Subject[PATCH] VGDrvCommonIoCtl: Add f32bit flag argument
Date
On some operating-systems the driver can tell whether an ioctl is a
32bit compat callback or not without looking at the ioctl-nr, at a flag
argument to pass this info along and use it for Linux to not need
separate ioctl codes for 32 and 64 bit.
