# 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)
