2008-02-03Create arch/KconfigMathieu Desnoyers
Puts the content of arch/Kconfig in the "General setup" menu. Linus: > Should it come with a re-duplication of it's content into each > architecture, which was the case previously ? The oprofile and kprobes > menu entries were litteraly cut and pasted from one architecture to > another. Should we put its content in init/Kconfig then ? I don't think it's a good idea to go back to making it per-architecture, although that extensive "depends on <list-of-archiectures-here>" might indicate that there certainly is room for cleanup there. And I don't think it's wrong keeping it in kernel/Kconfig.xyz per se, I just think it's wrong to (a) lump the code together when it really doesn't necessarily need to and (b) show it to users as some kind of choice that is tied together (whether it then has common code or not). On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Sam Ravnborg: Stuff it into a new file: arch/Kconfig We can then extend this file to include all the 'trailing' Kconfig things that are anyway equal for all ARCHs. But it should be kept clean - so if we introduce such a file then we should use ARCH_HAS_whatever in the arch specific Kconfig files to enable stuff that is not shared. [...] The above suggestion is actually not exactly the best way to do it... First the naming.. A quick grep shows following usage today (in Kconfig files) ARCH_HAS 51 ARCH_SUPPORTS 4 HAVE_ARCH 7 ARCH_HAS is the clear winner. In the common Kconfig file do: config FOO depends on ARCH_HAS_FOO bool "bla bla" config ARCH_HAS_FOO def_bool n In the arch specific Kconfig file in a suitable place do: config SUITABLE_OPTION select ARCH_HAS_FOO The naming of ARCH_HAS_ is fixed and shall be: ARCH_HAS_<config option it will enable> Only a single line added pr. architecture. And we will end up with a (maybe even commented) list of trivial selects. - Yet another update : Moving to HAVE_* now.

2008-02-03Fix ARM to play nicely with generic Instrumentation menuMathieu Desnoyers
The conflicting commit for move-kconfiginstrumentation-to-arch-kconfig-and-init-kconfig.patch is the ARM fix from Linus : commit 38ad9aebe70dc72df08851bbd1620d89329129ba He just seemed to agree that my approach (just putting the missing ARM config options in arch/arm/Kconfig) works too. The main advantage it has is that it is smaller, does not need a cleanup in the future and does not break the following patches unnecessarily. It's just been discussed here http://lkml.org/lkml/2008/1/15/267 However, Linus might prefer to stay with his own patch and I would totally understand it that late in the release cycle. Therefore I submit this for the next release cycle.

2008-02-01Suspend: Introduce begin() and end() callbacksRafael J. Wysocki
On ACPI systems the target state set by acpi_pm_set_target() is reset by acpi_pm_finish(), but that need not be called if the suspend fails.  All platforms that use the .set_target() global suspend callback are affected by analogous issues. For this reason, we need an additional global suspend callback that will reset the target state regardless of whether or not the suspend is successful.  Also, it is reasonable to rename the .set_target() callback, since it will be used for a different purpose on ACPI systems (due to ACPI 1.0x code ordering requirements). Introduce the global suspend callback .end() to be executed at the end of the suspend sequence and rename the .set_target() global suspend callback to .begin(). Signed-off-by: Rafael J.

2008-02-01x86: avoid section mismatch involving arch_register_cpuAlexander van Heukelum
Avoid section mismatch involving arch_register_cpu. Marking arch_register_cpu as __init and removing the export for non-hotplug-cpu configurations makes the following warning go away: Section mismatch in reference from the function arch_register_cpu() to the function .devinit.text:register_cpu() The function arch_register_cpu() references the function __devinit register_cpu(). This is often because arch_register_cpu lacks a __devinit annotation or the annotation of register_cpu is wrong. The only external user of arch_register_cpu in the tree is in drivers/acpi/processor_core.c where it is guarded by ACPI_HOTPLUG_CPU (which depends on HOTPLUG_CPU).

