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

There's a check saying

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.

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 removes the interruptible sleep, because we don't really need it.

As the hostap driver was converted to use net_device_ops, a mistake was
made in hostap_main.c (commit 5ae4efbc).
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.

When we close a file, we remove preallocated blocks from it. But this
truncation was not protected by i_mutex and thus it could have raced with a
write through a different fd and cause crashes or even filesystem corruption.
Signed-off-by: Jan Kara <jack@suse.cz>

So far we preallocated blocks also for directories but that brings a
problem, when to get rid of preallocated blocks we don't need. So far
we removed them in udf_clear_inode() which has a disadvantage that
1) blocks are unavailable long after writing to a directory finished
   and thus one can get out of space unnecessarily early
2) releasing blocks from udf_clear_inode is problematic because VFS
   does not expect us to redirty inode there and it also slows down
   memory reclaim.

So preallocate blocks only for regular files where we can drop preallocation
in udf_release_file.
