- Rewrite usermode callbacks. These changes should greatly optimize graphic operations. After these changes, my "idle" CPU Usage in taskmgr went from 7-8% to 4-5%, while on the performace page, from 15-18% to 10-13%: * Do not use ugly and messy code to create linked stacks and other such resource-wasting steps. Use our newly implemented 60KB stack support and MmGrowKernelStack when needed. * Write all the low-level code in assembly instead of relying on structures and hodgepodge code. * Add debugging/detection features for invalid calls, such as invalid IRQL, APCs being disabled, invalid previous mode detection (this allowed me to fix the KWAIT_BLOCK bug today). * Finally fix the last (I hope) remaning trap frame bug issue related to V86 mode bias. One of the "hacks" in syscall.S has already been removed and I can now do the promised cleanup. * Allow some failulre cases in callbacks (not all implemented) and extend stack space for future use of SEH in the ntdll dispatcher. * Fix win32k to use callbacks properly: the system fills out *Result and *ResultLength, not the caller. * Use SEH (ProbeForWrite) in callbacks to detect invalid user-mode memory. * Save NPX State and ExceptionList across callbacks (I think this wasn't fully properly done in all cases).
