This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo
object for events and a swapping buffer scheme for the command response to
preserve the zero-copy semantics of the CF driver and keep memory usage low.
The main thread should only ever touch the buffer indexed by priv->resp_idx,
while the interface code is free to write to the second buffer, then swap
priv->resp_idx under the driver spinlock. The firmware specs only permit
one in-flight command, so there will only ever be one command response to
process at a time.

In rt2x00lib_intf_scheduled_iter() we use the hw->beacon_update()
callback function. This means that it should behave similarly as mac80211
when that uses the function.
This means that the skb should only be freed when beacon_update() has failed,
otherwise the driver is the owner and is responsible for freeing the buffer.

This is basically means that a net is set for a new device, but
actually also involves two more steps:
1. mark the tun device as "local", i.e. do not allow for it to
move across namespaces.
This is done so, since tun device is most often associated to some
file (and thus to some process) and moving the device alone is not
valid while keeping the file and the process outside. The need in
ability to move a detached persistent device is to be investigated
later.
2. get the tun device's net when tun becomes attached and put one
when it becomes detached.
This is needed to handle the case when a task owning the tun dies,
but a files lives for some more time - in this case we must not
allow for net to be freed, since its exit hook will spoil that file's
private data by unregistering the tun from under tun_chr_close.

This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.
Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.

Since 0bcc181618 (netconsole: Support
dynamic reconfiguration using configfs), the netconsole is always
registered, regardless of whether the user actually specified a
netconsole configuration on the command line.
However because netconsole has CON_PRINTBUFFER set, when it is
registered it causes the printk buffer to be replayed to all consoles.
When there is no netconsole configured this is a) pointless, and b)
somewhat annoying for the user of the existing console.
So instead we should only set CON_PRINTBUFFER if there is a netconsole
configuration found on the command line. This retains the existing
behaviour if a netconsole is setup by the user, and avoids spamming
other consoles when we're only registering for the dynamic
netconsole case.

The driver stores the PCI resource addresses into 'unsigned long' variable
before calling ioremap_nocache() on them. This warrants kernel oops when the
registers are accessed on PPC 44x platforms which (being 32-bit) have PCI
memory space mapped beyond 4 GB.
The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion that
the PCI memory resource is mapped below 4 GB, but arch/powerpc/ code got rid
of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

This critical patch fixes a mac address issue recently introduced. If the
device's mac address was in correct order and the flag
NVREG_TRANSMITPOLL_MAC_ADDR_REV was set, during nv_remove the flag would get
cleared. During next load, the mac address would get reversed because the
flag is missing.
As it has been indicated previously, the flag is cleared across a low power
transition. Therefore, the driver should set the mac address back into the
reversed order when clearing the flag.
Also, the driver should set back the flag after a low power transition to
protect against kexec command calling nv_probe a second time.

If print_mac() is used inside of a pr_debug() the compiler
can't see that the call is redundant so still performs it
even of pr_debug() ends up being a nop.
So don't use print_mac() in such cases in hot code paths,
use MAC_FMT et al. instead.
As noted by Joe Perches, pr_debug() could be modified to
handle this better, but that is a change to an interface
used by the entire kernel and thus needs to be validated
carefully. This here is thus the less risky fix for
