Firstly it breaks MSVC builds, secondly the stuff doesn't belong into this header. MS headers don't have __fpclassify etc and our headers are not supposed to contain any fancy additions. If you need it for 3rd party code, put it somewhere else.

Author: ion Date: Wed Aug 1 07:54:37 2012 New Revision: 57011 URL: http://svn.reactos.org/svn/reactos?rev=57011&view=rev Log: [NTOSKRNL]: Implement last bits of session space support (minus session pool). Processes now have a ->Session pointer! Implement and enable MmSessionId in a bunch of places. [NTOSKRNL]: Set MiSessionSpaceWs address and use where needed. [NTOSKRNL]: Initialize the session working set, and add support to MiLockWorkingSet and MiUnlockWorkingSet for session WS. [NTOSKRNL]: Implement MiSessionAddProcess and MiSessionRemoveProcess which does the work required for this. [NTOSKRNL]: Fix IoGetIrpRequestorProcess. In my private branch, MmMapViewInSessionSpace is working fine for the user and GDI heaps. Will enable after TestBot tests.
