The default kernel should always be the compatible with as much as=20
possible.  Disabling PHYS_64BIT by default means that the default kernel=20
will not work with a 36-bit DTS.  If you attempt to boot such a kernel=20
with a 36-bit DTS, there will be no text output.  Most people will not=20
know why it's not working.

So the safest option is for PHYS_64BIT to be enabled by default.  That=20
way, the kernel will always work.
