If no spinlock debugging options (CONFIG_GENERIC_LOCKBREAK,
CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_LOCK_ALLOC) are enabled on a UP
platform (e.g. m68k defconfig), arch_spinlock_t is an empty struct,
hence using ARRAY_SIZE(nf_nat_locks) causes a division by zero:
net/netfilter/nf_nat_core.c: In function ‘nf_nat_setup_info’:
net/netfilter/nf_nat_core.c:432: warning: division by zero
net/netfilter/nf_nat_core.c: In function ‘__nf_nat_cleanup_conntrack’:
net/netfilter/nf_nat_core.c:535: warning: division by zero
net/netfilter/nf_nat_core.c:537: warning: division by zero
net/netfilter/nf_nat_core.c: In function ‘nf_nat_init’:
net/netfilter/nf_nat_core.c:810: warning: division by zero
net/netfilter/nf_nat_core.c:811: warning: division by zero
net/netfilter/nf_nat_core.c:824: warning: division by zero
Fix this by using the CONNTRACK_LOCKS definition instead.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
