Summary: provide a stub for ntdll.NtSystemDebugControl()
(Ollydbg 2.x)
Product: Wine
Version: 1.2-rc5
Platform: x86
URL: http://www.ollydbg.de/version2.html
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2

Hello,
a simple one...
Ollydbg 2.x uses NtSystemDebugControl( DebugSysReadVirtual, ...) to read kernel
memory (driver/OS address space) for informational purposes.
Failure to do so doesn't cause harm.
Although this approach doesn’t require any additional kernel driver (only the
SeDebugPrivilege privilege on the running process) it's only useful for Windows
XP systems. It's disallowed since Windows Vista/Windows 7.
Not really useful in Wine but it obviously needs a stub.

Dump params and return STATUS_NOT_IMPLEMENTED to keep it running ;-)
