[PATCH 1/7] compat: add struct compat_ifreq etc to compat.h

From: Arnd Bergmann
Date: Fri Nov 06 2009 - 13:10:51 EST


In order to move socket ioctl conversion code into multiple
places in the socket code, we need a common defintion of
the data structures it uses.

Also change the name from ifreq32 to compat_ifreq to
follow the naming convention for compat.h
