31  * (Errnos are host errnos; we rely on QEMU_ERESTARTSYS not clashing
32  * with any of the host errno values.)
68  * Here it is important that the host syscall is made
69  * via this safe_syscall() function, and *not* via the host libc.
70  * If the host libc is used then the implementation will appear to work
72  * signal could arrive just before we make the host syscall inside libc,
79  * (If the implementation needs to make multiple host syscalls this is
82  * stay in the host kernel indefinitely) it's OK to use libc if necessary.
92  * The basic setup is that we make the host syscall via a known
93  * section of host native assembly. If a signal occurs, our signal
94  * handler checks the interrupted host PC against the address of that
104  * (1) signal came in just before we took the host syscall (a race);
109  * (2) signal came in while the host syscall was blocking, and the
110  *   host kernel decided the syscall should be restarted;
115  * host syscall was blocking, and the host kernel decided that the syscall
116  * should not be restarted; in this case QEMU's host signal handler will
