Doug Rabson 1ebcad5720 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.

* According to ANSI (section 2.2.4.2), the values below must be usable by
* #if preprocessing directives. Additionally, the expression must have the
* same type as would an expression that is an object of the corresponding
* type converted according to the integral promotions. The subtraction for
* INT_MIN and LONG_MIN is so the value is not unsigned; 2147483648 is an
* unsigned int for 32-bit two's complement ANSI compilers (section 3.1.3.2).
* These numbers work for pcc as well. The UINT_MAX and ULONG_MAX values
* are written as hex so that GCC will be quiet about large integer constants.
