ACPICA commit 9f7c3e148f440049615e2791d73b292f65692d7e

The most recent version of the IORT specification adds in a definition
for a subtable to describe SMMUv3 devices; there is already a subtable
for SMMUv1/v2 devices.

Add in the definition of the subtable, add in the code to compile it,
and add in a template for it.

30a3915385 cpufreq: intel_pstate: fix inconsistency in setting policy limits
When user sets performance policy using cpufreq interface, it is possible
that because of policy->max limits, the actual performance is still
limited. But the current implementation will silently switch the
policy to powersave and start using powersave limits. If user modifies
any limits using intel_pstate sysfs, this is actually changing powersave
limits.

The current implementation tracks limits under powersave and performance
policy using two different variables. When policy->max is less than
policy->cpuinfo.max_freq, only powersave limit variable is used.

This fix causes the performance limits variable to be used always when
the policy is performance.

6e3380488a Merge branch 'mv88e6131-hw-bridging-6185'
Vivien Didelot says:

====================
net: dsa: mv88e6131: HW bridging support for 6185

All packets passing through a switch of the 6185 family are currently all
directed to the CPU port. This means that port bridging is software driven.

To enable hardware bridging for this switch family, we need to implement the
port mapping operations, the FDB operations, and optionally the VLAN operations
(for 802.1Q and VLAN filtering aware systems).

However this family only has 256 FDBs indexed by 8-bit identifiers, opposed to
4096 FDBs with 12-bit identifiers for other families such as 6352. It also
doesn't have dedicated FID registers for ATU and VTU operations.

This patchset fixes these differences, and enable hardware bridging for 6185.

Changes v1 -> v2:
 - Describe the different numbers of databases and prefer a feature-based logic
   over the current ID/family-based logic.

26892ffc80 net: dsa: mv88e6131: enable hardware bridging
By adding support for bridge operations, FDB operations, and optionally
VLAN operations (for 802.1Q and VLAN filtering aware systems), the
switch bridges ports correctly, the CPU is able to populate the hardware
address databases, and thus hardware bridging becomes functional within
the 88E6185 family of switches.

f93dd042de net: dsa: mv88e6xxx: map destination addresses for 6185
The 88E6185 switch also has a MapDA bit in its Port Control 2 register.
When this bit is cleared, all frames are sent out to the CPU port.

Set this bit to rely on address databases (ATU) hits and direct frames
out of the correct ports, and thus allow hardware bridging.

dbd15b8f9c ixgbe: Place SWFW semaphore in known valid state at probe
It is possible on some HW that a system reset could occur when we are
holding the SWFW semaphore lock.  So next time the driver was loaded we
would see it incorrectly as locked. This patch will recover from that state
by: Attempting to acquire the semaphore and then regardless of whether or
not it was acquire we immediately release it. This will force us into
a known good state.

cb2b3edbec ixgbevf: Add support for generic Tx checksums
This patch adds support for generic Tx checksums to the ixgbevf driver.  It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.

In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
  MACLEN (maximum of 127), retrieved from:
		skb_network_offset()
  IPLEN  (maximum of 511), retrieved from:
		skb_checksum_start_offset() - skb_network_offset()
  TUCMD.L4T indicates offset and if checksum or crc32c, based on:
		skb->csum_offset

The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.

I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers.  In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

Fixes ttm on platforms like PPC460 where the CPU
is in 32-bit mode, but the physical addresses are
>32 bits.

53c43c5ca1 Revert "Staging: olpc_dcon: Remove obsolete driver"
This reverts commit 82ef33af9d.  It turns
out these machines are still out there, and the original patch broke
them.  So revert it, adding back the driver, so people's machines still
work properly.

c862cc9b70 bridge: Fix incorrect variable assignment on error path in br_sysfs_addbr
This fixes the incorrect variable assignment on error path in
br_sysfs_addbr for when the call to kobject_create_and_add
fails to assign the value of -EINVAL to the returned variable of
err rather then incorrectly return zero making callers think this
function has succeededed due to the previous assignment being
assigned zero when assigning it the successful return value of
the call to sysfs_create_group which is zero.

f51bdc236b ravb: Add dma queue interrupt support
This patch supports the following interrupts.

- One interrupt for multiple (timestamp, error, gPTP)
- One interrupt for emac
- Four interrupts for dma queue (best effort rx/tx, network control rx/tx)

This patch improve efficiency of the interrupt handler by adding the
interrupt handler corresponding to each interrupt source described
above. Additionally, it reduces the number of times of the access to
EthernetAVB IF.
Also this patch prevent this driver depends on the whim of a boot loader.
