Yes, that was Sridhar Samudrala <sri@us.ibm.com>.  I've done some work
to create an accurate implementation of msecs_to_jiffies() and jiffies_to_msecs(),
which I was going to submit later this week after clearing it with George Anziger.
[I have a follow-on patch that reworks the select/poll/epoll timeout fixes
to use timeval_to_jiffies() and msecs_to_jiffies().]

The attached patch combines Sridhar's consolidation patch with my
more accurate routines in the spirit of the rest of time.h.  It is against
2.6.6-rc3-bk3.  Feedback welcome.  I'm happy to rediff against latest kernel,
I just haven't had time the last few days.

George's userland test harness was used to test this on x86 and x86_64.
Below are excerpts from my test output for powers of 2.

The kernel patch compiles and boots on x86, but hasn't been tested extensively.
