This one has me a bit dazed i.g. after looking into the issue
I did find a workaround(keep in mind it's not pretty),
by commenting out set_fixmap_nocache and
(by doing so I was able to load both machines and
execute early debugging in case a problem occurs).

Now as to what might be happening, after going through as
much as I can comprehend the only thing in mind was
reading fixmap.h the comments are stating that vsyscalls
only covers 32bit, and that there needs to be another set
for 64, leading me to believe that this is what I might be hitting.
(my system is pure64, taking in no 32bit at all).

At this point I think I need somebody to give me some info on this,
and if the 64bit issue mentioned above is the case, then we can probably
close this and leave it up to the x86_64 builders to create a 64bit
call for this whenever they get to it.(main thing is I'm able to
run dma early in case of an emergency).
