[Qemu-devel] [PATCH 2/6] mips: missing syscall returns wrong errno

[Wesley W. Terpstra]

Return -TARGET_ENOSYS instead of -ENOSYS from linux-user/main.c
   * Caused strange 'Level 2 synchronization messages' instead of
correctly reporting the syscall was missing.
   * Made glibc simply fail instead of using older syscalls
