WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x347): Section mismatch in reference from the function fpu_init() to the function .init.text:init_thread_xstate()Thanks and regards.
The function __cpuinit fpu_init() references
a function __init init_thread_xstate().
If init_thread_xstate is only used by fpu_init then
annotate init_thread_xstate with a matching annotation.
WARNING: kernel/built-in.o(.text+0x10690): Section mismatch in reference from the function notify_cpu_starting() to the variable .cpuinit.data:cpu_chain
The function notify_cpu_starting() references
the variable __cpuinitdata cpu_chain.
This is often because notify_cpu_starting lacks a __cpuinitdata
annotation or the annotation of cpu_chain is wrong.
WARNING: vmlinux.o(.text+0x33264): Section mismatch in reference from the function notify_cpu_starting() to the variable .cpuinit.data:cpu_chain
The function notify_cpu_starting() references
the variable __cpuinitdata cpu_chain.
This is often because notify_cpu_starting lacks a __cpuinitdata
annotation or the annotation of cpu_chain is wrong.
