The ECC bit positions that describe whether the ECC interrupt is for
Tx, Rx or descriptor memory and whether the it is a single correctable
or double detected error were defined in incorrectly (reversed order).
Fix the bit position definitions for these settings so that the proper
ECC handling is performed.

compile-testing fails when QCOM_SMD is a loadable module:

This clarifies the dependency to allow compile-testing only when
SMD is completely disabled, otherwise the dependency on QCOM_SMD
will make sure we can link against it.

Commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset")
removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and
bcmgenet_internal_phy_setup() functions. In so doing it broke the reset
of the internal PHY devices used by the GENETv1-GENETv3 which required
this reset before the UniMAC was enabled. It also broke the internal
GPHY devices used by the GENETv4 because the config_init that installed
the AFE workaround was no longer occurring after the reset of the GPHY
performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup().
In addition the code in bcmgenet_internal_phy_setup() related to the
"enable APD" comment goes with the bcmgenet_mii_reset() so it should
have also been removed.
Commit bd4060a6108b ("net: bcmgenet: Power on integrated GPHY in
bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the
bcmgenet_power_up() function, but failed to remove it from the
bcmgenet_internal_phy_setup() function. Had it done so, the
bcmgenet_internal_phy_setup() function would have been empty and could
have been removed at that time.
Commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on")
was submitted to correct the functional problems introduced by
commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset"). It
was included in v4.4 and made available on 4.3-stable. Unfortunately,
it didn't fully revert the commit because this bcmgenet_mii_reset()
doesn't apply the soft reset to the internal GPHY used by GENETv4 like
the previous one did. This prevents the restoration of the AFE work-
arounds for internal GPHY devices after the bcmgenet_phy_power_set() in
bcmgenet_internal_phy_setup().
This commit takes the alternate approach of removing the unnecessary
bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3
so that when bcmgenet_mii_reset() was restored it should have only gone
into bcmgenet_power_up(). This will avoid the problems while also
removing the redundancy (and hopefully some of the confusion).

The extended device socket cannot turn on/off while system is running.
So when system boots up and the device is not power on, the fjes driver
does not need be loaded.

The fjes driver is used only by FUJITSU servers and almost of all
servers in the world never use it. But currently if ACPI PNP0C02
is defined in the ACPI table, the following message is always shown:
"FUJITSU Extended Socket Network Device Driver - version 1.2
- Copyright (c) 2015 FUJITSU LIMITED"
The message makes users confused because there is no reason that
the message is shown in other vendor servers.
To avoid the confusion, the patch adds a check that the server
has a extended socket device or not.

RX packets statistics ('rx_packets' counter) used to count LRO packets
as one, even though it contains multiple segments.
This patch will increment the counter by the number of segments, and
align the driver with the behavior of other drivers in the stack.
Note that no information is lost in this patch due to 'rx_lro_packets'
counter existence.
Before, ethtool showed:

This was added to allow the TC offloading code to identify offloading
encap/decap vxlan rules.
The VF reps are effectively related to the same mlx5 PCI device as the
PF. Since the kernel invokes the (say) delete ndo for each netdev, the
FW erred on multiple vxlan dst port deletes when the port was deleted
from the system.
We fix that by keeping the registration to be carried out only by the
PF. Since the PF serves as the uplink device, the VF reps will look
up a port there and realize if they are ok to offload that.
Tested:
<SETUP VFS>
<SETUP switchdev mode to have representors>
ip link add vxlan1 type vxlan id 44 dev ens5f0 dstport 9999
ip link set vxlan1 up
ip link del dev vxlan1

Changing the eswitch inline mode can potentially cause already configured
flows not to match the policy. E.g. set policy L4, add some L4 rules,
set policy to L2 --> bad! Hence we disallow it.

inline mode changes if this isn't zero.

