Removed my name from the hall of fame. Since it seems, that parts of ReactOS are implemented by ripping code from Windows, it isn't longer honourable to find my name inside the sources of ReactOS.

[ion] 20942: - Use MmUserProbeAddress in the system call handler to verify the parametes we got from user-mode are valid and return STATUS_ACCESS_VIOLATION if the check fails.
by ion＠svn.reactos.org 17 Jan '06

- Use MmUserProbeAddress in the system call handler to verify the parametes we got from user-mode are valid and return STATUS_ACCESS_VIOLATION if the check fails. - Handle failure after PsConvertToGuiThread and return STATUS_INVALID_SYSTEM_SERVICE and/or FALSE and/or -1 on failure. - Made MCE/XMMI interrupts unexpected on-boot. - Removed KiTrapUnknown and used KiTrap0F (15) instead, which is the generic unexpected handler.
