====================
pull request: bluetooth 2015-07-15
Here's a regression fix for Broadcom Bluetooth adapters found at least
in certain Apple laptops. The issue was introduced in 4.1 so there's the
appropriate "Cc: stable" entry for it.

The ->drop() is supposed to return the number of bytes it dropped,
however fq_codel_drop() returns the index of the flow where it drops
a packet from.
Fix this by introducing a helper to wrap fq_codel_drop().

Commit 79901317ce80 ("n_tty: Don't flush buffer when closing ldisc"),
first merged in kernel release 3.10, caused the following regression
in the Gigaset M101 driver:
Before that commit, when closing the N_TTY line discipline in
preparation to switching to N_GIGASET_M101, receive_room would be
reset to a non-zero value by the call to n_tty_flush_buffer() in
n_tty's close method. With the removal of that call, receive_room
might be left at zero, blocking data reception on the serial line.
The present patch fixes that regression by setting receive_room
to an appropriate value in the ldisc open method.

Currently F-RTO may repeatedly send new data packets on non-recurring
timeouts in CA_Loss mode. This is a bug because F-RTO (RFC5682)
should only be used on either new recovery or recurring timeouts.
This exacerbates the recovery progress during frequent timeout &
repair, because we prioritize sending new data packets instead of
repairing the holes when the bandwidth is already scarce.
Fix it by correcting the test of a new recovery episode.

When we calculate the checksum on the recv path, we store the
result in the skb as an optimisation in case we need the checksum
again down the line.
This is in fact bogus for the MSG_PEEK case as this is done without
any locking. So multiple threads can peek and then store the result
to the same skb, potentially resulting in bogus skb states.
This patch fixes this by only storing the result if the skb is not
shared. This preserves the optimisations for the few cases where
it can be done safely due to locking or other reasons, e.g., SIOCINQ.

Shared skbs must not be modified and this is crucial for broadcast
and/or multicast paths where we use it as an optimisation to avoid
unnecessary cloning.
The function skb_recv_datagram breaks this rule by setting peeked
without cloning the skb first. This causes funky races which leads
to double-free.
This patch fixes this by cloning the skb and replacing the skb
in the list when setting skb->peeked.

Similarly as in commit 4f7d2cdfdde7 ("rtnetlink: verify IFLA_VF_INFO
attributes before passing them to driver"), we have a double nesting
of netlink attributes, i.e. IFLA_VF_PORTS only contains IFLA_VF_PORT
that is nested itself. While IFLA_VF_PORTS is a verified attribute
from ifla_policy[], we only check if the IFLA_VF_PORTS container has
IFLA_VF_PORT attributes and then pass the attribute's content itself
via nla_parse_nested(). It would be more correct to reject inner types
other than IFLA_VF_PORT instead of continuing parsing and also similarly
as in commit 4f7d2cdfdde7, to check for a minimum of NLA_HDRLEN.

If a failure occurs during probe, brcmstb_gpio_remove() is called. In
remove, we call platform_get_drvdata(), but at the time of failure in
the probe the driver data hadn't yet been set which leads to a NULL
ptr dereference in the remove's list_for_each. Call
platform_set_drvdata() and set up list head right after allocating the
priv struct to both avoid the null pointer dereference that could
occur today. To guard against potential future changes, check for
null pointer in remove.

The end of jfs_rename(), which is also used by the error paths,
included a call to IWRITE_UNLOCK(new_ip) after labels out1, out2
and out3. If we come in through these labels, IWRITE_LOCK() has not
been called yet.
In moving that call to the correct spot, I also moved some
exceptional truncate code earlier as well, since the early error
paths don't need to deal with it, and I renamed out4: to out_tx: so
a future patch by Jan Kara doesn't need to deal with renumbering or
confusing out-of-order labels.

