 114  *       parameters, interrupt handlers should use CTX_SEG_OFF_TO_LIN with
 115  *       the contents of a segement register as second and the contents of
 116  *       a *32-bit* general register as third parameter, e.g.
 117  *          CTX_SEG_OFF_TO_LIN( context, DS_reg(context), EDX_reg(context) )
 118  *       This will generate a linear pointer in all three cases:
 119  *         Real-Mode:   Seg*16 + LOWORD(Offset) + V86BASE
 120  *         16-bit:      convert (Seg, LOWORD(Offset)) to linear
 121  *         32-bit:      use Offset as linear address (DeviceIoControl!)
 122  *
 123  *       Real-mode is recognized by checking the V86 bit in the flags register,
 124  *       32-bit mode is recognized by checking whether 'seg' is a system selector
 125  *       (0 counts also as 32-bit segment).
