Commit:8205bc1 ("target/riscv: introduce ssp and enabling controls for zicfiss") introduced CSR_SSP but it mis-interpreted the spec on access to CSR_SSP in M-mode.

Shadow Stack Pointer (ssp) CSR access contr" in the priv spec.Fixes: 8205bc127a83 ("target/riscv: introduce ssp and enabling controls for zicfiss". Thanks to Adam Zabrocki for bringing this to attention.
Is this patchset (including "[2/2] target/riscv: fixes a bug against `ssamoswap` behavior in M-mode") applicable for stable qemu series? Thanks, /mjt
