  selftests/sysctl: fix wording of help messages (2025-02-27 10:02:12 +0100)

----------------------------------------------------------------
Summary

* Move vm_table members out of kernel/sysctl.c

  All vm_table array members have moved to their respective subsystems leading
  to the removal of vm_table from kernel/sysctl.c. This increases modularity by
  placing the ctl_tables closer to where they are actually used and at the same
  time reducing the chances of merge conflicts in kernel/sysctl.c.

* ctl_table range fixes

  Replace the proc_handler function that checks variable ranges in
  coredump_sysctls and vdso_table with the one that actually uses the extra{1,2}
  pointers as min/max values. This tightens the range of the values that users
  can pass into the kernel effectively preventing {under,over}flows.

* Misc fixes

  Correct grammar errors and typos in test messages. Update sysctl files in
  MAINTAINERS. Constified and removed array size in declaration for
  alignment_tbl

* Testing

  - These have all been in linux-next for at least 1 month
  - They have gone through 0-day
  - Ran all these through sysctl selftests in x86_64
