Subject: [PATCH 2/2] x86-64: change the size for interrupt array to NR_VECTORS
Date: Fri, 24 Nov 2006 17:36:59 -0800	[thread overview]
Message-ID: <86802c440611241736l545ddf33i3bb08f3cd6446b14@mail.gmail.com> (raw)

Please check the patch.

[-- Attachment #2: i8259.patch --]
[-- Type: text/x-patch, Size: 869 bytes --]

[PATCH] x86_64: interrupt array size should be aligned to NR_VECTORS
interrupt array is referred for idt vectors instead of NR_IRQS, so change size
to NR_VECTORS - FIRST_EXTERNAL_VECTOR. Also change to static.
