From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yinghai Lu Subject: [PATCH 15/21] ia64/PCI: register busn_res for root buses Date: Mon, 7 May 2012 13:30:00 -0700 Message-ID: <1336422606-4244-16-git-send-email-yinghai@kernel.org> References: <1336422606-4244-1-git-send-email-yinghai@kernel.org> Return-path: In-Reply-To: <1336422606-4244-1-git-send-email-yinghai@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Bjorn Helgaas , Benjamin Herrenschmidt , Tony Luck , David Miller , x86 Cc: Dominik Brodowski , Andrew Morton , Linus Torvalds , Greg Kroah-Hartman , linux-pci@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, Yinghai Lu , Fenghua Yu , linux-ia64@vger.kernel.org List-Id: linux-arch.vger.kernel.org Add the host bridge bus number aperture from _CRS to the resource list. Like the MMIO and I/O port apertures, this is used when assigning resources to hot-added devices or in the case of conflicts.
