Log:
SVN rev 220281 on 2011-04-02 16:02:25Z by kib
Implement compat32 shims for PCIOCGETCONF.
There is a generic problem with the shims for ioctls that receive
pointers to the usermode data areas in the data argument. We either have
to modify the handler to accept UIO_USERSPACE/UIO_SYSSPACE indicator, or
allocate and fill a usermode memory for data buffer in the host format.
The change goes the second route, in particular because we do not need
to modify the handler.
