Linus Torvalds 0bae60fcee There are two major achievements for MMC in this release, which deserves to be
specially highlighted.
 
 First, we have converted the MMC block device from using the legacy blk
 interface into using the modern blkmq interface. Not only do we get all the
 nice effects from using blkmq, but it also means that new fresh nice code
 replaces old rusty code. Great news to everybody that cares about MMC/SD!
 
 It should also be noted that converting to blkmq has not been trivial, mostly
 because of that we have been carrying too much of MMC specific optimizations
 for the I/O request path, rather than striving to move these to the generic blk
 layer. Hopefully we won't be doing that mistake, ever again.
 
 Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both
 have been working on this for quite some time!
 
 Second, on top of the blkmq deployment, we have enabled full support the eMMC
 command queuing feature, introduced in the eMMC v.5.1 spec. This also includes
 an implementation of a host driver library, supporting the corresponding CQHCI
 HW. Ideally, those controllers that supports CQHCI should only need some minor
 adaptations to make this play.
 
 So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver
 used on Rockchip RK3399, have enabled support for eMMC command queueing.
 
 Worth to highlight is also that, implementing the eMMC command queuing support
 has been a collaborative effort, as several people from Codeaurora, Rockchip,
 Intel and Linaro have been involved. However, the work has been driven by
 Adrian Hunter (Intel).
 
 In some shadow of the above, here are the rest of the highlights:
 
 MMC core:
  - Don't remove non-removable cards during system suspend
  - Add a slot-gpio helper to check capability of GPIO WP detection
 
 MMC host:
  - sdhci: Cleanups and improvements of some wakeup related code
  - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
  - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
  - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
  - sdhci_f_sdh30: Add ACPI support
  - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
  - sdhci-of-esdhc: A few minor fixes
  - mmci: Add support for new STM32 variant
  - renesas_sdhi: enable R-Car D3 (r8a77995) support
  - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations

Eric Dumazet e64e469b9a ipv6: addrconf: break critical section in addrconf_verify_rtnl()
Heiner reported a lockdep splat [1]

This is caused by attempting GFP_KERNEL allocation while RCU lock is
held and BH blocked.

We believe that addrconf_verify_rtnl() could run for a long period,
so instead of using GFP_ATOMIC here as Ido suggested, we should break
the critical section and restart it after the allocation.

Wei Wang 31afeb425f ipv6: change route cache aging logic
In current route cache aging logic, if a route has both RTF_EXPIRE and
RTF_GATEWAY set, the route will only be removed if the neighbor cache
has no NTF_ROUTER flag. Otherwise, even if the route has expired, it
won't get deleted.
Fix this logic to always check if the route has expired first and then
do the gateway neighbor cache check if previous check decide to not
remove the exception entry.

When compared to ixgbe and other previous Intel drivers the i40e and i40evf
drivers actually reserve 2 additional descriptors in maybe_stop_tx for
cache line alignment. We need to update DESC_NEEDED to reflect this as
otherwise we are more likely to return TX_BUSY which will cause issues with

Andy Spencer 202a0a70e4 gianfar: prevent integer wrapping in the rx handler
When the frame check sequence (FCS) is split across the last two frames
of a fragmented packet, part of the FCS gets counted twice, once when
subtracting the FCS, and again when subtracting the previously received
data.

For example, if 1602 bytes are received, and the first fragment contains
the first 1600 bytes (including the first two bytes of the FCS), and the
second fragment contains the last two bytes of the FCS:

  'skb->len == 1600' from the first fragment

Khazhismel Kumykov f20426056f dm mpath selector: more evenly distribute ties
Move the last used path to the end of the list (least preferred) so that
ties are more evenly distributed.

For example, in case with three paths with one that is slower than
others, the remaining two would be unevenly used if they tie. This is
due to the rotation not being a truely fair distribution.

Illustrated: paths a, b, c, 'c' has 1 outstanding IO, a and b are 'tied'
Three possible rotations:
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
...

So 'a' is used 2x more than 'b', although they should be used evenly.

With this change, the most recently used path is always the least
preferred, removing this bias resulting in even distribution.
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
(c, b, a) -> best path 'b'

Scott Bauer cc65661981 dm unstripe: fix target length versus number of stripes size check
Since the unstripe target takes a target length which is the
size of *one* striped member we're trying to expose, not the
total size of *all* the striped members, the check does not
make sense and fails for some striped setups.

For example, say we have a 4TB striped device:
or 3907018496 sectors per underlying device:

if (sector_div(width, uc->stripes)) :
   3907018496 / 2(num stripes)  == 1953509248

tmp_len = width;
if (sector_div(tmp_len, uc->chunk_size)) :
   1953509248 / 256(chunk size) == 7630895.5
   (fails)

Fix this by removing the first check which isn't valid for unstriping.

