As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.
Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.
Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.
To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

We shouldn't use changed_flags when configuring the packet filter,
we work directly with the total_flags which is safe enough since
we already check if something has changed after we applied our
packet filtering flag rules.
Also make sure that when the packet filter is scheduled, the
rt2x00dev->interface.filter is cleared to make sure the drivers
will update the packet filter instead of failing at the check:
*total_flags == rt2x00dev->interface.filter

This needlessly wakes up processes listening for wireless events many

With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.
Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.
The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.

Honor the advertisement bitmask from ethtool. We used to always

changed things around so that ethtool speed settings were strictly
followed. Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg
in the advertising field (and maybe it shouldn't have to). I'd vote
that it should be fixed there, but it should also be added here just in
case someone using ethtool ioctls in their own application gets what

The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is

Ensure the PHY_HALTED state is not entered with the IRQ asserted as it
could lead to an interrupt loop.
There is a small window in phy_stop(), where the state of the PHY machine
indicates it has been halted, but its interrupt output might still be
unmasked. If an interrupt goes active right at this moment it will loop as
the phy_interrupt() handler exits immediately with IRQ_NONE if the halted
state is seen. It is unsafe to extend the phydev spinlock to cover
phy_interrupt(). It is safe to swap the order of the actions though as all
the competing places to unmask the interrupt output of the PHY, which are
phy_change() and phy_timer() are already covered with the lock as is the
sequence in question.

Keep track of disable_irq_nosync() invocations and call enable_irq() the
right number of times if work has been cancelled that would include them.
Now that the call to flush_work_keventd() (problematic because of
rtnl_mutex being held) has been replaced by cancel_work_sync() another
issue has arisen and been left unresolved. As the MDIO bus cannot be
accessed from the interrupt context the PHY interrupt handler uses
disable_irq_nosync() to prevent from looping and schedules some work to be
done as a softirq, which, apart from handling the state change of the
originating PHY, is responsible for reenabling the interrupt. Now if the
interrupt line is shared by another device and a call to the softirq
handler has been cancelled, that call to enable_irq() never happens and the
other device cannot use its interrupt anymore as its stuck disabled.
I decided to use a counter rather than a flag because there may be more
than one call to phy_change() cancelled in the queue -- a real one and a
fake one triggered by free_irq() if DEBUG_SHIRQ is used, if nothing else.
Therefore because of its nesting property enable_irq() has to be called the
right number of times to match the number disable_irq_nosync() was called
and restore the original state. This DEBUG_SHIRQ feature is also the
reason why free_irq() has to be called before cancel_work_sync().
While at it I updated the comment about phy_stop_interrupts() being called
from `keventd' -- this is no longer relevant as the use of
cancel_work_sync() makes such an approach unnecessary. OTOH a similar
comment referring to flush_scheduled_work() in phy_stop() still applies as
using cancel_work_sync() there would be dangerous.
Checked with checkpatch.pl and at the run time (with and without
DEBUG_SHIRQ).

Use spin_lock_bh()/spin_unlock_bh() for the phydev lock throughout as it
is used in phy_timer() that is called as a softirq and all the other
operations may happen in the user context.
There has been a change recently that did such a conversion for some of the
operations on the lock, but some have been left intact. Many of them,
perhaps all, may be called in the user context and I was able to trigger
recursive spinlock acquisition indeed, so I think for the sake of long-term
maintenance it is best to convert them all, even if unnecessarily for one
or two -- better safe than sorry.
Perhaps one in phy_timer() could actually be skipped as only called as a
softirq -- I can send an update if that sounds like a good idea.

This patch fixes an apparent potential null dereference bug where we
dereference dev before a null check. This patch simply remvoes the
can't-happen test for a null pointer.

In xl_freemem(), if dev_if is NULL, the line
struct xl_private *xl_priv =(struct xl_private *)dev->priv;
will cause a NULL pointer dereference.
(akpm: don't try to fix it: just delete the pointless test-for-null)

These driver changes incorporate the proposed PCI-X / PCI-Express read byte
count interface. Reading and setting those valuse doesn't take place
"manually", instead wrapping functions are called to allow quirks for some
PCI bridges.

A driver model and phylib update. It includes the following changes:
1. Removal of unused module options.
2. Phylib support and the resulting removal of generic bits for handling
the PHY.
3. Proper reserving of device resources and using ioremap()ped handles
to access MAC registers rather than platform-specific macros.
4. Handling of the device using the driver model.

Reorder initialization of the DMA channels and the interface. Before there
was a time window when the interface was enabled before DMA was enabled.
Also, now there will always be RX buffers available at the time the
MAC interface is enabled, to avoid temporary out-of-buffer errors for the
very first packets (on busy networks).
