coccicheck prints debug logs to stdout unless a debug file has been set.
This makes it hard to read coccinelle's suggested changes, especially
for someone new to coccicheck.
From this commit, we warn about this behaviour from within the script on
an unset debug file. Explicitly setting the debug file to /dev/null
suppresses the warning while keeping the default.

After goto restart, optind retains its advanced position from the
previous getopt loop, causing getopt() to immediately return -1.
This silently drops all command-line options on the restarted skeleton.
Reset optind to 1 at the restart label so options are re-parsed.

scx_sdt, scx_cpu0.

The stats thread reads nr_vruntime_enqueues, nr_vruntime_dispatches,
nr_vruntime_failed, and nr_curr_enqueued concurrently with the main
thread writing them, with no synchronization.
Use __atomic builtins with relaxed ordering for all accesses to these
counters to eliminate the data races.
Only display accuracy is affected, not scheduling correctness.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Fix possible dereference of uninitialized pointer
When validating the persistent ring buffer on boot up, if the first
validation fails, a reference to "head_page" is performed in the
error path, but it skips over the initialization of that variable.
Move the initialization before the first validation check.
- Fix use of event length in validation of persistent ring buffer
On boot up, the persistent ring buffer is checked to see if it is
valid by several methods. One being to walk all the events in the
memory location to make sure they are all valid. The length of the
event is used to move to the next event. This length is determined by
the data in the buffer. If that length is corrupted, it could
possibly make the next event to check located at a bad memory
location.
Validate the length field of the event when doing the event walk.
- Fix function graph on archs that do not support use of ftrace_ops
When an architecture defines HAVE_DYNAMIC_FTRACE_WITH_ARGS, it means
that its function graph tracer uses the ftrace_ops of the function
tracer to call its callbacks. This allows a single registered
callback to be called directly instead of checking the callback's
meta data's hash entries against the function being traced.
For architectures that do not support this feature, it must always
call the loop function that tests each registered callback (even if
there's only one). The loop function tests each callback's meta data
against its hash of functions and will call its callback if the
function being traced is in its hash map.
The issue was that there was no check against this and the direct
function was being called even if the architecture didn't support it.
This meant that if function tracing was enabled at the same time as a
callback was registered with the function graph tracer, its callback
would be called for every function that the function tracer also
traced, even if the callback's meta data only wanted to be called
back for a small subset of functions.
Prevent the direct calling for those architectures that do not
support it.
- Fix references to trace_event_file for hist files
The hist files used event_file_data() to get a reference to the
associated trace_event_file the histogram was attached to. This would
return a pointer even if the trace_event_file is about to be freed
(via RCU). Instead it should use the event_file_file() helper that
returns NULL if the trace_event_file is marked to be freed so that no
new references are added to it.
- Wake up hist poll readers when an event is being freed
When polling on a hist file, the task is only awoken when a hist
trigger is triggered. This means that if an event is being freed
while there's a task waiting on its hist file, it will need to wait
until the hist trigger occurs to wake it up and allow the freeing to
happen. Note, the event will not be completely freed until all
references are removed, and a hist poller keeps a reference. But it
should still be woken when the event is being freed.

The ./qp*/stats debugfs file for each NTB transport QP is currently
implemented with a hand-crafted kmalloc() buffer and a series of
scnprintf() calls. This is a pre-seq_file style pattern and makes future
extensions easy to truncate.
Convert the stats file to use the seq_file helpers via
DEFINE_SHOW_ATTRIBUTE(), which simplifies the code and lets the seq_file
core handle buffering and partial reads.

The buffer used for "qp%d" was only 4 bytes, which truncates names like
"qp10" to "qp1" and causes multiple queues to share the same directory.
Enlarge the buffer and use sizeof() to avoid truncation.

tool_peer_mw_trans_write
The sscanf() call in tool_peer_mw_trans_write() uses "%lli:%zi" to parse
user input into 'u64 addr' and 'size_t wsize'. This is incorrect:
- "%lli" expects a signed long long *, but 'addr' is u64 (unsigned).
Input like "0x8000000000000000" is misinterpreted as negative,
leading to corrupted address values.
- "%zi" expects a signed ssize_t *, but 'wsize' is size_t (unsigned).
Input of "-1" is successfully parsed and stored as SIZE_MAX
(e.g., 0xFFFFFFFFFFFFFFFF), which may cause buffer overflows
or infinite loops in subsequent memory operations.
Fix by using format specifiers that match the actual variable types:
- "%llu" for u64 (supports hex/decimal, standard for kernel u64 parsing)
- "%zu" for size_t (standard and safe; rejects negative input)

Some platforms (e.g. R-Car S4) do not gain from using a DMAC on TX path
in ntb_transport and end up CPU-bound on memcpy_toio(). Add a module
parameter 'tx_memcpy_offload' that moves the TX memcpy_toio() and
descriptor writes to a per-QP kernel thread. It is disabled by default.
This change also fixes a rare ordering hazard in ntb_tx_copy_callback(),
that was observed on R-Car S4 once throughput improved with the new
module parameter: the DONE flag write to the peer MW, which is WC
mapped, could be observed after the DB/MSI trigger. Both operations are
posted PCIe MWr (often via different OB iATUs), so WC buffering and
bridges may reorder visibility. Insert dma_mb() to enforce store->load
ordering and then read back hdr->flags to flush the posted write before
ringing the doorbell / issuing MSI.
While at it, update tx_index with WRITE_ONCE() at the earlier possible
location to make ntb_transport_tx_free_entry() robust.

dw_pcie_ep_set_bar() currently tears down existing inbound mappings only
when either the previous or the new struct pci_epf_bar uses submaps
(num_submap != 0). If both the old and new mappings are BAR Match Mode,
reprogramming the same ATU index is sufficient, so no explicit teardown
was needed.
However, some callers may reuse the same struct pci_epf_bar instance and
update it in place before calling set_bar() again. In that case
ep_func->epf_bar[bar] and the passed-in epf_bar can point to the same
object, so we cannot reliably distinguish BAR Match Mode -> BAR Match Mode
from Address Match Mode -> BAR Match Mode. As a result, the conditional
teardown based on num_submap becomes unreliable and existing inbound maps
may be left active.
Call dw_pcie_ep_clear_ib_maps() unconditionally before reprogramming the
BAR so that in-place updates are handled correctly.
This introduces a behavioral change in a corner case: if a BAR
reprogramming attempt fails (especially for the long-standing BAR Match
Mode -> BAR Match Mode update case), the previously programmed inbound
mapping will already have been torn down. This should be acceptable, since
the caller observes the error and should not use the BAR for any real
transactions in that case.
While at it, document that the existing update parameter check is
best-effort for in-place updates.

dw_pcie_ep_clear_ib_maps() first checks whether the inbound mapping for a
BAR is in BAR Match Mode (tracked via ep_func->bar_to_atu[bar]). Once
found, the iATU region is disabled and the bookkeeping is cleared.
BAR Match Mode and Address Match Mode mappings are mutually exclusive for a
given BAR, so there is nothing left for the Address Match Mode teardown
path to do after the BAR Match Mode mapping has been removed.
Return early after clearing the BAR Match Mode mapping to avoid running the
Address Match Mode teardown path. This makes the helper's intention
explicit and helps detect incorrect use of pci_epc_set_bar().
