I only looked at the Section mismatch warnings.
They are fixed by following patch.
James - I assume you will take this forward?

[PATCH] i386/voyager: fix section mismatch warnings
> WARNING: vmlinux.o(.text+0xeaf7): Section mismatch: reference to .init.text:init_gdt (between 'voyager_smp_prepare_boot_cpu' and 'smp_vic_cmn_interrupt')
voyager_smp_prepare_boot_cpu is marked __devinit and calls init_gdt.
init_gdt is marked __cpuinit
Fix seems to make voyager_smp_prepare_boot_cpu __init since I cannot see that
function being used for HOTPLUG. Maybe HOTPLUG_CPU but not HOTPLUG.

voyager_cat_init is used only by smp_boot_cpus that is marked __init.
So fix is to mark voyager_cat_init as __init
