[Qemu-devel] ia64 support

[Aurelien Jarno]

This patch series adds host Itanium support to QEMU.

System mode works correctly except a few unaligned access in the slirp
code (fixed by the kernel). It has been tested by booting debian 
installer on arm, i386, mips, mipsel, ppc, sparc, and x86_64. A full 
installation has been done on sparc.

User mode works correctly for static binaries, but fails for some
dynamic binaries, due to mmap emulation not working correctly when
host page size is bigger than the target one.