Pull final init.h/module.h code relocation from Paul Gortmaker:
"With the release of 4.2-rc2 done, we should not be seeing any new code
added that gets upset by this small code move, and we've banked yet
another complete week of testing with this move in place on top of

Given that, I'd like to put it in now so that people formulating new
work for 4.3-rc1 will be exposed to the ever so slightly stricter (but
sensible) requirements wrt. whether they are needing init.h vs.
module.h macros, even if they are not using linux-next.
The diffstat of the move is slightly asymmetrical due to needing to
leave behind a couple #ifdef in the old location and add the same ones
to the new location, but other than that, it is a 1:1 move, complete
with the module_init/exit trailing semicolon that we can't fix. That
is, until/unless someone does a tree-wide sed fix of all the
approximately 800 currently in tree users relying on it"

Fix the start address calculation when overlay is partially off screen.
fb->bits_per_pixel is not set for YUV formats, and is always zero, which
led to the first component always starting at zero.
Use drm_format_plane_cpp() instead.
This also revealed a problem in that YUYV formats toggle the U/V data
for odd pixel start address offsets. We try to rectify that by
toggling the U/V swap, which for the most part works, but seemingly
introduces a flicker for one scan frame of swapped U/V.
However, these changes result in an overall improvement.

Fix the gem object freeing after a partial import of a dma buffer,
eg, one which has been imported, but not mapped. This was provoking
a warning from the dma_buf code.

The Armada overlay plane wasn't being properly cleaned up as it was
missing a call to drm_plane_cleanup(). It also wasn't freeing the
right type of pointer (although we were still freeing the right
pointer value.)

Nothing was waking up the overlay plane wait queue, so we were fully
reliant on the HZ/25 wait timing out to make progress. Fix the lack
of wake-up.
We were also mis-handling the wait_event_timeout() return value - this
returns an unsigned integer of the remaining time, or zero on timeout
and the condition evaluated false. Checking this for less than zero
is not sane.

Commit 5ef7bbb09f7b ("perf tools: Allow to specify custom linker
command") was meant to enable usage non $(CROSS_COMPILE)ld linker during
perf building.
But implementation didn't take into account the fact that LD is a
pre-defined variable in GNU Make. I.e. it is always defined.
Which means there's no point to check "LD ?= ..." because it will never
succeed.
And so LD will be either that explicitly passed to make like this:
------->8-------
make LD=path_to_my_ld ...
------->8-------
or default value, which is host's "ld".
Latter leads to failure of cross-linkage because instead of cross linker
"$(CROSS_COMPILE)ld" host's "ld" is used.
Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld
with user defined LD on command-line.
As a reference was used implementation in "tools/lib/traceevent/Makefile".
Build tested for x86_64 and ARC.
Thanks Jiri for this hint.

Move the checking for HAVE_SYNC_COMPARE_AND_SWAP_SUPPORT for AUX area mmaps
until after checking if such mmaps are used anyway.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fix from Arnaldo Carvalho de Melo:
- Fix 'perf report' and 'perf top' handling of the '--dsos DSO-LIST',
'--comms COMM-LIST' and '--symbols SYM-LIST' command line options,
that were segfaulting due to not considering those lists as filters
in the hists browser TUI code. (Arnaldo Carvalho de Melo)

Audio-in was incorrectly routed to Line In. It should be Mic3L as per
schematic.
Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.
I see voltage of 2.475v across GND and micbias.
With these changes, I can record audio with a pair of proliferate TRRS earbuds.

CONFIG_HAVE_ARM_SCU only gets selected if CONFIG_SMP is selected in an OMAP
system, however AM43XX needs this option regardless of CONFIG_SMP and also
for an AM43XX only build as it is important for controlling power in the SoC.
Without this we cannot suspend the CPU for SoC suspend or cpuidle. The
ARM Cortex A9 needs SCU CPU Power Status bits to be set to off mode in order
for the PRCM to transition the MPU to low power modes.

drm: add support for tiled/compressed/etc modifier in addfb2
Missed the structure packing/alignment problem where 64-bit
members were added after the odd number of 32-bit ones. This
makes the compiler produce structures of different sizes under
32- and 64-bit x86 targets and makes the ioctl need explicit
compat handling.
