If compiling the arm64 kernel with W=1 the following warning is produced: | arch/arm64/kernel/vdso/vgettimeofday.c:9:5: error: no previous prototype for ‘__kernel_clock_gettime’ [-Werror=missing-prototypes] | 9 | int __kernel_clock_gettime(clockid_t clock, | | ^~~~~~~~~~~~~~~~~~~~~~ | arch/arm64/kernel/vdso/vgettimeofday.c:15:5: error: no previous prototype for ‘__kernel_gettimeofday’ [-Werror=missing-prototypes] | 15 | int __kernel_gettimeofday(struct __kernel_old_timeval *tv, | | ^~~~~~~~~~~~~~~~~~~~~ | arch/arm64/kernel/vdso/vgettimeofday.c:21:5: error: no previous prototype for ‘__kernel_clock_getres’ [-Werror=missing-prototypes] | 21 | int __kernel_clock_getres(clockid_t clock_id, | | ^~~~~~~~~~~~~~~~~~~~~ This patch removes "-Wmissing-prototypes" and "-Wmissing-declarations" compilers flags from the compilation of vgettimeofday.c to make possible to build the kernel with CONFIG_WERROR enabled.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
