[Qemu-devel] [PULL 14/24] cpus.c: Use pthread_sigmask() rather than sigprocmask() |

From: Peter Maydell <address@hidden>
On Linux, sigprocmask() and pthread_sigmask() are in practice the
same thing (they only set the signal mask for the calling thread),
but the documentation states that the behaviour of sigprocmask() in a
multithreaded process is undefined. Use pthread_sigmask() instead
(which is what we do in almost all places in QEMU that alter the
signal mask already).
