Since act_pedit now has access to percpu counters, use the
tcf_action_inc_overlimit_qstats wrapper that will use the percpu
counter whenever they are available.

The kernel stack can be more consistent by printing the IFF_PROMISC
aka promiscuous enable/disable messages with the standard netdev_info
message which can include bus and driver info as well as the device.
typical command usage from user space looks like:
ip link set eth0 promisc <on|off>
But lots of utilities such as bridge, tcpdump, etc put the interface into
promiscuous mode.
old message:
[ 406.034418] device eth0 entered promiscuous mode
[ 408.424703] device eth0 left promiscuous mode
new message:
[ 406.034431] ice 0000:17:00.0 eth0: entered promiscuous mode
[ 408.424715] ice 0000:17:00.0 eth0: left promiscuous mode

When the user sets or clears the IFF_ALLMULTI flag in the netdev, there are
no log messages printed to the kernel log to indicate anything happened.
This is inexplicably different from most other dev->flags changes, and
could suprise the user.
Typically this occurs from user-space when a user:
ip link set eth0 allmulticast <on|off>
However, other devices like bridge set allmulticast as well, and many
other flows might trigger entry into allmulticast as well.
The new message uses the standard netdev_info print and looks like:
[ 413.246110] ixgbe 0000:17:00.0 eth0: entered allmulticast mode
[ 415.977184] ixgbe 0000:17:00.0 eth0: left allmulticast mode

MSG_ZEROCOPY ensures that pinned user pages do not exceed the limit.
If no limit is set, skip this accounting as otherwise expensive
atomic_long operations are called for no reason.
This accounting is already skipped for privileged (CAP_IPC_LOCK)
users. Rely on the same mechanism: if no mmp->user is set,
mm_unaccount_pinned_pages does not decrement either.

In fixed-link setup phylink_parse_fixedlink() unconditionally sets
Pause, Asym_Pause and Autoneg bits to "supported" bitmap, while MAC may

This leads to ethtool reporting:

> Supports auto-negotiation: Yes
regardless of what is actually supported.
Instead of unconditionally set Pause, Asym_Pause and Autoneg it is
sensible to set them according to validated "supported" bitmap, i.e. the

Define the fields within the CH_C_QOS GSI register using an array of
field masks in that register's reg structure. Use the reg functions
for encoding values in those fields.
One field in the register is present for IPA v4.0-4.2 only, two
others are present starting at IPA v4.5, and one more is there
starting at IPA v4.9.
Drop the "GSI_" prefix in symbols defined in the gsi_prefetch_mode
enumerated type, and define their values using decimal rather than
hexidecimal values.
