iwlwifi: dbg: don't crash if the firmware crashes in the middle of a debug dump

[ Upstream commit 79f25b10c9da3dbc953e47033d0494e51580ac3b ]

We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.

When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.

We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.

To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

PCI/ERR: Run error recovery callbacks for all affected devices

[ Upstream commit bfcb79fca19d267712e425af1dd48812c40dec0c ]

If an Endpoint reported an error with ERR_FATAL, we previously ran driver
error recovery callbacks only for the Endpoint's driver.  But if we reset a
Link to recover from the error, all downstream components are affected,
including the Endpoint, any multi-function peers, and children of those
peers.

Initiate the Link reset from the deepest Downstream Port that is
reliable, and call the error recovery callbacks for all its children.

If a Downstream Port (including a Root Port) reports an error, we assume
the Port itself is reliable and we need to reset its downstream Link.  In
all other cases (Switch Upstream Ports, Endpoints, Bridges, etc), we assume
the Link leading to the component needs to be reset, so we initiate the
reset at the parent Downstream Port.

This allows two other clean-ups.  First, we currently only use a Link
reset, which can only be initiated using a Downstream Port, so we can
remove checks for Endpoints.  Second, the Downstream Port where we initiate
the Link reset is reliable (unlike components downstream from it), so the
special cases for error detect and resume are no longer necessary.

coresight: dynamic-replicator: Handle multiple connections

[ Upstream commit 30af4fb619e5126cb3152072e687b377fc9398d6 ]

When a replicator port is enabled, we block the traffic
on the other port and route all traffic to the new enabled
port. If there are two active trace sessions each targeting
the two different paths from the replicator, the second session
will disable the first session and route all the data to the
second path.
                    ETR
                 /
e.g, replicator
                 \
                    ETB

If CPU0 is operated in sysfs mode to ETR and CPU1 is operated
in perf mode to ETB, depending on the order in which the
replicator is enabled one device is blocked.

Ideally we need trace-id for the session to make the
right choice. That implies we need a trace-id allocation
logic for the coresight subsystem and use that to route
the traffic. The short term solution is to only manage
the "target port" and leave the other port untouched.
That leaves both the paths unaffected, except that some
unwanted traffic may be pushed to the paths (if the Trace-IDs
are not far enough), which is still fine and can be filtered
out while processing rather than silently blocking the data.

coresight: tmc-etr: Handle driver mode specific ETR buffers

[ Upstream commit 96a7f644006ecc05eaaa1a5d09373d0ee63beb0a ]

Since the ETR could be driven either by SYSFS or by perf, it
becomes complicated how we deal with the buffers used for each
of these modes. The ETR driver cannot simply free the current
attached buffer without knowing the provider (i.e, sysfs vs perf).

To solve this issue, we provide:
1) the driver-mode specific etr buffer to be retained in the drvdata
2) the etr_buf for a session should be passed on when enabling the
   hardware, which will be stored in drvdata->etr_buf. This will be
   replaced (not free'd) as soon as the hardware is disabled, after
   necessary sync operation.

The advantages of this are :

1) The common code path doesn't need to worry about how to dispose
   an existing buffer, if it is about to start a new session with a
   different buffer, possibly in a different mode.
2) The driver mode can control its buffers and can get access to the
   saved session even when the hardware is operating in a different
   mode. (e.g, we can still access a trace buffer from a sysfs mode
   even if the etr is now used in perf mode, without disrupting the
   current session.)

Towards this, we introduce a sysfs specific data which will hold the
etr_buf used for sysfs mode of operation, controlled solely by the
sysfs mode handling code.

coresight: Fix handling of sinks

[ Upstream commit c71369de02b285d9da526a526d8f2affc7b17c59 ]

The coresight components could be operated either in sysfs mode or in perf
mode. For some of the components, the mode of operation doesn't matter as
they simply relay the data to the next component in the trace path. But for
sinks, they need to be able to provide the trace data back to the user.
Thus we need to make sure that "mode" is handled appropriately. e.g,
the sysfs mode could have multiple sources driving the trace data, while
perf mode doesn't allow sharing the sink.

The coresight_enable_sink() however doesn't really allow this check to
trigger as it skips the "enable_sink" callback if the component is
already enabled, irrespective of the mode. This could cause mixing
of data from different modes or even same mode (in perf), if the
sources are different. Also, if we fail to enable the sink while
enabling a path (where sink is the first component enabled),
we could end up in disabling the components in the "entire"
path which were not enabled in this trial, causing disruptions
in the existing trace paths.

ARM: dts: rockchip: explicitly set vcc_sd0 pin to gpio on rk3188-radxarock

[ Upstream commit a2df0984e73fd9e1dad5fc3f1c307ec3de395e30 ]

It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.

The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.

[ Upstream commit 12ba7e1045521ec9f251c93ae0a6735cc3f42337 ]

Up until now, mlxsw tolerated firmware versions that weren't exactly
matching the required version, if the branch number matched. That
allowed the users to test various firmware versions as long as they were
on the right branch.

On the other hand, it made it impossible for mlxsw to put a hard lower
bound on a version that fixes all problems known to date. If a user had
a somewhat older FW version installed, mlxsw would start up just fine,
possibly performing non-optimally as it would use features that trigger
problematic behavior.

Therefore tweak the check to accept any FW version that is:

- on the same branch as the preferred version, and
- the same as or newer than the preferred version.

The microSD card slot in the Sapphire board is not working because of
several issues:
 1.- The vmmc power supply is missing in the DTS. It is capable of 3.0V
 and has a GPIO-based enable control.
 2.- The vqmmc power supply can provide up to 3.3V, but it is capped in
 the DTS to just 3.0V because of the vmmc capability. This results in a
 conflict from the mmc driver requesting an unsupportable voltage range
 from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
 range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
 See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
 3.- The card detect signal is non-working. There is a known conflict
 with jtag, but the workaround in drivers/soc/rockchip/grf.c does not
 work. Adding the broken-cd attribute to the DTS fixes the issue.

 * When using the old macros a line like
 *   setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);

PCI/AER: Don't read upstream ports below fatal errors

[ Upstream commit 9d938ea53b265ed6df6cdd1715d971f0235fdbfc ]

The AER driver has never read the config space of an endpoint that reported
a fatal error because the link to that device is considered unreliable.

An ERR_FATAL from an upstream port almost certainly indicates an error on
its upstream link, so we can't expect to reliably read its config space for
the same reason.

crypto: chacha20 - Fix chacha20_block() keystream alignment (again)

[ Upstream commit a5e9f557098e54af44ade5d501379be18435bfbf ]

In commit 9f480faec58c ("crypto: chacha20 - Fix keystream alignment for
chacha20_block()"), I had missed that chacha20_block() can be called
directly on the buffer passed to get_random_bytes(), which can have any
alignment.  So, while my commit didn't break anything, it didn't fully
solve the alignment problems.

Revert my solution and just update chacha20_block() to use
put_unaligned_le32(), so the output buffer need not be aligned.
This is simpler, and on many CPUs it's the same speed.

But, I kept the 'tmp' buffers in extract_crng_user() and
_get_random_bytes() 4-byte aligned, since that alignment is actually
needed for _crng_backtrack_protect() too.
