Do you mean the patch
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c434b7a6aedfe428ad17cd61b21b125a7b7a29ce
alone ?
I'll try to compile a kernel this way tomorrow, it's a bit late tonight...
Furthermore, please tell me if there are risks that I seriously break let's
say my IDE devices interrupts doing this?
I use EVMS software RAID-5, and I don't want any problem with my RAID-5 set
(I'm just out of some that took me hours...) especially because the EVMS
snapshots I use for performing backups don't work anymore (I mean: are
horribly broke) since I upgraded to a 2.6 series kernel.
This is quite another file, but just to explain that I don't have any recent
and reliable backup these days, not time for me to take any unnecessary risk
with my RAID-5 set until this gets fixed...

Well, that's what I'm worried about ;-))
Anyway, here are the differences I already noticed with and without your two
patches, regarding the way the interrupts are distributed:
1/ Without your patches (from an old note I took) :
[root@totor etc]# cat /proc/interrupts
CPU0
0: 626375 IO-APIC-edge timer
1: 1599 IO-APIC-edge i8042
2: 0 XT-PIC cascade
4: 1708 IO-APIC-edge serial
7: 2 IO-APIC-edge parport0
14: 19858 IO-APIC-edge ide2
15: 5220 IO-APIC-edge ide3
16: 30711 IO-APIC-level nvidia
18: 1799 IO-APIC-level eth0, eth1
19: 103365 IO-APIC-level ide0, ide1, ehci_hcd:usb4, aic7xxx
21: 47273 IO-APIC-level uhci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3
22: 2782 IO-APIC-level VIA8233
(I've removed an SCSI controller and added another 2-channel IDE controller
between the 2 outputs)
2/ With your 2 patches :
