Nice article.
May be you would like to add below points as well.
1. Some pointers on context switch when system call is invoked.
2. Data transfer between user and kernel mode in brief.
3. Mention of user mode helper calls in kernel.
I am not sure what scope you have planned though but I think these points will help.
