Date: Fri, 15 Apr 2016 19:06:38 +0200 Message-Id: <1460740008-19489-4-git-send-email-tn@semihalf.com> X-Mailer: git-send-email 1.9.1 In-Reply-To: <1460740008-19489-1-git-send-email-tn@semihalf.com> References: <1460740008-19489-1-git-send-email-tn@semihalf.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2726 Lines: 92 x86 and ia64 are the only arches that implement pcibios_{add|remove}_bus hooks and implement them in the same way. Moreover ARM64 is going to do the same. So it seems that acpi_pci_{add|remove}_bus is generic enough to be default option for pcibios_{add|remove}_bus hooks. Also, it is always safe to run acpi_pci_{add|remove}_bus as they have empty stubs for !ACPI case and return if ACPI has been switched off in run time. After all we can remove x86 and ia64 pcibios_{add|remove}_bus implementation.
