[PATCH] ARC: prevent showing irrelevant exception info in signal message

2019-01-21 Thread Eugeniy Paltsev
We process signals in the end of syscall/exception handler. If the signal is fatal we print register's content using show_regs function. show_regs() also prints information about last exception happened. In case of multicore system we can catch the situation when we will print wrong information ab
