Previously, without GSO, it was easy to identify it: if the chunk didn't
fit and there was no data chunk in the packet yet, we could fragment at
IP level. So if there was an auth chunk and we were bundling a big data
chunk, it would fragment regardless of the size of the auth chunk. This
also works for the context of PMTU reductions.
But with GSO, we cannot distinguish such PMTU events anymore, as the
packet is allowed to exceed PMTU.
So we need another check: to ensure that the chunk that we are adding,
actually fits the current PMTU. If it doesn't, trigger a flush and let
it be fragmented at IP level in the next round.

Bad blocks can be injected via /sys/block/pmemN/badblocks. In a situation
where legacy pmem is being used or a pmem region created by using memmap
kernel parameter, the injected bad blocks are not cleared due to
nvdimm_clear_poison() failing from lack of ndctl function pointer. In
this case we need to just return as handled and allow the bad blocks to
be cleared rather than fail.

track_pfn_insert() in vmf_insert_pfn_pmd() is marking dax mappings as
uncacheable rendering them impractical for application usage. DAX-pte
mappings are cached and the goal of establishing DAX-pmd mappings is to
attain more performance, not dramatically less (3 orders of magnitude).
track_pfn_insert() relies on a previous call to reserve_memtype() to
establish the expected page_cache_mode for the range. While memremap()
arranges for reserve_memtype() to be called, devm_memremap_pages() does
not. So, teach track_pfn_insert() and untrack_pfn() how to handle
tracking without a vma, and arrange for devm_memremap_pages() to
establish the write-back-cache reservation in the memtype tree.

ip: fix creation flags reported in RTM_NEWROUTE events
Netlink messages sent to user-space upon RTM_NEWROUTE events have their
nlmsg_flags field inconsistently set. While the NLM_F_REPLACE and
NLM_F_APPEND bits are correctly handled, NLM_F_CREATE and NLM_F_EXCL
are always 0.
This series sets the NLM_F_CREATE and NLM_F_EXCL bits when applicable,
for IPv4 and IPv6.
Since IPv6 ignores the NLM_F_APPEND flags in requests, this flag isn't
reported in RTM_NEWROUTE IPv6 events. This keeps IPv6 internal
consistency (same flag semantic for user requests and kernel events) at
the cost of bringing different flag interpretation for IPv4 and IPv6.

Since commit 37a1d3611c12 ("ipv6: include NLM_F_REPLACE in route
replace notifications"), RTM_NEWROUTE notifications have their
NLM_F_REPLACE flag set if the new route replaced a preexisting one.
However, other flags aren't set.
This patch reports the missing NLM_F_CREATE and NLM_F_EXCL flag bits.
NLM_F_APPEND is not reported, because in ipv6 a NLM_F_CREATE request
is interpreted as an append request (contrary to ipv4, "prepend" is not
supported, so if NLM_F_EXCL is not set then NLM_F_APPEND is implicit).
As a result, the possible flag combination can now be reported
(iproute2's terminology into parentheses):
* NLM_F_CREATE | NLM_F_EXCL: route didn't exist, exclusive creation
("add").
* NLM_F_CREATE: route did already exist, new route added after
preexisting ones ("append").
* NLM_F_REPLACE: route did already exist, new route replaced the
first preexisting one ("change").

fib_table_insert() inconsistently fills the nlmsg_flags field in its
notification messages.
Since commit b8f558313506 ("[RTNETLINK]: Fix sending netlink message
when replace route."), the netlink message has its nlmsg_flags set to
NLM_F_REPLACE if the route replaced a preexisting one.
Then commit a2bb6d7d6f42 ("ipv4: include NLM_F_APPEND flag in append
route notifications") started setting nlmsg_flags to NLM_F_APPEND if
the route matched a preexisting one but was appended.
In other cases (exclusive creation or prepend), nlmsg_flags is 0.
This patch sets ->nlmsg_flags in all situations, preserving the
semantic of the NLM_F_* bits:
* NLM_F_CREATE: a new fib entry has been created for this route.
* NLM_F_EXCL: no other fib entry existed for this route.
* NLM_F_REPLACE: this route has overwritten a preexisting fib entry.
* NLM_F_APPEND: the new fib entry was added after other entries for
the same route.
As a result, the possible flag combination can now be reported
(iproute2's terminology into parentheses):
* NLM_F_CREATE | NLM_F_EXCL: route didn't exist, exclusive creation
("add").
* NLM_F_CREATE | NLM_F_APPEND: route did already exist, new route
added after preexisting ones ("append").
* NLM_F_CREATE: route did already exist, new route added before
preexisting ones ("prepend").
* NLM_F_REPLACE: route did already exist, new route replaced the
first preexisting one ("change").

