This applied cleanly for me, and I was able to get the software to
build.  There is something wrong with the real-time code, however, as
it crashes/hangs on the first line of the lat.hal latency test.

More specifically, the second time through hal_init, the code seems to
be waiting forever to acquire hal_data->mutex via rtapi_mutex_get

I did crawl through the code resulting from your patches, the original
patch set, and my working 2.4.4-rt code from bitmuster.  There were
only two minor issues I saw.  One was a space/tab whitespace change,
and the other was disabling the building of several HAL modules which
I assumed was intentional.

So I suspect the issue is not related to the application of the
linux-rt patch, but to the linuxcnc code changes between 2.4.4 and
HEAD.  If I can figure out why the hal_data->mutex isn't getting
released properly, I'll let you know.
