Log:
[SMSS2]: Implement SmpCallCsrCreateProcess and SmpLoadSubsystem. We now load CSRSS and
everything works 100%! Winlogon is now launched by SMSS2 and no regressions have been
found.
[SMSS]: Turn off all code other than setting up the pagefile.
There's a lot of debug prints, as soon as things seem stable after a few days, SMSS
will be gone and SMSS2 will take over and DPRINT1s will mostly be gone.
