Pull ACPI and power management updates from Rafael Wysocki:
"ACPICA is the leader this time (63 commits), followed by cpufreq (28
commits), devfreq (15 commits), system suspend/hibernation (12
commits), ACPI video and ACPI device enumeration (10 commits each).
We have no major new features this time, but there are a few
significant changes of how things work. The most visible one will
probably be that we are now going to create platform devices rather
than PNP devices by default for ACPI device objects with _HID. That
was long overdue and will be really necessary to be able to use the
same drivers for the same hardware blocks on ACPI and DT-based systems
going forward. We're not expecting fallout from this one (as usual),
but it's something to watch nevertheless.
The second change having a chance to be visible is that ACPI video
will now default to using native backlight rather than the ACPI
backlight interface which should generally help systems with broken
Win8 BIOSes. We're hoping that all problems with the native backlight
handling that we had previously have been addressed and we are in a
good enough shape to flip the default, but this change should be easy
enough to revert if need be.
In addition to that, the system suspend core has a new mechanism to
allow runtime-suspended devices to stay suspended throughout system
suspend/resume transitions if some extra conditions are met
(generally, they are related to coordination within device hierarchy).
However, enabling this feature requires cooperation from the bus type
layer and for now it has only been implemented for the ACPI PM domain
(used by ACPI-enumerated platform devices mostly today).
Also, the acpidump utility that was previously shipped as a separate
tool will now be provided by the upstream ACPICA along with the rest
of ACPICA code, which will allow it to be more up to date and better
supported, and we have one new cpuidle driver (ARM clps711x).
The rest is improvements related to certain specific use cases,
cleanups and fixes all over the place.
Specifics:
- ACPICA update to upstream version 20140424. That includes a number
of fixes and improvements related to things like GPE handling,
table loading, headers, memory mapping and unmapping, DSDT/SSDT
overriding, and the Unload() operator. The acpidump utility from

Here is the big USB driver pull request for 3.16-rc1.
Nothing huge here, but lots of little things in the USB core, and in
lots of drivers. Hopefully the USB power management will be work better
now that it has been reworked to do per-port power control dynamically.
There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
is finally gone now that everything has been converted over to the
dynamic debug inteface, the last hold-out drivers were cleaned up and
the config option removed. There were also other minor things all
through the drivers/usb/ tree, the shortlog shows this pretty well.
All have been in linux-next, including the very last patch, which came
from linux-next to fix a build issue on some platforms.

Each iPad model has a different product id, this patch adds support for iPad 2
(pid 0x12a2) and iPad 3 (pid 0x12a6). Note that iPad 2 must be jailbroken and a
third-party app must be used for tethering to work. On iPad 3, tethering works
out of the box (assuming your ISP is nice).

Now it is not possible to set mtu to team device which has a port
enslaved to it. The reason is that when team_change_mtu() calls
dev_set_mtu() for port device, notificator for NETDEV_PRECHANGEMTU
event is called and team_device_event() returns NOTIFY_BAD forbidding
the change. So fix this by returning NOTIFY_DONE here in case team is
changing mtu in team_change_mtu().

Reset the GIDs assigned to a VF in the port RoCE GID table when
that guest goes down (either crashes or goes down cleanly).
As part of this fix, we refactor the RoCE gid table driver copy,
moving it to the mlx4_port_info structure (together with the MAC
and VLAN tables).
As with the MAC and VLAN tables, we now use a mutex per port
for the GID table so that modifying the driver copy and
modifying the firmware copy of a port GID table becomes an
atomic operation (thus avoiding driver-copy/FW-copy mismatches).

Fixes: 99ec41d0a4 ("mlx4: Add infrastructure for selecting VFs to enable QP0 via MLX proxy QPs")
Signed-off-by: Roland Dreier <roland@purestorage.com>
This commit adds the sysfs interface for enabling QP0 on VFs for
selected VF/port.
By default, no VFs are enabled for QP0 operation.
To enable QP0 operation on a VF/port, under
/sys/class/infiniband/mlx4_x/iov/<b:d:f>/ports/x there are two new entries:
- smi_enabled (read-only). Indicates whether smi is currently
enabled for the indicated VF/port
- enable_smi_admin (rw). Used by the admin to request that smi
capability be enabled or disabled for the indicated VF/port.
0 = disable, 1 = enable.
The requested enablement will occur at the next reset of the
VF (e.g. driver restart on the VM which owns the VF).

