Linux-2.6.12-rc2v2.6.12-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!

18 * - init
19 * Initialise the kernels jiffy timer source, claim interrupt
20 * using setup_irq. This is called early on during initialisation
21 * while interrupts are still disabled on the local CPU.
22 * - suspend
23 * Suspend the kernel jiffy timer source, if necessary. This
24 * is called with interrupts disabled, after all normal devices
25 * have been suspended. If no action is required, set this to
26 * NULL.
27 * - resume
28 * Resume the kernel jiffy timer source, if necessary. This
29 * is called with interrupts disabled before any normal devices
30 * are resumed. If no action is required, set this to NULL.
31 * - offset
32 * Return the timer offset in microseconds since the last timer
33 * interrupt. Note: this must take account of any unprocessed
34 * timer interrupt which may be pending.
