[merged] sysctl-add-register_sysctl-dummy-helper.patch removed from -mm tree

[akpm]

The patch titled
     Subject: sysctl: add register_sysctl() dummy helper
has been removed from the -mm tree.  Its filename was
     sysctl-add-register_sysctl-dummy-helper.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Arnd Bergmann <arnd@arndb.de>
Subject: sysctl: add register_sysctl() dummy helper

register_sysctl() 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")
