NAPI poll logic now enforces that a poller returns exactly the budget
when it wants to be called again.
If a driver limits TX completion, it has to return budget as well when
the limit is hit, not the number of received packets.

is done only when work_done == budget. When we are in busy_poll we return 0 in
napi_poll. We should return budget.

The driver connects and disconnects the PHY device whenever the
net device is brought up and down. The ethtool get_settings,
set_settings and nway_reset operations will dereference a null
or dangling pointer if called while it is down.
I think it would be preferable to keep the PHY connected, but there
may be good reasons not to.
As an immediate fix for this bug:
- Set the phydev pointer to NULL after disconnecting the PHY
- Change those three operations to return -ENODEV while the PHY is
not connected

Currently net_device_ops::set_rx_mode is only implemented for
chips with a TSU (multiple address table). However we do need
to turn the PRM (promiscuous) flag on and off for other chips.
- Remove the unlikely() from the TSU functions that we may safely
call for chips without a TSU
- Make setting of the MCT flag conditional on the tsu capability flag
- Rename sh_eth_set_multicast_list() to sh_eth_set_rx_mode() and plumb
it into both net_device_ops structures
- Remove the previously-unreachable branch in sh_eth_rx_mode() that
would otherwise reset the flags to defaults for non-TSU chips

To fix invalid hardware accesses, the commit 872b5d814f ("ath9k: do not
access hardware on IRQs during reset") made the irq handler ignore interrupts
emitted after queueing a hardware reset (which disables the IRQ). This left a
small time window for the IRQ to get re-enabled by the tasklet, which caused
IRQ storms. Instead of returning IRQ_NONE when ATH_OP_HW_RESET is set, disable
the IRQ entirely for the duration of the reset.

* one fix for rfkill while scheduled scan is running.
Linus's system hit this issue. WiFi would be unavailable
after this has happpened because of bad state in cfg80211.
When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.
To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.
This is basically the same as:
commit 9b520d8495

I.e. one-to-many sockets in SCTP are not required to explicitly
call into connect(2) or sctp_connectx(2) prior to data exchange.
Instead, they can directly invoke sendmsg(2) and the SCTP stack
will automatically trigger connection establishment through 4WHS
via sctp_primitive_ASSOCIATE(). However, this in its current
implementation is racy: INIT is being sent out immediately (as
it cannot be bundled anyway) and the rest of the DATA chunks are
queued up for later xmit when connection is established, meaning
sendmsg(2) will return successfully. This behaviour can result
in an undesired side-effect that the kernel made the application
think the data has already been transmitted, although none of it
has actually left the machine, worst case even after close(2)'ing
the socket.
Instead, when the association from client side has been shut down
e.g. first gracefully through SCTP_EOF and then close(2), the
client could afterwards still receive the server's INIT_ACK due
to a connection with higher latency. This INIT_ACK is then considered
out of the blue and hence responded with ABORT as there was no
alive assoc found anymore. This can be easily reproduced f.e.
with sctp_test application from lksctp. One way to fix this race
is to wait for the handshake to actually complete.
The fix defers waiting after sctp_primitive_ASSOCIATE() and
sctp_primitive_SEND() succeeded, so that DATA chunks cooked up
from sctp_sendmsg() have already been placed into the output
queue through the side-effect interpreter, and therefore can then
be bundeled together with COOKIE_ECHO control chunks.

This reverts commit da788acb28.
That commit tried to fix the section mismatch warning by moving the
ppc_corenet_clk_driver struct to init section. This is definitely wrong
because the kernel would free the memories occupied by this struct
after boot while this driver is still registered in the driver core.
The kernel would panic when accessing this driver struct.

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.
It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.
Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

In addition to the problem Jeff Layton reported, I looked at the code
and reproduced the same warning by subscribing and removing the genl
family with a socket still open. This is a fairly tricky race which
originates in the fact that generic netlink allows the family to go
away while sockets are still open - unlike regular netlink which has
a module refcount for every open socket so in general this cannot be
triggered.
Trying to resolve this issue by the obvious locking isn't possible as
it will result in deadlocks between unregistration and group unbind
notification (which incidentally lockdep doesn't find due to the home
grown locking in the netlink table.)
To really resolve this, introduce a "closing socket" reference counter
(for generic netlink only, as it's the only affected family) in the
core netlink code and use that in generic netlink to wait for all the
sockets that are being closed at the same time as a generic netlink
family is removed.
This fixes the race that when a socket is closed, it will should call
the unbind, but if the family is removed at the same time the unbind
will not find it, leading to the warning. The real problem though is
that in this case the unbind could actually find a new family that is
registered to have a multicast group with the same ID, and call its
mcast_unbind() leading to confusing.
Also remove the warning since it would still trigger, but is now no
longer a problem.
This also moves the code in af_netlink.c to before unreferencing the
module to avoid having the same problem in the normal non-genl case.
