Provide a real fix to the too-many-translations problem when booting
from CD on 64-bit hardware to replace existing band-aids. This occurred when the preloaded mdroot required too many mappings for the static buffer. Since we only use the translations buffer once, allocate a dynamic buffer on the stack. This early in the boot process, the call chain is quite short and we can be assured of having sufficient stack space. Reviewed by: grehan