The ebx variables can easily be unsigned, may as well. arch/x86/kernel/cpu/common.c:261:21: warning: incorrect type in argument 2 (different signedness) arch/x86/kernel/cpu/common.c:261:21: expected unsigned int *eax arch/x86/kernel/cpu/common.c:261:21: got int *<noident> arch/x86/kernel/cpu/common.c:262:9: warning: incorrect type in argument 3 (different signedness) arch/x86/kernel/cpu/common.c:262:9: expected unsigned int *ebx arch/x86/kernel/cpu/common.c:262:9: got int *<noident> arch/x86/kernel/cpu/common.c:263:9: warning: incorrect type in argument 4 (different signedness) arch/x86/kernel/cpu/common.c:263:9: expected unsigned int *ecx arch/x86/kernel/cpu/common.c:263:9: got int *<noident> arch/x86/kernel/cpu/common.c:264:9: warning: incorrect type in argument 5 (different signedness) arch/x86/kernel/cpu/common.c:264:9: expected unsigned int *edx arch/x86/kernel/cpu/common.c:264:9: got int *<noident> arch/x86/kernel/cpu/common.c:293:30: warning: incorrect type in argument 3 (different signedness) arch/x86/kernel/cpu/common.c:293:30: expected unsigned int *ebx arch/x86/kernel/cpu/common.c:293:30: got int *<noident> arch/x86/kernel/cpu/common.c:350:22: warning: incorrect type in argument 2 (different signedness) arch/x86/kernel/cpu/common.c:350:22: expected unsigned int *eax arch/x86/kernel/cpu/common.c:350:22: got int *<noident> arch/x86/kernel/cpu/common.c:351:10: warning: incorrect type in argument 3 (different signedness) arch/x86/kernel/cpu/common.c:351:10: expected unsigned int *ebx arch/x86/kernel/cpu/common.c:351:10: got int *<noident> arch/x86/kernel/cpu/common.c:352:10: warning: incorrect type in argument 4 (different signedness) arch/x86/kernel/cpu/common.c:352:10: expected unsigned int *ecx arch/x86/kernel/cpu/common.c:352:10: got int *<noident> arch/x86/kernel/cpu/common.c:353:10: warning: incorrect type in argument 5 (different signedness) arch/x86/kernel/cpu/common.c:353:10: expected unsigned int *edx arch/x86/kernel/cpu/common.c:353:10: got int *<noident> arch/x86/kernel/cpu/common.c:362:30: warning: incorrect type in argument 3 (different signedness) arch/x86/kernel/cpu/common.c:362:30: expected unsigned int *ebx arch/x86/kernel/cpu/common.c:362:30: got int *<noident> Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-02-01x86: fix section mismatch warning in kernel/pci-calgarySam Ravnborg
Fix following warning: WARNING: arch/x86/kernel/built-in.o(.text+0x1eb41): Section mismatch in reference from the function calgary_handle_quirks() to the function .init.text:calgary_set_split_completion_timeout() calgary_handle_quirks() are only called at __init time (in calgary_init_one() via handle_quirks ops).

Fix following warning: WARNING: o-x86_64/arch/x86/kernel/built-in.o(.text+0x13d15): Section mismatch in reference from the function acpi_map_lsapic() to the function .cpuinit.text:mp_register_lapic() The function acpi_map_lsapic() is exported and thus not annotated. But the sole user is acpi/processor_core.c in a __cpuinit path. So create a small wrapper and put back the annotation thus avoiding the warning.

2008-02-01x86: fix section mismatch warnings when referencing notifiersSam Ravnborg
Fix the following warnings: WARNING: arch/x86/kernel/built-in.o(.exit.text+0xf8): Section mismatch in reference from the function msr_exit() to the variable .cpuinit.data:msr_class_cpu_notifier WARNING: arch/x86/kernel/built-in.o(.exit.text+0x158): Section mismatch in reference from the function cpuid_exit() to the variable .cpuinit.data:cpuid_class_cpu_notifier WARNING: arch/x86/kernel/built-in.o(.exit.text+0x171): Section mismatch in reference from the function microcode_exit() to the variable .cpuinit.data:mc_cpu_notifier In all three cases there were a function annotated __exit that referenced a variable annotated __cpuinitdata. The fix was to replace the annotation of the notifier with __refdata to tell modpost that the reference to a _cpuinit function in the notifier are OK. The unregister call that references the notifier variable will simple delete the function pointer so there is no problem ignoring the reference. Note: This looks like another case where __cpuinit has been used as replacement for proper use of CONFIG_HOTPLUG_CPU to decide what code are used for HOTPLUG_CPU.

2008-02-01x86: silence section mismatch warning in smpboot_64.cSam Ravnborg
Silence the following warning: WARNING: o-x86_64/arch/x86/kernel/built-in.o(.text+0x17cd3): Section mismatch in reference from the function remove_cpu_from_maps() to the variable .cpuinit.data:cpu_initialized remove_cpu:maps() had a single user: __cpu_disable() so mark it static and annotate it with __ref to silence the warning from modpost. _cpu_disable() has a single user in kernel/cpu.c: => take_cpu_down() which again has a single user in the following call: => __stop_machine_run(take_cpu_down, &tcd_param, cpu); Here a kthread is created. So maybe the warning is correct and the right fix is to remove the __cpuinitdata annotation of cpu_initialized? Note: The analysis were disturbed by the fact that we had a variable with the same name in cpu/common.c - but this is 32 bit only] Note: Should smpboot_64 use cpu_clear()?
