/*
 *  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.
