From 32a2eea795643929a43cbbba00d8c4a176b309bf Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 11 Oct 2007 16:57:27 -0400 Subject: PCI: Add 'nodomains' boot option, and pci_domains_supported global * Introduce pci_domains_supported global, hardcoded to zero if !CONFIG_PCI_DOMAINS. * Introduce 'nodomains' boot option, which clears pci_domains_supported on platforms that enable it by default (x86, x86-64, and others when they are converted to use this).
