* the contents of a segment register as second and the contents of
* a *32-bit* general register as third parameter, e.g.
* CTX_SEG_OFF_TO_LIN( context, DS_reg(context), EDX_reg(context) )
* This will generate a linear pointer in all three cases:
* Real-Mode: Seg*16 + LOWORD(Offset)
* 16-bit: convert (Seg, LOWORD(Offset)) to linear
* 32-bit segmented: convert (Seg, Offset) to linear
* 32-bit linear: use Offset as linear address (DeviceIoControl!)
*
* Real-mode is recognized by checking the V86 bit in the flags register,
* 32-bit linear mode is recognized by checking whether 'seg' is
* a system selector (0 counts also as 32-bit segment) and 32-bit
* segmented mode is recognized by checking whether 'seg' is 32-bit
* selector which is neither system selector nor zero.
