[PATCH v2 0/2] arm64: modules: Reject loading of malformed modules

["Adrian Barnaś" <abarnas@google.com>]

Hi all,

Here is version two of the patches I previously posted here:

  v1: https://lore.kernel.org/all/20250919122321.946462-1-abarnas@google.com/

Changes:
  * Renamed the parameter `is_module` to `skip_dry_run` in scs_patch()
  * Moved comments to module_finalize() and improve justification
  * Instead of rejecting all modules with callback, reject those with cb
    pointing outside core kernel text
  * Replace -EPERM to -ENOEXEC when rejecting modules with incorrect cb
  * Fix missing return in apply_alternatives_module() placeholder

Best regards
Adrian
