+RISC-V: Cannot set SEIP bit of mip csr register in M mode
+Description of problem:
+
+Steps to reproduce:
+1.   run assembly instructions **in M mode**: 
+```
+not t0, x0    // set t0 to 0b11..11
+csrs mip, t0  // write mip with t0, mip registers are WARL(Write Any Values, Reads Legal Values)
+csrr t1, mip  // read value from mip to t1
+```
+2.   GDB enters the command `display/z $t1` to see that the content of the t1 register is 0x466, which means that the SEIP bit of mip is not set.
+3.   According to page 47 of [riscv-privileged-20211203](https://github.com/riscv/riscv-isa-manual/releases/download/Priv-v1.12/riscv-privileged-20211203.pdf), `SEIP is writable in mip`.
+4.   According to page 81 of the same manual,`If implemented, SEIP is read-only in sip`.
+5.   However, the above code and results show that the SEIP bit of mip cannot be set by software **in M mode**.
