Pull memremap fix from Dan Williams:
"The new memremap() api introduced in the 4.3 cycle to unify/replace
ioremap_cache() and ioremap_wt() is mishandling the highmem case.
This patch has received a build success notification from a

This patch changes the use of struct timespec in
dccp_probe to use struct timespec64 instead. timespec uses a 32-bit
seconds field which will overflow in the year 2038 and beyond. timespec64
uses a 64-bit seconds field. Note that the correctness of the code isn't
changed, since the original code only uses the timestamps to compute a
small elapsed interval. This patch is part of a larger attempt to remove
instances of 32-bit timekeeping structures (timespec, timeval, time_t)
from the kernel so it is easier to identify where the real 2038 issues
are.

====================
ipv4: fix problems from the RTNH_F_LINKDOWN introduction
Fix two problems from the change that introduced RTNH_F_LINKDOWN
flag. The first patch deals with the removal of local route on
DOWN event. The second patch makes sure the RTNH_F_LINKDOWN
flag is properly updated on UP event because the DOWN event
sets it in all cases.
v2->v3:
- use bool for force var
v1->v2:
- forgot to add ifconfig dummy0 down in the test case
- split to 2 patches

When nexthop is part of multipath route we should clear the
LINKDOWN flag when link goes UP or when first address is added.
This is needed because we always set LINKDOWN flag when DEAD flag
was set but now on UP the nexthop is not dead anymore. Examples when
LINKDOWN bit can be forgotten when no NETDEV_CHANGE is delivered:
- link goes down (LINKDOWN is set), then link goes UP and device
shows carrier OK but LINKDOWN remains set
- last address is deleted (LINKDOWN is set), then address is
added and device shows carrier OK but LINKDOWN remains set
Steps to reproduce:
modprobe dummy
ifconfig dummy0 192.168.168.1 up
here add a multipath route where one nexthop is for dummy0:
ip route add 1.2.3.4 nexthop dummy0 nexthop SOME_OTHER_DEVICE
ifconfig dummy0 down
ifconfig dummy0 up
now ip route shows nexthop that is not dead. Now set the sysctl var:
echo 1 > /proc/sys/net/ipv4/conf/dummy0/ignore_routes_with_linkdown
now ip route will show a dead nexthop because the forgotten
RTNH_F_LINKDOWN is propagated as RTNH_F_DEAD.

When fib_netdev_event calls fib_disable_ip on NETDEV_DOWN event
we should not delete the local routes if the local address
is still present. The confusion comes from the fact that both
fib_netdev_event and fib_inetaddr_event use the NETDEV_DOWN
constant. Fix it by returning back the variable 'force'.
Steps to reproduce:
modprobe dummy
ifconfig dummy0 192.168.168.1 up
ifconfig dummy0 down
ip route list table local | grep dummy | grep host
local 192.168.168.1 dev dummy0 proto kernel scope host src 192.168.168.1

The SS_LISTEN socket state is defined by both af_vsock.c and
vmci_transport.c. This is risky since the value could be changed in one
file and the other would be out of sync.
Rename from SS_LISTEN to VSOCK_SS_LISTEN since the constant is not part
of enum socket_state (SS_CONNECTED, ...). This way it is clear that the
constant is vsock-specific.
The big text reflow in af_vsock.c was necessary to keep to the maximum
line length. Text is unchanged except for s/SS_LISTEN/VSOCK_SS_LISTEN/.

