[0/3] module: Make .static_call_sites read-only after init

Message

Section .static_call_sites holds data structures that need to be sorted and
processed only at module load time. The section is never modified afterwards.
Make it therefore read-only after module initialization to avoid any
(non-)accidental modifications.

Petr Pavlu (3):
  module: Constify parameters of module_enforce_rwx_sections()
  module: Add a separate function to mark sections as read-only after
    init
  module: Make .static_call_sites read-only after init
