12 years agoCreate arch/Kconfig
Mathieu Desnoyers [Sat, 2 Feb 2008 20:10:33 +0000]
Create arch/Kconfig

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

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.

12 years agoFix ARM to play nicely with generic Instrumentation menu
Mathieu Desnoyers [Sat, 2 Feb 2008 20:10:32 +0000]
Fix ARM to play nicely with generic Instrumentation menu

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.

12 years agokconfig: ignore select of unknown symbol
Sam Ravnborg [Sat, 2 Feb 2008 20:09:57 +0000]
kconfig: ignore select of unknown symbol

We have had warnings for a long time about select of unknow symbol
but the warnings does not really makes sense since we may
select a symbol that is relevant and defined in one
arch but not in another arch.
And as long as we do not use a common set of Kconfig files
for all archs lets just ignore this case.

Previously we have used this to find bad uses of
select but we need a more relaible method to do so.

Since with this change Sam downgraded __INIT_REFOK to just a backward
compat thing and there being only a single use in the MIPS arch code the
best solution is to delete both of __INIT_REFOK and __INITDATA_REFOK (which

12 years agofix writev regression: pan hanging unkillable and un-straceable
Nick Piggin [Sat, 2 Feb 2008 14:01:17 +0000]
fix writev regression: pan hanging unkillable and un-straceable

Frederik Himpe reported an unkillable and un-straceable pan process.

Zero length iovecs can go into an infinite loop in writev, because the
iovec iterator does not always advance over them.

The sequence required to trigger this is not trivial. I think it
requires that a zero-length iovec be followed by a non-zero-length iovec
which causes a pagefault in the atomic usercopy. This causes the writev
code to drop back into single-segment copy mode, which then tries to
copy the 0 bytes of the zero-length iovec; a zero length copy looks like
a failure though, so it loops.

Put a test into iov_iter_advance to catch zero-length iovecs. We could
just put the test in the fallback path, but I feel it is more robust to
skip over zero-length iovecs throughout the code (iovec iterator may be
used in filesystems too, so it should be robust).

12 years agoide-floppy: factor out ioctl handlers from idefloppy_ioctl()
Borislav Petkov [Sat, 2 Feb 2008 18:56:35 +0000]
ide-floppy: factor out ioctl handlers from idefloppy_ioctl()

By passing idefloppy_floppy_t *floppy to the factored out functions, we get
rid of (almost) all local vars so stack usage should be at minimum here. Also,
we merge idefloppy_begin_format() into idefloppy_format_start() since it is its
only user. Also, rename idefloppy_format_start() to idefloppy_format_unit().
Finally, rename the reworked functions to ide_floppy..().

ide-floppy: remove struct idefloppy_capabilities_page

This change is rather temporary and is in preparation of using generic commands
as is the case with ide-cd and the uniform cdrom layer (i.e. init_cdrom_command())
However, before this happens, we'll have to remove all typedefs and teach
idefloppy_create_mode_sense_cmd() to work directly on u8 buffers.

Also, since idefloppy_get_capability_page() was used to read only the sfrp bit,
rename the latter so that the name reflects what it does.

12 years agoide-floppy: disambiguate function names
Borislav Petkov [Sat, 2 Feb 2008 18:56:33 +0000]
ide-floppy: disambiguate function names

There were two almost identical function names in ide-floppy.c, which makes
their distinction almost impossible. While ide_floppy_release() cleans up the
object after the last reference to it has been dropped, idefloppy_release() is
the blkdev .release method from struct block_device_operations which releases
that last reference.

Rename ide_floppy_release() to idefloppy_cleanup_obj() in order to make its
purpose more clear.

There should be no functionality change resulting from this patch.
