190 * parameters, interrupt handlers should use CTX_SEG_OFF_TO_LIN with
191 * the contents of a segement register as second and the contents of
192 * a *32-bit* general register as third parameter, e.g.
193 * CTX_SEG_OFF_TO_LIN( context, DS_reg(context), EDX_reg(context) )
194 * This will generate a linear pointer in all three cases:
195 * Real-Mode: Seg*16 + LOWORD(Offset) + V86BASE
196 * 16-bit: convert (Seg, LOWORD(Offset)) to linear
197 * 32-bit: use Offset as linear address (DeviceIoControl!)
198 *
199 * Real-mode is recognized by checking the V86 bit in the flags register,
200 * 32-bit mode is recognized by checking whether 'seg' is a system selector
201 * (0 counts also as 32-bit segment).
