Building with clang shows lots of warning like:
drivers/amba/bus.c:447:8: warning: implicit conversion from 'long long' to 'int' changes value from 4294967248 to -48
[-Wconstant-conversion]
static DECLARE_DELAYED_WORK(deferred_retry_work, amba_deferred_retry_func);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

struct delayed_work n = __DELAYED_WORK_INITIALIZER(n, f, 0)

ATOMIC_LONG_INIT(WORK_STRUCT_NO_POOL | WORK_STRUCT_STATIC)

include/asm-generic/atomic-long.h:32:41: note: expanded from macro 'ATOMIC_LONG_INIT'
#define ATOMIC_LONG_INIT(i) ATOMIC_INIT(i)
~~~~~~~~~~~~^~
arch/arm/include/asm/atomic.h:21:27: note: expanded from macro 'ATOMIC_INIT'
#define ATOMIC_INIT(i) { (i) }
~ ^
This makes the type cast explicit, which shuts up the warning.

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.
