We used to have an iseries specific profiler that used /proc/profile. Now
thats gone we can use the generic timer based stuff.

On PPC64, we keep track of when we need to update jiffies (and the
variables used to calculate the time of day) based on the time base.
If the time base frequence is sufficiently high compared to the
processor clock frequency, then it is possible for the time of day
variables to be corrupted at the time of the first decrementer interrupt
we take. This became obvious on a legacy iSeries where the time base
frequency is the same as the processor clock.
This one line patch fixes the initialisation so that the time of day
variables and the indicator we use to tell when updates are due are
better synchronised.

Use smp_mb and smp_wmb. In particular smp_wmb is lighter weight than wmb.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
