We should use of_node_put() for the reference 'node' returned by
of_parse_phandle() which will increase the refcount.

We have sanity checks for byte controls and if any of the fail the locally
allocated scontrol->ipc_control_data is freed up, but not set to NULL.
On a rollback path of the error the higher level code will also try to free
the scontrol->ipc_control_data which will eventually going to lead to
memory corruption as double freeing memory is not a good thing.

When creating a snapshot of the NVM the driver needs to read the entire
contents from the NVM and store it. The NVM reads are protected by a lock
that is shared between the driver and the firmware.
If the driver takes too long to read the entire NVM (which can happen on
some systems) then the firmware could reclaim the lock and cause subsequent
reads from the driver to fail.
We could fix this by increasing the timeout that we pass to the firmware,
but we could end up in the same situation again if the system is slow.
Instead have the driver break the reading of the NVM into blocks that are
small enough that we have confidence that the read will complete within the
timeout time, but large enough not to cause significant AQ overhead.

The driver currently presumes that the record data in the PLDM header
of the firmware image will match the device ID of the running device.
This is true for E810 devices. It appears that for E822 devices that
this is not guaranteed to be true.
Fix this by adding a check for the generic E822 device.

In cifs_put_smb_ses, when we're freeing the last ref count to
the session, we need to free up each channel. At this point,
it is unnecessary to take chan_lock, since we have the last
reference to the ses.
Picking up this lock also introduced a deadlock because it calls
cifs_put_tcp_ses, which locks cifs_tcp_ses_lock.

On failure to create a new channel, first cancel the
delayed threads, which could try to search for this
channel, and not find it.
The other option was to put the tcp session for the
channel first, before decrementing chan_count. But
that would leave a reference to the tcp session, when
it has been freed already.
So going with the former option and cancelling the
delayed works first, before rolling back the channel.

Some PCI Endpoint controllers integrate an eDMA (embedded DMA). eDMA can
bypass the outbound memory address translation unit to access all RC memory
space.
Add eDMA support for pci-epf-test.
Depending on HW availability, the EPF test can use either eDMA or general
system DMA controllers to perform DMA. The test tries to use eDMA first and
falls back to general system DMA controllers if there's no eDMA
Separate dma_chan to dma_chan_tx and dma_chan_rx. Search for an eDMA
channel first, then search for a memory-to-memory DMA channel. If general
memory to memory channels are used, dma_chan_rx = dma_chan_tx.
Add dma_addr_t dma_remote in pci_epf_test_data_transfer() because eDMA uses
remote RC physical address directly.
Add enum dma_transfer_direction dir in pci_epf_test_data_transfer() because
eDMA chooses the correct RX/TX channel by dir.
The overall steps are:
1. Execute dma_request_channel() and filter function to find correct eDMA
RX and TX Channel. If a channel does not exist, fallback to try to
allocate general memory to memory DMA channel.
2. Execute dmaengine_slave_config() to configure remote side physical
address.
3. Execute dmaengine_prep_slave_single() to create transfer descriptor.
4. Execute tx_submit().
5. Execute dma_async_issue_pending()

pcie_aspm_pm_state_change() was introduced at the inception of PCIe ASPM
code, but it can cause some issues. For instance, when ASPM config is
changed via sysfs, those changes won't persist across power state change
because pcie_aspm_pm_state_change() overwrites them.
Also, if the driver restores L1SS [1] after system resume, the restored
state will also be overwritten by pcie_aspm_pm_state_change().
Remove pcie_aspm_pm_state_change(). If there's any hardware that really
needs it to function, a quirk can be used instead.

There is a corner case with Tegra30, where we want to skip clk
configuration that happens via dev_pm_opp_set_opp(), but still want the
OPP core to read the "opp-hz" property so we can find the right OPP via
freq finding helpers.
The OPP core provides support for the platforms to provide config_clks
helpers now, lets use that instead of devm_pm_opp_of_add_table_noclk()
to achieve the same result, as the OPP core won't parse the DT's
"opp-hz" property anymore if the clock isn't provided.

This patch adds support to allow multiple clocks for a device.
The design is pretty much similar to how this is done for regulators,
and platforms can supply their own version of the config_clks() callback
if they have multiple clocks for their device. The core manages the
calls via opp_table->config_clks() eventually.
We have kept both "clk" and "clks" fields in the OPP table structure and
the reason is provided as a comment in _opp_set_clknames(). The same
isn't done for "rates" though and we use rates[0] at most of the places
now.

Currently, test_bitmap_arr64() only tests bitmap_to_arr64()'s sanity
by comparing the result of double-conversion (bm -> arr64 -> bm2)
with the input bitmap. However, this may be not enough when one side
hides bugs of the second one (e.g. tail clearing, which is being
performed by both).
Expand the tests and check the tail of the actual arr64 used as
a temporary buffer for double-converting.

GENMASK*() family takes the first and the last bits of the mask
*including* them. So, with the current code bitmap_to_arr64()

nbits % exp mask must be
1 GENMASK(1, 0) 0x3 0x1
...
63 GENMASK(63, 0) 0xffffffffffffffff 0x7fffffffffffffff
This was found by making the function always available instead of
32-bit BE systems only (for reusing in some new functionality).
Turn the number of bits into the last bit set by subtracting 1.
@nbits is already checked to be positive beforehand.

The valid values of nfs options port and mountport are 0 to USHRT_MAX.
The fs parser will return a fail for port values that are negative
and the sloppy option handling then returns success.
But the sloppy option handling is meant to return success for invalid
options not valid options with invalid values.
Restricting the sloppy option override to handle failure returns for
invalid options only is sufficient to resolve this problem.

The FSR (Firmware State Register) can be found at offset 0 in the SRAM and
it is holding information about the state of the ROM/FW.
In case of a boot failure it can be used to get the state where the boot
process got stuck, it does not itself contains error codes as such.
The error code (or the firmware state information) is stored in the next
soft register at offset 0x4.

The lock contention tracepoints don't provide lock names. All we can
do is to get stack traces and show the caller instead. To minimize
the overhead it's limited to up to 8 stack traces and display the
first non-lock function symbol name as a caller.

Currently it has no interface to specify the max stack depth for perf
record. Extend the command line parameter to accept a number after
'fp' to specify the depth like '--call-graph fp,32'.

When the lock contention events are used, there's no tracking of
acquire and release. So the state machine is simplified to use
UNINITIALIZED -> CONTENDED -> ACQUIRED only.
Note that CONTENDED state is re-entrant since mutex locks can hit two
or more consecutive contention_begin events for optimistic spinning
and sleep.

When LOCKDEP and LOCK_STAT events are not available, it falls back to
record the new lock contention tracepoints.
