The helpers in proton-pack.c are called from assembler and have no prototype in a header, which causes a W=1 warning: arch/arm64/kernel/proton-pack.c:568:13: error: no previous prototype for 'spectre_v4_patch_fw_mitigation_enable' [-Werror=missing-prototypes] arch/arm64/kernel/proton-pack.c:588:13: error: no previous prototype for 'smccc_patch_fw_mitigation_conduit' [-Werror=missing-prototypes] arch/arm64/kernel/proton-pack.c:1064:14: error: no previous prototype for 'spectre_bhb_patch_loop_mitigation_enable' [-Werror=missing-prototypes] arch/arm64/kernel/proton-pack.c:1075:14: error: no previous prototype for 'spectre_bhb_patch_fw_mitigation_enabled' [-Werror=missing-prototypes] Add these to asm/spectre.h, which contains related declarations already.

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.
