Vladimir Serbinenko d13609a607 Prekernel: Support kernel preloaded at high address ...

Loaders try to put modules as low as reasonable but on
EFI often "reasonable" is much higher than on BIOS. As
a result target can be easily higher than source.

Then we have 2 problems:
* memmove compares virtual address and since target
  is mapped higher it ends up going backwards which
  is wrong if target is physically below source
* order of copying of sections must be inverted if
  target is below source
