When there is a CM id object that has port assigned to it, it means that
the cm-id asked for the specific port that it should go by it, but if
that port was removed (hot-unplug event) the cm-id was not updated.
In order to fix that the port keeps a list of all the cm-id's that are
planning to go by it, whenever the port is removed it marks all of them
as invalid.

Commit 7619751f8c90 ("ARM: 8595/2: apply more __ro_after_init") caused
a regression with XIP kernels by moving the __ro_after_init data into
the read-only section. With XIP kernels, the read-only section is
located in read-only memory from the very beginning.
Work around this by moving the __ro_after_init data back into the .data
section, which will be in RAM, and hence will be writable.
It should be noted that in doing so, this remains writable after init.

With RGMII, we need a 1.5 to 2ns skew between clock and data lines. The
VSC8601 can handle this internally. While the VSC8601 can set more
fine-grained delays, the standard skew settings work out of the box.
The same heuristic is used to determine when this skew should be enabled
as in vsc824x_config_init().
Tested on custom board with AM3352 SOC and VSC801 PHY.

This option was added in 6a89a314ab107a12af08c71420c19a37a30fc2d3 to
allow use of the devm_gpio_* functions without CONFIG_GPIOLIB.
However, only a few months later in
b69ac52449c658b7ac40034dc3c5f5f4a71a723d, CONFIG_GPIOLIB was added
as a dependency, defeating the original purpose of this option.
Instead of that patch, the original commit could have just been
reverted (and in fact was partially so in
403c1d0be5ccbd750d25c59d8358843a81e52e3b). Further, since this
option has a dependency on HAS_IOMEM, even though it does not
require it, it causes build failures when !HAS_IOMEM (e.g. in a
uml build).
Fix that by completely removing the option, in essence completing
the reversion of the original commit.

This patch fixes the following
1. When interface is being teardown and queues are being cleaned up,
free pending SKBs that are in SQ which are either not transmitted
or freed as NAPI is disabled by that time.
2. While interface initialization, delay CFG_DONE notification till
the end to avoid corner cases where TXQs are enabled but CQ
interrupts are not which results blocking transmission and kicking
off watchdog.
3. Check for IFF_UP while re-enabling RBDR interrupts from tasklet.

This patch fixes multiple issues
1. Convert all driver statistics to percpu counters for accuracy.
2. To avoid multiple CQEs posted by a TSO packet appended to HW,
TSO pkt's SQE has 'post_cqe' not set but a dummy SQE is added
for getting HW transmit completion notification. This dummy
SQE has 'dont_send' set and HW drops the pkt pointed to in this
thus Tx drop counter increases. This patch fixes this by subtracting
SW tx tso counter from HW Tx drop counter for actual packet drop counter.
3. Reset all individual queue's and VNIC HW stats when interface is going down.
4. Getrid off unnecessary counters in hot path.
5. Bringout all CQE error stats i.e both Rx and Tx.

Programming LMAC credits taking 9K frame size by default is incorrect
as for an interface which is one of the many on the same BGX/QLM
no of credits available will be less as Tx FIFO will be divided
across all interfaces. So let's say a BGX with 40G interface and another
BGX with multiple 10G, bandwidth of 10G interfaces will be effected when
traffic is running on both 40G and 10G interfaces simultaneously.
This patch fixes this issue by programming credits based on netdev's MTU.
Also fixed configuring MTU to HW and added CQE counter for pkts which

ipv4: Fix memory leaks and reference issues in fib
This series fixes one major issue and one minor issue in the fib tables.
The major issue is that we had lost the functionality that was flushing the
local table entries from main after we had unmerged the two tries. In
order to regain the functionality I have performed a partial revert and
then moved the functionality for flushing the external entries from main
into fib_unmerge.
The minor issue was a memory leak that could occur in the event that we
weren't able to add an alias to the local trie resulting in the fib alias
being leaked.

The patch that removed the FIB offload infrastructure was a bit too
aggressive and also removed code needed to clean up us splitting the table
if additional rules were added. Specifically the function
fib_trie_flush_external was called at the end of a new rule being added to
flush the foreign trie entries from the main trie.
I updated the code so that we only call fib_trie_flush_external on the main
table so that we flush the entries for local from main. This way we don't
call it for every rule change which is what was happening previously.

I made some invalid assumptions with BPF_AND and BPF_MOD that could result in
invalid accesses to bpf map entries. Fix this up by doing a few things
1) Kill BPF_MOD support. This doesn't actually get used by the compiler in real
life and just adds extra complexity.
2) Fix the logic for BPF_AND, don't allow AND of negative numbers and set the
minimum value to 0 for positive AND's.
3) Don't do operations on the ranges if they are set to the limits, as they are
by definition undefined, and allowing arithmetic operations on those values
could make them appear valid when they really aren't.
This fixes the testcase provided by Jann as well as a few other theoretical
problems.

Since commit c4dd1ba355aae2bc3d1213da6c66c53e3c31e028
("mfd: stmpe: Add reset support for all STMPE variant")
we're resetting the STMPE expanders before use.
This caused a regression on the STMP2401 on the Nomadik
NHK8815:
stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101
nmk-i2c 101f8000.i2c0: write to slave 0x43 timed out
nmk-i2c 101f8000.i2c0: no ack received after address transmission
stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101
nmk-i2c 101f8000.i2c0: write to slave 0x44 timed out
nmk-i2c 101f8000.i2c0: no ack received after address transmission
It turns out that we start to poll for the reset bit to
go low again too quickly: the STMPE2401 is not yet online and
ready to be asked for the status of the RESET bit.
By introducing a 10ms delay before starting to hammer
the register for information, we get back to normal:
stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101
stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101

states when no_console_suspend flag is enabled. The system
and serial console both hang. The resetting of device is not
needed while going to suspend. Hence remove this code.

