Use the new arch_loadaddr I/F to align ELF objects to PBVM page
boundaries. For good measure, align all other objects to cache
lines boundaries.
Use the new arch_loadseg I/F to keep track of kernel text and
data so that we can wire as much of it as is possible. It is
the responsibility of the kernel to link critical (read IVT
related) code and data at the front of the respective segment
so that it's covered by TRs before the kernel has a chance to
add more translations.
Use a better way of determining whether we're loading a legacy
kernel or not. We can't check for the presence of the PBVM page
table, because we may have unloaded that kernel and loaded an
older (legacy) kernel after that. Simply use the latest load
address for it.
