Patch to replace the soon to be defunct pci_find_device with the
new function pci_dev_present. I found 8 .c files (outside of /drivers/net)
that used pci_find_device without the dev it returned. therefore it
was replaceable with the new function.

As pci_find_device is going away it needs to be replaced. In this case the dev
returned from pci_find_device was not being used so pci_dev_present was the
appropriate replacement.

This has been compile and boot tested on a T22.

Here I have attached pci mmconfig fix for 2.6.9 kernel.

This will fix the flush error in pci_mmcfg_write.

When pci_mmcfg_write is used to program the PMCSR in the Power
Management Capability structure of PCI config space in the PCI Express
device to a different power state, the dummy readl to flush the previous
write violates the transition delay specified in the PCI power
management spec. Please see PCI Power Management Spec. 1.2 Table 5-6.
For example, while changing the power state of the device through PMCSR
register, a transition delay of 10msec is required before any access can
be made to the device.

Since the configuration write access for PCI Express is non posted,
flushing is not necessary and  it will be safe to remove the dummy
readl.

This patch will remove dummy readl function implemented in
"pci_mmcfg_write" and use set_fixmap_nocahe instead of set_fixmap.

Linus has requested that the sysfs rom attribute be changed to require
enabling before it works. echo "0" to the attribute to disable,
echoing anything else enables the rom output. The concern is that
something like a file browser could inadvertently read the attribute
and change the state of the hardware without the user's knowledge.

The attached patch includes the previous patch plus the enabling logic.

This is the ASPM patch against 2.6.10-rc1-mm2.

As mentioned in my last email, this patch has a slight difference than
the one for 2.6.10-rc1,  because the irqbalance quirk was moved from
drivers/pci/quirks.c in 2.6.10-rc1 to arch/i386/kernel/quirks.c in
2.6.10-rc1-mm2.

To make spinlock/rwlock initialization consistent all over the kernel,
this patch converts explicit lock-initializers into spin_lock_init() and
rwlock_init() calls.

Currently, spinlocks and rwlocks are initialized in two different ways:

  lock = SPIN_LOCK_UNLOCKED
  spin_lock_init(&lock)

  rwlock = RW_LOCK_UNLOCKED
  rwlock_init(&rwlock)

this patch converts all explicit lock initializations to
spin_lock_init() or rwlock_init(). (Besides consistency this also helps
automatic lock validators and debugging code.)

The conversion was done with a script, it was verified manually and it
was reviewed, compiled and tested as far as possible on x86, ARM, PPC.

There is no runtime overhead or actual code change resulting out of this
patch, because spin_lock_init() and rwlock_init() are macros and are
thus equivalent to the explicit initialization method.

That's the second batch of the unifying patches.

There is a similar problem reported by s390 people where we see parent
kobject (directory) going away before child kobject (sub-directory). It
seems kobject code is able to handle this, but not the sysfs. What could
be happening that in sysfs_remove_dir() of parent directory, we try to
remove its contents. It works well with the regular files as it is the
final removal for sysfs_dirent corresponding to the files. But in case
of sub-directory we are doing an extra sysfs_put().  Once while removing
parent and the other one being the one from when sysfs_remove_dir() is
called for the child.

The following patch worked for the s390 people, I hope same will work in
this case also.


o Do not remove sysfs_dirents corresponding to the sub-directory in
  sysfs_remove_dir(). They will be removed in the sysfs_remove_dir() call
  for the specific sub-directory.

This is a relatively small changeset, to address small nagging problems.
Andrew pointed me at the double registration specifically, so I had to do
something about it. At least now Fabio's box won't collapse if he configures
UB by mistake. Also, a few people complained that the help text was
misleading.

I have not done anything about the oops on disconnect which happens to
Martin Schlemmer. It's next. After that I can get to Peter Jones' CD
burning patch and doing resets.

- Fix double kobject registration and eventual oops on unplug if a device
  is not cooperating.
- Add a reference to usb-storage into the configuration help.
- Just upping timeouts fixes my ZIP drive.
- Max out the diag (trace) file size.
- Set capacity to zero in case the media is absent. It works in 2.4.10-rc1.

Looks like kobject_uevent_init is executed before netlink_proto_init and
consequently always fails.  Not cool.

Attached patch switches the initialization over from core_initcall (init
level 1) to postcore_initcall (init level 2).  Netlink's initialization
is done in core_initcall, so this should fix the problem.  We should be
fine waiting until postcore_initcall.

Add the sysfs path of the physical device to the hotplug event of class
and block devices. This should solve the userspace issue not to know if
the device is a virtual one and the "device" symlink will never be created,
but we sit there and wait for it to show up not knowing when we should
give up.

Also the bus name is added to the hotplug event, so we don't need to
reverse lookup in the /sys/bus/* directory which bus our physical
device belongs to. This is e.g. the value matched against the BUS= key,
that may be used in an udev rule.
