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.
