Murphy <m...@ibm.com> Date: Fri Jan 8 15:43:54 2021 -0600 syscall: ensure openat uses variadic libc wrapper On powerpc64le, this caused a failure in TestUnshareUidGidMapping due to stack corruption which resulted in a bogus execve syscall. Use the existing c wrapper to ensure we respect the ppc abi for variadic functions. Fixes PR go/98610 Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/282717
