description:
Add defines for 'passthrough' (PTIOC) ioctl commands. To be used for
devices that use private sets of ioctls (in LKMs), which should not
conflict with other defines. Define a value for each emulation, so
that, for example, Linux binaries which have specific ioctls
redefined to passthrough ones by the compat code, don't conflict
with other emulations.
