Hans Petter Selasky d7c5dccd66 Change all kernel C-type macros into static inline functions.
The current kernel C-type macros might obscurely hide the fact that
the input argument might be used multiple times.

This breaks code like:
isalpha(*ptr++)

Use static inline functions instead of macros to fix this.