Mike Snitzer eaa160eded dm table: fix NVMe bio-based dm_table_determine_type() validation
The 'verify_rq_based:' code in dm_table_determine_type() was checking
all devices in the DM table rather than only checking the data devices.
Fix this by using the immutable target's iterate_devices method.

Also, tweak the block of dm_table_determine_type() code that decides
whether to upgrade from DM_TYPE_BIO_BASED to DM_TYPE_NVME_BIO_BASED so
that it makes sure the immutable_target doesn't support require
splitting IOs.

These changes have been verified to allow a "thin-pool" target whose
data device is an NVMe device to be upgraded to DM_TYPE_NVME_BIO_BASED.
Using the thin-pool in NVMe bio-based mode was verified to pass all the
device-mapper-test-suite's "thin-provisioning" tests.

Also verified that request-based DM multipath (with queue_mode "rq" and
"mq") works as expected using the 'mptest' harness.

Mike Snitzer ac514ffc96 dm mpath: delay the retry of a request if the target responded as busy
Add DM_ENDIO_DELAY_REQUEUE to allow request-based multipath's
multipath_end_io() to instruct dm-rq.c:dm_done() to delay a requeue.
This is beneficial to do if BLK_STS_RESOURCE is returned from the target
(because target is busy).

Relative to blk-mq: kick the hw queues via blk_mq_requeue_work(),
indirectly from dm-rq.c:__dm_mq_kick_requeue_list(), after a delay.

For old .request_fn: use blk_delay_queue().

bio-based multipath doesn't have feature parity with request-based for
retryable error requeues; that is something that'll need fixing in the
future.

Pull power management updates from Rafael Wysocki:
 "This includes some infrastructure changes in the PM core, mostly
  related to integration between runtime PM and system-wide suspend and
  hibernation, plus some driver changes depending on them and fixes for
  issues in that area which have become quite apparent recently.

  Also included are changes making more x86-based systems use the Low
  Power Sleep S0 _DSM interface by default, which turned out to be
  necessary to handle power button wakeups from suspend-to-idle on
  Surface Pro3.

  On the cpufreq front we have fixes and cleanups in the core, some new
  hardware support, driver updates and the removal of some unused code
  from the CPU cooling thermal driver.

  Apart from this, the Operating Performance Points (OPP) framework is
  prepared to be used with power domains in the future and there is a
  usual bunch of assorted fixes and cleanups.

Cong Wang says:

====================
net_sched: reflect tx_queue_len change for pfifo_fast

This pathcset restores the pfifo_fast qdisc behavior of dropping
packets based on latest dev->tx_queue_len. Patch 1 introduces
a helper, patch 2 introduces a new Qdisc ops which is called when
we modify tx_queue_len, patch 3 implements this ops for pfifo_fast.

Please see each patch for details.

Cong Wang 7007ba630e net_sched: implement ->change_tx_queue_len() for pfifo_fast
pfifo_fast used to drop based on qdisc_dev(qdisc)->tx_queue_len,
so we have to resize skb array when we change tx_queue_len.

Other qdiscs which read tx_queue_len are fine because they
all save it to sch->limit or somewhere else in qdisc during init.
They don't have to implement this, it is nicer if they do so
that users don't have to re-configure qdisc after changing
tx_queue_len.

Cong Wang 48bfd55e7e net_sched: plug in qdisc ops change_tx_queue_len
Introduce a new qdisc ops ->change_tx_queue_len() so that
each qdisc could decide how to implement this if it wants.
Previously we simply read dev->tx_queue_len, after pfifo_fast
switches to skb array, we need this API to resize the skb array
when we change dev->tx_queue_len.

To avoid handling race conditions with TX BH, we need to
deactivate all TX queues before change the value and bring them
back after we are done, this also makes implementation easier.

This patch promotes the local change_tx_queue_len() to a core
helper function, dev_change_tx_queue_len(), so that rtnetlink
and net-sysfs could share the code. This also prepares for the
following patch.

Note, the -EFAULT in the original code doesn't make sense,
we should propagate the errno from notifiers.

Linus Torvalds 1c1f395b28 sound updates for 4.16-rc1
The major changes in the core API side in this cycle are the still
 on-going ASoC componentization works.  Other than that, only few small
 changes such as 20bit PCM format support are found.
 
 Meanwhile the rest majority of changes are for ASoC drivers:
 - Large cleanups of some of the TI CODEC drivers
 - Continued work on Intel ASoC stuff for new quirks, ACPI GPIO
   handling, Kconfigs and lots of cleanups
 - Refactoring of the Freescale SSI driver, as preliminary work for the
   upcoming changes
 - Work on ST DFSDM driver, including the required IIO patches
 - New drivers for Allwinner A83T, Maxim MAX89373, SocioNext UiniPhier
   EVEA Tempo Semiconductor TSCS42xx and TI PCM816x, TAS5722 and TAS6424
   devices
 - Removal of dead codes for SN95031 and board drivers
 
 Last but not least, a few HD-audio and USB-audio quirks are included
 as usual, too.

