Many thanks for all answers. smp_processor_id() works just fine in interrupt context.

Unfortunately /proc/interrupts is not what I was looking for. My idea was to print a line to dmesg at every interrupt to have a timestamp like the following:

[  926.440799] Enter intr at 0
[  926.441059] Exit intr at 0

Every interrupt? You might want to spend some time thinking about which interrupts you don't want to do the above printing for.
