On arm, PCI_REASSIGN_ALL_RSRC is used only in pcibios_assign_all_busses(), which helps decide whether to reconfigure bridge bus numbers. It has nothing to do with BAR assignments. On arm64 and powerpc, pcibios_assign_all_busses() tests PCI_REASSIGN_ALL_BUS, which makes more sense. Align arm with arm64 and powerpc, so they all use PCI_REASSIGN_ALL_BUS for pcibios_assign_all_busses(). Remove PCI_REASSIGN_ALL_RSRC from the generic, Tegra, Versatile, and R-Car drivers. These drivers are used only on arm or arm64, where PCI_REASSIGN_ALL_RSRC is not used after this change, so removing it should have no effect. No functional change intended.

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.
