Puts the content of arch/Kconfig in the "General setup" menu.

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.

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.

swsusp_pg_dir[] is used for suspend, but not for hibernation.
clean-up the ifdefs which worked by accident, while implying the opposite.
Delete the __nosavedata, which also implied the opposite.
Some day we may optimize CONFIG_ACPI_SLEEP to build minimal kernels
for just hibernate or just suspend but not both,
but today isn't that day.

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().

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).

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.

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?

setup_node_bootmem() makes NODE_DATA cacheline aligned,
and bootmap is page-aligned.
the patch updates find_e820_area() to make sure we can meet
the alignment constraints.

Change latencytop Kconfig entry so it doesn't list the archictectures
that support it. Instead introduce HAVE_LATENCY_SUPPORT which any
architecture can set. Should reduce patch conflicts.

This patch moves the micro-assembler in a separate implementation, as
it is useful for further run-time optimizations. The only change in
behaviour is cutting down printk noise at kernel startup time.
Checkpatch complains about macro parameters which aren't protected by
parentheses. I believe this is a flaw in checkpatch, the paste operator
used in those macros won't work with parenthesised parameters.

Commit 312b1485fb509c9bc32eda28ad29537896658cb8 made __INIT_REFOK expand
into .section .section ".ref.text", "ax". Since the assembler doesn't
tolerate stuttering in the source that broke all MIPS builds.
Since with this change Sam downgraded __INIT_REFOK the best fix is to
get replace it by the modern days operator. With MIPS the only user
of __INIT_REFOK and __INITDATA_REFOK (which was equally broken) being
unused anyway these can be deleted but that's subject of a separate
commit.
