Pull parisc fixes from Helge Deller:
- Fix crashes when accessing PCI devices on some machines like C240 and
J5000. The crashes were triggered because we replaced cache flushes
by nops in the alternative coding where we shouldn't for some

- Dave fixed a race in the usage of the sr1 space register when used to
load the coherence index.
- Use the hardware lpa instruction to to load the physical address of
kernel virtual addresses in the iommu driver code.
- The kernel may fail to link when CONFIG_MLONGCALLS isn't set. Solve
that by rearranging functions in the final vmlinux executeable.

Most I/O in the kernel is done using the kernel offset mapping.
However, there is one API that uses aliased kernel address ranges:
> The final category of APIs is for I/O to deliberately aliased address
> ranges inside the kernel. Such aliases are set up by use of the
> vmap/vmalloc API. Since kernel I/O goes via physical pages, the I/O
> subsystem assumes that the user mapping and kernel offset mapping are
> the only aliases. This isn't true for vmap aliases, so anything in
> the kernel trying to do I/O to vmap areas must manually manage
> coherency. It must do this by flushing the vmap range before doing
> I/O and invalidating it after the I/O returns.
For this reason, we should use the hardware lpa instruction to load the
physical address of kernel virtual addresses in the driver code.
I believe we only use the vmap/vmalloc API with old PA 1.x processors
which don't have a sba, so we don't hit this problem.

We only support I/O to kernel space. Using %sr1 to load the coherence
index may be racy unless interrupts are disabled. This patch changes the
code used to load the coherence index to use implicit space register
selection. This saves one instruction and eliminates the race.

WoL magic packet configuration sometimes does not work due to
couple of leakages found.
Mainly there was a regression introduced during readx_poll refactoring.
Next, fw request waiting time was too small. Sometimes that
caused sleep proxy config function to return with an error
and to skip WoL configuration.
At last, WoL data were passed to FW from not clean buffer.
That could cause FW to accept garbage as a random configuration data.

Enabling sysfs attribute bridge_hostnotify triggers a series of udev events
for the MAC addresses of all currently connected peers. In case no VLAN is
set for a peer, the device reports the corresponding MAC addresses with
VLAN ID 4096. This currently results in attribute VLAN=4096 for all
non-VLAN interfaces in the initial series of events after host-notify is
enabled.
Instead, no VLAN attribute should be reported in the udev event for
non-VLAN interfaces.
Only the initial events face this issue. For dynamic changes that are
reported later, the device uses a validity flag.
This also changes the code so that it now sets the VLAN attribute for
MAC addresses with VID 0. On Linux, no qeth interface will ever be
registered with VID 0: Linux kernel registers VID 0 on all network
interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0.
Peers with other OSs could register MACs with VID 0.

While qeth_l3 uses netif_keep_dst() to hold onto the dst, a skb's dst
may still have been obsoleted (via dst_dev_put()) by the time that we
end up using it. The dst then points to the loopback interface, which
means the neighbour lookup in qeth_l3_get_cast_type() determines a bogus
cast type of RTN_BROADCAST.
For IQD interfaces this causes us to place such skbs on the wrong
HW queue, resulting in TX errors.
Fix-up the various call sites to first validate the dst entry with
dst_check(), and fall back accordingly.

When selecting the cast type of a neighbourless IPv4 skb (eg. on a raw
socket), qeth_l3 falls back to the packet's destination IP address.
For this case we should classify traffic sent to 255.255.255.255 as
broadcast.
This fixes DHCP requests, which were misclassified as unicast
(and for IQD interfaces thus ended up on the wrong HW queue).

There's some NICs, such as hinic, with NETIF_F_IP_CSUM and NETIF_F_TSO
on but NETIF_F_HW_CSUM off. And ipvlan device features will be
NETIF_F_TSO on with NETIF_F_IP_CSUM and NETIF_F_IP_CSUM both off as
IPVLAN_FEATURES only care about NETIF_F_HW_CSUM. So TSO will be

The hardware values for link speed are held in the sja1105_speed_t enum.
However they do not increase in the order that sja1105_get_speed_cfg was
iterating over them (basically from SJA1105_SPEED_AUTO - 0 - to
SJA1105_SPEED_1000MBPS - 1 - skipping the other two).
Another bug is that the code in sja1105_adjust_port_config relies on the
fact that an invalid link speed is detected by sja1105_get_speed_cfg and
returned as -EINVAL. However storing this into an enum that only has
positive members will cast it into an unsigned value, and it will miss
the negative check.
So take the simplest approach and remove the sja1105_get_speed_cfg
function and replace it with a simple switch-case statement.

