Merge tag 'v6.5-rc1-sysctl-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux

Pull sysctl updates from Luis Chamberlain:
"The changes 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"

sysctl: move security keys sysctl registration to its own file

The security keys sysctls are already declared on its own file,
just move the sysctl registration to its own file to help avoid
merge conflicts on sysctls.c, and help with clearing up sysctl.c
further.

This creates a small penalty of 23 bytes:

sysctl_init_bases 85 59 -26
Total: Before=21256937, After=21256960, chg +0.00%

But soon we'll be saving tons of bytes anyway, as we modify the
sysctl registrations to use ARRAY_SIZE and so we get rid of all the
empty array elements so let's just clean this up now.

The show_unhandled_signals sysctl is the only sysctl for debug

array gets out of hand.

This change incurs simplifies sysctl registration by localizing
it where it should go for a penalty in size of increasing the
kernel by 23 bytes, we accept this given recent cleanups have
actually already saved us 1465 bytes in the prior commits.

sysctl: remove empty dev table

Now that all the dev sysctls have been moved out we can remove the
dev sysctl base directory. We don't need to create base directories,
they are created for you as if using 'mkdir -p' with register_syctl()
and register_sysctl_init(). For details refer to sysctl_mkdir_p()
usage.

We save 90 bytes with this changes:

./scripts/bloat-o-meter vmlinux.2.remove-sysctl-table vmlinux.3-remove-dev-table

dev_table 64 - -64
Total: Before=21257057, After=21256967, chg -0.00%

The empty dev table has been in place since the v2.5.0 days because
back then ordering was essentialy. But later commit 7ec66d06362d
("sysctl: Stop requiring explicit management of sysctl directories"),
merged as of v3.4-rc1, the entire ordering of directories was replaced
by allowing sysctl directory autogeneration. This new mechanism
introduced on v3.4 allows for sysctl directories to automatically be
created for sysctl tables when they are needed and automatically removes
them when no sysctl tables use them. That commit also added a dedicated
struct ctl_dir as a new type for these autogenerated directories.

sysctl: Refactor base paths registrations

This is part of the general push to deprecate register_sysctl_paths and
register_sysctl_table. The old way of doing this through
register_sysctl_base and DECLARE_SYSCTL_BASE macro is replaced with a
call to register_sysctl_init. The 5 base paths affected are: "kernel",
"vm", "debug", "dev" and "fs".

We remove the register_sysctl_base function and the DECLARE_SYSCTL_BASE
macro since they are no longer needed.

In order to quickly acertain that the paths did not actually change I
executed `find /proc/sys/ | sha1sum` and made sure that the sha was the
same before and after the commit.

We end up saving 563 bytes with this change:
