These changes look fine to me.
Just out of curiosity have you tried a Linux kernel build with
these changes installed?
I'm pretty sure that we don't actually use %sys_tick et al.
and instead use %asrNN, but if there is any code out there
depending upon this mis-marked instructions it is better
to find out now rather than later.
