pmdalinux: dynamic per-CPU and per-node instance domains
Convert the Linux kernel PMDA per-CPU and per-NUMA-node indoms
to using the pmdaCache routines, so the PMDA behaves correctly
with these system changes.
This commit also makes some other closely related improvements.
The disk.* refresh logic at pmFetch time is optimised so as to
not cause unnecessary /proc/stat rescanning. Logic determining
machine type is moved out of the cpu_name routine into a more
appropriate place, and implemented using uname(2) as a fallback
instead of simply "linux" on non-SGI-NUMA machines.
