Add new sysfs attributes.
1. Routing information required to to reach the RIO device:
destid - device destination ID (real for for endpoint, route for switch)
hopcount - hopcount for maintenance requests (switches only)2. device linking information:
lprev - name of device that precedes the given device in the enumeration
or discovery order (displayed along with of the port to which it
is attached).
lnext - names of devices (with corresponding port numbers) that are
attached to the given device as next in the enumeration or
discovery order (switches only)Signed-off-by: Alexandre Bounine

Convert RIO switches device structures (rio_dev + rio_switch) into a
single allocation unit.This change is based on the fact that RIO switches are using common RIO
device objects anyway. Allocating RIO switch objects as RIO devices with
added space for switch information simplifies handling of RIO switch
devices.Signed-off-by: Alexandre Bounine

1. Change to create attribute "routes" only for switches.
2. Add a switch-specific callback to create/remove proprietary attributes.

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.Signed-off-by: Zhang Rui

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.http://article.gmane.org/gmane.linux.kernel/510293

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).Signed-off-by: Tim Schmielau

Include fixes for 2.6.14-git11. Should allow to remove sched.h from
module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390. Probably more
to come since I haven't yet checked the other archs.Signed-off-by: Tim Schmielau

Adds a RapidIO subsystem to the kernel. RIO is a switched fabric interconnect
used in higher-end embedded applications. The curious can look at the specs
over at http://www.rapidio.orgThe core code implements enumeration/discovery, management of
devices/resources, and interfaces for RIO drivers.There's a lot more to do to take advantages of all the hardware features.
However, this should provide a good base for folks with RIO hardware to start
contributing.Signed-off-by: Matt Porter
