"This week we have a single fix: replacing smp_mb() with __smp_mb().
We were the only architecture with smp_mb() and it appears to just be
clearly wrong, so I think this is a pretty safe patch for an RC"
* tag 'riscv-for-linus-4.16-rc4_smp_mb' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux:
riscv/barrier: Define __smp_{mb,rmb,wmb}
On CPU hotunplug the enqueued timers of the unplugged CPU are migrated to a
live CPU. This happens from the control thread which initiated the unplug.
If the CPU on which the control thread runs came out from a longer idle
period then the base clock of that CPU might be stale because the control
thread runs prior to any event which forwards the clock.
In such a case the timers from the unplugged CPU are queued on the live CPU
based on the stale clock which can cause large delays due to increased
granularity of the outer timer wheels which are far away from base:;clock.
But there is a worse problem than that. The following sequence of events
illustrates it:
- CPU0 timer1 is queued expires = 59969 and base->clk = 59131.
The timer is queued at wheel level 2, with resulting expiry time = 60032
(due to level granularity).
- CPU1 enters idle @60007, with next timer expiry @60020.
- CPU0 is hotplugged at @60009
- CPU1 exits idle and runs the control thread which migrates the
timers from CPU0
timer1 is now queued in level 0 for immediate handling in the next
softirq because the requested expiry time 59969 is before CPU1 base->clk
60007
- CPU1 runs code which forwards the base clock which succeeds because the
next expiring timer. which was collected at idle entry time is still set
to 60020.
So it forwards beyond 60007 and therefore misses to expire the migrated
timer1. That timer gets expired when the wheel wraps around again, which
takes between 63 and 630ms depending on the HZ setting.
Address both problems by invoking forward_timer_base() for the control CPUs
timer base. All other places, which might run into a similar problem
(mod_timer()/add_timer_on()) already invoke forward_timer_base() to avoid
that.

A toolstack may delete the vif frontend and backend xenstore entries
while xen-netfront is in the removal code path. In that case, the
checks for xenbus_read_driver_state would return XenbusStateUnknown, and
xennet_remove would hang indefinitely. This hang prevents system
shutdown.
xennet_remove must be able to handle XenbusStateUnknown, and
netback_changed must also wake up the wake_queue for that state as well.

Current cleanup in the error path of xen_bind_pirq_msi_to_irq is
wrong. First of all there's an off-by-one in the cleanup loop, which
can lead to unbinding wrong IRQs.
Secondly IRQs not bound won't be freed, thus leaking IRQ numbers.
Note that there's no need to differentiate between bound and unbound
IRQs when freeing them, __unbind_from_irq will deal with both of them
correctly.

The IPS_NAT_MASK check in 4.12 replaced previous check for nfct_nat()
which was needed to fix a crash in 2.6.36-rc, see
commit 7bcbf81a22 ("ipvs: avoid oops for passive FTP").
But as IPVS does not set the IPS_SRC_NAT and IPS_DST_NAT bits,
checking for IPS_NAT_MASK prevents PASV response to be properly
mangled and blocks the transfer. Remove the check as it is not
needed after 3.12 commit 41d73ec053 ("netfilter: nf_conntrack:
make sequence number adjustments usuable without NAT") which
changes nfct_nat() with nfct_seqadj() and especially after 3.13

In SMP systems, GFRC is used for clocksource. However by default the
counter keeps running even when core is halted (say when debugging via a
JTAG debugger). This confuses Linux timekeeping and triggers flase RCU stall
splat such as below:

| Running with 1000 processes for 1000 objects
| hrtimer: interrupt took 485060 ns

| (detected by 1, t=13648 jiffies, g=31493, c=31492, q=1)
Starting from ARC HS v3.0 it's possible to tie GFRC to state of up-to 4
ARC cores with help of GFRC's CORE register where we set a mask for
cores which state we need to rely on.
We update cpu mask every time new cpu came online instead of using
hardcoded one or using mask generated from "possible_cpus" as we
want it set correctly even if we run kernel on HW which has fewer cores
than expected (or we launch kernel via debugger and kick fever cores
than HW has)
Note that GFRC halts when all cores have halted and thus relies on
programming of Inter-Core-dEbug register to halt all cores when one
halts.

One of the basic construct in the device is a port-VLAN pair, which can
be bound to a FID or a RIF in order to direct packets to the bridge or
the router, respectively.
Since not all the netdevs are configured with a VLAN (e.g., sw1p1 vs.
sw1p1.10), VID 1 is used to represent these and thus this VID can be
used by both upper devices of mlxsw ports and by the driver itself.
However, this VID is not reference counted and therefore might be freed
prematurely, which can result in various WARNINGs. For example:
$ ip link add name br0 type bridge vlan_filtering 1
$ teamd -t team0 -d -c '{"runner": {"name": "lacp"}}'
$ ip link set dev team0 master br0
$ ip link set dev enp1s0np1 master team0
$ ip address add 192.0.2.1/24 dev enp1s0np1
The enslavement to team0 will fail because team0 already has an upper
and thus vlan_vids_del_by_dev() will be executed as part of team's error
path which will delete VID 1 from enp1s0np1 (added by br0 as PVID). The
WARNING will be generated when the driver will realize it can't find VID
1 on the port and bind it to a RIF.
Fix this by adding a reference count to the VLAN entries on the port, in
a similar fashion to the reference counting used by the corresponding
'vlan_vid_info' structure in the 8021q driver.

When multicast snooping is enabled, the Linux bridge resorts to flooding
unregistered multicast packets to all ports only in case it did not
detect a querier in the network.
The above condition is not reflected to underlying drivers, which is
especially problematic in IPv6 environments, as multicast snooping is
enabled by default and since neighbour solicitation packets might be
treated as unregistered multicast packets in case there is no
corresponding MDB entry.
Until the Linux bridge reflects its querier state to underlying drivers,
simply treat unregistered multicast packets as broadcast and allow them
to reach their destination.

When the Intel Edison module is powered with 3.3V, the reboot command makes
the module stuck. If the module is powered at a greater voltage, like 4.4V
(as the Edison Mini Breakout board does), reboot works OK.
The official Intel Edison BSP sends the IPCMSG_COLD_RESET message to the
SCU by default. The IPCMSG_COLD_BOOT which is used by the upstream kernel
is only sent when explicitely selected on the kernel command line.
Use IPCMSG_COLD_RESET unconditionally which makes reboot work independent
of the power supply voltage.
