On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2020-06-11
This series contains fixes to the iavf driver.
Brett fixes the supported link speeds in the iavf driver, which was only
able to report speeds that the i40e driver supported and was missing the
speeds supported by the ice driver. In addition, fix how 2.5 and 5.0
GbE speeds are reported.
Alek fixes a enum comparison that was comparing two different enums that
may have different values, so update the comparison to use matching
enums.
Paul increases the time to complete a reset to allow for 128 VFs to
complete a reset.

Current below problems exists.
1. devlink device is registered by mlx5_load_one(). But it is
not unregistered by mlx5_unload_one(). This is incorrect.
2. Above issue leads to,
When mlx5 PCI device is removed, currently devlink device is
unregistered before devlink ports are unregistered in below ladder
diagram.
remove_one()
mlx5_devlink_unregister()
[..]
devlink_unregister() <- ports are still registered!
mlx5_unload_one()
mlx5_unregister_device()
mlx5_remove_device()
mlx5e_remove()
mlx5e_devlink_port_unregister()
devlink_port_unregister()
3. Condition checking for registering and unregister device are not
symmetric either in these routines.
Hence, fix the sequence by having load and unload routines symmetric
and in right order.
i.e.
(a) register devlink device followed by registering devlink ports
(b) unregister devlink ports followed by devlink device
Do this based on boot and cleanup flags instead of different
conditions.

After an XSK is closed, the relevant structures in the channel are not
zeroed. If an XSK is opened the second time on the same channel without
recreating channels, the stray values in the structures will lead to
incorrect operation of queues, which causes CQE errors, and the new
socket doesn't work at all.
This patch fixes the issue by explicitly zeroing XSK-related structs in
the channel on XSK close. Note that those structs are zeroed on channel
creation, and usually a configuration change (XDP program is set)
happens on XSK open, which leads to recreating channels, so typical XSK
usecases don't suffer from this issue. However, if XSKs are opened and
closed on the same channel without removing the XDP program, this bug
reproduces.

Currently, in case of fatal error during mlx5_load_one(), we cannot
enter error state until mlx5_load_one() is finished, what can take
several minutes until commands will get timeouts, because these commands
can't be processed due to the fatal error.
Fix it by setting dev->state as MLX5_DEVICE_STATE_INTERNAL_ERROR before
requesting the lock.

Link speeds are communicated over virtchnl using an enum
virtchnl_link_speed. Currently, the highest link speed is 40Gbps which
leaves us unable to reflect some speeds that an ice VF is capable of.
This causes link speed to be misreported on the iavf driver.
Allow for communicating link speeds using Mbps so that the proper speed can
be reported for an ice VF. Moving away from the enum allows us to
communicate future speed changes without requiring a new enum to be added.
In order to support communicating link speeds over virtchnl in Mbps the
following functionality was added:
- Added u32 link_speed_mbps in the iavf_adapter structure.
- Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF
driver supports communicating link speeds in Mbps.
- Added the function iavf_get_vpe_link_status() to fill the
correct link_status in the event_data union based on the
ADV_LINK_SUPPORT(_a) macro.
- Added the function iavf_set_adapter_link_speed_from_vpe()
to determine whether or not to fill the u32 link_speed_mbps or
enum virtchnl_link_speed link_speed field in the iavf_adapter
structure based on the ADV_LINK_SUPPORT(_a) macro.
- Do not free vf_res in iavf_init_get_resources() as vf_res will be
accessed in iavf_get_link_ksettings(); memset to 0 instead. This
memory is subsequently freed in iavf_remove().

The netif_running() test looks at __LINK_STATE_START which
gets set before ndo_open() is called, there is a window of
time between that and when the queues are actually ready to
be run. If ionic_check_link_status() notices that the link is
up very soon after netif_running() becomes true, it might try
to run the queues before they are ready, causing all manner of
potential issues. Since the netdev->flags IFF_UP isn't set
until after ndo_open() returns, we can wait for that before
we allow ionic_check_link_status() to start the queues.
On the way back to close, __LINK_STATE_START is cleared before
calling ndo_stop(), and IFF_UP is cleared after. Both of
these need to be true in order to safely stop the queues
from ionic_check_link_status().

Patch series "mm: consolidate definitions of page table accessors", v2.
The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once. For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.
Most of these definitions are actually identical and typically it boils
down to, e.g.
static inline unsigned long pmd_index(unsigned long address)
{
return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}
static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}
These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.
For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.
These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.
This patch (of 12):
The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g. pte_alloc() and
pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.
The include statements in such cases are remove with a simple loop:
for f in $(git grep -l "include <linux/mm.h>") ; do
sed -i -e '/include <asm\/pgtable.h>/ d' $f
done

The driver registers three different types of thermal zones: For the
ASIC itself, for port modules and for gearboxes.
Currently, all three types use the same get_trend() callback which does
not work correctly for the ASIC thermal zone. The callback assumes that
the device data is of type 'struct mlxsw_thermal_module', whereas for
the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data.
Fix this by using one get_trend() callback for the ASIC thermal zone and
another for the other two types.

