New Revision: 28852
URL: http://svn.reactos.org/svn/reactos?rev=28852&view=rev
Log:
- Use real NT KPCR address (0xFFDFF000).
- Remove all hacked KPCR_BASE definitions.
- Make FreeLDR give address of PageDirectoryStart/End addresses. This was being
ignored/incorrect until now and the page directory could've gotten overwritten.
- Properly setup the HAL PDE, instead of having different PDEs for KUSER_SHARED_DATA, KPCR
and ACPI I/O.
- Do not over-write shared user data with ACPI I/O anymore. This was probably a bad idea.
- Do not mark almost a meg of space as KPCR_USERD_SHARED data anymore, and don't mess
up the CPU TLB anymore.
- Give a dedicated page to KUSER_SHARED_DATA (Page 2, physical address 0x2000) right after
the KPCR, isntead of a random address that probably ended up overwritten later during the
OS's lifetime.
- Fix FS selector in the GDT.
- Remove hack in Trap Fault Handler.
- Add a little hack to allow mapping Page 2 into user-space even though it's marked as
used, this is for the Shared User Data page.
