Max Filippov b6569439f1 xtensa: keep exception/interrupt stack continuous ... Restore original a0 in the kernel exception stack frame. This way it looks like the frame that got interrupt/exception did alloca (copy a0 and a1 spilled under old stack to the new location as well) to save registers and then did a call to handler. The point where interrupt/exception was taken is not in the stack chain, only in pt_regs (call4 from that address can be simulated to keep it in the stack trace).
