61d7f6a117 ASoC: ti: davinci-mcasp: Fix slot mask settings when using multiple AXRs
[ Upstream commit fd14f4436fd47d5418023c90e933e66d3645552e ]

If multiple serializers are connected in the system and the number of
channels will need to use more than one serializer the mask to enable the
serializers were left to 0 if tdm_mask is provided

d7ae1636c8 net/af_iucv: always register net_device notifier
[ Upstream commit 06996c1d4088a0d5f3e7789d7f96b4653cc947cc ]

Even when running as VM guest (ie pr_iucv != NULL), af_iucv can still
open HiperTransport-based connections. For robust operation these
connections require the af_iucv_netdev_notifier, so register it
unconditionally.

594c7921a5 net: netem: fix backlog accounting for corrupted GSO frames
[ Upstream commit 177b8007463c4f36c9a2c7ce7aa9875a4cad9bd5 ]

When GSO frame has to be corrupted netem uses skb_gso_segment()
to produce the list of frames, and re-enqueues the segments one
by one.  The backlog length has to be adjusted to account for
new frames.

The current calculation is incorrect, leading to wrong backlog
lengths in the parent qdisc (both bytes and packets), and
incorrect packet backlog count in netem itself.

Parent backlog goes negative, netem's packet backlog counts
all non-first segments twice (thus remaining non-zero even
after qdisc is emptied).

Move the variables used to count the adjustment into local
scope to make 100% sure they aren't used at any stage in
backports.

8ae8a9f21e inet: frags: call inet_frags_fini() after unregister_pernet_subsys()
[ Upstream commit ae7352d384a552d8c799c242e74a934809990a71 ]

Both IPv6 and 6lowpan are calling inet_frags_fini() too soon.

inet_frags_fini() is dismantling a kmem_cache, that might be needed
later when unregister_pernet_subsys() eventually has to remove
frags queues from hash tables and free them.

This fixes potential use-after-free, and is a prereq for the following patch.

e038a1b626 signal/cifs: Fix cifs_put_tcp_session to call send_sig instead of force_sig
[ Upstream commit 72abe3bcf0911d69b46c1e8bdb5612675e0ac42c ]

The locking in force_sig_info is not prepared to deal with a task that
exits or execs (as sighand may change).  The is not a locking problem
in force_sig as force_sig is only built to handle synchronous
exceptions.

Further the function force_sig_info changes the signal state if the
signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the
delivery of the signal.  The signal SIGKILL can not be ignored and can
not be blocked and SIGNAL_UNKILLABLE won't prevent it from being
delivered.

So using force_sig rather than send_sig for SIGKILL is confusing
and pointless.

Because it won't impact the sending of the signal and and because
using force_sig is wrong, replace force_sig with send_sig.

ccd9708c9c misc: sgi-xp: Properly initialize buf in xpc_get_rsvd_page_pa
[ Upstream commit b0576f9ecb5c51e9932531d23c447b2739261841 ]

Clang warns:

drivers/misc/sgi-xp/xpc_partition.c:73:14: warning: variable 'buf' is
uninitialized when used within its own initialization [-Wuninitialized]
        void *buf = buf;
              ~~~   ^~~
1 warning generated.

Arnd's explanation during review:

  /*
   * Returns the physical address of the partition's reserved page through
   * an iterative number of calls.
   *
   * On first call, 'cookie' and 'len' should be set to 0, and 'addr'
   * set to the nasid of the partition whose reserved page's address is
   * being sought.
   * On subsequent calls, pass the values, that were passed back on the
   * previous call.
   *
   * While the return status equals SALRET_MORE_PASSES, keep calling
   * this function after first copying 'len' bytes starting at 'addr'
   * into 'buf'. Once the return status equals SALRET_OK, 'addr' will
   * be the physical address of the partition's reserved page. If the
   * return status equals neither of these, an error as occurred.
   */
  static inline s64
  sn_partition_reserved_page_pa(u64 buf, u64 *cookie, u64 *addr, u64 *len)

  so *len is set to zero on the first call and tells the bios how many
  bytes are accessible at 'buf', and it does get updated by the BIOS to
  tell us how many bytes it needs, and then we allocate that and try again.

