From: Jiang Liu <liuj97@xxxxxxxxx> As suggested by Bjorn Helgaas and Don Dutile in threads http://www.spinics.net/lists/linux-pci/msg15663.html, we could improve access to PCIe capabilities register in to way: 1) cache content of PCIe Capabilities Register into struct pce_dev to avoid repeatedly reading this register because it's read only. 2) provide access functions for PCIe Capabilities registers to hide differences among PCIe base specifications, so the caller don't need to handle those differences. This patch set applies to git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git pci-next These patch set is still RFC. It provides the new interfaces and has made the major changes to adopt those new interfaces. But there are still several device drivers left untouched. Any comments about the new interfaces are welcomed, especially about function names:). Once we reach an agreement, I will send out a formal version with all needed work done.
