麻烦哪位高手看一下。
WARNING: vmlinux.o(.text+0x6962): Section mismatch in reference from the function setup_trampoline() to the variable .cpuinit.data:trampoline_end
The function setup_trampoline() references
the variable __cpuinitdata trampoline_end.
This is often because setup_trampoline lacks a __cpuinitdata
annotation or the annotation of trampoline_end is wrong.

WARNING: vmlinux.o(.text+0x6968): Section mismatch in reference from the function setup_trampoline() to the variable .cpuinit.data:trampoline_data
The function setup_trampoline() references
the variable __cpuinitdata trampoline_data.
This is often because setup_trampoline lacks a __cpuinitdata
annotation or the annotation of trampoline_data is wrong.

WARNING: vmlinux.o(.text+0x6975): Section mismatch in reference from the function setup_trampoline() to the variable .cpuinit.data:trampoline_data
The function setup_trampoline() references
the variable __cpuinitdata trampoline_data.
This is often because setup_trampoline lacks a __cpuinitdata
annotation or the annotation of trampoline_data is wrong.

WARNING: vmlinux.o(.cpuinit.data+0x0): Section mismatch in reference from the variable initial_code to the function .init.text:i386_start_kernel()
The variable __cpuinitdata initial_code references
a function __init i386_start_kernel().
If i386_start_kernel is only used by initial_code then
annotate i386_start_kernel with a matching annotation.

WARNING: vmlinux.o(.cpuinit.data+0xf30): Section mismatch in reference from the variable trampoline_data to the variable .init.text:startup_32_smp
The variable __cpuinitdata trampoline_data references
a variable __init startup_32_smp.
If startup_32_smp is only used by trampoline_data then
annotate startup_32_smp with a matching annotation.
