I looked at there are two things together. Header cleanup and syscall cleanup.
For both I have problems.
1. header cleanup -> some of them is only moving to generic location -> that's no problem
2. header cleanup -> some of them is pain because I have to recompile toolchain
that's should be a big deal but after recompilation kernel, user apps I am getting some problems.
3. syscall cleanup -> we still have old libc and I can't simple remove ancient syscalls

I would like to test all of them but I can't do too fast.
I am trying to cleanup uaccess.h troubles and I have some changes about context switch change
but this work only on MMU and I haven't had a time to fix it on noMMU.
I am fighting with old code where I don't have any information about.

I have your changes in my queue and they inspired me to do things better and I hope that
I will be able to use all of them.