b14cc6e9dd dmaengine: tegra210-adma: Fix crash during probe
[ Upstream commit b53611fb1ce9b1786bd18205473e0c1d6bfa8934 ]

Commit f33e7bb3eb92 ("dmaengine: tegra210-adma: restore channel status")
added support to save and restore the DMA channel registers when runtime
suspending the ADMA. This change is causing the kernel to crash when
probing the ADMA, if the device is probed deferred when looking up the
channel interrupts. The crash occurs because not all of the channel base
addresses have been setup at this point and in the clean-up path of the
probe, pm_runtime_suspend() is called invoking its callback which
expects all the channel base addresses to be initialised.

Although this could be fixed by simply checking for a NULL address, on
further review of the driver it seems more appropriate that we only call
pm_runtime_get_sync() after all the channel interrupts and base
addresses have been configured. Therefore, fix this crash by moving the
calls to pm_runtime_enable(), pm_runtime_get_sync() and
tegra_adma_init() after the DMA channels have been initialised.

56fc3de955 thermal: cpu_cooling: Actually trace CPU load in thermal_power_cpu_get_power
[ Upstream commit bf45ac18b78038e43af3c1a273cae4ab5704d2ce ]

The CPU load values passed to the thermal_power_cpu_get_power
tracepoint are zero for all CPUs, unless, unless the
thermal_power_cpu_limit tracepoint is enabled too:

  irq/41-rockchip-98    [000] ....   290.972410: thermal_power_cpu_get_power:
  cpus=0000000f freq=1800000 load={{0x0,0x0,0x0,0x0}} dynamic_power=4815

vs

  irq/41-rockchip-96    [000] ....    95.773585: thermal_power_cpu_get_power:
  cpus=0000000f freq=1800000 load={{0x56,0x64,0x64,0x5e}} dynamic_power=4959
  irq/41-rockchip-96    [000] ....    95.773596: thermal_power_cpu_limit:
  cpus=0000000f freq=408000 cdev_state=10 power=416

There seems to be no good reason for omitting the CPU load information
depending on another tracepoint. My guess is that the intention was to
check whether thermal_power_cpu_get_power is (still) enabled, however
'load_cpu != NULL' already indicates that it was at least enabled when
cpufreq_get_requested_power() was entered, there seems little gain
from omitting the assignment if the tracepoint was just disabled, so
just remove the check.

want.

[ Upstream commit f33e7bb3eb922618612a90f0a828c790e8880773 ]

Status of ADMA channel registers is not saved and restored during system
suspend. During active playback if system enters suspend, this results in
wrong state of channel registers during system resume and playback fails
to resume properly. Fix this by saving following channel registers in
runtime suspend and restore during runtime resume.
 * ADMA_CH_LOWER_SRC_ADDR
 * ADMA_CH_LOWER_TRG_ADDR
 * ADMA_CH_FIFO_CTRL
 * ADMA_CH_CONFIG
 * ADMA_CH_CTRL
 * ADMA_CH_CMD
 * ADMA_CH_TC
Runtime PM calls will be inovked during system resume path if a playback
or capture needs to be resumed. Hence above changes work fine for system
suspend case.

db97aff1d9 IB/mlx5: Add missing XRC options to QP optional params mask
[ Upstream commit 8f4426aa19fcdb9326ac44154a117b1a3a5ae126 ]

The QP transition optional parameters for the various transition for XRC
QPs are identical to those for RC QPs.

Many of the XRC QP transition optional parameter bits are missing from the
QP optional mask table.  These omissions caused failures when doing XRC QP
state transitions.

For example, when trying to change the response timer of an XRC receive QP
via the RTS2RTS transition, the new timer value was ignored because
MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
for XRC qps for the RTS2RTS transition.

