pcmcia: give socket time to power down

2007-07-31T22:39:38+00:00

Give sockets up to 100ms of additional time to power down.  otherwise we
might generate false warnings with KERN_ERR priority (like in bug #8262).

PM: remove deprecated dpm_runtime_* routines

2007-07-18T22:49:49+00:00

This patch (as933) removes the deprecated dpm_runtime_suspend() and
dpm_runtime_resume() routines from the PM core.  The only user of
those routines is the PCMCIA ds driver; local replacements are added.

powerpc: 8xx: fix whitespace and indentation

2007-07-17T17:23:02+00:00

Rolling forward PCMCIA driver, it was discovered that the indentation in
existing one, as well as in BSP side are very odd.  This patch is just result
of Lindent run ontop of culprit files.

Freezer: make kernel threads nonfreezable by default

2007-07-17T17:23:02+00:00

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes

2007-07-11T23:09:09+00:00

Well, first of all, I don't want to change so many files either.

What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.

In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(

Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)

Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.

Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

sysfs: kill unnecessary attribute->owner

2007-07-11T23:09:06+00:00

sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

For more info regarding lifetime rule cleanup, please read the
following message.

[POWERPC] 8xx: mpc885ads pcmcia support

2007-07-10T05:33:51+00:00

Adds support for PowerQuicc on-chip PCMCIA.  The driver is implemented as
of_device, so only arch/powerpc stuff is capable to use it, which now implies
only mpc885ads reference board.

To cope with the code that should be hooked inside driver, but is really board
specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds
necessary function pointers that are filled in the BSP code.

at91: fix enable/disable_irq_wake symmetry in pcmcia driver

2007-05-31T14:58:13+00:00

Fix enable_irq_wake and disable_irq_wake symmetry in at91 pcmcia driver

disable_irq_wake call must be symmetric with enable_irq_wake.  This patch
fix that problem for the at91_pcmia driver.  It seems that this patch was
forgotten when we've fixed irq_wake symmetry in all at91 related drivers.
It was discussed in the "at91 drivers and [enable/disable]_irq_wake
(wrong?) usage" thread on the linux-arm-kernel mailing list.
