Three conflicts, one of which, for marvell10g.c is non-trivial and
requires some follow-up from Heiner or someone else.
The issue is that Heiner converted the marvell10g driver over to
use the generic c45 code as much as possible.
However, in 'net' a bug fix appeared which makes sure that a new
local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0
is cleared.

A previous change allowed I2C client devices to discover new IRQs upon
reprobe by clearing the IRQ in i2c_device_remove. However, if an IRQ was
assigned in i2c_new_device, that information is lost.
For example, the touchscreen and trackpad devices on a Dell Inspiron laptop
are I2C devices whose IRQs are defined by ACPI extended IRQ types. The
client device structures are initialized during an ACPI walk. After
removing the i2c_hid device, modprobe fails.
This change caches the initial IRQ value in i2c_new_device and then resets
the client device IRQ to the initial value in i2c_device_remove.

This fixes a regression introduced by
commit 0d2e778e38
"net: phy: replace PHY_HAS_INTERRUPT with a check for
config_intr and ack_interrupt".
This assumes that a PHY cannot trigger interrupt unless
it has .config_intr() or .ack_interrupt() implemented.
A later patch makes the code assume both need to be
implemented for interrupts to be present.
But this PHY (which is inside a DSA) will happily
fire interrupts without either callback.
Implement dummy callbacks for .config_intr() and
.ack_interrupt() in the phy header to fix this.
Tested on the RTL8366RB on D-Link DIR-685.

Flow entropy is calculated on the inner packet headers and used for
flow distribution in processing, routing etc. For GRE-type
encapsulations the entropy value is placed in the eight LSB of the key
field in the GRE header as defined in NVGRE RFC 7637. For UDP based
encapsulations the entropy value is placed in the source port of the
UDP header.
The hardware may support entropy calculation specifically for GRE and
for all tunneling protocols. With commit df2ef3bff1 ("net/mlx5e: Add
GRE protocol offloading") GRE is offloaded, but the hardware is
configured by default to calculate flow entropy so packets transmitted
on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN),
GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the
hardware behaviour must be controlled by the driver.
Ensure port entropy calculation is enabled for offloaded VXLAN tunnels
and disable port entropy calculation in the presence of offloaded GRE
tunnels by monitoring the presence of entropy enabling tunnels (i.e
VXLAN) and entropy disabing tunnels (i.e GRE).

When using the device packet encapsulation offload, the device
calculates an entropy value, representing the inner packet headers. The
entropy field is placed inside the outer packet headers. For UDP-type
encapsulations, the entropy is placed in the source port field of the
UDP header. For GRE-type encapsulations, the entropy is placed in the 8
LSB of the key field in the GRE header. If the device does not recognize
the encapsulation type, the entropy is not placed in the packet.
Entropy setting can be controlled using PCMR register. if encapsulation
offload is not used force_entropy_cap should be set to 0x0. Entropy
setting is enabled/disabled using entropy_calc, and could be
additionally enabled/disabled for GRE encapsulation by entropy_gre_calc.
As a pre-step to automatically control the tunnel entropy, introduce
the entropy fields in the PCMR register with no functional change.

If the socket was created with socket(AF_PACKET, SOCK_RAW, 0),
skb->protocol will be unset, __skb_flow_dissect() will fail, and
skb_probe_transport_header() will fall back to the offset_hint, making
the resulting skb_transport_offset incorrect.
If, however, there is no transport header in the packet,
transport_header shouldn't be set to an arbitrary value.
Fix it by leaving the transport offset unset if it couldn't be found, to
be explicit rather than to fill it with some wrong value. It changes the
behavior, but if some code relied on the old behavior, it would be
broken anyway, as the old one is incorrect.

Currently, the address range calculation for file-based filters works as
long as the vma that maps the matching part of the object file starts
from offset zero into the file (vm_pgoff==0). Otherwise, the resulting
filter range would be off by vm_pgoff pages. Another related problem is
that in case of a partially matching vma, that is, a vma that matches
part of a filter region, the filter range size wouldn't be adjusted.
Fix the arithmetics around address filter range calculations, taking
into account vma offset, so that the entire calculation is done before
the filter configuration is passed to the PMU drivers instead of having
those drivers do the final bit of arithmetics.

Align the payload of "user" and "logon" keys so that users of the
keyrings service can access it as a struct that requires more than
2-byte alignment. fscrypt currently does this which results in the read
of fscrypt_key::size being misaligned as it needs 4-byte alignment.
Align to __alignof__(u64) rather than __alignof__(long) since in the
future it's conceivable that people would use structs beginning with
u64, which on some platforms would require more than 'long' alignment.