The resent conversion of the cpu hotplug support in the uncore driver
introduced a regression due to the way the callbacks are invoked at
initialization time.
The old code called the prepare/starting/online function on each online cpu
as a block. The new code registers the hotplug callbacks in the core for
each state. The core invokes the callbacks at each registration on all
online cpus.
The code implicitely relied on the prepare/starting/online callbacks being
called as combo on a particular cpu, which was not obvious and completely
undocumented.
The resulting subtle wreckage happens due to the way how the uncore code
manages shared data structures for cpus which share an uncore resource in
hardware. The sharing is determined in the cpu starting callback, but the
prepare callback allocates per cpu data for the upcoming cpu because
potential sharing is unknown at this point. If the starting callback finds
a online cpu which shares the hardware resource it takes a refcount on the
percpu data of that cpu and puts the own data structure into a
'free_at_online' pointer of that shared data structure. The online callback
frees that.
With the old model this worked because in a starting callback only one non
unused structure (the one of the starting cpu) was available. The new code
allocates the data structures for all cpus when the prepare callback is
registered.
Now the starting function iterates through all online cpus and looks for a
data structure (skipping its own) which has a matching hardware id. The id
member of the data structure is initialized to 0, but the hardware id can
be 0 as well. The resulting wreckage is:
CPU0 finds a matching id on CPU1, takes a refcount on CPU1 data and puts
its own data structure into CPU1s data structure to be freed.
CPU1 skips CPU0 because the data structure is its allegedly unsued own.
It finds a matching id on CPU2, takes a refcount on CPU1 data and puts
its own data structure into CPU2s data structure to be freed.
....
Now the online callbacks are invoked.
CPU0 has a pointer to CPU1s data and frees the original CPU0 data. So
far so good.
CPU1 has a pointer to CPU2s data and frees the original CPU1 data, which
is still referenced by CPU0 ---> Booom
So there are two issues to be solved here:
1) The id field must be initialized at allocation time to a value which
cannot be a valid hardware id, i.e. -1
This prevents the above scenario, but now CPU1 and CPU2 both stick their
own data structure into the free_at_online pointer of CPU0. So we leak
CPU1s data structure.
2) Fix the memory leak described in #1
Instead of having a single pointer, use a hlist to enqueue the
superflous data structures which are then freed by the first cpu
invoking the online callback.
Ideally we should know the sharing _before_ invoking the prepare callback,
but that's way beyond the scope of this bug fix.

This file is included from DTS files under arch/arm64 too (via
broadcom/bcm2837-rpi-3-b.dts and broadcom/bcm2837.dtsi). There is a desire
not to have skeleton.dtsi for ARM64. See commit 3ebee5a2e141 ("arm64: dts:
kill skeleton.dtsi") for rationale for its removal.
As well as the addition of #*-cells also requires adding the device_type to
the rpi memory node explicitly.
Note that this change results in the removal of an empty /aliases node from
bcm2835-rpi-a.dtb and bcm2835-rpi-a-plus.dtb. I have no hardware to check
if this is a problem or not.
It also results in some reordering of the nodes in the DTBs (the /aliases
and /memory nodes come later). This isn't supposed to matter but, again,

Although the validation of queues_total and queuenum is checked in nft
utility, but user can add nft rules via nfnetlink, so it is necessary
to check the validation at the nft_queue expr init routine too.

Don't return the confusing -EIO error code when the device is not registered,
instead return -ENODEV which is the proper thing to do in this situation.

If the adapter is configured as 'Unregistered', then cec_receive_notify
incorrectly thinks that broadcast messages are directed messages. The
destination for broadcast messages is 0xf, and the logical address
assigned to Unregistered devices is also 0xf and the logic didn't handle
that correctly.

usb: fixes for v4.8-rc6
Unfortunately we have a bogus dwc3 patch leaked through the cracks and
got merged into Linus' HEAD. That patch ended up causing off-by-1 error
in our TRB accounting logic. Thankfully John Youn found out the problem
and we provided a revert to the bogus dwc3 patch in no time.
Apart from this off-by-1 error, we have two fixes to the Renesas drivers,
a small fix to our generic phy driver, a NULL pointer dereference fix for
f_eem and a build warning fix in dwc3.

carl9170_usb_stop() is used from several places to flush and cleanup any
pending work. The normal pattern is to send a request and wait for the
irq handler to call complete(). The completion is not reinitialized
during normal operation and as the old comment indicates it is important
to keep calls to wait_for_completion_timeout() and complete() balanced.
Calling complete_all() brings this equilibirum out of balance and needs
to be fixed by a reinit_completion(). But that opens a small race
window. It is possible that the sequence of complete_all(),
reinit_completion() is faster than the wait_for_completion_timeout() can
do its work. The wake up is not lost but the done counter test is after
reinit_completion() has been executed. The only reason we don't see
carl9170_exec_cmd() hang forever is we use the timeout version of
wait_for_copletion().
Let's fix this by reinitializing the completion (that is just setting
done counter to 0) just before we send out an request. Now,
carl9170_usb_stop() can be sure a complete() call is enough to make
progess since there is only one waiter at max. This is a common pattern
also seen in various drivers which use completion.

The ath6kl driver attempts to get the txpower value from the radio by first
clearing the existing stored value and then watching the value to become
non-zero.
APs allow setting client power to values from -127..127, but this radio
is not capable of setting values less then 0 and so will report txpower
as 0dbm for both negative and 0 client power values.
When the radio has txpower set to 0dbm txpower (equivalent to 1mw) the
ath6kl_cfg80211_get_txpower() function will remain in the
wait_event_interruptible_timeout() loop waiting for the value to be
non-zero, and will eventually timeout. This results in a 5 second delay in
response. However, the correct value of zero is eventually returned.
The 6004 defaults to 63dbm which is then limited by regulatory and
hardware limits with max of 18dbm (6003 max is 16dbm), therefore we can
use values larger then these to be able to determine when the value has
been updated.
To correct the issue, set the value to a nonsensical value (255) and wait
for it to change to the valid value.
Tested on both 6003 and 6004 based radios. Return value of zero is
correctly returned in an expected amount of time (similar to when
returning non-zero values) when AP client power is set to both 0 and
negative values.

The firmware crash dumps on the 6004 are the same as the 6003. Remove the
statement guarding it from dumping on the 6004. Renamed the
REG_DUMP_COUNT_AR6003 to reflect support on both chips.
