Suggestions on Avoiding syscall Overhead

I'd like to give some feature requests on this. I think it will not
increase your work load so much however it will benifit the FreeBSD a
lot.

We can have 3 type of pages mapped into one process's address map.
1. System wide global readonly page which will help on these syscalls:
    gethostname,getdomainname,uname
    help on importing sysenter as syscall entry point!!

2. Per process Readonly page. (change will still through standard syscall)
    help on the syscalls:
    getuid, geteuid, getpid,getgid, getegid, getpgrp,

3. As you planed, Read+Write Page
