This is fixed.

This is also fixed.

This is basically done, except the timing code.

Current new bug list:

- 32bit vsyscalls seem to be broken
- 32bit elf coredumps are broken

Required/Wanted features:

- need to coredump 64bit vsyscall code with dwarf2
- move 64bit signal trampolines into vsyscall code and add dwarf2 for it.
- describe kernel assembly with dwarf2 annotations for kgdb (currently waiting
on some binutils changes for this)