Some SFP modules do not like reads longer than 16 bytes, so read the
EEPROM in chunks of 16 bytes at a time. This behaviour is not specified
in the SFP MSAs, which specifies:
"The serial interface uses the 2-wire serial CMOS E2PROM protocol
defined for the ATMEL AT24C01A/02/04 family of components."
and
"As long as the SFP+ receives an acknowledge, it shall serially clock
out sequential data words. The sequence is terminated when the host
responds with a NACK and a STOP instead of an acknowledge."
We must avoid breaking a read across a 16-bit quantity in the diagnostic
page, thankfully all 16-bit quantities in that page are naturally
aligned.

When non-bridged, non-vlan'ed mv88e6xxx port is moving down, error
message is logged:
failed to kill vid 0081/0 for device eth_cu_1000_4
This is caused by call from __vlan_vid_del() with vin set to zero, over
call chain this results into _mv88e6xxx_port_vlan_del() called with
vid=0, and mv88e6xxx_vtu_get() called from there returns -EINVAL.
On symmetric path moving port up, call goes through
mv88e6xxx_port_vlan_prepare() that calls mv88e6xxx_port_check_hw_vlan()
that returns -EOPNOTSUPP for zero vid.
This patch changes mv88e6xxx_vtu_get() to also return -EOPNOTSUPP for
zero vid, then this error code is explicitly cleared in
dsa_slave_vlan_rx_kill_vid() and error message is no longer logged.

The second patch fixes up a number of places in the tree where people

not even type their own name all the time without mistakes, this was
bound to happen, and odds are, we will have to add some type of check

Prior to the adoption of SPDX, it was difficult for tools to determine
the correct license due to incomplete or badly formatted license text.
The SPDX solves this issue, assuming people can correctly spell
"SPDX-License-Identifier" although this assumption is broken in some
places.
Since scripts/spdxcheck.py parses only lines that exactly matches to
the correct tag, it cannot (should not) detect this kind of error.
If the correct tag is missing, scripts/checkpatch.pl warns like this:
WARNING: Missing or malformed SPDX-License-Identifier tag in line *
So, people should notice it before the patch submission, but in reality
broken tags sometimes slip in. The checkpatch warning is not useful for
checking the committed files globally since large number of files still
have no SPDX tag.
Also, I am not sure about the legal effect when the SPDX tag is broken.
Anyway, these typos are absolutely worth fixing. It is pretty easy to
find suspicious lines by grep.

Pull power management fixes from Rafael Wysocki:
"These fix three issues in the system-wide suspend and hibernation area
related to PCI device PM handling by suspend-to-idle, device wakeup
optimizations and arbitrary differences between suspend and
hiberantion.
Specifics:
- Modify the PCI bus type's PM code to avoid putting devices left by
their drivers in D0 on purpose during suspend to idle into
low-power states as doing that may confuse the system resume
callbacks of the drivers in question (Rafael Wysocki).
- Avoid checking ACPI wakeup configuration during system-wide suspend
for suspended devices that do not use ACPI-based wakeup to allow
them to stay in suspend more often (Rafael Wysocki).
- The last phase of hibernation is analogous to system-wide suspend
also because on platforms with ACPI it passes control to the
platform firmware to complete the transision, so make it indicate
that by calling pm_set_suspend_via_firmware() to allow the drivers
that care about this to do the right thing (Rafael Wysocki)"

Pull yet more SPDX updates from Greg KH:
"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers"

drm/imx: ipuv3-plane: fix frame rate regression on non-plus i.MX6Q
Fix a regression introduced by 70e8a0c71e9 ("drm/imx: ipuv3-plane: add
function to query atomic update status") that halves the frame rate on
non-plus i.MX6Q, because the pending check always returns "pending"
even if an update is actually applied.

MVPP2_TXQ_SCHED_TOKEN_CNTR_REG() expects the logical queue id but
the current code is passing the global tx queue offset, so it ends
up writing to unknown registers (between 0x8280 and 0x82fc, which
seemed to be unused by the hardware). This fixes the issue by using
the logical queue id instead.

When identical rules are inserted, the latter one goes to C-TCAM. For
that, a second eRP with the same mask is created. These 2 eRPs by the
nature cannot be merged and also one cannot be parent of another.
Teach mlxsw_sp_acl_erp_delta_fill() about this possibility and handle it
gracefully.

(At least) RTL8168e forgets its MAC address in PCI D3. To fix this set
the MAC address when resuming. For resuming from runtime-suspend we
had this in place already, for resuming from S3/S5 it was missing.
The commit referenced as being fixed isn't wrong, it's just the first
one where the patch applies cleanly.