Pull sound updates from Takashi Iwai:
 "The major changes in the core API side in this cycle are the still
  on-going ASoC componentization works. Other than that, only few small
  changes such as 20bit PCM format support are found.

  Meanwhile the rest majority of changes are for ASoC drivers:

   - Large cleanups of some of the TI CODEC drivers

   - Continued work on Intel ASoC stuff for new quirks, ACPI GPIO
     handling, Kconfigs and lots of cleanups

   - Refactoring of the Freescale SSI driver, as preliminary work for
     the upcoming changes

   - Work on ST DFSDM driver, including the required IIO patches

   - New drivers for Allwinner A83T, Maxim MAX89373, SocioNext UiniPhier
     EVEA Tempo Semiconductor TSCS42xx and TI PCM816x, TAS5722 and
     TAS6424 devices

   - Removal of dead codes for SN95031 and board drivers

  Last but not least, a few HD-audio and USB-audio quirks are included
  as usual, too"

Vadim Lomovtsev 6b9e65474b net: ethernet: cavium: Correct Cavium Thunderx NIC driver names accordingly to module name
It was found that ethtool provides unexisting module name while
it queries the specified network device for associated driver
information. Then user tries to unload that module by provided
module name and fails.

This happens because ethtool reads value of DRV_NAME macro,
while module name is defined at the driver's Makefile.

This patch is to correct Cavium CN88xx Thunder NIC driver names
(DRV_NAME macro) 'thunder-nicvf' to 'nicvf' and 'thunder-nic'
to 'nicpf', sync bgx and xcv driver names accordingly to their
module names.

Pull init_task initializer cleanups from David Howells:
 "It doesn't seem useful to have the init_task in a header file rather
  than in a normal source file. We could consolidate init_task handling
  instead and expand out various macros.

  Here's a series of patches that consolidate init_task handling:

   (1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and
       openrisc.

   (2) Alter the INIT_TASK_DATA linker script macro to set
       init_thread_union and init_stack rather than defining these in C.

       Insert init_task and init_thread_into into the init_stack area in
       the linker script as appropriate to the configuration, with
       different section markers so that they end up correctly ordered.

       We can then get merge ia64's init_task.c into the main one.

       We then have a bunch of single-use INIT_*() macros that seem only
       to be macros because they used to be used per-arch. We can then
       expand these in place of the user and get rid of a few lines and
       a lot of backslashes.

   (3) Expand INIT_TASK() in place.

   (4) Expand in place various small INIT_*() macros that are defined
       conditionally. Expand them and surround them by #if[n]def/#endif
       in the .c file as it takes fewer lines.

   (5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place.

   (6) Expand INIT_STRUCT_PID in place.

  These macros can then be discarded"

do so results in: kernel BUG at fs/gfs2/trans.c:117!

Martin KaFai Lau 7ece54a60e ipv6: Fix SO_REUSEPORT UDP socket with implicit sk_ipv6only
If a sk_v6_rcv_saddr is !IPV6_ADDR_ANY and !IPV6_ADDR_MAPPED, it
implicitly implies it is an ipv6only socket.  However, in inet6_bind(),
this addr_type checking and setting sk->sk_ipv6only to 1 are only done
after sk->sk_prot->get_port(sk, snum) has been completed successfully.

This inconsistency between sk_v6_rcv_saddr and sk_ipv6only confuses
the 'get_port()'.

In particular, when binding SO_REUSEPORT UDP sockets,
udp_reuseport_add_sock(sk,...) is called.  udp_reuseport_add_sock()
checks "ipv6_only_sock(sk2) == ipv6_only_sock(sk)" before adding sk to
sk2->sk_reuseport_cb.  In this case, ipv6_only_sock(sk2) could be
1 while ipv6_only_sock(sk) is still 0 here.  The end result is,
reuseport_alloc(sk) is called instead of adding sk to the existing
sk2->sk_reuseport_cb.

It can be reproduced by binding two SO_REUSEPORT UDP sockets on an
IPv6 address (!ANY and !MAPPED).  Only one of the socket will
receive packet.

The fix is to set the implicit sk_ipv6only before calling get_port().
The original sk_ipv6only has to be saved such that it can be restored
in case get_port() failed.  The situation is similar to the
inet_reset_saddr(sk) after get_port() has failed.

Thanks to Calvin Owens <calvinowens@fb.com> who created an easy
reproduction which leads to a fix.
