- Implement DbgkpConvertKernelToUserStateChange. I just remembered that there's actually 3 debug subsystems in NT: Win32, Native and Kernel, so this structure will still need to be heavily parsed at the Win32 level (in kernel32) before user-mode debuggers can work (so I'll have to write a small native-mode debugger test app to test this implementation first).
- Implement DbgkpMarkProcessPeb. svn path=/trunk/; revision=24577
