These patches enable basic support for booting the x86_64 build on qemu. It's possible to load the bootstrap modules (32-bit for now) but they can't do much yet. This seems more or less in line with the xen port.
Next steps (in no particular order): * test simple syscalls, e.g. mach_tsk_self(), mach_print() * move kernel to higher addresses, even just beyond 4G would be a good start * enhance pmap module to actually use the L4/L3 tables, for now we're limited to the first 8G * fix mig types and test mach_msg() for some rpc. Note that due to recent changes in mig, compilation for x86_64 seems to fail currently, and we should fix mig types for this. To test these patches, you can revert for example to this commit: 63ed32b1 mach_i386: include MACH_I386_IMPORTS I think however it's better to have this part reviewed, and address the mig issues in another round.
