Mattias Rönnblom Sept. 9, 2024, 2:57 p.m. UTC 
Have rte_bit_[test|set|clear|assign|flip]() and rte_bit_atomic_*()
handle volatile-marked pointers.

PATCH v3:
 * Updated to reflect removed 'fun' parameter in __RTE_GEN_BIT_*()
   (Jack Bond-Preston).

PATCH v2:
 * Actually run the test_bit_atomic_v_access*() test functions.
