Below commit missed the AF_IB and loopback code flow in
rdma_resolve_addr(). This leads to an unbalanced cm_id refcount in
cma_work_handler() which puts the refcount which was not incremented prior
to queuing the work.
A call trace is observed with such code flow:
BUG: unable to handle kernel NULL pointer dereference at (null)
[<ffffffff96b67e16>] __mutex_lock_slowpath+0x166/0x1d0
[<ffffffff96b6715f>] mutex_lock+0x1f/0x2f

Hence, hold the cm_id reference when scheduling the resolve work item.

In the HID++ 2.0 function getBatteryInfo() from the BatteryVoltage
(0x1001) feature, chargeStatus is only valid if extPower is active.
Previously we were ignoring extPower, which resulted in wrong values.
Example:
With an unplugged mouse
$ cat /sys/class/power_supply/hidpp_battery_0/status

This patch fixes that, it also renames charge_sts to flags as
charge_sts can be confused with chargeStatus from the spec.

There's an OF helper called of_dma_is_coherent(), which checks if a
device has a "dma-coherent" property to see if the device is coherent
for DMA.
But on some platforms devices are coherent by default, and on some
platforms it's not possible to update existing device trees to add the
"dma-coherent" property.
So add a Kconfig symbol to allow arch code to tell
of_dma_is_coherent() that devices are coherent by default, regardless
of the presence of the property.
Select that symbol on powerpc when NOT_COHERENT_CACHE is not set, ie.
when the system has a coherent cache.

This adds MSI support to the Broadcom STB PCIe host controller. The MSI
controller is physically located within the PCIe block, however, there
is no reason why the MSI controller could not be moved elsewhere in the
future. MSIX is not supported by the HW.
Since the internal Brcmstb MSI controller is intertwined with the PCIe
controller, it is not its own platform device but rather part of the
PCIe platform device.

We currently allocate redistributor region structures for
individual redistributors when ACPI doesn't present us with
compact MMIO regions covering multiple redistributors.
It turns out that we allocate these structures even when
the redistributor is flagged as disabled by ACPI. It works
fine until someone actually tries to tarse one of these
structures, and access the corresponding MMIO region.
Instead, track the number of enabled redistributors, and
only allocate what is required. This makes sure that there
is no invalid data to misuse.

Pull irq updates from Thomas Gleixner:
"The interrupt departement provides:
- A mechanism to shield isolated tasks from managed interrupts:
The affinity of managed interrupts is completely controlled by the
kernel and user space has no influence on them. The reason is that
the automatically assigned affinity correlates to the multi-queue
CPU handling of block devices.
If the generated affinity mask spaws both housekeeping and isolated
CPUs the interrupt could be routed to an isolated CPU which would
then be disturbed by I/O submitted by a housekeeping CPU.
The new mechamism ensures that as long as one housekeeping CPU is
online in the assigned affinity mask the interrupt is routed to a
housekeeping CPU.
If there is no online housekeeping CPU in the affinity mask, then
the interrupt is routed to an isolated CPU to keep the device queue
intact, but unless the isolated CPU submits I/O by itself these
interrupts are not raised.
- A small addon to the device tree irqdomain core code to avoid
duplication in irq chip drivers
- Conversion of the SiFive PLIC to hierarchical domains

Pull timer updates from Thomas Gleixner:
"The timekeeping and timers departement provides:
- Time namespace support:
If a container migrates from one host to another then it expects
that clocks based on MONOTONIC and BOOTTIME are not subject to
disruption. Due to different boot time and non-suspended runtime
these clocks can differ significantly on two hosts, in the worst
case time goes backwards which is a violation of the POSIX
requirements.
The time namespace addresses this problem. It allows to set offsets
for clock MONOTONIC and BOOTTIME once after creation and before
tasks are associated with the namespace. These offsets are taken
into account by timers and timekeeping including the VDSO.
Offsets for wall clock based clocks (REALTIME/TAI) are not provided
by this mechanism. While in theory possible, the overhead and code
complexity would be immense and not justified by the esoteric
potential use cases which were discussed at Plumbers '18.
The overhead for tasks in the root namespace (ie where host time
offsets = 0) is in the noise and great effort was made to ensure
that especially in the VDSO. If time namespace is disabled in the
kernel configuration the code is compiled out.
Kudos to Andrei Vagin and Dmitry Sofanov who implemented this
feature and kept on for more than a year addressing review
comments, finding better solutions. A pleasant experience.

that the init/suspend/resume ordering is correct.

Merely enabling I2C and RTC selects REGMAP_I2C and REGMAP_SPI, even when
no driver needs it. While the former can be moduler, the latter cannot,
and thus becomes built-in.
Fix this by moving the select statements for REGMAP_I2C and REGMAP_SPI
from the RTC_I2C_AND_SPI helper to the individual drivers that depend on
it.
Note that the comment for RTC_I2C_AND_SPI refers to SND_SOC_I2C_AND_SPI
for more information, but the latter does not select REGMAP_{I2C,SPI}
itself, and defers that to the individual drivers, too.

[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.
A year ago this was partly remedied with:
commit 80adaebd2d41 ("drm/amd/display: Don't skip link training for empty dongle")
This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).
This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.
In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.
[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.
With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd2d41 ("drm/amd/display: Don't skip link training for empty dongle")
Fixes: 0301ccbaf67d ("drm/amd/display: DP Compliance 400.1.1 failure")

Using CX-3 virtual functions, either from a bare-metal machine or
pass-through from a VM, MAD packets are proxied through the PF driver.
Since the VF drivers have separate name spaces for MAD Transaction Ids
(TIDs), the PF driver has to re-map the TIDs and keep the book keeping in
a cache.
Following the RDMA Connection Manager (CM) protocol, it is clear when an
entry has to evicted from the cache. When a DREP is sent from
mlx4_ib_multiplex_cm_handler(), id_map_find_del() is called. Similar when
a REJ is received by the mlx4_ib_demux_cm_handler(), id_map_find_del() is
called.
This function wipes out the TID in use from the IDR or XArray and removes
the id_map_entry from the table.
In short, it does everything except the topping of the cake, which is to
remove the entry from the list and free it. In other words, for the REJ
case enumerated above, one id_map_entry will be leaked.
For the other case above, a DREQ has been received first. The reception of
the DREQ will trigger queuing of a delayed work to delete the
id_map_entry, for the case where the VM doesn't send back a DREP.
In the normal case, the VM _will_ send back a DREP, and id_map_find_del()
will be called.
But this scenario introduces a secondary leak. First, when the DREQ is
received, a delayed work is queued. The VM will then return a DREP, which
will call id_map_find_del(). As stated above, this will free the TID used
from the XArray or IDR. Now, there is window where that particular TID can
be re-allocated, lets say by an outgoing REQ. This TID will later be wiped
out by the delayed work, when the function id_map_ent_timeout() is
called. But the id_map_entry allocated by the outgoing REQ will not be
de-allocated, and we have a leak.
Both leaks are fixed by removing the id_map_find_del() function and only
using schedule_delayed(). Of course, a check in schedule_delayed() to see
if the work already has been queued, has been added.
Another benefit of always using the delayed version for deleting entries,
is that we do get a TimeWait effect; a TID no longer in use, will occupy
the XArray or IDR for CM_CLEANUP_CACHE_TIMEOUT time, without any ability
of being re-used for that time period.
