This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.
This patch also fixes some of the asm/prom.h ordering issues. It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus. This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.
Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim. At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.

Now that the device tree node pointer has been moved out of struct
of_device and into the common struct device, there isn't anything
unique about of_device anymore. In fact, there isn't much need
for a separate of_bus when all busses have access to OF style
probing.
arch/powerpc and arch/microblaze are moving away from using the of_bus
and using the regular platform bus instead for mmio devices. This
patch makes of_device the same as platform_device as a stepping stone
in migrating of_platform_drivers over to the platform bus.

This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure. The reason
for this change is to unify the struct of_device definition amongst
all the architectures. It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.
A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).
This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device. After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.
This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.

au1000_eth uses firmware calls to get a valid MAC address, and changes
it depending on platform device id. This patch moves this logic out of
the driver into the platform device registration part, where boards with
supported chips can use whatever firmware interface they need; the default
implementation maintains compatibility with existing, YAMON-based firmware.

niu_get_ethtool_tcam_all() assumes that its output buffer is the right
size, and warns before returning if it is not. However, the output
buffer size is under user control and ETHTOOL_GRXCLSRLALL is an
unprivileged ethtool command. Therefore this is at least a local
denial-of-service vulnerability.
Change it to check before writing each entry and to return an error if
the buffer is already full.
Compile-tested only.

This fixes a bug introduced in commit
de847272149365363a6043a963a6f42fb91566e2
"3c59x: Use fine-grained locks for MII and windowed register access".
vortex_interrupt() holds vp->window_lock over multiple register
accesses to reduce locking overhead. However it also needs to call
vortex_error() sometimes, and that uses the regular functions for
access to windowed registers, which will try to acquire window_lock
again.
Therefore, drop window_lock around the call to vortex_error() and set
the window afterward reacquiring the lock. Since vortex_error() may
call vortex_rx(), which *does* require its caller to hold window_lock,
lift that call up into vortex_interrupt(). This also removes the
potential for calling vortex_rx() on a later-generation NIC.

The time_before_eq()/time_after_eq() functions operate on unsigned
long and only work if the difference between the two compared values
is smaller than half the range of unsigned long (31 bits on i386).
Some of the variables (slave->jiffies, dev->trans_start, dev->last_rx)
used by bonding store a copy of jiffies and may not be updated for a
long time. With HZ=1000, time_before_eq()/time_after_eq() will start
giving bad results after ~25 days.
jiffies will never be before slave->jiffies, dev->trans_start,
dev->last_rx by more than possibly a couple ticks caused by preemption
of this code. This allows us to detect/prevent these overflows by
replacing time_before_eq()/time_after_eq() with time_in_range().

The ONLINE registers can return 0xFFFFFFFF on more than one
occassion. On systems that care, reading these registers could
lead to problems.
So the new code decides that the ASIC has encountered and error
by reading the UE_STATUS_LOW/HIGH registers. AND them with
the mask values and a non-zero result indicates an error.

vortex_ioctl() was grabbing vortex_private::lock around its call to
generic_mii_ioctl(). This is no longer necessary since there are more
specific locks which the mdio_{read,write}() functions will obtain.
Worse, those functions do not save and restore IRQ flags when locking
the MII state, so interrupts will be enabled when generic_mii_ioctl()
returns.
Since there is currently no need for any function to call
mdio_{read,write}() while holding another spinlock, do not change them
to save and restore IRQ flags but remove the specification of ordering
between vortex_private::lock and vortex_private::mii_lock.

There's something very important I forgot to tell you.
What?
Don't cross the GRO streams.
Why?
It would be bad.
I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?
Try to imagine all the Internet as you know it stopping instantaneously
and every bit in every packet swapping at the speed of light.
Total packet reordering.
Right. That's bad. Okay. All right. Important safety tip. Thanks, Hubert
The simplest way to stop this is just avoid doing GRO on the second port.
Very few Marvell boards support two ports per ring, and GRO is just
an optimization.

The 5 GHz CTL indexes were not being read for all hardware
devices due to the masking out through the CTL_MODE_M mask
being one bit too short. Without this the calibrated regulatory
maximum values were not being picked up when devices operate
on 5 GHz in HT40 mode. The final output power used for Atheros
devices is the minimum between the calibrated CTL values and
what CRDA provides.

