[PATCH v2 0/5] Retrieve MSI/MSIX cap struct for once on setup

[Gavin Shan <shangw@linux.vnet.ibm.com>]

While we setup MSI or MSI-X for specific PCI device, the address of
MSI or MSI-X capability structure is figured out from the config
space for multiple times. That's unnecessary and the patchset addresses
that. With the patchset applied, the latency for MSI or MSI-X setup
would be decreased hopefully.

v1 -> v2:
	* Cache the MSI/MSI-X capability offset to pci_dev directly according
	  to Bjorn's suggestion.
	* Rebase to 3.9.RC5
