IRQs in /proc/irq/* that aren't listed in /proc/interrupts?

[Chris Friesen]

Hi,

On one of my X86-64 systems /proc/interrupts starts with the following 
interrupts (per-cpu info snipped):

  0:      IR-IO-APIC-edge      timer
   4:      IR-IO-APIC-edge      serial
   8:      IR-IO-APIC-edge      rtc0
   9:      IR-IO-APIC-fasteoi   acpi
  17:      IR-IO-APIC-fasteoi   ehci_hcd:usb1, hpilo


On this same system /proc/irq shows these interrupts:

0
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
17

Is there any way to determine what the interrupts are that aren't listed 
in /proc/interrupts?  Six of them are affined to all CPUs, and I'm 
trying to affine as many interrupts as possible to housekeeping CPUs to 
free up application CPUs for low-latency operations.

I'm not subscribed to the list, so I'd appreciate being CC's on any replies.
