+ * scans linux style /proc tables, e.g. :
+ *
+ * numa_hit 266809
+ * numa_miss 0
+ * numa_foreign 0
+ * interleave_hit 0
+ * local_node 265680
+ * other_node 1129
+ *
+ * Value is a counter that wraps at maxval,
+ * unless maxval is 0, in which case the 
+ * value is treated as instantaneous and no
+ * wrap detection is attempted.
+ *
+ * Tables are typically declared as a static array, and
+ * then allocated dynamically with linux_table_clone().
+ * e.g. :
+ *
+ *	static struct linux_table numa_meminfo_table[] = {
+ *	    { "numa_hit",		0xffffffffffffffff },
+ *	    { "numa_miss",		0xffffffffffffffff },
+ *	    { "numa_foreign",		0xffffffffffffffff },
+ *	    { "interleave_hit",		0xffffffffffffffff },
+ *	    { "local_node",		0xffffffffffffffff },
+ *	    { "other_node",		0xffffffffffffffff },
