Subject: [PATCH V2 15/23] x86, ia64, pci: Convert arches to use PCI_DOMAINS_GENERIC.
Date: Wed, 16 Dec 2015 16:16:25 +0100 [thread overview]
Message-ID: <1450278993-12664-16-git-send-email-tn@semihalf.com> (raw)
In-Reply-To: <1450278993-12664-1-git-send-email-tn@semihalf.com>
Since we have now generic way to retrieve domain number using _SEG method,
x86 and ia64 can take advantage of it and forget about another
platform specific data from pci_sysdata.
