Pull module updates from Petr Pavlu:

 - Ignore local labels and mapping symbols during module load

   These symbols were already ignored during kallsyms address-to-symbol
   lookups. Filter them out earlier during module loading to reduce
   lookup overhead and prevent them from appearing in /proc/kallsyms.

 - Fix potentially incorrect access of SetOnce<T> when setting Rust
   module parameters.

 - Fix a potential read of an uninitialized count when printing taint
   information for unloaded modules.

 - Allocate the kmod argument array using kmalloc_array() in preparation
   for conversion to type-aware allocators.

 - Clean up includes in linux/kmod.h

   Add explicit includes of linux/umh.h to files that use usermode
   helpers. Then clean up the #include list in linux/kmod.h, notably
   removing the compatibility linux/umh.h include.

 - Remove the error-injection.h include from linux/module.h

   Add explicit includes of linux/error-injection.h to files that use
   the ALLOW_ERROR_INJECTION() macro and currently rely on it being
   provided indirectly via linux/module.h. Then remove the unnecessary
   linux/error-injection.h include from linux/module.h.

 - Replace __MODULE_STRING() with __stringify() in various drivers in
   preparation for removing the former macro.

SMCCC-discovered firmware services are currently represented by separate
platform devices, such as smccc_trng and arm-cca-dev. Those devices do not
represent independent DT/ACPI-described platform resources; they are
features of the SMCCC firmware interface.

Add an Arm SMCCC bus for services discovered through the SMCCC firmware
interface. The bus provides SMCCC device and driver registration
helpers, function ID based matching, modalias generation, and a sysfs
modalias attribute so SMCCC service drivers can bind to discovered
firmware services and autoload as modules.

Follow-up changes can then register SMCCC firmware services as arm-smccc
devices instead of creating independent per-feature platform devices.

Based on arm_ffa code

SCMI client drivers already describe their bus match data with
MODULE_DEVICE_TABLE(scmi, ...), but modpost does not know how to consume
SCMI device tables. As a result, SCMI modules do not get generated module
aliases from their id tables.

Move struct scmi_device_id to mod_devicetable.h so it has a fixed layout
visible to modpost, add the corresponding generated offsets and teach
file2alias to emit scmi:<protocol>:<name> aliases.

Use the same stable alias format for SCMI device uevents and sysfs
modaliases. The previous string included the instance-specific device
name, which is not useful for matching modules.

The helper function is_mapping_symbol() historically checks for both
local labels prefixed with ".L" or "L0" and mapping symbols prefixed
with "$".

Rename it to is_ignored_kernel_symbol() to better reflect this actual
behavior and scope, preventing conceptual confusion.

While at it, update the related non-module files, no functional changes.

Convert all module name logging to use the mod_warn() and mod_error()
helpers, and pass the module to modpost_log() where used directly, to
always have the module name prefixed in the log message, with .ko suffix
for modules.

Pass struct module *mod around in a few places instead of just
mod->name.

Further unify the logging while at it. Use single quotes instead of
double quotes for symbols, sections, and namespaces. Explicitly state
it's a "symbol" when referencing symbols.

modpost has a lot of error logging with module name, but the module name
is logged in a plethora of ways. Add struct module * parameter to
modpost_log(), and wrappers mod_warn() and mod_error(), to allow logging
with a unified module name, if provided.

If the module is provided, the messages will be of the format:

(ERROR|WARNING): modpost: (modname.ko|vmlinux): message

Actual conversion is done separately.

The allocation for elf info symsearch and hdr from parse_elf() haven't
been released when return because of modname didn't have suffix ".o".
And it seems like the suffix ".o" check did not depends on parse_elf()
to succeed first. So, move the suffix ".o" check before checking
parse_elf() result to prevent resource leak when the modname didn't have
suffix ".o" and return early.

This is reported by Coverity Scan as "Resource leak".

Livepatch identifies a duplicate-named symbol by its position (sympos)
among same-named kallsyms entries, which for vmlinux are counted in
ascending address order in the final linked kernel.  That order can't be
reliably derived from vmlinux.o: the final link reorders sub-sections
(.text.unlikely*, .data..*, etc).

Bridge the gap with a new .klp.symid section which can be used to
correlate symbols between vmlinux.o and vmlinux so that klp-diff can
reliably determine the sympos.

The table can't survive --gc-sections: keeping it alive would keep every
duplicate-named symbol's section alive, so the reference kernel would
stop matching the one which ships.  klp-build rejects
CONFIG_LD_DEAD_CODE_DATA_ELIMINATION instead.  Nothing is lost today:
x86_64 is the only HAVE_KLP_BUILD arch and doesn't select
HAVE_LD_DEAD_CODE_DATA_ELIMINATION, arm64 and s390 have never selected
it either, and on powerpc, it's still EXPERIMENTAL and disabled by every
distro kernel.

This is the build-time half of reliable vmlinux sympos computation;
"objtool klp diff" will consume the table in a subsequent commit.
