The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the

Currently net_secret_init does not get inlined, so we always have a call
to net_secret_init even in the fast path.
Let's specify net_secret_init as __always_inline so we have the nop in
the fast-path without the call to net_secret_init and the unlikely path
at the epilogue of the function.
jump_labels handle the inlining correctly.

2e685cad57 (tcp_memcontrol: Kill struct tcp_memcontrol) falsly modified
the access to memory_pressure of sk->sk_prot->memory_pressure. The patch
did modify the memory_pressure-field of struct cg_proto, but not the one
of struct proto.
So, the access to sk_prot->memory_pressure should not be changed.

After the commit below attempting to create macvlan devices was
resulting in ENOENT errors,
# ip link add link p3p2 type macvlan
RTNETLINK answers: Invalid argument
This happens because netdev_upper_dev_link() is called before
register_netdevice() in the macvlan code. Through a call chain
this results in a call to __netdev_adjacent_dev_insert() and
finally a sysfs_create_link(). This requires the kobject of
the macvlan to be registered which is done in register_netdevice().
If there is no kobject which is the case here the ENOENT error
is seen on the command line.
To resolve this move the netdev_upper_dev_link() call below
the register_netdevice() call. This aligns with vlan driver
flow.
Regression introduced here,

As Jiri noted, currently we first do all bonding-specific initialization
(specifically - bond_select_active_slave(bond)) before we actually attach
the slave (so that it becomes visible through bond_for_each_slave() and
friends). This might result in bond_select_active_slave() not seeing the
first/new slave and, thus, not actually selecting an active slave.
Fix this by moving all the bond-related init part after we've actually
completely initialized and linked (via bond_master_upper_dev_link()) the
new slave.
Also, remove the bond_(de/a)ttach_slave(), it's useless to have functions
to ++/-- one int.
After this we have all the initialization of the new slave *before*
linking, and all the stuff that needs to be done on bonding *after* it. It
has also a bonus effect - we can remove the locking on the new slave init
completely, and only use it for bond_select_active_slave().

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to i40e only.
Jesse provides 6 patches against i40e. First is a patch to reduce
CPU utilization by reducing read-flush to read in the hot path. Next
couple of patches resolve coverity issues reported by Hannes Frederic
Sowa <hannes@stressinduktion.org>. Then Jesse refactored i40e to cleanup
functions which used cpu_to_xxx(foo) which caused a lot of line wrapping.
Mitch provides 2 i40e patches. First fixes a panic when tx_rings[0]
are not allocated, his second patch corrects a math error when
assigning MSI-X vectors to VFs. The vectors-per-vf value reported
by the hardware already conveniently reports one less than the actual
value.
Shannon provides 5 patches against i40e. His first patch corrects a
number of little bugs in the error handling of irq setup, most of
which ended up panicing the kernel. Next he fixes the overactive
IRQ issue seen in testing and allows the use of the legacy interrupt.
Shannon then provides a cleanup of the arguments declared at the
beginning of each function. Then he provides a patch to make sure
that there are really rings and queues before trying to dump
information in them. Lastly he simplifies the code by using an
already existing variable.
Catherine provides an i40e patch to bump the version.
v2:
- Remove unneeded parenthesis in patch 3 based on feedback from
Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>
- Fix patch description for patch 11 based on feedback from
Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

While this commit was a good attempt to fix issues occuring when no
multicast querier is present, this commit still has two more issues:
1) There are cases where mdb entries do not expire even if there is a
querier present. The bridge will unnecessarily continue flooding
multicast packets on the according ports.
2) Never removing an mdb entry could be exploited for a Denial of
Service by an attacker on the local link, slowly, but steadily eating up
all memory.
Actually, this commit became obsolete with
"bridge: disable snooping if there is no querier" (b00589af3b)
which included fixes for a few more cases.
Therefore reverting the following commits (the commit stated in the
commit message plus three of its follow up fixes):
====================
Revert "bridge: update mdb expiration timer upon reports."
This reverts commit f144febd93d5ee534fdf23505ab091b2b9088edc.
Revert "bridge: do not call setup_timer() multiple times"
This reverts commit 1faabf2aab1fdaa1ace4e8c829d1b9cf7bfec2f1.
Revert "bridge: fix some kernel warning in multicast timer"
This reverts commit c7e8e8a8f7a70b343ca1e0f90a31e35ab2d16de1.
Revert "bridge: only expire the mdb entry when query is received"
This reverts commit 9f00b2e7cf241fa389733d41b615efdaa2cb0f5b.

The result of the store-clock-fast (STCKF) instruction is a bit fuzzy.
It can happen that the value stored on one CPU is smaller than the value
stored on another CPU, although the order of the stores is the other
way around. This can cause deltas of get_tod_clock() values to become
negative when they should not be.
We need to be more careful with store-clock-fast, this patch partially
reverts git commit e4b7b4238e666682555461fa52eecd74652f36bb "time:
always use stckf instead of stck if available". The get_tod_clock()
function now uses the store-clock-extended (STCKE) instruction.
get_tod_clock_fast() can be used if the fuzziness of store-clock-fast
is acceptable e.g. for wait loops local to a CPU.
