550cd7c1b4 bnxt: Read VPD with pci_vpd_alloc()
Use pci_vpd_alloc() to dynamically allocate a properly sized buffer and
read the full VPD data into it.

This simplifies the code, and we no longer have to make assumptions about
VPD size.

35e7f1be79 bnx2: Replace open-coded byte swapping with swab32s()
Read NVRAM directly into buffer and use swab32s() to byte swap it in-place

2d57dd6673 sfc: falcon: Search VPD with pci_vpd_find_ro_info_keyword()
Use pci_vpd_find_ro_info_keyword() to search for keywords in VPD to

Replace netif_err() with pci_err() because the netdevice isn't registered

Use kmemdup_nul() instead of open-coding it.

This is the same as 37838aa437 ("sfc: Search VPD with

6e207b8821 ARM: SoC changes for 5.14
A few SoC (code) changes have queued up this cycle, mostly for minor
 changes and some refactoring and cleanup of legacy platforms. This
 branch also contains a few of the fixes that weren't sent in by the end
 of the release (all fairly minor).
 
  - Adding an additional maintainer for the TEE subsystem (Sumit Garg)
 
  - Quite a significant modernization of the IXP4xx platforms by Linus
    Walleij, revisiting with a new PCI host driver/binding, removing legacy
    mach/* include dependencies and moving platform detection/config to
    drivers/soc. Also some updates/cleanup of platform data.
 
  - Core power domain support for Tegra platforms, and some improvements
    in build test coverage by adding stubs for compile test targets.
 
  - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
    support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
    and board fixups for iMX6/7.
 
  ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
  Rockchip.

383df634f1 More fallthrough fixes for Clang for 5.14-rc1
Hi Linus,
 
 Please, pull the following patches that fix many fall-through warnings
 when building with Clang 12.0.0 and this[1] change reverted. Notice
 that in order to enable -Wimplicit-fallthrough for Clang, such change[1]
 is meant to be reverted at some point. So, these patches help to move
 in that direction.
 
 Thanks!

757fa80f4e Tracing updates for 5.14:
- Added option for per CPU threads to the hwlat tracer
 
  - Have hwlat tracer handle hotplug CPUs
 
  - New tracer: osnoise, that detects latency caused by interrupts, softirqs
    and scheduling of other tasks.
 
  - Added timerlat tracer that creates a thread and measures in detail what
    sources of latency it has for wake ups.
 
  - Removed the "success" field of the sched_wakeup trace event.
    This has been hardcoded as "1" since 2015, no tooling should be looking
    at it now. If one exists, we can revert this commit, fix that tool and
    try to remove it again in the future.
 
  - tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
 
  - New boot command line option "tp_printk_stop", as tp_printk causes trace
    events to write to console. When user space starts, this can easily live
    lock the system. Having a boot option to stop just after boot up is
    useful to prevent that from happening.
 
  - Have ftrace_dump_on_oops boot command line option take numbers that match
    the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.
 
  - Bootconfig clean ups, fixes and enhancements.
 
  - New ktest script that tests bootconfig options.
 
  - Add tracepoint_probe_register_may_exist() to register a tracepoint
    without triggering a WARN*() if it already exists. BPF has a path from
    user space that can do this. All other paths are considered a bug.

78c14b385c treewide: Add missing semicolons to __assign_str uses
The __assign_str macro has an unusual ending semicolon but the vast
majority of uses of the macro already have semicolon termination.

$ git grep -P '\b__assign_str\b' | wc -l
551
$ git grep -P '\b__assign_str\b.*;' | wc -l
480

Add semicolons to the __assign_str() uses without semicolon termination
and all the other uses without semicolon termination via additional defines
that are equivalent to __assign_str() with the eventual goal of removing
the semicolon from the __assign_str() macro definition.

5a9b876e9d net: stmmac: option to enable PHY WOL with PMT enabled
The current stmmac driver WOL implementation will enable MAC WOL
if MAC HW PMT feature is on. Else, the driver will check for
PHY WOL support. There is another case where MAC HW PMT is
enabled but the platform still goes for the PHY WOL option.
E.g, Intel platform are designed for PHY WOL but not MAC WOL
although HW MAC PMT features are enabled.

Introduce use_phy_wol platform data to select PHY WOL
instead of depending on HW PMT features. Set use_phy_wol
will disable the plat->pmt which currently used to
determine the system to wake up by MAC WOL or PHY WOL.

