What is 'TLB'? I'm not aware of any vector which is named TLB.

Add metricfs support for displaying percpu irq counters for x86.
The top directory is /sys/kernel/debug/metricfs/irq_x86.
Then there is a subdirectory for each x86-specific irq counter.
For example:
cat /sys/kernel/debug/met

How is that related to core? The x86 subsys prefix is 'x86' and for this
particular thing it's 'x86/irq:'. That applies to the rest of the series
as well.
