New Revision: 41824
URL: http://svn.reactos.org/svn/reactos?rev=41824&view=rev
Log:
- Fix a critical bug in the German hack which was causing the last PDE not to be synched
with the ReactOS Memory Manager (or worse, the first, if there was only one PDE).
- Add a new file which will hold the executive layer above the pool allocator (the Ex*
routines).
- This should eventually be moved to \ex.
- Note that the current ReactOS pool Ex* routines are in \mm, which is dead wrong.
- Define the POOL_DESCRIPTOR and POOL_HEADER structures for the NT 5.2 pool.
- Define, create, and implement the routine to initialize a pool vector.
- For now, we assume you want the nonpaged pool vector/descriptor.
- Call this routine from the ARM3 initialization routine.
- No changes to system behavior other than the bugfix above.
