New Revision: 25965
URL: http://svn.reactos.org/svn/reactos?rev=25965&view=rev
Log:
- Remove KD APIs from stub HAL, they've been in kdcom for a while (merge from
kd-branch).
- DebugPrint/DebugPrompt should have an int3 after the int2d, and the int2d handler should
++ the trap frame's EIP to compensate (merge from kd-branch).
- Remove KDB symbol hooks (merge from kd-branch).
- Make PSEH compialble in MSVC again after Greatlord's break.
- Fix KiSaveProcessorControlState/KiRestoreProcessorControlState (merge from kd-branch).
- Disable GDB hook/hacks (merge from kd-branch).
- Add KD64 directory from kd-branch with SharedUserData access enabled (no other code
changed). It's not currently compiled though, just putting it here.
