- The ARM3 PFN database is more of a "shadow" database not to interfere with the real ReactOS PFN database. It starts at 0xB0000000, which is where the initial nonpaged pool started (which now starts somewhere after the ARM3 PFN database).
- No new behavior has been introduced other than additional physical memory consumption for the PFN DB pages, and updated memory layout in the ARM3 world.

- Also set the Page Directory for the system/idle process in a slightly more correct way, instead of depending on the CR3 value. Do this in ARM^3 now, and remove the older code (and the MmGetPageDirectory function, which was only used by this).

- Kill all the requests before closing the socket
- Notify oskittcp when we are cancelling requests so it can properly close the socket

- Much faster and cleaner (will be even faster when System PTE allocation is optimized).
- Better handling of esoteric caching options, especially relevant for ARM.
- Handled through the MiPlatformCacheAttributes, which should be defined differently for each platform (TODO).
- Handles both I/O (device) and RAM physical memory.
- Correct flushing of CPU caches (not a big deal on x86, but matters on ARM).

- We do some minor optimizations to combine chunks if possible after a free, similar to MD Block algorithms in freeldr.c.

- Instead of getting the data from the window station and other strange places, the values are now mostly stored in a global variable. This is possible because NtUserSystemParametersInfo should fail anyway when being called from a non-interactive windowstation (tested on windows XP).
- WM_SETTINGCHANGE is now properly sent not posted to all toplevel Windows also passing the registry string as the lParam value (strings could need some testing).
- SystemMetrics are now set and updated from system parameters.
- Most values are now properly loaded from registry and also saved.
- user32_winetest sysparams: before: 634 executed / 235 failures, after: 1093 executed, 11 failures
- Fixes the non-bold caption font in 2nd stage.
- Implements a number SPI codes.
- Implements helper functions for registry and file access
Thanks to all testers for all the regression testing :)
See issue #4595 for more details.

- First, switch to using system PTEs as it should've been from the beginning. Our original implementation was broken and prone to race conditions, which Dmitry graciously fixed.
- We can now remove the MiZeroPageInternal hack that was used as a way to avoid deadlock/contention in the zero paths.
- Zeroing PTEs is done at DPC level in ReactOS, to avoid ReactOS-specific race issues. In Windows NT, this operation is always done at passive.
- Zeroing PTEs are similar to hyperspace PTEs, but they can be mapped in chunks for optimization.
- ReactOS does not currently make use of this functionality, so zeroing is pretty slow, especially on bootup if you have lots of memory (all RAM is zeroed).
- The existing ReactOS "compatibility layer" for hyperspace was augmented to seamlessly use the new zeroing PTE API.
- You must now unmap zeroing PTEs -- MiZeroPage was modified to do this.
- System PTE binning, NBQUEUES and SLISTS would optimize this further. TBD.
- Once again, tested on the trinity of supported emulators.

- Fix boot.
- The lack of colorful poetry is brought to you by cogent human beings on the West Coast whom you should be thankful haven't gone to bed yet.
