  sysctl: replace child with an enumeration (2023-06-18 02:32:54 -0700)

----------------------------------------------------------------
v6.5-rc1-sysctl-next

The changes queued up for v6.5-rc1 for sysctl are in line with
prior efforts to stop usage of deprecated routines which incur
recursion and also make it hard to remove the empty array element
in each sysctl array declaration. The most difficult user to modify
was parport which required a bit of re-thinking of how to declare shared
sysctls there, Joel Granados has stepped up to the plate to do most of
this work and eventual removal of register_sysctl_table(). That work
ended up saving us about 1465 bytes according to bloat-o-meter. Since
we gained a few bloat-o-meter karma points I moved two rather small
sysctl arrays from kernel/sysctl.c leaving us only two more sysctl
arrays to move left.

Most changes have been tested on linux-next for about a month. The last
straggler patches are a minor parport fix, changes to the sysctl
kernel selftest so to verify correctness and prevent regressions for
the future change he made to provide an alternative solution for the
special sysctl mount point target which was using the now deprecated
sysctl child element.

This is all prep work to now finally be able to remove the empty
array element in all sysctl declarations / registrations which is
expected to save us a bit of bytes all over the kernel. That work
will be tested early after v6.5-rc1 is out.
