There were no comments on the RFC so reposting as a final patch. Changes since v5: - Removed RFC
Changes since v4: - Split into a seperate submission to simplify review - Use load/store atomic functions as suggested by Richard Henderson - Do 8, 4, 2 byte atomic ldst for sizes smaller than 16 bytes This patch now uses the atomic ldst functions from accel/tcg/ldst_atomicity.c.inc to ensure element size atomicity. I was not sure of the best way to make these functions accessible from the riscv target, so any suggestions are very welcome.
