[ Upstream commit 116bfa96a255123ed209da6544f74a4f2eaca5da ]
Compiling with W=1 generates warnings:
CC kernel/bpf/core.o
kernel/bpf/core.c:721:12: warning: no previous prototype for ?bpf_jit_alloc_exec_limit? [-Wmissing-prototypes]
721 | u64 __weak bpf_jit_alloc_exec_limit(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~
kernel/bpf/core.c:757:14: warning: no previous prototype for ?bpf_jit_alloc_exec? [-Wmissing-prototypes]
757 | void *__weak bpf_jit_alloc_exec(unsigned long size)
| ^~~~~~~~~~~~~~~~~~
kernel/bpf/core.c:762:13: warning: no previous prototype for ?bpf_jit_free_exec? [-Wmissing-prototypes]
762 | void __weak bpf_jit_free_exec(void *addr)
| ^~~~~~~~~~~~~~~~~
All three are weak functions that archs can override, provide
proper prototypes for when a new arch provides their own.

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.
