In omap_dma_start_desc the vdesc->node is removed from the virt-dma
framework managed lists (to be precise from the desc_issued list).
If a terminate_all comes before the transfer finishes the omap_desc will
not be freed up because it is not in any of the lists and we stopped the
DMA channel so the transfer will not going to complete.
There is no special sequence for leaking memory when using cyclic (audio)
transfer: with every start and stop of a cyclic transfer the driver leaks
struct omap_desc worth of memory.
Free up the allocated memory directly in omap_dma_terminate_all() since the
framework will not going to do that for us.

If edma_terminate_all() was called while a transfer was running (i.e. after
edma_execute() but before edma_callback()) the echan->edesc was not freed.
This was due to the fact that a running transfer is on none of the
vchan lists: desc_submitted, desc_issued, desc_completed (edma_execute()
removes it from the desc_issued list), so the vchan_dma_desc_free_list()
called at the end of edma_terminate_all() didn't find it and didn't free it.
This bug was found on an AM1808 based hardware (very similar to da850evm,
however using the second MMC/SD controller), where intense operations on the SD
card wasted the device 128MB RAM within a couple of days.
Peter Ujfalusi:
The issue is even more severe since it affects cyclic (audio) transfers as
well. In this case starting/stopping audio will results memory leak.

The FEC modules used on i.MX28 and newer have a register to tune the MDIO
output hold time that should be at least 10 ns. Up to now this value was not
explicitly set and so resulted in less hold time if the fec clock was
faster than 100 MHz.
This was noticed on an i.MX28 machine that uses an input clock of ~150
Mhz which resulted in unreliable communication with a Marvell switch.

tcp_v6_fill_cb() will be called twice if socket's state changes from
TCP_TIME_WAIT to TCP_LISTEN. That can result in control buffer data
corruption because in the second tcp_v6_fill_cb() call it's not copying
IP6CB(skb) anymore, but 'seq', 'end_seq', etc., so we can get weird and
unpredictable results. Performance loss of up to 1200% has been observed
in LTP/vxlan03 test.
This can be fixed by copying inet6_skb_parm to the beginning of 'cb'
only if xfrm6_policy_check() and tcp_v6_fill_cb() are going to be
called again.

With the current code, ids are removed too early.
Suppose you have an ipip interface that stands in the netns foo and its link
part in the netns bar (so the netns bar has an nsid into the netns foo).
Now, you remove the netns bar:
- the bar nsid into the netns foo is removed
- the netns exit method of ipip is called, thus our ipip iface is removed:
=> a netlink message is sent in the netns foo to advertise this deletion
=> this netlink message requests an nsid for bar, thus a new nsid is
allocated for bar and never removed.
We must remove nsids when we are sure that nobody will refer to netns currently
cleaned.

With a monolithic GICv3, redistributors are addressed using a linear
number, while a distributed implementation uses physical addresses.
When encoding a target address into a command, we strip the lower
16 bits, as redistributors are always 64kB aligned. This works
perfectly well with a distributed implementation, but has the
silly effect of always encoding target 0 in the monolithic case
(unless you have more than 64k CPUs, of course).
The obvious fix is to shift the linear target number by 16 when
computing the target address, so that we don't loose any precious
bit.

QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command
can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END.
For eg, in the first load eqid can be from 100 to 300.
In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is
1000).
The driver was assuming them to always start from EQ(IQFLINT)_START till
MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash.
Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for
these structures.

cdc_ncm disagrees with usbnet about how much framing overhead should
be counted in the tx_bytes statistics, and tries 'fix' this by
decrementing tx_bytes on the transmit path. But statistics must never
be decremented except due to roll-over; this will thoroughly confuse
user-space. Also, tx_bytes is only incremented by usbnet in the
completion path.
Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a
tx_bytes delta along with the tx_packets count.

Currently the usbnet core does not update the tx_packets statistic for
drivers with FLAG_MULTI_PACKET and there is no hook in the TX
completion path where they could do this.
cdc_ncm and dependent drivers are bumping tx_packets stat on the
transmit path while asix and sr9800 aren't updating it at all.
Add a packet count in struct skb_data so these drivers can fill it
in, initialise it to 1 for other drivers, and add the packet count
to the tx_packets statistic on completion.

If the user supplies EDID through firmware or debugfs override, the
driver callbacks are bypassed and the connector ELD does not get
updated, and audio fails. Set ELD for firmware and debugfs EDIDs too.
There should be no harm in gratuitously doing this for non HDMI/DP
connectors, as it's still up to the driver to use the ELD, if any.

locks_delete_lock_ctx() is called inside the loop, so we
should use list_for_each_entry_safe.
Fixes: 8634b51f6ca2 (locks: convert lease handling to file_lock_context)

Now GPIO syscon driver produces bunch of warnings during the
boot of Kesytone 2 SoCs:
gpio-syscon soc:keystone_dsp_gpio@02620240: can't read the dir register offset!
gpio-syscon soc:keystone_dsp_gpio@2620244: can't read the dir register offset!
This message unintentionally was added using dev_err(), but its
actual log level is debug, because third cell of "ti,syscon-dev" is
optional.
Hence change it to dev_dbg() as it should be.
This patch fixes commit:
5a3e3f8 ("gpio: syscon: retriave syscon node and regs offsets from dt")
