[PATCH 0/1] MR2070: ntdll: Add stub for NtQueryInformationProcess( ProcessHandleTable ).

[Paul Gofman (＠gofman)]

Fixes 2K Launcher failure on start (which is using Chromium) with Windows version set to 8.1+ in the prefix (although newer CEF versions don't have Win 7/8.0 fallback here at all).

The failure happens in chromium/sandbox/win/src/win_utils.cc:GetCurrentProcessHandles().

The version which the launcher is using has a Win7 / 8.0 fallback if NtQueryInformationProcess( ProcessHandleTable ) but before going for fallback it asserts that the reported Windows version is less than 8.1 and the process crashes from assert's int3 exception. Newer versions of Chromium don't have Win7/8.0 fallback at all, so going to fail without ProcessHandleTable success regardless of prefix version if hit this path.
