mm/damon/sysfs: support the physical address space monitoring
This commit makes DAMON sysfs interface supports the physical address
space monitoring. Specifically, this commit adds support of the initial
monitoring regions set feature by adding 'regions' directory under each
target directory and makes context operations file to receive 'paddr' in
addition to 'vaddr'.
As a result, the files hierarchy becomes as below:
/sys/kernel/mm/damon/admin
│ kdamonds/nr_kdamonds
│ │ 0/state,pid
│ │ │ contexts/nr_contexts
│ │ │ │ 0/operations
│ │ │ │ │ monitoring_attrs/
│ │ │ │ │ │ intervals/sample_us,aggr_us,update_us
│ │ │ │ │ │ nr_regions/min,max
│ │ │ │ │ targets/nr_targets
│ │ │ │ │ │ 0/pid_target
│ │ │ │ │ │ │ regions/nr_regions <- NEW DIRECTORY
│ │ │ │ │ │ │ │ 0/start,end
│ │ │ │ │ │ │ │ ...
│ │ │ │ │ │ ...
│ │ │ │ ...
