The lirc TX functionality expects the process which writes (TX) data to
the lirc dev to sleep until the actual data has been transmitted by the
hardware.
Since the same timeout calculation is duplicated in more than one driver
(and would have to be duplicated in even more drivers as they gain TX
support), it makes sense to move this timeout calculation to the lirc
layer instead.
At the same time, centralize some of the sanity checks.

When the TEI bit is raised, we should not trust any of the contents of
the packet in question, including but not limited to its PID number.
Considering that we don't trust the PID number of this packet, we should
not proceed to check the packet counter (if dvb_demux_tscheck is set).
We should expect to see at least one discontinuity after a bad packet is
received, so any time a TEI is detected, a following TS packet counter
mismatch is to be expected.
There is no real reason to ever allow bad packets to pass through the
kernel demux, other than for purposes of attempting error correction via
software or statistical information.
However, since we have always passed these bad packets though the demux,
we should not change this default behavior.
Without altering module options, this patch merely prevents the
TS packet counter check on packets containing a raised TEI.
If module option dvb_demux_feed_err_pkts is set to 0, the kernel demux
will drop these error packets entirely, preventing any possibility of
corruption caused by userspace programs that are expecting valid data.

These double "const" were introduced in v2.6.37-rc1~64^2~464 (V4L/DVB:
drivers/media: Make static data tables and strings const, 2010-08-25).

It is possible for asynchronous RDMA_CM_EVENT_ESTABLISHED events to be
generated with ctx->uid == 0, because ucma_set_event_context() copies
ctx->uid to the event structure outside of ctx->file->mut. This leads
to a crash in the userspace library, since it gets a bogus event.
Fix this by taking the mutex a bit earlier in ucma_event_handler.

This is the driver for the IR transmitter diode found on the Nokia
N900 (also known as RX51) device. The driver is mostly the same as
found in the original 2.6.28 based kernel that comes with the device.
The following modifications have been made compared to the original
driver version:
- Adopt to the changes that has happen in the kernel during the past
five years, such as the change in the include paths
- The OMAP DM-timers require much more care nowadays. The timers need
to be enabled and disabled or otherwise many actions fail. Timers
must not be freed without first stopping them or otherwise the timer
cannot be requested again.
The code has been tested with sending IR codes with N900 device
running Debian userland. The device receiving the codes was Anysee
DVB-C USB receiver.

This callback were meant to allow overriding a FE callback, before its
call, but it is not really needed, as the callback can be intercepted
after tuner attachment.
Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5
application will produce different effects than a DVBv3 one.

Because FIQ handlers get copied straight into the vectors page to
the FIQ vector entry point, FIQ handlers in a Thumb-2 kernel must
start in Thumb-2. A Thumb-2 kernel enters all exception vectors in
Thumb-2.
This patch adapts the mxc SSI FIQ code suitable for a Thumb-2
kernel.
The code contained use of r13 (sp) which isn't allowed in Thumb-2.
r11 and r13 have been swapped throughout the file to work around
this.
Currently, the way that the function to be copied is located using
labels is a bit ugly: we cannot annotate the FIQ handler properly
as a Thumb-2 function, because this would set bit 0 of the label
address seen by the linker, causing off-by-one errors when copying
the function. Ideally, the copy would be done with fncpy(), but
this would require changes to the common set_fiq_handler()
function. For now, we don't touch this.
References to locally-defined global symbols with adr and ldr may
not be accepted by the assembler in Thumb-2. Local shadow symbols
are added to work around this.

With this patch the corresponding functions return the BSS_CHANGED_BEACON flag when a beacon update is necessary.
Also it makes mesh_accept_plinks_update the common place to update the accepting_plinks flag.
mesh_accept_plinks_update is called upon plink change and also periodically from ieee80211_mesh_housekeeping.

ath_rx_tasklet() calls ath9k_rx_skb_preprocess() and ath9k_rx_skb_postprocess()
in a loop over the received frames. The decrypt_error flag is
initialized to false
just outside ath_rx_tasklet() loop. ath9k_rx_accept(), called by
ath9k_rx_skb_preprocess(),
only sets decrypt_error to true and never to false.
Then ath_rx_tasklet() calls ath9k_rx_skb_postprocess() and passes
decrypt_error to it.
So, after a decryption error, in ath9k_rx_skb_postprocess(), we can
have a leftover value
from another processed frame. In that case, the frame will not be marked with
RX_FLAG_DECRYPTED even if it is decrypted correctly.
When using CCMP encryption this issue can lead to connection stuck
because of CCMP
PN corruption and a waste of CPU time since mac80211 tries to decrypt an already
deciphered frame with ieee80211_aes_ccm_decrypt.
Fix the issue initializing decrypt_error flag at the begging of the
ath_rx_tasklet() loop.
