[PATCH 0/2] MR1374: Import MapViewOfFileFromApp and CreateFileMappingFromApp into kernel32

[Santino Mazza (＠tati1454)]

Some programs try to import these functions from kernel32.dll instead of kernelbase.dll

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

On Windows these appear to be forwards, I think it's better to follow that.

[Santino Mazza (＠tati1454)]

For a forward I have to do something like this, right?
```
@ stdcall CreateFileMappingFromApp(long ptr long int64 wstr) KERNELBASE.CreateFileMappingFromApp
```

[Nikolay Sivov (＠nsivov)]

Exactly, with lowercase target module name to match other entries. It's trivial to check if you need a forward or import by comparing procedure addresses. For forwards you'll get same address from GetProcAddress(kernel32) and GetProcAddress(kernelbase). For import they will be different.

[Santino Mazza (＠tati1454)]

Interesting, I wonder if the other imports of MapViewOfFile* and CreateFileMapping* are forwards.
