This cleans up the suspend Kconfig and removes the need to declare centrally which architectures support suspend. All architectures that currently support suspend are modified accordingly.

Always setting it is not usually a problem, however, since the infrastructure is only available for use after suspend_set_ops(). arch/arm/Kconfig | 3 +++ arch/blackfin/Kconfig | 4 ++++ arch/frv/Kconfig | 5 +++++ arch/i386/Kconfig | 4 ++++ arch/mips/Kconfig | 4 ++++ arch/powerpc/Kconfig | 4 ++++ arch/sh/Kconfig | 4 ++++ arch/x86_64/Kconfig | 3 +++ kernel/power/Kconfig | 21 +++------------------ 9 files changed, 34 insertions(+), 18 deletions(-) --- everything.orig/arch/i386/Kconfig 2007-11-07 14:45:28.591544215 +0100 +++ everything/arch/i386/Kconfig 2007-11-07 14:45:28.631515461 +0100 @@ -1323,3 +1323,7 @@ config KTIME_SCALAR config ARCH_HIBERNATION_POSSIBLE def_bool y depends on !SMP || !X86_VOYAGER + +config ARCH_SUSPEND_POSSIBLE + def_bool y + depends on !X86_VOYAGER --- everything.orig/arch/x86_64/Kconfig 2007-11-07 14:45:28.591544215 +0100 +++ everything/arch/x86_64/Kconfig 2007-11-07 14:45:28.631515461 +0100 @@ -716,6 +716,9 @@ menu "Power management options" source kernel/power/Kconfig +config ARCH_SUSPEND_POSSIBLE + def_bool y + config ARCH_HIBERNATION_POSSIBLE def_bool y --- everything.orig/kernel/power/Kconfig 2007-11-07 14:45:28.591544215 +0100 +++ everything/kernel/power/Kconfig 2007-11-07 14:45:28.641531465 +0100 @@ -64,7 +64,7 @@ config PM_TRACE config PM_SLEEP_SMP bool depends on SMP - depends on SUSPEND_SMP_POSSIBLE || ARCH_HIBERNATION_POSSIBLE + depends on ARCH_SUSPEND_POSSIBLE || ARCH_HIBERNATION_POSSIBLE depends on PM_SLEEP select HOTPLUG_CPU default y @@ -74,29 +74,14 @@ config PM_SLEEP depends on SUSPEND || HIBERNATION default y -config SUSPEND_UP_POSSIBLE - bool - depends on (X86 && !X86_VOYAGER) || PPC || ARM || BLACKFIN || MIPS \ - || SUPERH || FRV - depends on !SMP - default y - -config SUSPEND_SMP_POSSIBLE - bool - depends on (X86 && !X86_VOYAGER) \ - || (PPC && (PPC_PSERIES || PPC_PMAC)) || ARM - depends on SMP - default y - config SUSPEND bool "Suspend to RAM and standby" - depends on PM - depends on SUSPEND_UP_POSSIBLE || SUSPEND_SMP_POSSIBLE + depends on PM && ARCH_SUSPEND_POSSIBLE default y ---help--- Allow the system to enter sleep states in which main memory is powered and thus its contents are preserved, such as the - suspend-to-RAM state (i.e. the ACPI S3 state). + suspend-to-RAM state (e.g. the ACPI S3 state). config HIBERNATION bool "Hibernation (aka 'suspend to disk')" --- everything.orig/arch/blackfin/Kconfig 2007-11-07 14:44:55.551521971 +0100 +++ everything/arch/blackfin/Kconfig 2007-11-07 14:45:28.641531465 +0100 @@ -993,6 +993,10 @@ endmenu menu "Power management options" source "kernel/power/Kconfig" +config ARCH_SUSPEND_POSSIBLE + def_bool y + depends on !SMP + choice prompt "Select PM Wakeup Event Source" default PM_WAKEUP_GPIO_BY_SIC_IWR --- everything.orig/arch/arm/Kconfig 2007-11-07 14:44:55.651522948 +0100 +++ everything/arch/arm/Kconfig 2007-11-07 14:45:28.641531465 +0100 @@ -977,6 +977,9 @@ menu "Power management options" source "kernel/power/Kconfig" +config ARCH_SUSPEND_POSSIBLE + def_bool y + endmenu source "net/Kconfig" --- everything.orig/arch/mips/Kconfig 2007-11-07 14:44:55.701522460 +0100 +++ everything/arch/mips/Kconfig 2007-11-07 14:45:28.641531465 +0100 @@ -1999,6 +1999,10 @@ endmenu menu "Power management options" +config ARCH_SUSPEND_POSSIBLE + def_bool y + depends on !SMP + source "kernel/power/Kconfig" endmenu --- everything.orig/arch/sh/Kconfig 2007-11-07 14:44:55.801520344 +0100 +++ everything/arch/sh/Kconfig 2007-11-07 14:45:28.651528536 +0100 @@ -748,6 +748,10 @@ endmenu menu "Power management options (EXPERIMENTAL)" depends on EXPERIMENTAL && SYS_SUPPORTS_PM +config ARCH_SUSPEND_POSSIBLE + def_bool y + depends on !SMP + source kernel/power/Kconfig endmenu --- everything.orig/arch/frv/Kconfig 2007-11-07 14:44:55.861520941 +0100 +++ everything/arch/frv/Kconfig 2007-11-07 14:45:28.651528536 +0100 @@ -357,6 +357,11 @@ source "drivers/pcmcia/Kconfig" # should probably wait a while. menu "Power management options" + +config ARCH_SUSPEND_POSSIBLE + def_bool y + depends on !SMP + source kernel/power/Kconfig endmenu --- everything.orig/arch/powerpc/Kconfig 2007-11-07 14:45:28.591544215 +0100 +++ everything/arch/powerpc/Kconfig 2007-11-07 14:45:28.651528536 +0100 @@ -155,6 +155,10 @@ config ARCH_HIBERNATION_POSSIBLE depends on (PPC64 && HIBERNATE_64) || (PPC32 && HIBERNATE_32) default y +config ARCH_SUSPEND_POSSIBLE + def_bool y + depends on ADB_PMU || PPC_EFIKA || PPC_LITE5200 + config PPC_DCR_NATIVE bool default n --