The EEPROM is compressed on AR9003, upon decompression
the wrong upper limit was being used for the block which
prevented the 5 GHz CTL indexes from being used, which are
stored towards the end of the EEPROM block. This fix allows
the actual intended regulatory limits to be used on AR9003
hardware.

Michael reported that p54* never really entered power
save mode, even tough it was enabled.
It turned out that upon a power save mode change the
firmware will set a special flag onto the last outgoing
frame tx status (which in this case is almost always the
designated PSM nullfunc frame). This flag confused the
driver; It erroneously reported transmission failures
to the stack, which then generated the next nullfunc.
and so on...

This avoids a NULL pointer dereference as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=625889
When the WARN condition is hit in ieee80211_get_tx_rate, it will return
NULL. So, we need to check the return value and avoid dereferencing it
in that case.

if_sdio's lbs_helper_name and lbs_fw_name against sysfs changes)
introduced new fields into the if_sdio_card structure. It caused
missalignment of the if_sdio_card.buffer field and failure at driver
load time:

A couple issues here:
* Some resources weren't released.
* If alloc_etherdev() failed it would have caused a NULL dereference
because "pep" would be null when we checked "if (pep->clk)".
* Also it's better to propagate the error codes from mdiobus_register()
instead of just returning -ENOMEM.

"pep->pd" isn't checked consistently in this function. For example it's
dereferenced unconditionally on the next line after the end of the if
condition. This function is only called from pxa168_eth_probe() and
pep->pd is always non-NULL so I removed the check.

It is possible that phylib will call adjust_link before returning
from {,of_}phy_connect(), which may cause the following [very rare,
though] oops upon reopening the device:
Unable to handle kernel paging request for data at address 0x0000024c

Here is why. Drivers store phydev in their private structures, e.g.
gianfar driver:
static int init_phy(struct net_device *dev)
{
...
priv->phydev = of_phy_connect(...);
...
}
So that adjust_link could retrieve it back:
static void adjust_link(struct net_device *dev)
{
...
struct phy_device *phydev = priv->phydev;
...
}
If the device has been opened before, then phydev->state is set to
PHY_HALTED (or undefined if the driver didn't call phy_stop()).
Now, phy_connect starts the PHY state machine before returning phydev to
the driver:
phy_start_machine(phydev, NULL);
if (phydev->irq > 0)
phy_start_interrupts(phydev);
return phydev;
The time between 'phy_start_machine()' and 'return phydev' is undefined.
The start machine routine delays execution for 1 second, which is enough
for most cases. But under heavy load, or if you're unlucky, it is quite
possible that PHY state machine will execute before phy_connect()
returns, and so adjust_link callback will try to dereference phydev,
which is not yet ready.
To fix the issue, simply initialize the PHY's state to PHY_READY during
phy_attach(). This will ensure that phylib won't call adjust_link before
phy_start().

If netconsole is in use, there is a possibility for deadlock in 3c59x between
boomerang_interrupt and boomerang_start_xmit. Both routines take the vp->lock,
and if netconsole is in use, a pr_* call from the boomerang_interrupt routine
will result in the netconsole code attempting to trnasmit an skb, which can try
to take the same spin lock, resulting in deadlock.
The fix is pretty straightforward. This patch allocats a bit in the 3c59x
private structure to indicate that its handling an interrupt. If we get into
the transmit routine and that bit is set, we can be sure that we have recursed
and will deadlock if we continue, so instead we just return NETDEV_TX_BUSY, so
the stack requeues the skb to try again later.

iwlwifi: apply filter flags directly
broke 3945 under some unknown circumstances, as
reported by Alex.
Since I want to keep the direct application of
filter flags on iwlagn, duplicate the code into
both 3945 and agn and remove committing the
RXON that broke things from the 3945 version.

For 5000 and 6000g2b series of devices, use long monitor timer to check
stuck tx queues.
.6000g2b series device, it is WiFi/BT combo device, there are some cases,
tx queues are not move for a period of time because the WiFi/BT coex.
.5000 series device, it is being reported firmware got reload more
often than necessary, so extend the timer to avoid un-necessary reload.
