- Don't do extra dget() when creating symlink. 
This is a long-standing bug with a simple and obvious fix. We were doing 
an extra dget() on the dentry after d_instantiate(). It only gets decremented
once on removal, so the dentry was never really going away, and the directory
wasn't, either. 

- Use simple_unlink() instead of sysfs_unlink().

- Use simple_rmdir() instead of our own, unrolled, version. 

- Remove MODULE_LICENSE(), since it's always in the kernel.

- Use PCI_BUS_NUM_RESOURCES instead of hardcoded `4' in
  pci_find_parent_resource;
- clean up pci_claim_resource() and make it a bit more informative
  on errors;
- pdev_sort_resources() must be __devinit, as it's called from
  pbus_assign_resources_sorted(), which is __devinit now;
- fix one remaining dev->name in debugging printk.

The detection of subtractive decoding bridges is broken: `class' variable
doesn't contain ProgIf byte at this point, I should check `dev->class'
instead.

This fixes resource allocation problems on certain docking stations.

The dev_t argument of sys_mknod is passed to vfs_mknod, and is then cast
to int when foo_mknod is called, and is subsequently very often cast
back to dev_t.  (For example, minix_mknod() calls minix_set_inode() that
takes a dev_t.)

This is a cleanup that avoids this back-and-forth casting by giving
foo_mknod a prototype with dev_t.  In most cases now the dev_t is
transmitted untouched until init_special_inode.

It also makes the two routines hugetlbfs_get_inode() and
shmem_get_inode() static.

Fixes miscalculation of required module size due to alignment issues of
first section after common, and also doesn't think that no init section
is an allocation failure.

Patch from Adam Richter.  I have a nicer solution based on aliases, but
it requires coordination with USB, PCI and PCMCIA maintainers, which is
taking time.

This restores the old code in the meantime: one week without this is too
long for people who need it.

This removes Rules.make inclusions, makes make clean work properly,
removes EXTRA_TARGETS where not needed, and fixes a couple of compile
warnings in the boot wrappers where <linux/string.h> wasn't included.

This solves some mutual inclusion problems.

Now atomic.h defines the smp_mb__* macros completely itself without
needing the smp_mb definition from <asm/system.h>

parse_interface allocates the incorrect storage size for additional
altsettings (new buffer) leading to a BUG being triggered in
mm/slab.c:1453 when we do the memcpy from the old buffer to the new
buffer (writing beyond new buffer).
Patch appended, tested with an OV511 on an Intel PIIX4

Al pointed out that the current name of get_lease is extremely confusing
and I agree.

This (a) renames it to break_lease and (b) fixes a bug noticed by Dave
Hansen which could cause a NULL pointer dereference under high load.

This makes the driver model core (for devices) exploit the kobject
infrastructure more and make the resulting code quite a bit simpler. 

For one, device_register() mimmicks kobject_register() in that it now only
calls device_initialize() and device_add() back to back. Similarly, 
device_unregister() calls device_del() and put_device() consecutively. 

device_del() no longer removes and frees the device, it only removes them.
It also removes the devices from the global and sibling lists. This was 
previously done by device_put(), but moved here to be symmetrical with 
device_add().

The device's parent is now only incremented in device_add() and decremented
in device_del(), fixing a bug in which the parent's refcount was incremented
twice. 

Because of these simplifications, the core can easily be converted to use 
the kobject reference counting infrastructure. get_device() now simply 
forwards the call to kobject_get() and ditto for put_device(). 
device_release() is implemented to handle the freeing of devices once their
reference count reaches 0.

Since we're using the kobject refcounting model, we no longer need the 
checking or setting of the device state field, so it has been removed. 
The only users of it were the power routines. In those, it is implicit that
we have a valid device, since we've already taken device_sem, and we're 
walking the list (all modifications are protected by device_sem).

struct device::lock, and the helpers to lock/unlock have been removed. No
one has ever used them, and no one is likely to use them.

 - removed a few #ifdefs in the main code
 - cleaned up the failure logic in initialization.

This removes the code from cap_sysget that fills out the capability set
being returned to userspace.  The module handles this in a policy
specific way.  This updates the dummy.c module to fill in return data
according to superuser policy, and also disables setting capabilities in
superuser policy.

sysfs has always had a bug that would allow a read-only file to be opened 
for writing. It has also returned 0 on write when there was no store method
defined for the file. 

This addresses both via sysfs_open_file(). It checks the flags the file was
opened with and compares them with the mode of the inode. If the mode does
not support the flags passed, -EPERM is returned.

If the sysfs_ops for the object does not have the correct method for the 
flags, -EACCESS is returned. 

Since all checks happen on open(), the corresponding checks in the read()
and write() methods have been removed. 

sending routines don't set it up.

from "write()" is an error condition, and hang retrying.

Return EINVAL in sysfs instead.
