 == Ztso atomics mappings
 
 This specifies additional mappings of C and C\++ atomic operations to RISC-V
-machine instructions. Other languages, for example Java, provide similar
-facilities that should be implemented in a consistent manner, usually

+machine instructions.
 
 For each construct, we provide a mapping that assumes only the A and Ztso
 extension.
 
 All mappings interoperate correctly with the RVWMO mappings, and with the
 original "Table A.6" mappings.

-address mappings for read-modify-write operations like `fetch_add`, and
-`exchange`. The second section deals with operations that have direct
-`amo` instruction equivalents in the RISC-V A extension. The final
