).

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.]

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.

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).

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.

This is a fix for bug 572201 @ bugs.debian.org
This patch fixes the TX_LIMIT feature flag. The previous logic check
for TX_LIMIT2 also took into account a device that only had TX_LIMIT
set.
