[ Upstream commit 12879bda3c2a974b7e4fe199a9c21f0c5f6bca04 ] WARNING: vmlinux.o(.text+0x2366): Section mismatch in reference from the function csky_start_secondary() to the function .init.text:init_fpu() The function csky_start_secondary() references the function __init init_fpu(). This is often because csky_start_secondary lacks a __init annotation or the annotation of init_fpu is wrong.