On certain hardware in certain situations loopback test fails and the
driver gets removed. During mdiobus_unregister() instance of PHY driver
gets disposed. But by this time it has already been started using
phy_connect_direct().
PHY driver uses DELAYED_WORK in order to maintain its state. Attempting
to dispose the driver without calling phy_disconnect() causes deallocation
of DELAYED_WORK being active. This shortly causes a bad crash in timer
code.
The problem can be discovered by enabling CONFIG_DEBUG_OBJECTS_TIMERS and

Testing of the new UDP bearer has revealed that reception of
NAME_DISTRIBUTOR, LINK_PROTOCOL/RESET and LINK_PROTOCOL/ACTIVATE
message buffers is not prepared for the case that those may be
non-linear.
We now linearize all such buffers before they are delivered up to the
generic reception layer.
In order for the commit to apply cleanly to 'net' and 'stable', we do
the change in the function tipc_udp_recv() for now. Later, we will post
a commit to 'net-next' moving the linearization to generic code, in
tipc_named_rcv() and tipc_link_proto_rcv().

net: clean up interactions of CHECKSUM_PARTIAL and fragmentation
This series fixes wrong checksums on the wire for IPv4 and IPv6. Large

We cannot reliable calculate packet size on MSG_MORE corked sockets
and thus cannot decide if they are going to be fragmented later on,
so better not use CHECKSUM_PARTIAL in the first place.
The IPv6 code also intended to protect and not use CHECKSUM_PARTIAL in
the existence of IPv6 extension headers, but the condition was wrong. Fix
it up, too. Also the condition to check whether the packet fits into
one fragment was wrong and has been corrected.

We clear the close-on-exec flag when opening and closing files, and the
bit was almost always already clear before. Avoid dirtying the
cacheline if the clearning isn't necessary. That avoids unnecessary
cacheline dirtying and bouncing in multi-socket environments.
Eric Dumazet has a file descriptor benchmark that goes 4% faster from
this on his two-socket machine. It's probably partly superlinear
improvement due to getting slightly less spinlock contention on the
file_lock spinlock due to less work in the critical section.

And Eric Dumazet has a somewhat realistic multithreaded microbenchmark
that opens and closes a lot of sockets with minimal work per socket.
This patch largely fixes it. We keep a 2nd-level bitmap of the open
file bitmaps, showing which words are already full. So then we can
traverse that second-level bitmap to efficiently skip already allocated
file descriptors.
On his benchmark, this improves performance by up to an order of
magnitude, by avoiding the excessive open file bitmap scanning.

In Microsoft Surface3 the GPIO detecting lid state is shared between GPIO
event and operation region. Below is simplied version of the DSDT from
Surface3 including relevant parts:
Scope (GPO0)
{
Name (_AEI, ResourceTemplate ()
{
GpioInt (Edge, ActiveBoth, Shared, PullNone, 0x0000,
"\\_SB.GPO0", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x004C
}
})
OperationRegion (GPOR, GeneralPurposeIo, Zero, One)
Field (GPOR, ByteAcc, NoLock, Preserve)
{
Connection (
GpioIo (Shared, PullNone, 0x0000, 0x0000,
IoRestrictionNone, "\\_SB.GPO0", 0x00,
ResourceConsumer,,)
{ // Pin list
0x004C
}
),
HELD, 1
}
Method (_E4C, 0, Serialized) // _Exx: Edge-Triggered GPE
{
If ((HELD == One))
{
^^LID.LIDB = One
}
Else
{
^^LID.LIDB = Zero
Notify (LID, 0x80) // Status Change
}
Notify (^^PCI0.SPI1.NTRG, One) // Device Check
}
}
When GPIO 0x4c changes we call ASL method _E4C which tries to read HELD
field (the same GPIO). This triggers following error on the console:
ACPI Error: Method parse/execution failed [\_SB.GPO0._E4C]
(Node ffff88013f4b4438), AE_ERROR (20150930/psparse-542)
The error happens because ACPI GPIO operation region handler
(acpi_gpio_adr_space_handler()) tries to acquire the very same GPIO which
returns an error (-EBUSY) because the GPIO is already reserved for the GPIO
event.
Fix this so that we "borrow" the event GPIO if we find the GPIO belongs to
an event. Allow this only for GPIOs that are read.
To be able to go through acpi_gpio->events list for operation region access
we need to make sure the list is properly initialized whenever GPIO chip is
registered.
