It is beyond my area of expertise and Cuper is looking into it, it is in good
hands already ;-)

OTOH the reason I was dabbling into this was to track down tst-getpid2 failure on
ARC as reported in last known reports.

It seems glibc dropped this test and added a new one instead. See commit
0cb313f7cb0e41 ("Fix clone (CLONE_VM) pid/tid reset (BZ#19957)")

I tried copying over tst-clone2 into uClibc (with a hdr include adjustment), but
it seems to runtime fail for me very early (atleast in nSIM).

| [ARCLinux]# ./tst-clone2
| child pid (62) != received pid/tid (0/1606237724)
| parent pid (61) != received pid/tid (0/1606237724)
| [ARCLinux]# random: crng init done
| echo $?
| 2

Can you please double check this for other targets !

I know sucks, lets hope Cuper nails it down quickly.

NP.
