From: Keir Fraser Date: Tue, 15 Apr 2008 09:21:17 +0000 (+0100) Subject: [IA64] Fix pci.h include overlap X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14215^2~193 X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=d354d1ec9459f2ee534ed6fbdf178f644a313a09;p=xen.git [IA64] Fix pci.h include overlap The new upstream xen/pci.h has a name conflict with our modified linux/pci.h and shows up earlier in the include search path. Since our usage of linux/pci.h is limited, rename to linux/linux-pci.h to avoid duplicate names and cleanup the few users.
