In commiteb631bb5bf("arm64: Support arch_irq_work_raise() via self IPIs") a new function "arch_irq_work_raise" was added without a prototype. In commitd914d4d497("arm64: Implement panic_smp_self_stop()") a new function "panic_smp_self_stop" was added without a prototype. We get the following warnings on W=1: arch/arm64/kernel/smp.c:842:6: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes] arch/arm64/kernel/smp.c:862:6: warning: no previous prototype for ‘panic_smp_self_stop’ [-Wmissing-prototypes] Fix the warnings by: 1. Adding the prototype for 'arch_irq_work_raise' in irq_work.h 2. Adding the prototype for 'panic_smp_self_stop' in smp.h Signed-off-by: Chen Lifu <chenlifu@huawei.com> Link: https://lore.kernel.org/r/20210329034343.183974-1-chenlifu@huawei.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
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.
