TEXT_MAIN, DATA_MAIN and friends are defined differently depending on
whether certain config options enable -ffunction-sections and/or
-fdata-sections.
There's no technical reason for that beyond voodoo coding. Keeping the
separate implementations adds unnecessary complexity, fragments the
logic, and increases the risk of subtle bugs.
Unify the macros by using the same input section patterns across all
configs.
This is a prerequisite for the upcoming livepatch klp-build tooling
which will manually enable -ffunction-sections and -fdata-sections via
KCFLAGS.

The s390 indirect thunks are placed in the .text.__s390_indirect_jump_*
sections.
Certain config options which enable -ffunction-sections have a custom
version of the TEXT_TEXT macro:
.text.[0-9a-zA-Z_]*
That unintentionally matches the thunk sections, causing them to get
grouped with normal text rather than being handled by their intended
rule later in the script:
*(.text.*_indirect_*)
Fix that by adding another period to the thunk section names, following
the kernel's general convention for distinguishing code-generated text
sections from compiler-generated ones.

The objtool command line 'objtool --hacks=jump_label foo.o' on its own
should be expected to rewrite jump labels to NOPs. This means the
add_special_section_alts() code path needs to run when only this option
is provided.
This is mainly relevant in certain debugging situations, but could
potentially also fix kernel builds in which objtool is run with
--hacks=jump_label but without --orc, --stackval, --uaccess, or
--hacks=noinstr.

The run_readelf() function reads the entire output of readelf into a
single shell variable. For large object files with extensive debug
information, the size of this variable can exceed the system's
command-line argument length limit.
When this variable is subsequently passed to sed via `echo "${out}"`, it
triggers an "Argument list too long" error, causing the script to fail.
Fix this by redirecting the output of readelf to a temporary file
instead of a variable. The sed commands are then modified to read from
this file, avoiding the argument length limitation entirely.

The tools version of fixdep has broken dependencies. It doesn't get
rebuilt if the host compiler or headers change.
Build fixdep with the tools kbuild infrastructure, so fixdep runs on
itself. Due to the recursive dependency, its dependency file is
incomplete the very first time it gets built. In that case build it a
second time to achieve fixdep inception.

The race window between __scan_channels() and deliver_response() causes
the parameters of some channels to be set to 0.
1.[CPUA] __scan_channels() issues an IPMI request and waits with
wait_event() until all channels have been scanned.
wait_event() internally calls might_sleep(), which might
yield the CPU. (Moreover, an interrupt can preempt
wait_event() and force the task to yield the CPU.)
2.[CPUB] deliver_response() is invoked when the CPU receives the
IPMI response. After processing a IPMI response,
deliver_response() directly assigns intf->wchannels to
intf->channel_list and sets intf->channels_ready to true.
However, not all channels are actually ready for use.
3.[CPUA] Since intf->channels_ready is already true, wait_event()
never enters __wait_event(). __scan_channels() immediately
clears intf->null_user_handler and exits.
4.[CPUB] Once intf->null_user_handler is set to NULL, deliver_response()
ignores further IPMI responses, leaving the remaining
channels zero-initialized and unusable.
CPUA CPUB
------------------------------- -----------------------------
__scan_channels()
intf->null_user_handler

send_channel_info_cmd(intf,

------------------------------- -----------------------------
Fix the race between __scan_channels() and deliver_response() by
deferring both the assignment intf->channel_list = intf->wchannels
and the flag intf->channels_ready = true until all channels have
been successfully scanned or until the IPMI request has failed.

The commit a43ac325c7cb ("PCI: Set up bridge resources earlier") moved
bridge window resources set up earlier than before. The change was
necessary to support another change that got pulled on the last minute
due to breaking s390 and other systems.
The presence of valid bridge window resources earlier than before allows
pci_assign_unassigned_root_bus_resources() call from pci_host_probe()
assign the bridge windows. Some host bridges, however, have to wait first
for the link up event before they can enumerate successfully (see e.g.
qcom_pcie_global_irq_thread()) and thus the bus has not been enumerated yet
while calling pci_host_probe().
Calling pci_assign_unassigned_root_bus_resources() without results from
enumeration can result in sizing bridge windows with too small sizes which
cannot be later corrected after the enumeration has completed because
bridge windows have become pinned in place by the other resources.
Interestingly, it seems pci_read_bridge_bases() is not called at all in the
problematic case and the bridge window resource type setup is done by
pci_bridge_check_ranges() and sizing by the usual resource fitting logic.
The root problem behind all this looks pretty generic. If resource fitting
is called too early, the hotplug reservation and old size lower bounding
cause the bridge windows to be assigned without children but with non-zero
size, which leads to these pinning problems. As such, this can likely be
solved on the general level but the solution does not look trivial.
As the commit a43ac325c7cb ("PCI: Set up bridge resources earlier") was
prequisite for other change that did not end up into kernel yet, revert it
to resolve the resource assignment failures and give time to code and test
a generic solution.

