To help with debugging, print the type of the block rsv when we fail to
use our target block rsv in btrfs_use_block_rsv.
This now produces:
[ 544.672035] BTRFS: block rsv 1 returned -28
which is still cryptic without consulting the enum in block-rsv.h but I
guess it's better than nothing.

Some calls in the debugfs interface are made to the linux/uaccess.h header,
but the header is not referenced. So, for x86_64 architectures, this
dependency seems to be pulled in elsewhere, which leads to a successful
compilation. However, on arm/arm64 architectures, it was found to error out
on implicit declarations.
This change fixes the implicit declaration error by adding the
linux/uaccess.h header.

It appears that simplification of mcp23s08_spi_regmap_init() made
a regression due to wrong size calculation for dev_kmemdup() call.
It misses the fact that config variable is already a pointer, thus
the sizeof() calculation is wrong and only 4 or 8 bytes were copied.
Fix the parameters to devm_kmemdup() to copy a full chunk of memory.

The mcp2221 driver GPIO output handling has has several issues.
* A wrong value is used for the GPIO direction.
* Wrong offsets are calculated for some GPIO set value/set direction
operations, when offset is larger than 0.
This has been fixed by introducing proper manifest constants for the
direction encoding, and using 'offsetof' when calculating GPIO
register offsets.
The updated driver has been tested with the Sparx5 pcb134/pcb135
board, which has the mcp2221 device with several (output) GPIO's.

Use the uic_cmd->cmd_active as a flag to track the lifecycle of an UIC cmd.
The flag is set before sending the UIC cmd and cleared in IRQ handler. When
a PMC or UIC cmd completion timeout happens, if the flag is not set,
instead of returning timeout error, we still treat it as a successful
operation. This is to deal with the scenario in which completion has been
raised but the one waiting for the completion cannot be awaken in time due
to kernel scheduling problem.

The scsi_block_reqs_cnt increased in ufshcd_hold() is supposed to be
decreased back in ufshcd_ungate_work() in a paired way. However, if
specific ufshcd_hold/release sequences are met, it is possible that
scsi_block_reqs_cnt is increased twice but only one ungate work is
queued. To make sure scsi_block_reqs_cnt is handled by ufshcd_hold() and
ufshcd_ungate_work() in a paired way, increase it only if queue_work()
returns true.

Network problems with RTL8125B have been reported [0] and with help
from Realtek it turned out that this chip version has a hw problem
with short packets (similar to RTL8168evl). Having said that activate
the same workaround as for RTL8168evl.
Realtek suggested to activate the workaround for RTL8125A too, even
though they're not 100% sure yet which RTL8125 versions are affected.

noc/axi/ahb are bus clk, not peripheral clk.
Since peripheral clk has a limitation that for peripheral clock slice,
IP clock slices must be stopped to change the clock source.
However if the bus clk is marked as critical clk peripheral, the
assigned clock parent operation will fail.
So we added CLK_SET_PARENT_GATE flag to avoid glitch.
And add imx8m_clk_hw_composite_bus_critical for bus critical clock usage

Andreas reported that commit ee0a49a6870e ("powerpc/uaccess: Switch
__put_user_size_allowed() to __put_user_asm_goto()") broke
CLONE_CHILD_SETTID.
Further inspection showed that the put_user() in schedule_tail() was
missing entirely, the store not emitted by the compiler.
<.schedule_tail>:
mflr r0
std r0,16(r1)
stdu r1,-112(r1)

b <.schedule_tail+0x1c>
Notice there are no stores other than to the stack. There should be a
stw in there for the store to current->set_child_tid.
This is only seen with GCC 4.9 era compilers (tested with 4.9.3 and
4.9.4), and only when CONFIG_PPC_KUAP is disabled.
When CONFIG_PPC_KUAP=y, the inline asm that's part of the isync()
and mtspr() inlined via allow_user_access() seems to be enough to
avoid the bug.
We already have a macro to work around this (or a similar bug), called
asm_volatile_goto which includes an empty asm block to tickle the
compiler into generating the right code. So use that.
With this applied the code generation looks more like it will work:

Some messages sent by the MDS entail a session sequence number
increment, and the MDS will drop certain types of requests on the floor
when the sequence numbers don't match.
In particular, a REQUEST_CLOSE message can cross with one of the
sequence morphing messages from the MDS which can cause the client to
stall, waiting for a response that will never come.
Originally, this meant an up to 5s delay before the recurring workqueue
job kicked in and resent the request, but a recent change made it so
that the client would never resend, causing a 60s stall unmounting and
sometimes a blockisting event.
Add a new helper for incrementing the session sequence and then testing
to see whether a REQUEST_CLOSE needs to be resent, and move the handling
of CEPH_MDS_SESSION_CLOSING into that function. Change all of the
bare sequence counter increments to use the new helper.
Reorganize check_session_state with a switch statement. It should no
longer be called when the session is CLOSING, so throw a warning if it
ever is (but still handle that case sanely).

