Correct, but SUSPEND+SMP select HOTPLUG_CPU, and that results in the trampoline not being discarded. So this must be a !SMP config, and I must have missed a section mismatch warning resulting from acpi_save_state_mem() referencing setup_trampoline() (it's too bad that these warning continue to be suppressed by default). In order to not introduce even uglier CONFIG_X86_64 conditionals, I think the only solution is to revert the whole patch, even though I dislike retaining the trampoline on 32-bits just because it's needed on 64-bits.