The dependency is reversed: cpsw and netcp call into cpts,
but cpts depends on the other two in Kconfig. This can lead
to cpts being a loadable module and its callers built-in:

As a workaround, I'm introducing another Kconfig symbol to
control the compilation of cpts, while making the actual
module controlled by a silent symbol that is =y when necessary.

The introduction of reserved regions has left a couple of rough edges
which we could do with sorting out sooner rather than later. Since we
are not yet addressing the potential dynamic aspect of software-managed
reservations and presenting them at arbitrary fixed addresses, it is
incongruous that we end up displaying hardware vs. software-managed MSI
regions to userspace differently, especially since ARM-based systems may
actually require one or the other, or even potentially both at once,
(which iommu-dma currently has no hope of dealing with at all). Let's
resolve the former user-visible inconsistency ASAP before the ABI has
been baked into a kernel release, in a way that also lays the groundwork
for the latter shortcoming to be addressed by follow-up patches.
For clarity, rename the software-managed type to IOMMU_RESV_SW_MSI, use
IOMMU_RESV_MSI to describe the hardware type, and document everything a
little bit. Since the x86 MSI remapping hardware falls squarely under
this meaning of IOMMU_RESV_MSI, apply that type to their regions as well,
so that we tell the same story to userspace across all platforms.
Secondly, as the various region types require quite different handling,
and it really makes little sense to ever try combining them, convert the
bitfield-esque #defines to a plain enum in the process before anyone
gets the wrong impression.

For some unknown reasons, in some cases, FLPD cache invalidation doesn't
work properly with SYSMMU v5 controllers found in Exynos5433 SoCs. This
can be observed by a firmware crash during initialization phase of MFC

enabled. To workaround this issue perform a full TLB/FLPD invalidation

With the new more strict ACPI gpio code the dsdt's IoRestriction
flags are honored on gpiod_get, but in some dsdt's it is wrong,
so explicitly call gpiod_direction_input on the id gpio if
necessary.
This fixes the following errors when the int3496 code is used
together with the new more strict ACPI gpio code:
[ 2382.484415] gpio gpiochip1: (INT33FF:01): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ
[ 2382.484425] gpio gpiochip1: (INT33FF:01): unable to lock HW IRQ 3 for IRQ
[ 2382.484429] genirq: Failed to request resources for INT3496:00 (irq 174) on irqchip chv-gpio
[ 2382.484518] intel-int3496 INT3496:00: can't request IRQ for USB ID GPIO: -22
[ 2382.500359] intel-int3496: probe of INT3496:00 failed with error -22

In order to make GPIO ACPI library stricter prepare users of
gpiod_get_index() to correctly behave when there no mapping is
provided by firmware.
Here we add explicit mapping between _CRS GpioIo() resources and
their names used in the driver.

The streaming_maxburst module parameter is 0 offset (0..15)
so we must add 1 while using it for wBytesPerInterval
calculation for the SuperSpeed companion descriptor.
Without this host uvcvideo driver will always see the wrong
wBytesPerInterval for SuperSpeed uvc gadget and may not find
a suitable video interface endpoint.
e.g. for streaming_maxburst = 0 case it will always
fail as wBytePerInterval was evaluating to 0.

On CPU online the cpufreq core restores the previous governor (or
the previous "policy" setting for ->setpolicy drivers), but it does
not restore the min/max limits at the same time, which is confusing,
inconsistent and real pain for users who set the limits and then
suspend/resume the system (using full suspend), in which case the
limits are reset on all CPUs except for the boot one.
Fix this by making cpufreq_online() restore the limits when an inactive
policy is brought online.
The commit log and patch are inspired from Rafael's earlier work.

The VRF driver takes a reference to the inet6_dev on the VRF device for
its rt6_local dst when handling local traffic through the VRF device as
a loopback. When the device is deleted the driver does a put on the idev
but does not reset rt6i_idev in the rt6_info struct. When the dst is
destroyed, dst_destroy calls ip6_dst_destroy which does a second put for
what is essentially the same reference causing it to be prematurely freed.
Reset rt6i_idev after the put in the vrf driver.