This commit adds the infrastructure for enabling selected VFs to
operate SMI (QP0) MADs without restriction.
Additionally, for these enabled VFs, their QP0 proxy and tunnel QPs
are MLX QPs. As such, they operate over VL15. Therefore, they are
not affected by "credit" problems or changes in the VLArb table (which
may shut down VL0).
Non-enabled VFs may only create UD proxy QP0 qps (which are forced by
the hypervisor to send packets using the q-key it assigns and places
in the qp-context). Thus, non-enabled VFs will not pose a security
risk. The hypervisor discards any privileged MADs it receives from
these non-enabled VFs.
By default, all VFs are NOT enabled, and must explicitly be enabled
by the administrator.
The sysfs interface which operates the VF enablement infrastructure
is provided in the next commit.

Currently, VFs in SRIOV VFs are denied QP0 access. The main reason
for this decision is security, since Subnet Management Datagrams
(SMPs) are not restricted by network partitioning and may affect the
physical network topology. Moreover, even the SM may be denied access
from portions of the network by setting management keys unknown to the
SM.
However, it is desirable to grant SMI access to certain privileged
VFs, so that certain network management activities may be conducted
within virtual machines instead of the hypervisor.
This commit does the following:
1. Create QP0 tunnel QPs for all VFs.
2. Discard SMI mads sent-from/received-for non-privileged VFs in the
hypervisor MAD multiplex/demultiplex logic. SMI mads from/for
privileged VFs are allowed to pass.
3. MAD_IFC wrapper changes/fixes. For non-privileged VFs, only
host-view MAD_IFC commands are allowed, and only for SMI LID-Routed
GET mads. For privileged VFs, there are no restrictions.
This commit does not allow privileged VFs as yet. To determine if a VF
is privileged, it calls function mlx4_vf_smi_enabled(). This function
returns 0 unconditionally for now.
The next two commits allow defining and activating privileged VFs.

As not every CAN driver supports and initializes the led triggers, checking for

not enough.
This patch adds a check when CONFIG_CAN_LEDS is enabled and the driver does not

ALB learning packets are currentlyalways sent using the slave mac
address for all vlans configured on top of bond. This is not always
correct, as vlans may change their mac address.
This patch introduced a concept of strict matching where the
source of learning packets can either strictly match the address
passed in, or it can determine a more correct address to use.
There are 3 casese to consider:
1) Switchover. In this case, we have a new active slave and we need
tell the switch about all addresses available on the slave.
2) Monitor. We'll periodically refresh learning info for all slaves.
In this case, we refresh all addresses for current active, and just
the slave address for other slaves.
3) Teaching of disabled adddress. This happens as part of the
failover and in this case, we alwyas to use just the address
provided.

Prior to commit fbd929f2dc
bonding: support QinQ for bond arp interval
the arp monitoring code allowed for proper detection of devices
stacked on top of vlans. Since the above commit, the
code can still detect a device stacked on top of single
vlan, but not a device stacked on top of Q-in-Q configuration.
The search will only set the inner vlan tag if the route
device is the vlan device. However, this is not always the
case, as it is possible to extend the stacked configuration.
With this patch it is possible to provision devices on
top Q-in-Q vlan configuration that should be used as
a source of ARP monitoring information.
For example:
ip link add link bond0 vlan10 type vlan proto 802.1q id 10
ip link add link vlan10 vlan100 type vlan proto 802.1q id 100
ip link add link vlan100 type macvlan
Note: This patch limites the number of stacked VLANs to 2,
just like before. The original, however had another issue
in that if we had more then 2 levels of VLANs, we would end
up generating incorrectly tagged traffic. This is no longer
possible.

When the NAPI budget was not all used, xenvif_poll() would call
napi_complete() /after/ enabling the interrupt. This resulted in a
race between the napi_complete() and the napi_schedule() in the
interrupt handler. The use of local_irq_save/restore() avoided by
race iff the handler is running on the same CPU but not if it was
running on a different CPU.
Fix this properly by calling napi_complete() before reenabling
interrupts (in the xenvif_napi_schedule_or_enable_irq() call).

"Alex fixes the scan by disabling the fragmented scan. David prevents
scan offload while associated, the firmware seems not to like it. I

that can happen if we load the driver and our ISR gets called because
the interrupt line is shared. The fix has been tested by the reporter."
