In order to have different RX handler per profile, fix and refactor the
current code to take the rx handler directly from the netdevice profile
rather than computing it on runtime as it was done with the switchdev
mode representor rx handler.
This will also remove the current wrong assumption in mlx5e_alloc_rq
code that mlx5e_priv->ppriv is of the type vport_rep.

Implement mlx5e's IPoIB SKB transmit using the helper functions provided
by mlx5e ethernet tx flow, the only difference in the code between
mlx5e_xmit and mlx5i_xmit is that IPoIB has some extra fields to fill
(UD datagram segment) in the TX descriptor (WQE) and it doesn't need to
have any vlan handling.

Create IPoIB underlay QP needed by the IPoIB netdevice profile for RSS

Reset the underlay QP on dev_uninit ndo to stop IPoIB traffic going

Like the mlx5e ethernet mode, on IPoIB mode we need to create RX steering
tables, but IPoIB do not require MAC and VLAN steering tables so the
only tables we create in here are:
1. TTC Table (Traffic Type Classifier table for RSS steering)
2. ARFS Table (for accelerated RFS support)
Creation of those tables is identical to mlx5e ethernet mode, hence the
use of mlx5e_create_ttc_table and mlx5e_arfs_create_tables.

Implement IPoIB RX RSS (RQTs and TIRs) HW objects creation,
All we do here is simply reuse the mlx5e implementation to create
direct and indirect (RSS) steering HW objects.
For that we just expose
mlx5e_{create,destroy}_{direct,indirect}_{rqt,tir} functions into en.h
and call them from ipoib.c in init/cleanup_rx IPoIB netdevice profile
callbacks.

In preparation for mlx5e RDMA net_device support, here we generalize
mlx5e_attach/detach in a way that those functions will be agnostic
to link type. For that we move ethernet specific NIC net device logic out
of those functions into {nic,rep}_{enable/disable} mlx5e NIC and
representor profiles callbacks.
Also some of the logic was moved only to NIC profile since it is not right
to have this logic for representor net device (e.g. set port MTU).

The copy_page is optimized memcpy for page-alinged address. If it is
used with non-page aligned address, it can corrupt memory which means
system corruption. With zram, it can happen with
1. 64K architecture
2. partial IO
3. slub debug
Partial IO need to allocate a page and zram allocates it via kmalloc.
With slub debug, kmalloc(PAGE_SIZE) doesn't return page-size aligned
address. And finally, copy_page(mem, cmem) corrupts memory.
So, this patch changes it to memcpy.
Actuaully, we don't need to change zram_bvec_write part because zsmalloc
returns page-aligned address in case of PAGE_SIZE class but it's not
good to rely on the internal of zsmalloc.
Note:
When this patch is merged to stable, clear_page should be fixed, too.
Unfortunately, recent zram removes it by "same page merge" feature so
it's hard to backport this patch to -stable tree.
I will handle it when I receive the mail from stable tree maintainer to
merge this patch to backport.

Field FL/TPL in register TDES3 is not correctly set on GMAC4.
TX appears to be functional on GMAC 4.10a even if this field is not set,
however, to avoid relying on undefined behavior, set the length in TDES3.
The field has a different meaning depending on if the TSE bit in TDES3
is set or not (TSO). However, regardless of the TSE bit, the field is
not optional. The field is already set correctly when the TSE bit is set.
Since there is no limit for the number of descriptors that can be
used for a single packet, the field should be set to the sum of
the buffers contained in:
[<desc with First Descriptor bit set> ... <desc n> ...
<desc with Last Descriptor bit set>], which should be equal to skb->len.

implementation is different, since it requires DTR to be set for
answering to qmi messages.
This patch replaces QMI_FIXED_INTF with QMI_QUIRK_SET_DTR: tests on
LE920 have been performed in order to verify backward compatibility.

Revert commit 57707a9a7780 (ACPICA: Resources: Not a valid resource if
buffer length too long) as it is reported to prevent the TPM module
from loading on Lenovo X60 with Coreboot.
It also causes new confusing warnings to show up in the kernel log.

Pull pin control fixes from Linus Walleij:
"Two pin control fixes arriving late, these are hopefully the last pin
control fixes I send this kernel cycle. A Chromebook and an Exynos SoC
thingie.
The Exynos patch is pretty big, it is fixing unbroken a breakage
caused by yours truly when trying to figure out the merge mess with
the different Samsung platforms for this merge window. Sorry about
that. We have countered this situation by assigning a Samsung pin
control submaintainer to catch stuff earlier.
Summary:
- Make the Acer Chromebook keyboard work again with the Intel
Cherryview driver.
- Fix a merge error in the Exynos 5433 driver"

Disable the MDIO interrupt, falling back to polled mode, if the resource
size does not allow us to access the interrupt registers. All current
DT bindings use a size of 0x84, which allows access, but verifying it is
good practice.

The pre-existing write to disable interrupts on the remove path happens
whether we have an interrupt or not. While this may seem to be a good
idea, this driver is re-used in many different implementations, some
where the binding only specifies four bytes of register space. This
access causes us to access registers outside of the binding.
Make it conditional on the interrupt being present, which is the same
condition used when enabling the interrupt in the first place.

When the mvmdio driver has an interrupt, it enables the "done" interrupt
after requesting its interrupt handler. However, probe failure results
in the interrupt being left enabled. Disable it on the failure path.

Pull drm fixes from Dave Airlie:
"i915, gvt, nouveau, udl and etnaviv fixes.
I was away the end of last week, so some of these would have been in
rc6, and it's Easter from tomorrow, so I decided I better dequeue what
I have now.
The nouveau changes, just add a hw enable for GP107 display (like a
pci id addition really), and fix a couple of regressions. i915 has
some more gvt fixes, along with a few run of the mill ones, the rcu
one seems like a few people have hit it.
Otherwise a small udl and small etnaviv fix"

Commit 10c7e20b2ff3 (ACPI / scan: fix enumeration (visited) flags for
bus rescans) attempted to fix a problem with ACPI-based enumerateion
of I2C/SPI devices, but it forgot to ensure that the visited flag
will be set for all of the other enumerated devices, so fix that.

There is a report that after commit 27622b061eb4 ("cpufreq: Convert
to hotplug state machine"), the normal CPU offline/online cycle
fails on some platforms.
According to the ftrace result, this problem was triggered on
platforms using acpi-cpufreq as the default cpufreq driver,
and due to the lack of some ACPI freq method (eg. _PCT),
cpufreq_online() failed and returned a negative value, so the CPU
hotplug state machine rolled back the CPU online process. Actually,
from the user's perspective, the failure of cpufreq_online() should
not prevent that CPU from being brought up, although cpufreq might
not work on that CPU.
BTW, during system startup cpufreq_online() is not invoked via CPU
online but by the cpufreq device creation process, so the APs can be
brought up even though cpufreq_online() fails in that stage.
This patch ignores the return value of cpufreq_online/offline() and
lets the cpufreq framework deal with the failure. cpufreq_online()
itself will do a proper rollback in that case and if _PCT is missing,
the ACPI cpufreq driver will print a warning if the corresponding
debug options have been enabled.
