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.

This patch adds sysfs class support to the Cosa driver. I have verified it
compiles but do not have the hardware to test it. If someone could that
would be helpful.

Thanks to Andrew Morton for pointing this out to me.

This patch adds basic kobject support to struct module, and it creates a 
/sys/module directory which contains all of the individual modules.  Each
module currently exports the refcount (if they are unloadable) and any
module paramaters that are marked exportable in sysfs.

Was written by me and Rusty over and over many times during the past 6 months.

.. here goes Take 2:

This adds /sys/class/adb/, removes unused devfs lines and updates a
comment to match reality.

Want a patch?

This patch adds class support to the Texas Instruments graphing calculators
with a parallel link cable.

I have verified it compiles. If someone has the hardware please verify it works.

This patch adds class support to pt.c which "the high-level driver for parallel
port ATAPI tape drives based on chips supported by the paride module." Which I
dont have in order to test.

I have verified it compiles but can not test it. If someone who has the
hardware could I would appreciate it.

This patch adds class support to pg.c, the parallel port generic ATAPI device driver.

I have verified it compiles but do not have the hardware. If someone does and
could test that would be helpful.

Thanks to Dru <andru@treshna.com>, who provided an easy way to reproduce
the problem.

What we have in lib/rwsem.c:__rwsem_do_wake():
	int woken, loop;
	^^^
and several lines below:
	loop = woken;
	woken *= RWSEM_ACTIVE_BIAS-RWSEM_WAITING_BIAS;
	woken -= RWSEM_ACTIVE_BIAS;

However, rw_semaphore->count is 64-bit on Alpha, so
RWSEM_WAITING_BIAS has been defined as -0x0000000100000000L.
Obviously, this blows up in the write contention case.

Fix new ISDN CAPI's internal ncci list semaphore if
CONFIG_ISDN_CAPI_MIDDLEWARE is disabled.

Thanks to Florian Schirmer.

This patch updates support for the Motorola PrPMC750 platform.  Most of the
size in this patch comes from merging prpmc750_pci.c and prpmc750_setup.c into
just prpmc750.c.

This patch adds openpic_hookup_cascade(offset, name, handler) which allows for
an arbitrary interrupt controller to be hooked up as a cascade to the openpic.
 This also allows for platforms to just not have a cascaded controller.

On pSeries LPARs we might end up with NUMA nodes that only have memory and
no CPUs.  Only the CPU configuration code actually set a node online, so
memory-only nodes wouldn't show up in sysfs.  Below patch adds the
set_online call to the memory loop too.
