About the first few patches in this series in general. I would
re-order them. First fix the tests in kernel32 (so put patch 2 first).
Then move them, but combine this patch with patch 3. Then you can
add new tests.
Some more comments below.

I don't see any reason to dynamically load these fn ptrs, you can just
call the functions directly.

This allocation always fails on Windows see:
https://testbot.winehq.org/JobDetails.pl?Key=53086
So as part of the test fixing before you move them to ntdll, I'd
remove the STATUS_SUCCESS and you'll probably have to add a todo_wine
at the same time.

As mentioned above, this will now call NtVirtualFreeMemory()

I'd probably use NtQuerySystemInformation( SystemCpuInformation, ...) instead.
Huw.
