2007-02-17ieee1394: cycle timer read extension for raw1394Pieter Palmers
This implements the simultaneous read of the isochronous cycle timer and the system clock (in usecs). This allows to express the exact receive time of an ISO packet as a system time with microsecond accuracy. http://bugzilla.kernel.org/show_bug.cgi?id=7773 The counterpart patch for libraw1394 can be found at http://thread.gmane.org/gmane.linux.kernel.firewire.devel/8934 Patch update (Stefan R.): Disable preemption and local interrupts. Prevent integer overflow. Add paranoid error checks and kerneldoc to hpsb_read_cycle_timer. Move it to other ieee1394_core high-level API functions. Change comments. Adjust whitespace. Rename struct _raw1394_cycle_timer. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: Pieter Palmers <pieterp@joow.be> Acked-by: Dan Dennedy <dan@dennedy.org>

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!
