New Revision: 25976
URL: http://svn.reactos.org/svn/reactos?rev=25976&view=rev
Log:
- Fix another typo in CommonDispatchException (with yet another critical flaw as a result). Sometimes, exceptions would incorrectly be detected as coming from user-mode even though CS was kernel mode. When creating the KTRAP_FRAME, the kernel would then add the Ring 3 RPL_MASK (3) (because it believed we're in usermode) to the kernel-mode CS, creating the invalid CS of 0xB, which would lead into a GPF during the iretd.
- Re-enable DebugPrint since this now works.
