Subject: mips: missing syscall returns wrong errno
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7c2f6157d833cb95b355c7321597bc5a5ac976e4;p=qemu.git

mips: missing syscall returns wrong errno

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
