New Revision: 23894
URL: http://svn.reactos.org/svn/reactos?rev=23894&view=rev
Log:
- Fix KTSS definition.
- Add GetSegment inlines (ie: GetSs, GetDs, etc)
- Fix up definition of KiBootGdt to use KGDTENTRY instead of USHORT. Also define
KiGdtDescriptor using KDESCRIPTOR.
- Remove GDT initialization code completely. The GDT is already initialized on boot.
- Remove tss.c and add KiInitializeTss(2) to setup a TSS and proper IOPM/Interrupt
Direction map settings for V86/VDM.
- Copy the TSS code over but prettyify it to use NT/NDK structures instead of ugly USHORT
typecasts.
