for the common HZ=100, 250 or 1000 cases, only inlining them
for odd HZ values like HZ=300.
The inlining overhead showed up in performance tests of the TCP code.
(Marked as an RFC pull request, as it's not a regression.)

Pull timer fix from Ingo Molnar:
"Improve the inlining of jiffies_to_msecs() and jiffies_to_usecs(), for
the common HZ=100, 250 or 1000 cases. Only use a function call for odd
HZ values like HZ=300 that generate more code.
The function call overhead showed up in performance tests of the TCP
code"
