| | | | | | | | | | | | | | | | | | | | | | We were comparing {bus,devfn} and assuming that a match meant it was the same device. It doesn't -- the same {bus,devfn} can exist in multiple PCI domains.

Not just the bridge itself. This fixes the device_to_iommu() function accordingly. (It's broken if you have the same PCI bus numbers in multiple domains, but this function was always broken in that way; I'll be dealing with that later).

This patch fixes it by introducing a __hrtimer_start_range_ns() method that will not use raise_softirq_irqoff() but __raise_softirq_irqoff() which avoids the wakeup. It then also changes schedule() to check for pending softirqs and do the wakeup then, I'm not quite sure I like this last bit, nor am I convinced its really needed.

However, the actual format had been binary, not text. This restores the original binary format, while also adding an origin CPU field (since ftrace doesn't expose the data per-CPU to userspace), and re-adding the timestamp field. It also drops arch-independent field sizing where it didn't make sense, so pointers won't always be 64 bits wide like they used to.

This patch allows tracing within slab headers' inline functions.
