Haven't done that yet, but I have checked all of the reported failures.

time-hrtimer:-Use-softirq-based-wakeups-for-non-RT-threads.patch fixes
clock_settime_8-1.run-test,Âhrtimer:-Update-offset-for-soft-bases.patch
fixes the rest.

However...

homer:..debug/tracing # /usr/local/ltp/conformance/interfaces/clock_settime/clock_settime_8-1.run-test
Test PASSED
homer:..debug/tracing # chrt -f 1 /usr/local/ltp/conformance/interfaces/clock_settime/clock_settime_8-1.run-test
Ended too late. 1507308976 >> 1507308974
Test FAILED

That's a bit troubling. ÂNo earlier kernel, rt or not, cares about
policy. ÂEither now getting a NAK is less than wonderful, but
SCHED_FIFO gets a NAK while SCHED_OTHER walks away with an ACK?
