Acked-by: Bjorn Helgaas <bhelg...@google.com> Again, please update the subject line to "PCI: Remove ..." I doubt that you'll get explicit acks from all the arches you touched, but I think it's reasonable to put at least patches 2 & 3 in -next soon after v3.11-rc1, so we should have time to shake out issues. > --- > arch/arm/Kconfig | 1 - > arch/ia64/Kconfig | 1 - > arch/mips/Kconfig | 2 -- > arch/powerpc/Kconfig | 1 - > arch/s390/Kconfig | 1 - > arch/sparc/Kconfig | 1 - > arch/tile/Kconfig | 1 - > arch/x86/Kconfig | 1 - > drivers/pci/Kconfig | 4 ---- > 9 files changed, 13 deletions(-) > > diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig > index 8ab5962..3413679 100644 > --- a/arch/arm/Kconfig > +++ b/arch/arm/Kconfig > @@ -435,7 +435,6 @@ config ARCH_NETX > config ARCH_IOP13XX > bool "IOP13xx-based" > depends on MMU > - select ARCH_SUPPORTS_MSI > select CPU_XSC3 > select NEED_MACH_MEMORY_H > select NEED_RET_TO_USER > diff --git a/arch/ia64/Kconfig b/arch/ia64/Kconfig > index 1a2b774..943d425 100644 > --- a/arch/ia64/Kconfig > +++ b/arch/ia64/Kconfig > @@ -9,7 +9,6 @@ config IA64 > select PCI if (!IA64_HP_SIM) > select ACPI if (!IA64_HP_SIM) > select PM if (!IA64_HP_SIM) > - select ARCH_SUPPORTS_MSI > select HAVE_UNSTABLE_SCHED_CLOCK > select HAVE_IDE > select HAVE_OPROFILE > diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig > index 7a58ab9..96c1225 100644 > --- a/arch/mips/Kconfig > +++ b/arch/mips/Kconfig > @@ -763,7 +763,6 @@ config CAVIUM_OCTEON_REFERENCE_BOARD > select SYS_HAS_CPU_CAVIUM_OCTEON > select SWAP_IO_SPACE > select HW_HAS_PCI > - select ARCH_SUPPORTS_MSI > select ZONE_DMA32 > select USB_ARCH_HAS_OHCI > select USB_ARCH_HAS_EHCI > @@ -799,7 +798,6 @@ config NLM_XLR_BOARD > select CEVT_R4K > select CSRC_R4K > select IRQ_CPU > - select ARCH_SUPPORTS_MSI > select ZONE_DMA32 if 64BIT > select SYNC_R4K > select SYS_HAS_EARLY_PRINTK > diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig > index c33e3ad..f9d9d8e 100644 > --- a/arch/powerpc/Kconfig > +++ b/arch/powerpc/Kconfig > @@ -734,7 +734,6 @@ config PCI > default y if !40x && !CPM2 && !8xx && !PPC_83xx \ > && !PPC_85xx && !PPC_86xx && !GAMECUBE_COMMON > default PCI_QSPAN if !4xx && !CPM2 && 8xx > - select ARCH_SUPPORTS_MSI > select GENERIC_PCI_IOMAP > help > Find out whether your system includes a PCI bus.
