This patch uses the interrupt URB on the ax8817x for link detection.
This allows the driver to notify userspace when link drops/comes back
so it can take action such as run dhclient, etc.

I was also able to reduce the bind function by using some of the stock
mii_xxx calls as well as my own for handling initial link negotiation.

It makes sense for APIs involved in cleanup activities (like kfree()) to
accept NULL arguments.  Doing so frees drivers from the responsibility of
checking whether each resource was actually acquired before trying to
release it.  Accordingly, this patch makes usb_unlink_urb() and
usb_kill_urb() accept a NULL pointer (which used to be acceptable until I
changed it) and notes explicitly in the kerneldoc that such arguments are
permitted.

 This patch does a cleanup for usb/core/file.c::usb_major_init(), which
 is:

*) in error condition, returns the error code from register_chrdev(),
   insted returning -EBUSY;

*) adds missing audit for class_register();

*) only calls devfs_mk_dir() if the prior calls have success.

Ok here is a patch to make the mount options work.  In addition to
implementing the remount function, it removes the parse_options() call
from usb_fill_super and adds a "ignore" flag around the mounting that gets
done in create_special_files.  The parse_options call in usb_fill_super is
removed because it is not needed when remount is implemented.  The
ignore_mount flag is needed because the simple_pin_fs function calls
remount with no mount options - i.e. it's not a real mount.  So the mount
options would be cleared out.  The ignore_mount flag causes the remount
function to only act on real mounts.

[PATCH] USB: fix up the wording in the emi26 firmware file to match the other kernel firmware files.
Signed-off-by: Greg Kroah-Hartman <greg@kroah.com>

This patch fixes a logical hole in the hub driver.  It's possible for the
driver to be unbound from a hub without physically unplugging the hub.
For example, writing 0 into the bConfigurationValue attribute file will
have this effect.  When this happens, we need to make sure that all the
child devices of the hub are logically disconnected and their ports
disabled.

That's what this patch does.  It's a little bit tricky because we can't
simply call usb_disconnect() from within the hub driver's disconnect()
routine.  While that routine is running it holds the usb bus writelock,
but usb_disconnect() would try to acquire it again.  Instead
schedule_work() is used, so after a brief delay the children will be
removed.

This patch adds a pointer to the hub's usb_device into the usb_hub private
structure.  It's a small change, and permits a small amount of
simplification in a few spots, i.e., avoid calling interface_to_usbdev().
This doesn't really do much in itself, but it's a prerequisite for the
next patch.  (A situation arises where we can't use the interface pointer
to find the usb_device because the interface might not exist.)

Okay, here's a revised patch (as332b).  This tries first to ask for 255
bytes, and if that fails then it asks for the length and the full
descriptor.  Hopefully nobody will object to applying this version...

You know, it occurs to me that the have_langid field in usb_device could
easily be eliminated.  Just set string_langid to -1 during initialization
and test for whether or not it is >= 0.  I'll do that some other time.

This is a rerun of as278, updated to match the current source.  It changes

This patch is a slightly revised version of as277c, updated to match the
current source.  The only difference from the older version is that this
makes urb->use_count into an atomic_t, to avoid the overhead of an extra
locking step each time an URB is submitted and given back.  The important
features of this patch are:

	-EPERM added to Documentation/usb/error-codes.txt.

	Failure to use URB_ASYNC_UNLINK with usb_unlink_urb() is
	deprecated in the documentation.

	New ->reject and ->use_count fields added to struct urb.
	The reject field is protected by urb->lock, and locking is
	required only in usb_kill_urb() which doesn't have to be fast.

	Single wait_queue used for all processes waiting inside
	usb_kill_urb().  The wait queue is woken up only when an URB
	is given back with ->reject set.

	usb_rh_status_dequeue() changed to return int.  It looks like
	this function should be declared static; it's not used outside
	the hcd.c file.

	Prototype for unlink_urb() in struct usb_operations is changed
	to include a status code argument.  This is necessary so that
	the different unlink paths can return -ENOENT and -ECONNRESET
	as appropriate.

	Support for synchronous usb_unlink_urb() has been removed;
	such calls are passed to usb_kill_urb().

	Kerneldoc for usb_unlink_urb() is updated.

	usb_kill_urb() added to urb.c.

	hc_simple() host driver is partially updated -- it should
	compile but it won't really work right.

a recent change did a s/tcp_memory_pressure/tcp_prot.memory_pressure/.

'strace' shows a problem with a missing release_task for self-reaping
clones that have been traced.  We need to defer releasing them until the
tracer is done with them, but if the tracer dies, we need to handle that
case gracefully too. 

We do that by having 'forget_original_parent()' generate a list of tasks
to release when this case happens.

Patch based on discussions on linux-kernel, and suggestions from Roland
McGrath <roland@redhat.com>.

This fixes a corner-case NX bug: the x86 SMP kernel doesnt boot on SMP
Opterons if NX is enabled [and mem=nopentium is specified], due to
kernel-space NX protection preventing the SMP trampoline from being
executable. 

Since the SMP trampoline is a rare case of 'dynamic code' executed by
the kernel (it has to be below 640K so it cannot be part of the kernel
text itself), i've added the necessary infrastructure to enable/disable
executability of specific kernel pages. 

We cannot simply disable NX via the MSR because we've got the NX bits in
the kernel pagetables, which are set up before we do the SMP bootup. 
The NX bit in the pagetables is undefined if EFER.NXE is 0, so we cannot
count on NX-capable CPUs not faulting when they encounter them. 

I've tested the x86 kernel on a non-NX SMP x86 box and on an NX UP box,
on which i've also tested a simulated SMP trampoline, it all works fine. 

- add infrastructure to enable/disable executability of kernel pages

- make the SMP trampoline page executable.

This is a rather old patch which re-orders the teardown of PCMCIA
network devices.  Current device drivers remove the IO mappings,
interrupts, and free any PCMCIA windows before they unregister
themselves from the network layer.

This patch ensures that we first unregister from the network layer
before performing any teardown of resources or windows.

Note: the only card which has been tested in this patch is pcnet_cs.

Several network drivers have checks that they are only built with -O.
This breaks checking with sparse and other tools, and seems like a holdover from
when drivers were built out of tree and the kernel build system was less stable.
This patch gets rid of these.
