Extentions to RapidIO switch support:
1. modify switch route operation declarations to allow using single
switch-specific file for family of switches that share the same route
table operations.2. add standard route table operations for switches that that support
route table manipulation registers as defined in the Rev.1.3 of RapidIO
specification.3. add clear-route-table operation for switches
4. add CPSxx and TSIxxx families of RapidIO switches

The original RapidIO driver suppose there is only one mpc85xx RIO controller
in system. So, some data structures are defined as mpc85xx_rio global, such
as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's
private members. And you can define multi RIO OF-nodes in dts file for multi
RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in
Freescale's silicon. And the mport operation function declaration should be
changed to know which RapidIO controller is target.Signed-off-by: Zhang Wei

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

This patch contains two fixes for RapisIO enumeration logic:
1. Fix enumeration in configurations with multiple switches. The patch adds:
a. Enumeration of an empty switch. Empty switch is a switch that
does not have any endpoint devices attached to it (except host device
or previous switch in a chain). New code assigns a phony destination
ID associated with the switch and sets up corresponding routes.b. Adds a second pass to the enumeration to setup routes to
devices discovered after switch was scanned.2. Fix enumeration failure when riohdid parameter has non-zero value.
Current version fails to setup response path to the host when it has
destination ID other that 0.Signed-off-by: Alexandre Bounine

- lockdep needs control of lock initialization, which the open-coded

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
