- Move from using include guards to pragma once. - Whilst this is non-standard and potentially makes the code less portable, it's supported by both gcc and msvc and should bringg increased compilation speed due to its optimized behaviour (doesn't need to invoke the preprocessor) - Patch by Amine Khaldi [amine.khaldi@reactos.org] svn path=/trunk/; revision=45685 2010-02-26 11:43:19 +00:00			`#pragma once`
stop exporting MmCopyFromCaller and kin and make a local version in the last place we use it, now based on SEH. we'll remove the copy from caller hack from ntoskrnl soon. svn path=/trunk/; revision=16552 2005-07-13 08:48:49 +00:00

probe the pointers in _MmCopyFromCaller and _MmCopyToCaller.
