Peter Anvin" Cc: LKML , Jesse Barnes Subject: [PATCH] x86: fix section mismatch in pci_scan_bus Message-ID: <20080429203848.GA13741@uranus.ravnborg.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.2.1i Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Fix following section mismatch warning: WARNING: vmlinux.o(.text+0x275616): Section mismatch in reference from the function pci_scan_bus() to the function .devinit.text:pci_scan_bus_parented() The warning was seen with a CONFIG_DEBUG_SECTION_MISMATCH=y build. The inline function pci_scan_bus refer to functions annotated __devinit - so annotate it __devinit too. This revealed a few x86 specific functions that were only used from __init or __devinit context. So annotate these __devinit and the warning was killed. The added include in pci.h was not strictly required but added to avoid being dependent on indirect includes.
