commit 099a95f3591ade29da52131895a3ba9f92a0e82c upstream. Previously, dw_pcie_ep_set_msi() wrote all bits in the Message Control register, thus overwriting the PCI_MSI_FLAGS_64BIT bit. By clearing the PCI_MSI_FLAGS_64BIT bit, we break MSI on systems where the RC has set a 64 bit MSI address. Fix dw_pcie_ep_set_msi() so that it only sets MMC bits.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
