Subject: [PATCH 5/9] ppc32: Modify Freescale MPC52xx IRQ mapping to _not_ use irq 0
Date: Tue, 20 Dec 2005 21:42:33 +0100 (CET) [thread overview]

ppc32: Modify Freescale MPC52xx IRQ mapping to _not_ use irq 0
AFAIK IRQ number 0 is a perfectly valid IRQ number. But it seems there
are numerous places where it's considered to be invalid or "no irq" value.
Since that value is problematic, the IRQ mapping is changed to not
use it.
