Merge tag 'sysctl-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl

Pull sysctl updates from Joel Granados:

 - Move kern_table members out of kernel/sysctl.c

   Moved a subset (tracing, panic, signal, stack_tracer and sparc) out
   of the kern_table array. The goal is for kern_table to only have
   sysctl elements. All this increases modularity by placing the
   ctl_tables closer to where they are used while reducing the chances
   of merge conflicts in kernel/sysctl.c.

 - Fixed sysctl unit test panic by relocating it to selftests

* tag 'sysctl-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl:
  sysctl: Close test ctl_headers with a for loop
  sysctl: call sysctl tests with a for loop
  sysctl: Add 0012 to test the u8 range check
  sysctl: move u8 register test to lib/test_sysctl.c
  sparc: mv sparc sysctls into their own file under arch/sparc/kernel
  stack_tracer: move sysctl registration to kernel/trace/trace_stack.c
  tracing: Move trace sysctls into trace.c
  signal: Move signal ctl tables into signal.c
  panic: Move panic ctl tables into panic.c
