Merge tag 'modules-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux

Pull modules updates from Luis Chamberlain:
 "Finally something fun. Mike Rapoport does some cleanup to allow us to
  take out module_alloc() out of modules into a new paint shedded
  execmem_alloc() and execmem_free() so to make emphasis these helpers
  are actually used outside of modules.

  It starts with a non-functional changes API rename / placeholders to
  then allow architectures to define their requirements into a new shiny
  struct execmem_info with ranges, and requirements for those ranges.

  Archs now can intitialize this execmem_info as the last part of
  mm_core_init() if they have to diverge from the norm. Each range is a
  known type clearly articulated and spelled out in enum execmem_type.

  Although a lot of this is major cleanup and prep work for future
  enhancements an immediate clear gain is we get to enable KPROBES
  without MODULES now. That is ultimately what motiviated to pick this
  work up again, now with smaller goal as concrete stepping stone"
