It seems atomic_inc_and_test() is missing on alpha.

It's easy to do when the arch provides atomic_inc_return().

Lots of architectures have atomic_add_return() and no atomic_add_negative().

We can implement the latter in terms of the former.

I'm about to change the meaning (and name) of page->count.  Go through and fix
up all those places which are open-coding references to it.

Forgot to include this with my original patch a few weeks ago...

OK.  I've attached a new version of the patch against linux-2.6.6.
I'll send a patch against current lm_sensors CVS removing the extra
exit command in a separate mail.

Errh, I just added it to document my sloppyness.  It was never meant
to be in the patch I sent you.  Sorry.  Removed in the attached patch.
The style of these drivers seem to be "just working, making no noise"
so I assume informational printk's are unwanted.

This patch adds DID support for ICH6 and 6300ESB to i2c-i801.c(SMBus).
In order to add this support I needed to patch pci_ids.h with the SMBus
DID's.  To keep things orginized I renumbered the ICH6 and ESB entries
in pci_ids.h.  I then patched the piix IDE and i810 audio drivers to
reflect the updated #define's.  I also removed an error from irq.c;
there was a reference to a 6300ESB DID that does not exist.

I needed this to get an APM + UHCI config to behave on resume.
Applies against your BK of last night ... OHCI and EHCI do
some of this manually, they could be simplified later.

o The following patch cleans up sysfs_rename_dir(). It now checks the
  return code of kobject_set_name() and propagates the error code to its
  callers. Because of this there are changes in the following two APIs. Both
  return int instead of void.

int sysfs_rename_dir(struct kobject * kobj, const char *new_name)
int kobject_rename(struct kobject * kobj, char *new_name)

[note, I changed this a bit to be nicer on the system log, greg k-h]

The short version is:  it's missing this patch.

It also could hide real bugs, and that's not good.  And the name
implies that a reference is grabbed, and that's not true at all.

If this is hiding real problems, we need to find them.

Pretty useless stuff.  If this was hiding anything real, we need to find out.

Following patch merges the support for Keyspan UPR-112 USB serial adapter
from 2.4 to 2.6.

Also fix up some of the other printk() calls to be dev_* calls.

hm, not sure what's happened there...

Of course!  I trust you won't mind me changing your suggested fix
slightly.  This should do an equally good job of repairing things, and it
will prevent other possible invalid references as well.

Hi Alan, thanks for doing this.  It looks and works OK.  I added some name
changes: all struct usb_interface pointers are now called intf; and, when
reasonable, variables holding interface numbers are now all called ifnum.
This drowns your original changes in a sea of churning names, I hope you
don't mind.

This patch should help correct the "missing diagnostics with
CONFIG_USB_DEBUG during CDC Ethernet probe()" issue.  Some
folk are having problems with firmware that doesn't respond
properly to descriptor fetches -- which is unnecessarily
confusing because the diagnostics aren't being printed.

The following patch fixes the race involved between unregistering a kobject
and simultaneously opeing a corresponding attribute file in sysfs.

Ideally sysfs should take a ref.  to the kobject as long as it has dentries
referring to the kobjects, but because of current limitations in
module/kobject ref counting, sysfs's pinning of kobject leads to
hang/delays in rmmod of certain modules.  The patch checks for unhashed
dentries in check_perm() while opening a sysfs file.  If the dentry is
still hashed then it goes ahead and takes the ref to kobject.  This done
under the per dentry lock.  It does this in the inline routine
sysfs_get_kobject(dentry).

1) kobject_set_name-cleanup-01.patch

This patch corrects the following by checking the reutrn code from
kobject_set_name().

bus_add_driver()
bus_register()
sys_dev_register()



o The following patch cleansup the kobject_set_name() users. Basically checking
  return code from kobject_set_name(). There can be error returns like -ENOMEM
  or -EFAULT from kobject_set_name() if the name length exceeds KOBJ_NAME_LEN.