2018 REVmd of the spec introduces the max channel switch time
element which is optionally included in beacons/probes when there
is a channel switch / extended channel switch element.
The value represents the maximum delay between the time the AP
transmitted the last beacon in current channel and the expected
time of the first beacon in the new channel, in TU.
Parse the value and pass it to the driver.

This extends the NL80211_CMD_ASSOCIATE event case to report
NL80211_ATTR_REQ_IE similarly to what is already done with the
NL80211_CMD_CONNECT events if the driver provides this information. In
practice, this adds (Re)Association Request frame information element
reporting to mac80211 drivers for the cases where user space SME is
used.
This provides more information for user space to figure out which
capabilities were negotiated for the association. For example, this can
be used to determine whether HT, VHT, or HE is used.

On Chrome OS we want to use USBguard to potentially limit access to USB
devices based on policy. We however to do not want to wait for userspace to
come up before initializing fixed USB devices to not regress our boot
times.
This patch adds option to instruct the kernel to only authorize devices
connected to the internal ports. Previously we could either authorize
all or none (or, by default, we'd only authorize wired devices).
The behavior is controlled via usbcore.authorized_default command line
option.

Custom approximation of fractional-divider may not need parent clock
rate checking. For example Rockchip SoCs work fine using grand parent
clock rate even if target rate is greater than parent.
This patch checks parent clock rate only if CLK_SET_RATE_PARENT flag
is set.
For detailed example, clock tree of Rockchip I2S audio hardware.
- Clock rate of CPLL is 1.2GHz, GPLL is 491.52MHz.
- i2s1_div is integer divider can divide N (N is 1~128).
Input clock is CPLL or GPLL. Initial divider value is N = 1.
Ex) PLL = CPLL, N = 10, i2s1_div output rate is
CPLL / 10 = 1.2GHz / 10 = 120MHz
- i2s1_frac is fractional divider can divide input to x/y, x and
y are 16bit integer.
CPLL --> | selector | ---> i2s1_div -+--> | selector | --> I2S1 MCLK
GPLL --> | | ,--------------' | |
`--> i2s1_frac ---> | |
Clock mux system try to choose suitable one from i2s1_div and
i2s1_frac for master clock (MCLK) of I2S1.
Bad scenario as follows:
- Try to set MCLK to 8.192MHz (32kHz audio replay)
Candidate setting is
- i2s1_div: GPLL / 60 = 8.192MHz
i2s1_div candidate is exactly same as target clock rate, so mux
choose this clock source. i2s1_div output rate is changed
491.52MHz -> 8.192MHz
- After that try to set to 11.2896MHz (44.1kHz audio replay)
Candidate settings are
- i2s1_div : CPLL / 107 = 11.214945MHz
- i2s1_frac: i2s1_div = 8.192MHz
This is because clk_fd_round_rate() thinks target rate
(11.2896MHz) is higher than parent rate (i2s1_div = 8.192MHz)
and returns parent clock rate.
Above is current upstreamed behavior. Clock mux system choose
i2s1_div, but this clock rate is not acceptable for I2S driver, so
users cannot replay audio.
Expected behavior is:
- Try to set master clock to 11.2896MHz (44.1kHz audio replay)
Candidate settings are
- i2s1_div : CPLL / 107 = 11.214945MHz
- i2s1_frac: i2s1_div * 147/6400 = 11.2896MHz
Change i2s1_div to GPLL / 1 = 491.52MHz at same
time.
If apply this commit, clk_fd_round_rate() calls custom approximate
function of Rockchip even if target rate is higher than parent.
Custom function changes both grand parent (i2s1_div) and parent
(i2s_frac) settings at same time. Clock mux system can choose
i2s1_frac and audio works fine.

clang warns about overflowing the data[] member in the struct pnpipehdr:
net/phonet/pep.c:295:8: warning: array index 4 is past the end of the array (which contains 1 element) [-Warray-bounds]
if (hdr->data[4] == PEP_IND_READY)
^ ~
include/net/phonet/pep.h:66:3: note: array 'data' declared here
u8 data[1];
Using a flexible array member at the end of the struct avoids the
warning, but since we cannot have a flexible array member inside
of the union, each index now has to be moved back by one, which
makes it a little uglier.
