SubjectRe: [PATCH v6 00/27] x86, boot, 64bit: Add support for loading ramdisk and bzImage above 4G
There are obviously good bits to this patchset, but I'm really starting 
to think the "pseudo-linear mode" via a trap handler -- meaning we can
access all of memory without any extra effort -- makes more sense. In
fact, that way we could just build the full page tables without worrying
about incremental bootstrap, depending on if that is a complexity win or
not.

Either way, this is for native only: the Xen domain builder or other
similar entry paths should be setting up page tables that cover all of
memory; I'm hoping Konrad and Stefano can confirm this.

The only reason to go with another approach I can think of is if it
makes 32/64-bit unification cleaner.
