Warning messages: WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x2b6a): Section mismatch in reference from the function setup_trampoline() to the variable .init.data:trampoline_data The function __cpuinit setup_trampoline() references a variable __initdata trampoline_data. If trampoline_data is only used by setup_trampoline then annotate trampoline_data with a matching annotation. WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x2b71): Section mismatch in reference from the function setup_trampoline() to the variable .init.data:trampoline_end The function __cpuinit setup_trampoline() references a variable __initdata trampoline_end. If trampoline_end is only used by setup_trampoline then annotate trampoline_end with a matching annotation.
