Each call to get_cpu_rev() leads to repetitive execution of code to detect the cpu revision.
This patchset ensures that mechanism to detect revision is not executed each time; instead a stored value is returned.
Since, revision info is needed in s_init(), the function to identify cpu revision needs to be called twice. At the moment, it is necessary/ unavoidable.
