Merge tag 'oprofile-removal-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/linux

Pull oprofile and dcookies removal from Viresh Kumar:
 "Remove oprofile and dcookies support

  The 'oprofile' user-space tools don't use the kernel OPROFILE support
  any more, and haven't in a long time. User-space has been converted to
  the perf interfaces.

  The dcookies stuff is only used by the oprofile code. Now that
  oprofile's support is getting removed from the kernel, there is no
  need for dcookies as well.

  Remove kernel's old oprofile and dcookies support"
