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.

The interface should now be more sane and protect against races better. 

kobject_register() was split into two helpers: kobject_init() and kobject_add().
It calls both consecutively, though both are also exposed for use by users
that want to use the objects w/o adding them to the object hierarchy. 

kobject_unregister() was made simply a wrapper for kobject_del() and 
kobject_put(), which are both also exposed. The guts of kobject_put() was
moved into kobject_cleanup(), which it calls when the reference count hits
0. (This was done for clarity).

The infrastructure now takes a lot in kobject_get() and kobject_put() when
checking and modifying the objects' reference counts. This was an obvious
one that hsould have been fixed long ago. 

kobject_add() increments the refcount of the object, which is decremented
when kobject_del() is called. This guarantees that the object's memory
cannot be freed if it has been added to the hierarchy, and kobject_del() 
has not been called on it. 

kobject_init() is now the function that increments the refcount on the 
object's subsystem, which is decremented only after its release() method
has been called for the object in kobject_cleanup(). 

The documentation has been updated to reflect these changes. 

These security_ops are declared like

        int (*inode_mknod) (struct inode *dir, struct dentry *dentry,
                            int mode, dev_t dev);

with a mode and a dev_t argument.

But the users mistakenly had major, minor instead of mode, dev.

Given Andi Kleen's patch that introduces of VFS-level support for
nanosecond time resolutions, we should finally be able to export the
existing NFS client level support to userland.

In order to do so, the following patch will convert all NFS private 'raw
u64' values into the kernel-supported struct timespec directly in the
xdr_encode/xdr_decode routines.

It adds support for the nanosecond field in NFS 'setattr' calls, and in
nfs_refresh_inode().

Finally, there are a few cleanups in the nfs_refresh_inode code that
convert multiple use of the NFS_*(inode) macros into a single
dereference of NFS_I(inode).

was enabled, so split it up into "extable.c"

I thought this had been fixed some time ago, but must have never been 
picked up..

Convert it to #undef DEBUG.

devclass_{add,remove}_driver() had been implemented, but had never been
called.

This way, we make sure the driver gets added to the class's list
and is exported correctly in sysfs.

Since I believe kallsyms is important, this reimplements it sanely,
using the current module infrastructure, and not using an external
kallsyms script.

FYI, the previous interface was:

int kallsyms_symbol_to_address(
	const char       *name,			/* Name to lookup */
	unsigned long    *token,		/* Which module to start with */
	const char      **mod_name,		/* Set to module name or "kernel" */
	unsigned long    *mod_start,		/* Set to start address of module */
	unsigned long    *mod_end,		/* Set to end address of module */
	const char      **sec_name,		/* Set to section name */
	unsigned long    *sec_start,		/* Set to start address of section */
	unsigned long    *sec_end,		/* Set to end address of section */
	const char      **sym_name,		/* Set to full symbol name */
	unsigned long    *sym_start,		/* Set to start address of symbol */
	unsigned long    *sym_end		/* Set to end address of symbol */
	);

The new one is:
/* Lookup an address.  modname is set to NULL if it's in the kernel. */
const char *kallsyms_lookup(unsigned long addr,
			    unsigned long *symbolsize,
			    unsigned long *offset,
			    char **modname);

...since macro using it was changed from #if to #ifdef..
