This is to work around the limitations of the buildroot
qemu_nios2_10m50_defconfig which sets the base kernel version for
glibc.

I have no objection. Perhaps you could ask NiosII Maintainers (cc).

If that's needed, so be it. The Linux 3.19 was required because some
obscure ABI change happened at that point.

Doh.. I had cccmd = scripts/get_maintainer.pl --nogit-fallback but of
course as I didn't actually touch an nios2 files it didn't include them.

Thanks.

Title:
  unimplemented thread syscalls in nios2 user-mode emulation

Status in QEMU:
  New

Bug description:
  This bug is reported against the 3.0 release.

  I noticed that the GCC test gcc.dg/torture/tls/tls-test.c is failing
  when run in user-mode qemu for nios2 target.  The problem appears to
  be that the thread-related syscalls are unimplemented in qemu.  Here
  is output from running with -strace:

  Note that set_robust_list and clone are reported as unimplemented.

  I've reported the problems with the signal syscalls separately here.

I also use "git blame" to know who to bother ;)

I don't think so - it's an artefact of the way the buildroot toolchain

I've just build 2.10.2 (with a patch for memfd and this one) and get the
