Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!

* This is our kernel timer structure.

* - init

* using setup_irq. This is called early on during initialisation
* while interrupts are still disabled on the local CPU.
* - suspend
* Suspend the kernel jiffy timer source, if necessary. This
* is called with interrupts disabled, after all normal devices
* have been suspended. If no action is required, set this to
* NULL.
* - resume
* Resume the kernel jiffy timer source, if necessary. This
* is called with interrupts disabled before any normal devices
* are resumed. If no action is required, set this to NULL.
* - offset
* Return the timer offset in microseconds since the last timer
* interrupt. Note: this must take account of any unprocessed
* timer interrupt which may be pending.
