| |
o MODPOST generates warning for i386 if kernel is compiled with CONFIG_RELOCATABLE=y
WARNING: vmlinux - Section mismatch: reference to .init.text:startup_32_smp from .data between 'trampoline_data' (at offset 0xc0519cf8) and 'boot_gdt'
o trampoline code/data can go into init section is CPU hotplug is not enabled.
