* These ioctls were versioned after NetBSD 8.x.

* RAIDFRAME_FAIL_DISK had unused pointers removed from the structure.
* RAIDFRAME_CHECK_*EXT and RAIDFRAME_GET_COMPONENT_LABEL were converted
* from pointers to full structures so that ioctl framework does the copyout.
* RAIDFRAME_GET_INFO80 had the containing structure reorganised so that
* the layout became bitsize neutral.
*
* These 6 changes enable COMPAT_NETBSD32 support to work sanely with
* these ioctls, leaving only RAIDFRAME_CONFIGURE needing extra help.