Hi Linus,
 
 Please, pull the following patches that fix many fall-through warnings
 when building with Clang 12.0.0 and this[1] change reverted. Notice
 that in order to enable -Wimplicit-fallthrough for Clang, such change[1]
 is meant to be reverted at some point. So, these patches help to move
 in that direction.
 
 Thanks!

drivers/net/ethernet/microchip/sparx5/sparx5_main.c:760:29: warning:
variable 'mac_addr' is uninitialized when used here [-Wuninitialized]
        if (of_get_mac_address(np, mac_addr)) {

                    ^
                     = NULL
1 warning generated.

mac_addr is only used to store the value retrieved from
of_get_mac_address(), which is then copied into the base_mac member of
the sparx5 struct using ether_addr_copy(). It is easier to just use the
base_mac address directly, which avoids the warning and the extra copy.

7e8c18586d net: bridge: allow the switchdev replay functions to be called for deletion
When a switchdev port leaves a LAG that is a bridge port, the switchdev
objects and port attributes offloaded to that port are not removed:

ip link add br0 type bridge
ip link add bond0 type bond mode 802.3ad
ip link set swp0 master bond0
ip link set bond0 master br0
bridge vlan add dev bond0 vid 100
ip link set swp0 nomaster

VLAN 100 will remain installed on swp0 despite it going into standalone
mode, because as far as the bridge is concerned, nothing ever happened
to its bridge port.

Let's extend the bridge vlan, fdb and mdb replay functions to take a
'bool adding' argument, and make DSA and ocelot call the replay
functions with 'adding' as false from the switchdev unsync path, for the
switch port that leaves the bridge.

Note that this patch in itself does not salvage anything, because in the
current pull mode of operation, DSA still needs to call the replay
helpers with adding=false. This will be done in another patch.

0d2cfbd41c net: bridge: ignore switchdev events for LAG ports which didn't request replay
There is a slight inconvenience in the switchdev replay helpers added
recently, and this is when:

ip link add br0 type bridge
ip link add bond0 type bond
ip link set bond0 master br0
bridge vlan add dev bond0 vid 100
ip link set swp0 master bond0
ip link set swp1 master bond0

Since the underlying driver (currently only DSA) asks for a replay of
VLANs when swp0 and swp1 join the LAG because it is bridged, what will
happen is that DSA will try to react twice on the VLAN event for swp0.
This is not really a huge problem right now, because most drivers accept
duplicates since the bridge itself does, but it will become a problem
when we add support for replaying switchdev object deletions.

Let's fix this by adding a blank void *ctx in the replay helpers, which
will be passed on by the bridge in the switchdev notifications. If the
context is NULL, everything is the same as before. But if the context is
populated with a valid pointer, the underlying switchdev driver
(currently DSA) can use the pointer to 'see through' the bridge port
(which in the example above is bond0) and 'know' that the event is only
for a particular physical port offloading that bridge port, and not for
all of them.

69bfac968a net: switchdev: add a context void pointer to struct switchdev_notifier_info
In the case where the driver asks for a replay of a certain type of
event (port object or attribute) for a bridge port that is a LAG, it may
do so because this port has just joined the LAG.

But there might already be other switchdev ports in that LAG, and it is
preferable that those preexisting switchdev ports do not act upon the
replayed event.

The solution is to add a context to switchdev events, which is NULL most
of the time (when the bridge layer initiates the call) but which can be
set to a value controlled by the switchdev driver when a replay is
requested. The driver can then check the context to figure out if all
ports within the LAG should act upon the switchdev event, or just the
ones that match the context.

We have to modify all switchdev_handle_* helper functions as well as the
prototypes in the drivers that use these helpers too, because these
helpers hide the underlying struct switchdev_notifier_info from us and
there is no way to retrieve the context otherwise.

The context structure will be populated and used in later patches.

SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE notifications, but it implements just
the bridge bypass operations (.ndo_fdb_{add,del}). So the call to

       abuses.
 
  - Load-balancing changes:
 
      - Tweak newidle_balance for fair-sched, to improve
        'memcache'-like workloads.
 
      - "Age" (decay) average idle time, to better track & improve workloads

      - Fix & improve energy-aware (EAS) balancing logic & metrics.
 
      - Fix & improve the uclamp metrics.
 
      - Fix task migration (taskset) corner case on !CONFIG_CPUSET.
 
      - Fix RT and deadline utilization tracking across policy changes
 
      - Introduce a "burstable" CFS controller via cgroups, which allows
        bursty CPU-bound workloads to borrow a bit against their future
        quota to improve overall latencies & batching. Can be tweaked
