   >     1. Have we tested on QEMU 32-bit and 64-bit? (Normally I attach [NuttX 
Test Logs](https://lupyuen.github.io/articles/pr#testing) to my PRs)
   
   Thanks for reminding, I have attached test log file.
   
   >     2. There's a discussion here on IPI: [Question about RISCV cpu_start 
#11930](https://github.com/apache/nuttx/issues/11930). Wonder if the PR will 
fix this issue? 
   
   No luck, this is another problem. The change on IPI is mainly for using 
different IPI code in different mode.
   
   >     3. Suggest we [squash the 
commits](https://lupyuen.github.io/articles/pr#squash-the-commits) into 1 
commit, so it's easier for other devs to track the history. (Actually I wonder 
if we should have submitted as multiple smaller PRs)
   
   I struggled whether to break this PR into several ones, or just squash them 
as a whole. But finally, I decide to submmit this PR as is. IPI change allows 
to using another change for S mode. dynamic stack allocation make a progress on 
booting with non-zero hart (which is kind of necessary for booting with SBI). 
and SSTC give better performance in S-mode. This three are important for 
qemu-rv S-mode. For the last commit, it is a squash commit. Because I have no 
idea to separate them.