Pull rdma updates from Jason Gunthorpe:
"A more active cycle than most of the recent past, with a few large,
long discussed works this time.
The RNBD block driver has been posted for nearly two years now, and
flowing through RDMA due to it also introducing a new ULP.
The removal of FMR has been a recurring discussion theme for a long
time.
And the usual smattering of features and bug fixes.
Summary:
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and
a mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block
RDMA device specific to ionos's cloud environment. It brings strong
multipath and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple
async fds

This fixes a crash introduced by recent is_kdump_kernel() check.
The source of the crash is that kdump kernel can be loaded on a
system with already created VFs. But for such VFs, it will follow
a logic path of PF and eventually crash.
Thus, we are partially reverting back previous changes and instead
use is_kdump_kernel is a single init point of PF init, where we
disable SRIOV explicitly.

Commit ca23cb0bc50f ("mvneta: MVNETA_SKB_HEADROOM set last 3 bits to zero")
added headroom alignment check against 8.
Hovewer (if we imagine that NET_SKB_PAD or XDP_PACKET_HEADROOM is not
aligned to cacheline size), it actually aligns headroom down, while
skb/xdp_buff headroom should be *at least* equal to one of the values
(depending on XDP prog presence).
So, fix the check to align the value up. This satisfies both
hardware/driver and network stack requirements.

Th referenced change added an extra hw reset to rtl8169_net_suspend()
what makes WoL fail on few chip versions. Therefore skip the extra
reset if we're going down and WoL is enabled.
In rtl_shutdown() rtl8169_hw_reset() is called by rtl8169_net_suspend()
already if needed, therefore avoid issues issue by removing the extra
call. The fix was tested on a system with RTL8168g.
Meanwhile rtl8169_hw_reset() does more than a hw reset and should be
renamed. But that's net-next material.

This patch fixes two issues with XDP:
1. If the XDP verdict is XDP_ABORTED we break the loop, which results in
us handling one buffer per napi cycle instead of the total budget
(usually 64). To overcome this simply change the xdp_verdict check to
!= XDP_PASS. When the verdict is XDP_PASS, the skb is not expected to
be NULL.
2. Update the residual budget for XDP_DROP and XDP_ABORTED, since
packets are handled in these cases.

Pull power management updates from Rafael Wysocki:
"These rework the system-wide PM driver flags, make runtime switching
of cpuidle governors easier, improve the user space hibernation
interface code, add intel-speed-select interface documentation, add
more debug messages to the ACPI code handling suspend to idle, update
the cpufreq core and drivers, fix a minor issue in the cpuidle core
and update two cpuidle drivers, improve the PM-runtime framework,
update the Intel RAPL power capping driver, update devfreq core and

- Document the intel-speed-select sysfs interface (Srinivas
Pandruvada).
- Make the ACPI code handing suspend to idle print more debug
messages to help diagnose issues with it (Rafael Wysocki).
- Fix a helper routine in the cpufreq core and correct a typo in the
struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
Wenhu).
- Update cpufreq drivers:
- Make the intel_pstate driver start in the passive mode by
default on systems without HWP (Rafael Wysocki).
- Add i.MX7ULP support to the imx-cpufreq-dt driver and add
i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
- Convert the qoriq cpufreq driver to a platform one, make the
platform code create a suitable device object for it and add
platform dependencies to it (Mian Yousaf Kaukab, Geert
Uytterhoeven).
- Fix wrong compatible binding in the qcom driver (Ansuel Smith).
- Build the omap driver by default for ARCH_OMAP2PLUS (Anders
Roxell).

cpuidle core (Qiushi Wu).
- Convert Qualcomm SPM to a generic cpuidle driver (Stephan
Gerhold).
- Fix up the execution order when entering a domain idle state in
the PSCI driver (Ulf Hansson).
- Fix a reference counting issue related to clock management and
clean up two oddities in the PM-runtime framework (Rafael Wysocki,
Andy Shevchenko).
- Add ElkhartLake support to the Intel RAPL power capping driver and
remove an unused local MSR definition from it (Jacob Pan, Sumeet
Pawnikar).
- Update devfreq core and drivers:
- Replace strncpy() with strscpy() in the devfreq core and use
lockdep asserts instead of manual checks for a locked mutex in
it (Dmitry Osipenko, Krzysztof Kozlowski).
- Add a generic imx bus scaling driver and make it register an
interconnect device (Leonard Crestez, Gustavo A. R. Silva).
- Make the cpufreq notifier in the tegra30 driver take boosting
into account and delete an unuseful error message from that
driver (Dmitry Osipenko, Markus Elfring).
- Remove unneeded semicolon from the cpupower code (Zou Wei)"
