This patch adds support for compat ioctl from 32 bits userland to
Qualcomm fastrpc driver.
Supported ioctls in this change are INIT, INVOKE, and ALLOC/FREE_DMA.
Most of the work is derived from various downstream Qualcomm kernels.
Credits to various Qualcomm authors who have contributed to this code.

Can't you just define the native ioctls so that you don't need this.
There are long time defined structures that are passed as argument to
these ioctls and their sizes vary between 32 and 64 bits userlands, so
the ioctl command values.
Unless I'm missing something here this also has the advantage not to be
compiled if CONFIG_COMPAT is not set.

Thierry
