The register_sysctl() function has been around for five years with commit
fea478d4101a ("sysctl: Add register_sysctl for normal sysctl users")
but now that arm64 started using it, I ran into a compile error:
arch/arm64/kernel/armv8_deprecated.c: In function 'register_insn_emulation_sysctl':
arch/arm64/kernel/armv8_deprecated.c:257:2: error: implicit declaration of function 'register_sysctl'
This adds a inline function like we already have for register_sysctl_paths()
and register_sysctl_table().
Fixes: 38b9aeb32fa7 ("arm64: Port deprecated instruction emulation to new sysctl interface")

This should probably get merged through the arm64 tree to avoid
bisection problems.
