[ion] 23880: - More Initialization changes: - Initialize bugcheck lists, timer DPC, profile list/locks, timer lists, the swap lists and syscall table as part of KiInitSystem (portable). - Add more initialization for the initial/idle process+thread (some code disabled due to dispatcher problems). - Add code to support future Timer implementation (based on tick-hashes) - Separate post-boostrap initialization code in KiInitializeKernel. - Add some support for future SMP paths. - Create a DPC stack.

New Revision: 23880
URL: http://svn.reactos.org/svn/reactos?rev=23880&view=rev
Log:
- More Initialization changes:
- Initialize bugcheck lists, timer DPC, profile list/locks, timer lists, the swap lists
and syscall table as part of KiInitSystem (portable).
- Add more initialization for the initial/idle process+thread (some code disabled due
to dispatcher problems).
- Add code to support future Timer implementation (based on tick-hashes)
- Separate post-boostrap initialization code in KiInitializeKernel.
- Add some support for future SMP paths.
- Create a DPC stack.
- Changes based on WI4 and my automated parsing tool.
