PCI: brcmstb: Configure HW CLKREQ# mode appropriate for downstream device
The Broadcom STB/CM PCIe HW core, which is also used in RPi SOCs, must be
deliberately set by the PCIe RC HW into one of three mutually exclusive
modes:
"safe" -- No CLKREQ# expected or required, refclk is always provided. This
mode should work for all devices but is not be capable of any refclk
power savings.
"no-l1ss" -- CLKREQ# is expected to be driven by the downstream device for
CPM and ASPM L0s and L1. Provides Clock Power Management, L0s, and L1,
but cannot provide L1 substate (L1SS) power savings. If the downstream
device connected to the RC is L1SS capable AND the OS enables L1SS, all
PCIe traffic may abruptly halt, potentially hanging the system.
"default" -- Bidirectional CLKREQ# between the RC and downstream device.
Provides ASPM L0s, L1, and L1SS, but not compliant to provide Clock
Power Management; specifically, may not be able to meet the T_CLRon max
timing of 400ns as specified in "Dynamic Clock Control", section
3.2.5.2.2 of the PCIe Express Mini CEM 2.1 specification. This
situation is atypical and should happen only with older devices.
Previously, this driver always set the mode to "no-l1ss", as almost all
STB/CM boards operate in this mode. But now there is interest in
activating L1SS power savings from STB/CM customers, which requires "aspm"
mode. In addition, a bug was filed for RPi4 CM platform because most
devices did not work in "no-l1ss" mode.
Note that the mode is specified by the DT property "brcm,clkreq-mode". If
this property is omitted, then "default" mode is chosen.
Note: Since L1 substates are now possible, a modification was made
regarding an internal bus timeout: During long periods of the PCIe RC HW
being in an L1SS sleep state, there may be a timeout on an internal bus
access, even though there may not be any PCIe access involved. Such a
timeout will cause a subsequent CPU abort.
The Broadcom STB/CM PCIe HW -- a core that is also used by RPi SOCs --
requires the driver to deliberately place the RC HW one of three CLKREQ#
modes. The "brcm,clkreq-mode" property allows the user to override the
default setting. If this property is omitted, the default mode shall be
"default".
PCI: keystone: Fix race condition when initializing PHYs
The PCI driver invokes the PHY APIs using the ks_pcie_enable_phy()
function. The PHY in this case is the Serdes. It is possible that the
PCI instance is configured for two lane operation across two different
Serdes instances, using one lane of each Serdes.
In such a configuration, if the reference clock for one Serdes is
provided by the other Serdes, it results in a race condition. After the
Serdes providing the reference clock is initialized by the PCI driver by
invoking its PHY APIs, it is not guaranteed that this Serdes remains
powered on long enough for the PHY APIs based initialization of the
dependent Serdes. In such cases, the PLL of the dependent Serdes fails
to lock due to the absence of the reference clock from the former Serdes
which has been powered off by the PM Core.
Fix this by obtaining reference to the PHYs before invoking the PHY
initialization APIs and releasing reference after the initialization is
complete.
The current code calculated some dbi[2] registers' offset by calling
dw_pcie_ep_get_dbi[2]_offset() in each function. To improve the code
readability, add dw_pcie_ep_{read,write}_dbi[2} and some data-width
related helpers.

From: Maarten Lankhorst <[email protected]>
[sima: Stitch together both changelogs from Maarten. Also because of
branch history this contains a few more bugfixes which are already in
v6.6, but I didn't feel like this justifies some backmerge since there
wasn't any real conflict.] Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

cifs: handle when server stops supporting multichannel
When a server stops supporting multichannel, we will
keep attempting reconnects to the secondary channels today.
Avoid this by freeing extra channels when negotiate
returns no multichannel support.

Missing field not being returned in ioctl CIFS_IOC_GET_MNT_INFO
The tcon_flags field was always being set to zero in the information
about the mount returned by the ioctl CIFS_IOC_GET_MNT_INFO instead
of being set to the value of the Flags field in the tree connection
structure as intended.

parisc: Prevent booting 64-bit kernels on PA1.x machines
Bail out early with error message when trying to boot a 64-bit kernel on
32-bit machines. This fixes the previous commit to include the check for
true 64-bit kernels as well.

spi: Fix null dereference on suspend
A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.
Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
called which dereferences cur_msg (which is now NULL)
Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.
tracing: fprobe-event: Fix to check tracepoint event and return
Fix to check the tracepoint event is not valid with $retval.
The commit 08c9306fc2e3 ("tracing/fprobe-event: Assume fprobe is
a return event by $retval") introduced automatic return probe
conversion with $retval. But since tracepoint event does not
support return probe, $retval is not acceptable.
Without this fix, ftracetest, tprobe_syntax_errors.tc fails;
[22] Tracepoint probe event parser error log check [FAIL]

So 't kfree $retval' should fail (tracepoint doesn't support
return probe) but passed it.
Most architectures that support kprobes declare this function in their
own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:
kernel/kprobes.c:1865:12: error: no previous prototype for 'kprobe_exceptions_notify' [-Werror=missing-prototypes]
1865 | int __weak kprobe_exceptions_notify(struct notifier_block *self,
Move the prototype into linux/kprobes.h so it is visible to all
the definitions.