The implementation follows the same pattern as other cgroup callbacks
like cgroup_set_weight() and cgroup_set_bandwidth(). It checks if the
BPF scheduler has implemented the callback and invokes it with the
appropriate parameters.

KASAN reports a stack-out-of-bounds access in validate_region_offset()
while running the cxl-poison.sh unit test because the printk format
specifier, %pr format, is not a match for the resource_size_t type of
the variables. %pr expects struct resource pointers and attempts to
dereference the structure fields, reading beyond the bounds of the

Since these messages emit an 'A exceeds B' type of message, keep

safe.

match_region_by_range() is not using the helper function that also takes
extended linear cache size into account when comparing regions. This
causes a x2 region to show up as 2 partial incomplete regions rather
than a single CXL region with extended linear cache support. Replace
the open coded compare logic with the proper helper function for
comparison. User visible impact is that when 'cxl list' is issued,
no activa CXL region(s) are shown. There may be multiple idle regions
present. No actual active CXL region is present in the kernel.

In order to compare the resource against the HMAT memory target,
the resource needs to be memory type. Change the DEFINE_RES()
macro to DEFINE_RES_MEM() in order to set the correct resource type.
hmat_get_extended_linear_cache_size() uses resource_contains()
internally. This causes a regression for platforms with the
extended linear cache enabled as the comparison always fails and the
cache size is not set. User visible impact is that when 'cxl list' is
issued, a CXL region with extended linear cache support will only
report half the size of the actual size. And this also breaks MCE
reporting of the memory region due to incorrect offset calculation
for the memory.

Enable proper pin multiplexing for the I2S1 8-channel transmit interface by
adding the default pinctrl configuration which esures correct signal routing
and avoids pinmux conflicts during audio playback.
Changes fix the error

I2S1 on the M1 to the codec in the RK809 only uses the SCLK, LRCK, SDI0
and SDO0 signals, so limit the claimed pins to those.
With this change audio output works as expected:

The sc_c field is currently not updated in the host response to the

dhchap queue context structure which is appropriately set during

Found via code inspection that when encode_message() fails in the middle
of processing, instead of returning the actual error code, it always
returns -EINVAL. This is because the entire message length has not been
processed, and the error code is set to -EINVAL.
Instead, take the 'out' path on failure to return the actual error code.

Replace manual rproc_add() and cleanup logic with devm_rproc_add(), which
ties the remoteproc lifecycle to the device's lifecycle. This simplifies
error handling and ensures proper cleanup.
With no need to invoke rproc_del(), the remove() ops could be removed.
No functional changes.

The big picture section of 2.Process.rst currently hardcodes major
version number to 5 since fb0e0ffe7fc8e0 ("Documentation: bring process
docs up to date"). As it can get outdated when it is actually
incremented (the recent is 6 and will be 7 in the near future),
arbitrarily bump it to 9, giving a headroom for a decade.
Note that the version number examples are kept to illustrate the
numbering scheme.

Replace the explicit call to imx_rproc_put_scu() in the remove path with
devm_add_action_or_reset(). Ensure proper cleanup of scu resources and
simplify the code by leveraging the device-managed resource framework.
Additionally:
- Remove the IMX_RPROC_SCU_API check from imx_rproc_put_scu(), as
devm_add_action_or_reset() now exclusively handles SCU cleanup.
- Improve error reporting by using dev_err_probe() for consistency and
clarity.
- Drop the err_put_scu label, as it is now redundant due to the updated
error handling approach.
No functional changes.

Replace separate calls to devm_clk_get() and clk_prepare_enable() with
devm_clk_get_enabled(), which combines clock acquisition and enabling
into a single managed step. Simplify the probe logic and remove the need
for manual clock disable in error and remove paths.
Also, update error handling to eliminate redundant cleanup steps and use
return-based error propagation where appropriate. Improve code clarity and
reduce the chance of resource leaks or incorrect ordering in cleanup paths.
No functional changes.
