* This is the executive's trap table which is installed into the TBR
* register.
*
* NOTE: Unfortunately, this must be aligned on a 4096 byte boundary.
* The GNU tools as of binutils 2.5.2 and gcc 2.7.0 would not
* align an entity to anything greater than a 512 byte boundary.
*
* Because of this, we pull a little bit of a trick. We allocate
* enough memory so we can grab an address on a 4096 byte boundary
* from this area.
