In my test environment proc-uptime-001 seems to be passing ~40% (N=10)
of the time,
and taking approximately 0.60 seconds  (~11 seconds / 18 tests).

kselftest is not timing individual targets (maybe it should?),
so I don't have a timing history but it used to pass 100% (N=60) of the time.

Thanks, I'll remove it from my tests.

Data for the numbers above:

for X in $(seq 1 10) ; do echo $X && time make TARGETS="proc"
kselftest | grep -P "ok.*proc-uptime-001" ; done
