Log:
A long, long time ago in a CVS branch far away (specifically, HEAD prior
to 4.0 and RELENG_3), the BTX mini-kernel used paging rather than flat
mode and clients were limited to a virtual address space of 16 megabytes.
Because of this limitation, boot2 silently masked all physical addresses
in any binaries it loaded so that they were always loaded into the first
16 Meg. Since BTX no longer has this limitation (and hasn't for a long
time), remove the masking from boot2. This allows boot2 to load kernels
larger than about 12 to 14 meg (12 for non-PAE, 14 for PAE).
