3fc929e2d6 net/mlx4_core: Fix number of EQs used in ICM initialisation
In SRIOV mode, the number of EQs used when computing the total ICM size
was incorrect.

To fix this, we do the following:
1. We add a new structure to mlx4_dev, mlx4_phys_caps, to contain physical HCA
   capabilities.  The PPF uses the phys capabilities when it computes things
   like ICM size.

   The dev_caps structure will then contain the paravirtualized values, making
   bookkeeping much easier in SRIOV mode. We add a structure rather than a
   single parameter because there will be other fields in the phys_caps.

   The first field we add to the mlx4_phys_caps structure is num_phys_eqs.

2. In INIT_HCA, when running in SRIOV mode, the "log_num_eqs" parameter
   passed to the FW is the number of EQs per VF/PF; each function (PF or VF)
   has this number of EQs available.

   However, the total number of EQs which must be allowed for in the ICM is
   (1 << log_num_eqs) * (#VFs + #PFs).  Rather than compute this quantity,
   we allocate ICM space for 1024 EQs (which is the device maximum
   number of EQs, and which is the value we place in the mlx4_phys_caps structure).

   For INIT_HCA, however, we use the per-function number of EQs as described
   above.

ff413195e8 thinkpad-acpi: fix issuing duplicated key events for brightness up/down
The tp_features.bright_acpimode will not be set correctly for brightness
control because ACPI_VIDEO_HID will not be located in ACPI. As a result,
a duplicated key event will always be sent. acpi_video_backlight_support()
is sufficient to detect standard ACPI brightness control.

bc7ab495c7 xo1-rfkill: only act when blocked state is changed
The XO-1 rfkill driver should only send EC commands when changing
between blocked/unblocked state.

The rfkill switch is asked to be unblocked on every resume (even when
the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET
command here upsets the resume sequence of the libertas driver. Adding
the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume
behaviour.

The rfkill state is maintained by the hardware over suspend/resume
so no extra consideration is needed here.

145047de99 drivers/x86: mark const init data with __initconst instead of __initdata
As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with

	error: $variablename causes a section type conflict

because a section containing const variables is marked read only and so
cannot contain non-const variables.

c31931088f Btrfs: fix tree mod log rewinded level and rewinding of moved keys
When we rewind REMOVE_WHILE_FREEING operations, there's code that allocates
a fresh buffer instead of cloning the old one. Setting that buffer's level
correctly was missing in this case.

When rewinding a MOVE_KEYS operation, btrfs_node_key_ptr_offset(slot) was
missing for memmove_extent_buffer()'s arguments.
