[ Upstream commit 2f3f7d1fa0d1039b24a55d127ed190f196fc3e79 ]
If you configure a route with multiple labels, e.g.
ip route add 10.10.3.0/24 encap mpls 16/100 via 10.10.2.2 dev ens4
A warning is logged:
kernel: [ 130.561819] netlink: 'ip': attribute type 1 has an invalid
length.
This happens because mpls_iptunnel_policy has set the type of
MPLS_IPTUNNEL_DST to fixed size NLA_U32.
Change it to a minimum size.
nla_get_labels() does the remaining validation.

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.

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.

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.

This is incorrect. Existing parent device should not be touched.

In the function mmc_alloc_host, the function put_device is called to
release allocated resources when mmc_gpio_alloc fails. Finally, the
function pointed by host->class_dev.class->dev_release (i.e.,
mmc_host_classdev_release) is used to release resources including the
host structure. However, after put_device, host is used and released
again. Resulting in a use-after-free bug.

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.

The kernel parameter igfx_off is used by users to disable
DMA remapping for the Intel integrated graphic device. It
was designed for bare metal cases where a dedicated IOMMU
is used for graphic. This doesn't apply to virtual IOMMU
case where an include-all IOMMU is used. This makes the
kernel parameter work with virtual IOMMU as well.

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.
