fdf3480032 Staging: wlags49_h2: reading past the end of array
The original code had some confusion about the dimensions of the array.
It should have been an array of 2 element arrays but it was declared as
an array of 50 element arrays.

The limitter on the outside array should have been
ARRAY_SIZE(chan_freq_list) or 26 but instead 50 was used.  It meant that
we read past the end.  It's probably harmless but it's obviously worth
fixing.

f7738eda21 Staging: rtl8192u: fix some memory corruption
When we received a command we incremented a stat counter depending on
the type of message.  The problem is there were 8 types of commands but
there were only 4 counters allocated so it corrupted memory past the
end of the rxcmdpkt[] array.

The fix is just to remove the counters because they aren't used.

Until now all channels have had read/write attributes. This patch

output devices, write it!)

v2 introduces separate elements for processed and raw thus removing

5ccb3adbd7 staging:iio: add a raw and processed elements to info_mask
This will allow us to have drivers where the channel value
may not be read or written but other information is available.
Also adds the ability to have both processed and raw access
to a given channel, though in most cases this doesn't make
sense.

Ultimately will lead to simpler code by allowing us to drop
the special case handling for the value reading cases.

af6d17cdc8 pch_uart: Fix dma channel unallocated issue
This driver anticipates pch_uart_verify_port() is not called
during installation.
However, actually pch_uart_verify_port() is called during
installation.
As a result, memory access violation occurs like below.

0. initial value: use_dma=0
1. starup()
    - dma channel is not allocated because use_dma=0
2. pch_uart_verify_port()
    - Set use_dma=1
3. UART processing acts DMA mode because use_dma=1
     - memory access violation occurs!

This patch fixes the issue.

Solution:
Whenever pch_uart_verify_port() is called and then
dma channel is not allocated, the channel should be allocated.

22b4a4f22d tcp: fix retransmit of partially acked frames
Alexander Beregalov reported skb_over_panic errors and provided stack
trace.

I occurs commit a21d45726a (tcp: avoid order-1 allocations on wifi and
tx path) added a regression, when a retransmit is done after a partial
ACK.

tcp_retransmit_skb() tries to aggregate several frames if the first one
has enough available room to hold the following ones payload. This is
controlled by /proc/sys/net/ipv4/tcp_retrans_collapse tunable (default :
enabled)

Problem is we must make sure _pskb_trim_head() doesnt fool
skb_availroom() when pulling some bytes from skb (this pull is done when
receiver ACK part of the frame).

0db7bd8ca0 xz: Enable BCJ filters on SPARC and 32-bit x86
The BCJ filters were meant to be enabled already on these
archs, but the xz_wrap.sh script was buggy. Enabling the
filters should give smaller kernel images.

xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect
the architecture. That way it doesn't need to care about the
subarchs (like i386 vs. x86_64) since the BCJ filters don't
care either.

2fbe2bf1fd EHCI: always clear the STS_FLR status bit
This patch (as1544) fixes a problem affecting some EHCI controllers.
They can generate interrupts whenever the STS_FLR status bit is turned
on, even though that bit is masked out in the Interrupt Enable
register.

Since the driver doesn't use STS_FLR anyway, the patch changes the
interrupt routine to clear that bit whenever it is set, rather than
leaving it alone.
