Subjectsys_ioctl export consolidation
Since we noted that sys_ioctl is not currently being exported for ia64
to be used in the 32-bit emulation routines I'd like to suggest the
following patch, which, instead of making this available in another
individual architecture, exports the symbol whenever CONFIG_COMPAT is
defined (legal users should be a subset of
[un]register_ioctl32_conversion users, which is scoped by the same
config option).

Regards, Jan
