CPU 0(0x80) is reported here:

the intent is to print the CPU the thread is running on, and the cpuset it's allowed to run on. In your case, it may be that sched_getcpu isn't returning the correct result, or the API has changed since stressapptest was written.

The "bus address" is the physical address as viewed by the CPU, via https://www.kernel.org/doc/Documentation/vm/pagemap.txt, although there are a number of things that could be considered a "physical address" depending on the system.

Dear sir , 
            This is my error log .  
            I want to know why CPU 0 has 0x80 , 0x10 , 0x40  , 3 types .
            I know the core_id use gnu sched_getcpu() but why CPU 0 isn't equal 0x1 ??
            And how do i get physical address of errors  , it seems to be bus address?(uint64 paddr; // This is the bus address, if available.)
Many thanks ,
Victor
