83aefbb887 drm: Add drm_connector_for_each_possible_encoder()
Add a convenience macro for iterating connector->encoder_ids[].
Isolates the users from the implementation details.

Note that we don't seem to pass the file_priv down to drm_encoder_find()
because encoders apparently don't get leased. No idea why
drm_encoder_finc() even takes the file_priv actually.

Also use ARRAY_SIZE() when populating the array to avoid spreading
knowledge about the array size all over.

v2: Hide the drm_encoder_find() in the macro, and
    rename the macro appropriately (Daniel)
v3: Fix kernel docs (Daniel)

With the fb-helper no longer relying on the non-atomic .best_encoder()

0d99889109 drm/fb-helper: Eliminate the .best_encoder() usage
Instead of using the .best_encoder() hook to figure out whether a given
connector+crtc combo will work, let's instead do what userspace does and
just iterate over all the encoders for the connector, and then check
each crtc against each encoder's possible_crtcs bitmask.

v2: Avoid oopsing on NULL encoders (Daniel)

1c7c5fd916 drm/vkms: Introduce basic VKMS driver
This patch introduces Virtual Kernel Mode-Setting (VKMS) driver. It
creates a very basic kms driver with 1 crtc/encoder/connector/plane.

VKMS driver would be useful for testing, or for running X (or similar)
on headless machines and be able to still use the GPU. Thus it enables
a virtual display without the need for hardware display capability.

2c83a726d6 drm/etnaviv: bring back progress check in job timeout handler
When the hangcheck handler was replaced by the DRM scheduler timeout
handling we dropped the forward progress check, as this might allow
clients to hog the GPU for a long time with a big job.

It turns out that even reasonably well behaved clients like the
Armada Xorg driver occasionally trip over the 500ms timeout. Bring
back the forward progress check to get rid of the userspace regression.

We would still like to fix userspace to submit smaller batches
if possible, but that is for another day.

a9ba23d48d ipv6: make ipv6_renew_options() interrupt/kernel safe
At present the ipv6_renew_options_kern() function ends up calling into
access_ok() which is problematic if done from inside an interrupt as
access_ok() calls WARN_ON_IN_IRQ() on some (all?) architectures
(x86-64 is affected).  Example warning/backtrace is shown below:

  ...

While not present in the backtrace, ipv6_renew_option() ends up calling
access_ok() via the following chain:

  access_ok()
  _copy_from_user()
  copy_from_user()
  ipv6_renew_option()

The fix presented in this patch is to perform the userspace copy
earlier in the call chain such that it is only called when the option
data is actually coming from userspace; that place is
do_ipv6_setsockopt().  Not only does this solve the problem seen in
the backtrace above, it also allows us to simplify the code quite a
bit by removing ipv6_renew_options_kern() completely.  We also take
this opportunity to cleanup ipv6_renew_options()/ipv6_renew_option()
a small amount as well.

This patch is heavily based on a rough patch by Al Viro.  I've taken
his original patch, converted a kmemdup() call in do_ipv6_setsockopt()
to a memdup_user() call, made better use of the e_inval jump target in
the same function, and cleaned up the use ipv6_renew_option() by
ipv6_renew_options().

2e41c380d1 Merge branch 'devlink-Add-configuration-parameters-support'
Moshe Shemesh says:

====================
Add configuration parameters support

Add configuration parameters setting through devlink.
Each device registers supported configuration parameters table.
Each parameter can be either generic or driver specific.
The user can retrieve data on these parameters by "devlink param show"
command and can set new value to a parameter by "devlink param set"
command.
The parameters can be set in different configuration modes:
  runtime - set while driver is running, no reset required.
  driverinit - applied while driver initializes, requires restart
               driver by devlink reload command.
  permanent - written to device's non-volatile memory, hard reset required.

The patches at the end of the patchset introduce few params that are using
the introduced infrastructure on mlx4 and bnxt.

Command examples and output:

pci/0000:81:00.0:
  name internal_error_reset type generic
    values:
      cmode runtime value true
      cmode driverinit value true
  name max_macs type generic
    values:
      cmode driverinit value 128
  name enable_64b_cqe_eqe type driver-specific
    values:
      cmode driverinit value true
  name enable_4k_uar type driver-specific
    values:
      cmode driverinit value false

pci/0000:81:00.0:
  name internal_error_reset type generic
    values:
      cmode runtime value false
      cmode driverinit value true

bd1b51dc66 mlx4: Add mlx4 initial parameters table and register it
Create initial parameters table for mlx4.
The table consists of two generic parameters and two driver-specific
parameters.
Generic:
  internal_err_reset - Enable reset device on internal errors. This
  parameter can be configured on mlx4 either on runtime or during driver
  initialization.
  max_macs - Max number of MACs per ETH port. For mlx4 this parameter
  value range is between 1 and 128. This parameter can be configured on
  mlx4 only during driver initialization.
Driver specific:
  enable_64b_cqe_eqe - Enable 64 byte CQEs/EQEs when the FW supports it.
  This parameter can be configured on mlx4 only during driver
  initialization.
  enable_4k_uar - Enable using 4K UAR. This parameter can be configured on
  mlx4 only during driver initialization.

Register the parameters table on mlx4_init_one() and unregister on
mlx4_remove_one().

Add functions to register and unregister the driver supported
configuration parameters table.
For each parameter registered, the driver should fill all the parameter's
fields. In case the only supported configuration mode is "driverinit"
the parameter's get()/set() functions are not required and should be set
to NULL, for any other configuration mode, these functions are required
and should be set by the driver.
