Subject: test/threaded_execve: fix on metag
X-Git-Tag: v4.8~66
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=554e6f3240bcd6110214685371745278b43a8ab7;p=strace

test/threaded_execve: fix on metag

The metag ABI has stacks growing upwards so clone expects the stack
argument to point at the bottom of the stack instead of the top.

* test/threaded_execve.c [__metag__]: Define clone2 differently
to avoid a segfault at runtime.
