The current verison of b43 uses "b43_phyop_switch_analog_generic" for A,
G and LP phys.
According to the spec, this is the wrong behaviour for the LP PHY
(see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore )
While no problems on the x86 plattform where seen, this leads to a crash
on the BCM5354 SoC (MIPS 32 LE plattform).
This patch implements the analog switch for LP PHYs according to the
specs. It fixes the crash

This adds support for verbose runtime statistics.
It defaults to off and must be enabled in debugfs, if desired.
The first measurement may be incorrect, because statistics are not cleared
after they got enabled through debugfs.

There's a bug in 4965 powersave that appears to
be related to the way it keeps track of its data
during sleep, but we haven't found it yet. Due to
that, using powersave may spontaneously cause the
device to SYSASSERT when transitioning from sleep
to wake. Therefore, disable powersave for 4965,
until (if ever, unfortunately) we can identify
and fix the problem.
Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982
which was closed, but now has re-appeared with
IDLE mode, which probably means we never really
fixed it.

RX handling maintains a few lists that keep track of the RX buffers.
Buffers move from one list to the other as they are used, replenished, and
again made available for usage. In one such instance, when a buffer is used
it enters the "rx_used" list. When buffers are replenished an skb is
attached to the buffer and it is moved to the "rx_free" list. The problem
here is that the buffer is first removed from the "rx_used" list _before_ the
skb is allocated. Thus, if the skb allocation fails this buffer remains
removed from the "rx_used" list and is thus lost for future usage.
Fix this by first allocating the skb before trying to attach it to a list.
We add an additional check to not do this unnecessarily.

This fixes a resume failure where a signal is pending on resume
so the firmware upload fails.
This removes the interruptible sleep, because we don't really need it.
In the worst case (with broken firmware) the sleep loop will take 1 second.
In the common case (working firmware), it will only take a few milliseconds.
So we don't really need to be interruptible.

As the hostap driver was converted to use net_device_ops, a mistake was
made in hostap_main.c (commit 5ae4efbcd2611562a8b93596be034e63495706a5).
Originally, the tx_queue_len was set to 0 for every other interface than
HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to
0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous
behavior makes the driver to drop all packets in AP mode.
Change the way 0 is assigned to tx_queue_len according to the original
logic.

Originally, walk_memory_resource() was introduced to traverse all memory
of "System RAM" for detecting memory hotplug/unplug range. For doing so,
flags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for
memory hotplug.
But for using other purpose, /proc/kcore, this may includes some firmware
area marked as IORESOURCE_BUSY | IORESOUCE_MEM. This patch makes the
check strict to find out busy "System RAM".
Note: PPC64 keeps their own walk_memory_resouce(), which walk through
ppc64's lmb informaton. Because old kclist_add() is called per lmb, this
patch makes no difference in behavior, finally.
And this patch removes CONFIG_MEMORY_HOTPLUG check from this function.
Because pfn_valid() just show "there is memmap or not* and cannot be used
for "there is physical memory or not", this function is useful in generic
to scan physical memory range.

gcc permitting variable length arrays makes the current construct used for
BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the
controlling expression isn't really constant. Instead, this patch makes
it so that a bit field gets used here. Consequently, those uses where the
condition isn't really constant now also need fixing.
Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases
MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if
the expression is compile time constant (__builtin_constant_p() yields
true), the array is still deemed of variable length by gcc, and hence the
whole expression doesn't have the intended effect.

This is an alternate solution to the EEM 'sentinel' CRC valiation issue.
CDC EEM allows using a 'sentinel' ethernet frame CRC of 0xdeadbeef in
place of a real CRC. The 'sentinel' value is transmitted in big-endian
order whereas the normal CRC is little-endian. This patch handles both
cases appropriately.

Usbnet framework assumes USB hardware doesn't handle zero length
packets, but SMSC LAN95xx requires these to be sent for correct
operation.
This patch fixes an easily reproducible tx lockup when sending a frame
that results in exactly 512 bytes in a USB transmission (e.g. a UDP
frame with 458 data bytes, due to IP headers and our USB headers). It
adds an extra flag to usbnet for the hardware driver to indicate that
it can handle and requires the zero length packets.
This patch should not affect other usbnet users, please also consider
for -stable.

kaweth_control() never frees the buffer that it allocates for the USB
control message. Test case:
while :; do ifconfig eth2 down ; ifconfig eth2 up ; done
This is a tiny buffer so it is a slow leak. If you want to speed up the
process, you can change the allocation size to e.g. 16384 bytes, and it
will consume several megabytes within a few minutes.