There are a few issues on Intel Kaby Lake PCH-H properties added by
commit a6a576b78e09 ("mfd: lpss: Add Intel Kaby Lake PCH-H PCI IDs"):
- Input clock of I2C controller on Intel Kaby Lake PCH-H is 120 MHz not
133 MHz. This was probably copy-paste error from Intel Broxton I2C
properties.
- There is no default I2C SDA hold time specified which is used when
ACPI doesn't provide it. I got information from Windows driver team
that Kaby Lake PCH-H can use the same configuration than Intel
Sunrisepoint PCH.
- Common HS-UART properties are not used.
Fix these by reusing the Sunrisepoint properties on Kaby Lake PCH-H.

client uncore IMC
Vince Weaver reported the following bug when KASAN is enabled:
[ 205.748005] BUG: KASAN: slab-out-of-bounds in snb_uncore_imc_event_del+0x6c/0xa0 at addr ffff8800caa43768
[ 205.758324] Read of size 8 by task perf_fuzzer/6618
It's caused by accessing box->event_list.
For client IMC, there are no generic counters. It defines its own fixed
free running counters. So event_list and n_events are unused.
They can be removed safely, which fixes the bug.
( There's still the separate question of how uninitialized state snuck into
this data structure - but that's a separate fix. )

The screen_info.lfb_size field is shifted by 16 bits *only* in case of
VBE. This has historical reasons since VBE advertised it similarly.
However, in case of EFI framebuffers, the size is no longer shifted. Fix
the x86 simple-framebuffer setup code to use the correct size in the
non-VBE case.
While at it, avoid variable abbreviations and rename 'len' to 'length',
and use the correct types matching the screen_info definition.

The screen_info object was extended to support 64-bit lfb_base addresses
in:
ae2ee627dc87 ("efifb: Add support for 64-bit frame buffer addresses")
However, the x86 simple-framebuffer setup code never made use of it. Fix
it to properly assemble and verify the lfb_base before advertising
simple-framebuffer devices.
In particular, this means if VIDEO_CAPABILITY_64BIT_BASE is set, the
screen_info->ext_lfb_base field will contain the upper 32bit of the
actual lfb_base. Make sure the address is not 0 (i.e., unset), as well as
does not overflow the physical address type.

specified in the VBT
My heuristic for detecting type 1 DVI DP++ adaptors based on the VBT
port information apparently didn't survive the reality of buggy VBTs.
In this particular case we have a machine with a natice HDMI port, but
the VBT tells us it's a DP++ port based on its capabilities.
The dvo_port information in VBT does claim that we're dealing with a
HDMI port though, but we have other machines which do the same even
when they actually have DP++ ports. So that piece of information alone
isn't sufficient to tell the two apart.
After staring at a bunch of VBTs from various machines, I have to
conclude that the only other semi-reliable clue we can use is the
presence of the AUX channel in the VBT. On this particular machine
AUX channel is specified as zero, whereas on some of the other machines
which listed the DP++ port as HDMI have a non-zero AUX channel.
I've also seen VBTs which have dvo_port a DP but have a zero AUX
channel. I believe those we need to treat as DP ports, so we'll limit
the AUX channel check to just the cases where dvo_port is HDMI.
If we encounter any more serious failures with this heuristic I think
we'll have to have to throw it out entirely. But that could mean that
there is a risk of type 1 DVI dongle users getting greeted by a
black screen, so I'd rather not go there unless absolutely necessary.

The size reported by rtnl_vfinfo_size doesn't match the space used by
rtnl_fill_vfinfo.
rtnl_vfinfo_size currently doesn't account for the nest attributes
used by statistics (added in commit 3b766cd83232), nor for struct
ifla_vf_tx_rate (since commit ed616689a3d9, which added ifla_vf_rate
to the dump without removing ifla_vf_tx_rate, but replaced
ifla_vf_tx_rate with ifla_vf_rate in the size computation).

Rolf Neugebauer reported very long delays at netns dismantle.
Eric W. Biederman was kind enough to look at this problem
and noticed synchronize_net() occurring from netif_napi_del() that was
added in linux-4.5
Busy polling makes no sense for tunnels NAPI.
If busy poll is used for sessions over tunnels, the poller will need to
poll the physical device queue anyway.
netif_tx_napi_add() could be used here, but function name is misleading,
and renaming it is not stable material, so set NAPI_STATE_NO_BUSY_POLL
bit directly.
This will avoid inserting gro_cells napi structures in napi_hash[]
and avoid the problematic synchronize_net() (per possible cpu) that
Rolf reported.

It can be enabled explicity using 'ifconfig eth0 multicast'.

stmmac: fix PTP support
This subset of patches aim to fix the PTP support
for the stmmac and especially for 4.x chip series.
While setting PTP on an ST box with 4.00a Ethernet
core, the kernel panics due to a broken settings
of the descriptors. The patches review the
register configuration, the algo used for configuring
the protocol, the way to get the timestamp inside
the RX/TX descriptors and, in the end, the statistics
displayed by ethtool.
V2: RESEND all the patches adding the Acked-by.