Fix this by adding the missing XRC optional parameters for all QP
transitions to the opt_mask table.

Packet send checks that msg_name is at least sizeof sockaddr_ll.
Packet recv must return at least this length, so that its output
can be passed unmodified to packet send.

This ceased to be true since adding support for lladdr longer than
sll_addr. Since, the return value uses true address length.

Always return at least sizeof sockaddr_ll, even if address length
is shorter. Zero the padding bytes.

Change v1->v2: do not overwrite zeroed padding again. use copy_len.

9d12b9afe3 dmaengine: axi-dmac: Don't check the number of frames for alignment
[ Upstream commit 648865a79d8ee3d1aa64aab5eb2a9d12eeed14f9 ]

In 2D transfers (for the AXI DMAC), the number of frames (numf) represents
Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful
for video transfers where screen resolutions ( X * Y ) are typically
aligned for X, but not for Y.

There is no requirement for Y_LENGTH to be aligned to the bus-width (or
anything), and this is also true for AXI DMAC.

Checking the Y_LENGTH for alignment causes false errors when initiating DMA
transfers. This change fixes this by checking only that the Y_LENGTH is
non-zero.

b41e07cf97 ARM: dts: ls1021: Fix SGMII PCS link remaining down after PHY disconnect
[ Upstream commit c7861adbe37f576931650ad8ef805e0c47564b9a ]

Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus.
But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC
are pointing towards the same internal PCS. Therefore nobody is
controlling the internal PCS of eTSEC0.

Upon initial ndo_open, the SGMII link is ok by virtue of U-boot
initialization. But upon an ifdown/ifup sequence, the code path from
ndo_open -> init_phy -> gfar_configure_serdes does not get executed for
the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII
link remains down for eTSEC0. On the LS1021A-TWR board, to signal this
failure condition, the PHY driver keeps printing
'803x_aneg_done: SGMII link is not ok'.

Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match
mdio1 device.

e75d6d178f spi: bcm2835aux: fix driver to not allow 65535 (=-1) cs-gpios
[ Upstream commit 509c583620e9053e43d611bf1614fc3d3abafa96 ]

The original driver by default defines num_chipselects as -1.
This actually allicates an array of 65535 entries in
of_spi_register_master.

There is a side-effect for buggy device trees that (contrary to
dt-binding documentation) have no cs-gpio defined.

This mode was never supported by the driver due to limitations
of native cs and additional code complexity and is explicitly
not stated to be implemented.

To keep backwards compatibility with such buggy DTs we limit
the number of chip_selects to 1, as for all practical purposes
it is only ever realistic to use a single chip select in
native cs mode without negative side-effects.

175c0e883b spi: tegra114: fix for unpacked mode transfers
[ Upstream commit 1a89ac5b91895127f7c586ec5075c3753ca25501 ]

Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked
mode when transfer length is not a multiple of requested bits per word.

unpacked mode transfers fails when the transfer includes partial bytes in
the last word.

Total words to be written/read to/from FIFO is computed based on transfer
length and bits per word. Unpacked mode includes 0 padding bytes for partial
words to align with bits per word and these extra bytes are also accounted
for calculating bytes left to transfer in the current driver.

This causes extra bytes access of tx/rx buffers along with buffer index
position crossing actual length where remain_len becomes negative and due to
unsigned type, negative value is a 32 bit representation of signed value
and transferred bytes never meets the actual transfer length resulting in
transfer timeout and a hang.

This patch fixes this with proper computation of the actual bytes to fill in
FIFO during transmit and the actual bytes to read from FIFO during receive
ignoring 0 padded bytes.

[ Upstream commit 7b3d10cdf54b8bc1dc0da21faed9789ac4da3684 ]

Fixes: Clear packed bit when not using packed mode.

Packed bit is not cleared when not using packed mode. This results
in transfer timeouts for the unpacked mode transfers followed by the
packed mode transfers.
