linux-user: implement reboot syscall
For OBS, we're running a full cross-guest inside of a VM. When a build is done there, we reboot the guest as shutdown mechanism. Unfortunately, reboot is not implemented in linux-user. So this mechanism fails, spilling unpretty warnings. This patch implements sys_reboot() emulation. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
