e46215fe67 Revert "Revert "Staging: rtl8812ae: remove modules field of rate_control_ops""
This reverts commit 161d785554.

Reversal of fortune -- I thought this was going to be resolved by other
means, but that hasn't materialized.  Plus, apparently we now care more
than I realized about not breaking staging drivers...

4b0c82529b drm/vmwgfx: Fix a surface reference corner-case in legacy emulation mode
If running on a gb-object capable device with a non-gb capable surface
exporter (X server) and a gb capable surface referencing client (GL driver),
the referencing client expects to find a shareable backing buffer attached to
the surface at reference time. This may not be the case if the surface has
not yet been validated. This would cause the surface reference IOCTL to
return an error.

  One of the resource allocation changes from the merge window is broken

  (mostly pre-2008 machines), so there's a fix for that.

  The INTx enable change we put in after the merge window turned out to
  break pciehp because we re-enable INTx on the hotplug bridge, which

c4e1acbb35 ACPI / init: Invoke early ACPI initialization later
Commit 73f7d1ca32 (ACPI / init: Run acpi_early_init() before
timekeeping_init()) optimistically moved the early ACPI initialization
before timekeeping_init(), but that didn't work, because it broke fast
TSC calibration for Julian Wollrath on Thinkpad x121e (and most likely
for others too).  The reason is that acpi_early_init() enables the SCI
and that interferes with the fast TSC calibration mechanism.

Thus follow the original idea to execute acpi_early_init() before
efi_enter_virtual_mode() to help the EFI people for now and we can
revisit the other problem that commit 73f7d1ca32 attempted to
address in the future (if really necessary).

2ed99e39cb cpufreq: Skip current frequency initialization for ->setpolicy drivers
After commit da60ce9f2f (cpufreq: call cpufreq_driver->get() after
calling ->init()) __cpufreq_add_dev() sometimes fails for CPUs handled
by intel_pstate, because that driver may return 0 from its ->get()
callback if it has not run long enough to collect enough samples on the
given CPU.  That didn't happen before commit da60ce9f2f which added
policy->cur initialization to __cpufreq_add_dev() to help reduce code
duplication in other cpufreq drivers.

However, the code added by commit da60ce9f2f need not be executed
for cpufreq drivers having the ->setpolicy callback defined, because
the subsequent invocation of cpufreq_set_policy() will use that
callback to initialize the policy anyway and it doesn't need
policy->cur to be initialized upfront.  The analogous code in
cpufreq_update_policy() is also unnecessary for cpufreq drivers
having ->setpolicy set and may be skipped for them as well.

Since intel_pstate provides ->setpolicy, skipping the upfront
policy->cur initialization for cpufreq drivers with that callback
set will cover intel_pstate and the problem it's been having after
commit da60ce9f2f will be addressed.

Fixes: da60ce9f2f (cpufreq: call cpufreq_driver->get() after calling ->init())

Using dev_kfree_skb_any for functions called in multiple contexts

This patchset should be an uncontroversial set of changes to change
dev_kfree_skb to dev_kfree_skb_any for code paths that are called in

this code gets called in multiple contexts.

There is more coming but these changes are a good starting place, and
stand on their own.

Since the last round changes to the rx path have been removed netpoll
will changed to avoid that.

48291c22b7 be2net: Fix vlans_added counter
When a VLAN is added by user, adapter->vlans_added is incremented.
But if the VLAN is already programmed in HW, driver ends up
incrementing the counter wrongly.

Increment the counter only if VLAN is not already programmed in the HW.

a5243dabb9 be2net: Create multiple TXQs on RSS capable multi-channel BE3-R interfaces
Currently the driver creates only a single TXQ on any BE3-R multi-channel
interface.
This patch changes this and creates multiple TXQs on RSS-capable multi-channel
BE3-R interfaces. This change helps improve the TX pps performance on the
affected interface.

mlx4 fixes

These short series fixes two bugs related to the vxlan support and a
missing req module call for the IB driver which is needed to support
IB/RDMA over Ethernet.

the IPoIB flow-steering device capability and fix small typo.

The vxlan cap value wasn't fully handled when a conflict was resolved
between MLX4_DEV_CAP_FLAG2_DMFS_IPOIB coming from the IB tree to
MLX4_DEV_CAP_FLAG2_VXLAN_OFFLOADS coming from net-next.

====================
mlx4: Add SRIOV support for RoCE

This series adds SRIOV support for RoCE (RDMA over Ethernet) to the mlx4 driver.

The patches are against net-next, as of commit 2d8d40a "pkt_sched: fq:
do not hold qdisc lock while allocating memory"

changes from V1:
 - addressed feedback from Dave on patch #3 and changed get_real_sgid_index()
   to be called fill_in_real_sgid_index() and be a void  function.
 - removed some checkpatch warnings on long lines

changes from V0:
  - always check the return code of mlx4_get_roce_gid_from_slave().
    The call we fixed is introduced in patch #1 and later removed by
    patch #3 that allows guests to have multiple GIDS. The 1..3
    separation was done for proper division of patches to logical changes.

aa9a2d51a3 mlx4: Activate RoCE/SRIOV
To activate RoCE/SRIOV, need to remove the following:
1. In mlx4_ib_add, need to remove the error return preventing
   initialization of a RoCE port under SRIOV.
2. In update_vport_qp_params (in resource_tracker.c) need to remove
   the error return when a RoCE RC or UD qp is detected.
   This error return causes the INIT-to-RTR qp transition to fail
   in the wrapper function under RoCE/SRIOV.
