From: Greg Kroah-Hartman Date: Fri, 12 Oct 2007 21:07:23 +0000 (-0700) Subject: PCI: merge almost all of pci_32.h and pci_64.h together X-Git-Tag: v2.6.24-rc1~1393^2 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f3e6f164c2389853432454c89b316a8ab7485e2f;p=linux-2.6 PCI: merge almost all of pci_32.h and pci_64.h together It was just duplicated code...
