+# name meta args...
+# Where meta contains a string of variants to generate.
+# Upper-case implies _{acquire,release,relaxed} variants.
+# Valid meta values are:
+# * B/b - bool: returns bool
+# * v - void: returns void
+# * I/i - int: returns base type
+# * R - return: returns base type (has _return variants)
+# * F/f - fetch: returns base type (has fetch_ variants)
+# * l - load: returns base type (has _acquire order variant)
+# * s - store: returns void (has _release order variant)
+# Where args contains list of type[:name], where type is:
+# * cv - const pointer to atomic base type (atomic_t/atomic64_t/atomic_long_t)
+# * v - pointer to atomic base type (atomic_t/atomic64_t/atomic_long_t)
+# * i - base type (int/s64/long)
+# * p - pointer to base type (int/s64/long)