With commit 669cbc708122 ("PCI: Move DT resource setup into
devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated
into resources when the host bridge is allocated. The resources are
requested as well, but that happens a second time for the mvebu driver in
mvebu_pcie_parse_request_resources(). We should only be requesting the
additional resources added in mvebu_pcie_parse_request_resources(). These
are not added by default because they use custom properties rather than
standard DT address translation.
Also, the bus ranges was also populated by default, so we can remove it
from mvebu_pci_host_probe().

Prior to commit 0f71c60ffd26 ("PCI: dwc: Remove storing of PCI resources"),
the DWC driver was setting up the last memory resource rather than the
first memory resource. This doesn't matter for most platforms which only
have 1 memory resource, but it broke Tegra194 which has a 2nd
(prefetchable) memory region that requires an ATU entry. The first region
on Tegra194 relies on the default 1:1 pass-thru of outbound transactions
and doesn't need an ATU entry.

Oliver Hartkopp's patch fixes the length calculation for RTR CAN frames
in the __can_get_echo_skb() helper.
Oleksij Rempel's patch fixes a use-after-free that shows up with j1939 in
can_create_echo_skb().
Yegor Yefremov contributes 4 patches to enhance the j1939 documentation.
Zhang Changzhong's patch fixes a hanging task problem in j1939_sk_bind()
if the netdev is down.
Then there are three patches for the newly added CAN_ISOTP protocol. Geert
Uytterhoeven enhances the kconfig help text. Oliver Hartkopp's patch adds
missing RX timeout handling in listen-only mode and Colin Ian King's patch
decreases the generated object code by 926 bytes.
Zhang Changzhong contributes a patch for the ti_hecc driver that fixes the
error path in the probe function.
Navid Emamdoost's patch for the xilinx_can driver fixes the error handling
in case of failing pm_runtime_get_sync().
There are two patches for the peak_usb driver. Dan Carpenter adds range
checking in decode operations and Stephane Grosjean's patch fixes
a timestamp wrapping problem.
Stephane Grosjean's patch for th peak_canfd driver fixes echo management if
loopback is on.
The next three patches all target the mcp251xfd driver. The first one is
by me and it increased the severity of CRC read error messages. The kernel
test robot removes an unneeded semicolon and Tom Rix removes unneeded
break in several switch-cases.
The last 4 patches are by Joakim Zhang and target the flexcan driver,
the first three fix ECC related device specific quirks for the LS1021A,
LX2160A and the VF610 SoC. The last patch disable wakeup completely upon
driver remove.

In order for topology to be resource managed, change all allocations to
be resource managed:
k*alloc -> devm_k*alloc
kstrdup -> devm_kstrdup
Exceptions where non resource managed allocation is left is
soc_tplg_dapm_widget_create(), as it uses pointer to memory locally and
frees it up after use, as well as soc_tplg_dapm_graph_elems_load(),
which has temporary pointer to table of routes.
After conversion all redundant calls in error and clean up paths were
removed.
Also removed some variables which become unneeded when there is no calls
using them.

Since commit 530b5affc675 ("spi: fsl-dspi: fix use-after-free in

in dspi_suspend/resume.
This is because since this commit, the drivers private data point to
"dspi" instead of "ctlr", the codes in suspend and resume func were
not modified correspondly.

We can't bundle this into one operation, as the identity may not have
originated from the tctx to begin with. Drop one ref for each of them
separately, if they don't match the static assignment. If we don't, then
if the identity is a lookup from registered credentials, we could be
freeing that identity as we're dropping a reference assuming it came from
the tctx. syzbot reports this as a use-after-free, as the identity is
still referencable from idr lookup:

When an exception/interrupt hits kernel space and the kernel is not
currently in the idle task then RCU must be watching.
irqentry_enter() validates this via rcu_irq_enter_check_tick(), which in
turn invokes lockdep when taking a lock. But at that point lockdep does not
yet know about the fact that interrupts have been disabled by the CPU,
which triggers a lockdep splat complaining about inconsistent state.
Invoking trace_hardirqs_off() before rcu_irq_enter_check_tick() defeats the
point of rcu_irq_enter_check_tick() because trace_hardirqs_off() uses RCU.
So use the same sequence as for the idle case and tell lockdep about the
irq state change first, invoke the RCU check and then do the lockdep and
tracer update.
