# 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)
#
