This looks very good. Just one suggestion - in order to reduce clutter 
from kernel/kexec.c (as to avoid #ifdefs) perhaps it might be better 
to have crash_save_vmcoreinfo_init() additionally call an arch-specific 
arch_crash_save_vmcoreinfo_init() function and have that append all 
the arch-specific stuff.
