From: Jan Kiszka <jan.kiszka at siemens.com> Since e279b6c1d329 ("x86: start unification of arch/x86/Kconfig.*"), we have two PCI_MMCONFIG entries, one from the original i386 and another from x86_64. This consolidates both entries into a single one. The logic for x86_32, where this option was not under user control, remains identical. On x86_64, PCI_MMCONFIG becomes additionally configurable for SFI systems even if ACPI was disabled....
