#     
#     Pull Kconfig file consolidation from Masahiro Yamada:
#      "Consolidation of bus (PCI, PCMCIA, EISA, RapidIO) config entries by
#       Christoph Hellwig.
#     
#       Currently, every architecture that wants to provide common peripheral
#       busses needs to add some boilerplate code and include the right
#       Kconfig files. This series instead just selects the presence (when
#       needed) and then handles everything in the bus-specific Kconfig file
#       under drivers/"
#     
#     * tag 'kconfig-v4.21-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
#       pcmcia: remove per-arch PCMCIA config entry
#       eisa: consolidate EISA Kconfig entry in drivers/eisa
#       rapidio: consolidate RAPIDIO config entry in drivers/rapidio
#       pcmcia: allow PCMCIA support independent of the architecture
#       PCI: consolidate the PCI_SYSCALL symbol
#       PCI: consolidate the PCI_DOMAINS and PCI_DOMAINS_GENERIC config options
#       PCI: consolidate PCI config entry in drivers/pci
#       MIPS: remove the HT_PCI config option
