We setup APIC vectors for threshold errors if interrupt_capable. However, we don't set interrupt_enable by default. Rework threshold_restart_bank() so that when we set up lvt_offset, we also set IntType to APIC and also enable thresholding interrupts for banks which support it by default. User is still allowed to disable interrupts through sysfs. While at it, check if status is valid before we proceed to log error using mce_log. This is because, in multi-node platforms, only the NBC (Node Base Core, i.e. the first core in the node) has valid status info in its MCA registers. So, the decoding of status values on the non-NBC leads to noise on kernel logs like so: EDAC DEBUG: amd64_inject_write_store: section=0x80000000 word_bits=0x10020001 [Hardware Error]: Corrected error, no action required.
