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.

When creating a PTP device, the configuration block allows
creation of an associated PPS device. However, there isn't
any way to associate the two devices after creation.
Set the PPS cookie, so pps_lookup_dev(ptp) performs correctly.

This patch introduces a function wrapper to call the sk_error_report
callback. That will prepare to add additional handling whenever
sk_error_report is called, for example to trace socket errors.

NUMA statistics are maintained on the zone level for hits, misses, foreign
etc but nothing relies on them being perfectly accurate for functional
correctness. The counters are used by userspace to get a general overview
of a workloads NUMA behaviour but the page allocator incurs a high cost to
maintain perfect accuracy similar to what is required for a vmstat like
NR_FREE_PAGES. There even is a sysctl vm.numa_stat to allow userspace to
turn off the collection of NUMA statistics like NUMA_HIT.
This patch converts NUMA_HIT and friends to be NUMA events with similar
accuracy to VM events. There is a possibility that slight errors will be
introduced but the overall trend as seen by userspace will be similar.
The counters are no longer updated from vmstat_refresh context as it is
unnecessary overhead for counters that may never be read by userspace.
Note that counters could be maintained at the node level to save space but
it would have a user-visible impact due to /proc/zoneinfo.

Use vma_lookup() to find the VMA at a specific address. As vma_lookup()
will return NULL if the address is not within any VMA, the start address
no longer needs to be validated.

vma_lookup() will look up the vma at a specific address. find_vma() will
start the search for a specific address and continue upwards. This fixes
an issue with the selftest as the returned vma may not be the newly
created vma, but simply the vma at a higher address.

The current code only associates with the existing blkcg when aio is used
to access the backing file. This patch covers all types of i/o to the
backing file and also associates the memcg so if the backing file is on
tmpfs, memory is charged appropriately.
This patch also exports cgroup_get_e_css and int_active_memcg so it can be
used by the loop module.

Patch series "Charge loop device i/o to issuing cgroup", v14.
The loop device runs all i/o to the backing file on a separate kworker
thread which results in all i/o being charged to the root cgroup. This
allows a loop device to be used to trivially bypass resource limits and
other policy. This patch series fixes this gap in accounting.
A simple script to demonstrate this behavior on cgroupv2 machine:
'''
#!/bin/bash
set -e
CGROUP=/sys/fs/cgroup/test.slice
LOOP_DEV=/dev/loop0
if [[ ! -d $CGROUP ]]
then
sudo mkdir $CGROUP
fi
grep oom_kill $CGROUP/memory.events
# Set a memory limit, write more than that limit to tmpfs -> OOM kill
sudo unshare -m bash -c "
echo \$\$ > $CGROUP/cgroup.procs;
echo 0 > $CGROUP/memory.swap.max;
echo 64M > $CGROUP/memory.max;
mount -t tmpfs -o size=512m tmpfs /tmp;
dd if=/dev/zero of=/tmp/file bs=1M count=256" || true
grep oom_kill $CGROUP/memory.events
# Set a memory limit, write more than that limit through loopback
# device -> no OOM kill
sudo unshare -m bash -c "
echo \$\$ > $CGROUP/cgroup.procs;
echo 0 > $CGROUP/memory.swap.max;
echo 64M > $CGROUP/memory.max;
mount -t tmpfs -o size=512m tmpfs /tmp;
truncate -s 512m /tmp/backing_file
losetup $LOOP_DEV /tmp/backing_file
dd if=/dev/zero of=$LOOP_DEV bs=1M count=256;
losetup -D $LOOP_DEV" || true
grep oom_kill $CGROUP/memory.events
'''
Naively charging cgroups could result in priority inversions through the
single kworker thread in the case where multiple cgroups are
reading/writing to the same loop device. This patch series does some
minor modification to the loop driver so that each cgroup can make forward
progress independently to avoid this inversion.
With this patch series applied, the above script triggers OOM kills when
writing through the loop device as expected.
This patch (of 3):
Existing uses of loop device may have multiple cgroups reading/writing to
the same device. Simply charging resources for I/O to the backing file
could result in priority inversion where one cgroup gets synchronously
blocked, holding up all other I/O to the loop device.
In order to avoid this priority inversion, we use a single workqueue where
each work item is a "struct loop_worker" which contains a queue of struct
loop_cmds to issue. The loop device maintains a tree mapping blk css_id
-> loop_worker. This allows each cgroup to independently make forward
progress issuing I/O to the backing file.
There is also a single queue for I/O associated with the rootcg which can
be used in cases of extreme memory shortage where we cannot allocate a
loop_worker.
The locking for the tree and queues is fairly heavy handed - we acquire a
per-loop-device spinlock any time either is accessed. The existing
implementation serializes all I/O through a single thread anyways, so I
don't believe this is any worse.

Use __set_page_dirty_no_writeback() instead. This will set the dirty bit
on the page, which will be used to avoid calling set_page_dirty() in the
future. It will have no effect on actually writing the page back, as the
pages are not on any LRU lists.

The page reporting won't be triggered if the freeing page can't come up
with a free area, whose size is equal or bigger than the threshold (page
reporting order). The default page reporting order, equal to
@pageblock_order, is too huge on some architectures to trigger page
reporting. One example is ARM64 when 64KB base page size is used.
PAGE_SIZE: 64KB
pageblock_order: 13 (512MB)
MAX_ORDER: 14
This specifies the page reporting order to 5 (2MB) for this specific case
so that page reporting can be triggered.

Currently firmware passes CCF specific flags to ZynqMP clock driver.
So firmware needs to be updated if CCF flags are changed. The firmware
should have its own 'flag number space' that is distinct from the
common clk framework's 'flag number space'. So define and use ZynqMP
specific common clock flags instead of using CCF flags.

Platform STM32MP1 can be used in configuration where some clock
resources cannot be accessed by Linux kernel when executing in non-secure
state of the CPU(s).
In such configuration, the RCC clock driver must not register clocks
it cannot access.
They are expected to be registered from another clock driver such
as the SCMI clock driver.
This change uses specific compatible string "st,stm32mp1-rcc-secure"
to specify RCC clock driver configuration where RCC is secure.

Clang warns:
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)) {

u8 *mac_addr;

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.

The SJA1105P/Q/R/S and SJA1110 may have the same layout for the command
to read/write/search for L2 Address Lookup entries, but as explained in
the comments at the beginning of the sja1105_dynamic_config.c file, the
command portion of the buffer is at the end, and we need to obtain a
pointer to it by adding the length of the entry to the buffer.
Alas, the length of an L2 Address Lookup entry is larger in SJA1110 than
it is for SJA1105P/Q/R/S, so we need to create a common helper to access
the command buffer, and this receives as argument the length of the
entry buffer.

AR8031/AR8033 have different status registers for copper
and fiber operation. However, the extended status register
is the same for both operation modes.
As a result of that, ESTATUS_1000_XFULL is set to 1 even when
operating in copper TP mode.
Remove this mode from the supported link modes, as this driver
currently only supports copper operation.

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.
