Max Filippov fd5924d8b3 xtensa: ISS: don't hang if stdin EOF is reached ... commit 362014c8d9d51d504c167c44ac280169457732be upstream. Simulator stdin may be connected to a file, when its end is reached kernel hangs in infinite loop inside rs_poll, because simc_poll always signals that descriptor 0 is readable and simc_read always returns 0. Check simc_read return value and exit loop if it's not positive. Also don't rewind polling timer if it's zero.
