Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
lib: use generic pci_iomap on all architectures Many architectures don't want to pull in iomap.c, so they ended up duplicating pci_iomap from that file. That function isn't trivial, and we are going to modify it https://lkml.org/lkml/2011/11/14/183 so the duplication hurts. This reduces the scope of the problem significantly, by moving pci_iomap to a separate file and referencing that from all architectures. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: alpha: drop pci_iomap/pci_iounmap from pci-noop.c mn10300: switch to GENERIC_PCI_IOMAP mn10300: add missing __iomap markers frv: switch to GENERIC_PCI_IOMAP tile: switch to GENERIC_PCI_IOMAP tile: don't panic on iomap sparc: switch to GENERIC_PCI_IOMAP sh: switch to GENERIC_PCI_IOMAP powerpc: switch to GENERIC_PCI_IOMAP parisc: switch to GENERIC_PCI_IOMAP mips: switch to GENERIC_PCI_IOMAP microblaze: switch to GENERIC_PCI_IOMAP arm: switch to GENERIC_PCI_IOMAP alpha: switch to GENERIC_PCI_IOMAP lib: add GENERIC_PCI_IOMAP lib: move GENERIC_IOMAP to lib/Kconfig Fix up trivial conflicts due to changes nearby in arch/{m68k,score}/Kconfig

Find out whether you have a PCI motherboard. PCI is the name of a
bus system, i.e. the way the CPU talks to the other stuff inside
