Michael's patch to use the default make rule for linking and the patch
from Rehas to use -m32 if building a 32-bit test-suite on a 64-bit
platform don't work well together.

There's a relatively rare race where we look at the per-cpu preallocated
IDA bitmap, see it's NULL, allocate a new one, and atomically update it.
If the kmalloc() happened to sleep and we were rescheduled to a different
CPU, or an interrupt came in at the exact right time, another task
might have successfully allocated a bitmap and already deposited it.
I forgot what the semantics of cmpxchg() were and ended up freeing the
wrong bitmap leading to KASAN reporting a use-after-free.
Dmitry found the bug with syzkaller & wrote the patch. I wrote the test
case that will reproduce the bug without his patch being applied.

Changing the CFLAGS in the Makefile didn't always lead to a
recompilation because the OFILES didn't depend on the Makefile.
Also, after doing make clean, grep would still complain about
a missing map-shift.h; we need -s as well as -q.

Currently the radix tree test suite doesn't build with toolchains that
use --as-needed by default, for example Ubuntu's:
cc -I. -I../../include -g -O2 -Wall -D_LGPL_SOURCE -fsanitize=address -lpthread -lurcu main.o ... -o main
/usr/bin/ld: regression1.o: undefined reference to symbol 'pthread_join@@GLIBC_2.17'
/lib/powerpc64le-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
This is caused by the custom makefile rules placing LDFLAGS before the
.o files that need the libraries.
We could fix it by using --no-as-needed, or rewriting the custom rules.
But we can also just drop the custom rules and move the libraries to
LDLIBS, and then the default rules work correctly - with the one caveat
that we need to add -fsanitize=address to LDFLAGS because that must be
passed to the linker as well as the compiler.

Currently N_HDLC line discipline uses a self-made singly linked list for
data buffers and has n_hdlc.tbuf pointer for buffer retransmitting after
an error.
The commit be10eb7589337e5defbe214dae038a53dd21add8
("tty: n_hdlc add buffer flushing") introduced racy access to n_hdlc.tbuf.
After tx error concurrent flush_tx_queue() and n_hdlc_send_frames() can put
one data buffer to tx_free_buf_list twice. That causes double free in
n_hdlc_release().
Let's use standard kernel linked list and get rid of n_hdlc.tbuf:
in case of tx error put current data buffer after the head of tx_buf_list.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
"There was some breakage with the changes for jump labels in the 4.11
merge window:
- powerpc broke as jump labels uses the two LSB bits as flags in
initialization.
A check was added to make sure that all jump label entries were 4
bytes aligned, but powerpc didn't work that way for modules. Adding
an alignment in the module linker script appeared to be the best
solution.
- Jump labels also added an anonymous union to access those LSB bits
as a normal long. But because this structure had static
initialization, it broke older compilers that could not statically
initialize anonymous unions without brackets.
- The command line parameter for setting function graph filter broke
the "EMPTY_HASH" descriptor by modifying it instead of creating a
new hash to hold the entries.
- The command line parameter ftrace_graph_max_depth was added to
allow its setting at boot time. It uses existing code and only the
command line hook was added.
This is not really a fix, but as it uses existing code without
affecting anything else, I added it to this release. It was ready
before the merge window closed, but I wanted to let it sit in
linux-next for a couple of days first"
* tag 'trace-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:

This commit adds the device tree description for the Synology DS116 NAS.
It is a one-bay NAS powered by a Marvell Armada 385 at 1.866 GHz. The
device features the following items :
- 1 GB DDR3 RAM
- a 8MB SPI flash
- 2 USB3 ports, power-controlled via a GPIO for each
- 1 gigabit ethernet interface connected over SGMII to a 88e1514 phy
- a single SATA port, power-controlled via a GPIO
- a battery-powered RTC
- one UART connected to the serial console (2mm connector on board)
- the Tx line of the second UART connected to a PIC microcontroller
dealing with beep, reset, power-off and LED blinking (9600 Bps)
- some of the front-panel LEDs are connected to GPIOs, one is directly
connected to the SATA link to report disk activity.
- a GPIO-controlled fan (3 bits for 7 speeds and OFF)
With this DTS, my NAS is 100% functional starting with kernel 4.9.

The interface to configure the LIF in the VSP1 requires adapting the
function prototype for any changes. This makes extending the interface
difficult.
Change the function prototype to pass a structure which can be easily
extended.
This changes the means of disabling the pipeline, by now passing a NULL
configuration rather than passing either a 0 width or height.

The ITS spec says that ITS commands are only processed when the ITS
is enabled (section 8.19.4, Enabled, bit[0]). Our emulation was not taking
this into account.
Fix this by checking the enabled state before handling CWRITER writes.
On the other hand that means that CWRITER could advance while the ITS
is disabled, and enabling it would need those commands to be processed.
Fix this case as well by refactoring actual command processing and
calling this from both the GITS_CWRITER and GITS_CTLR handlers.

Currently we BUG() if we see an ESR_EL2.EC value we don't recognise. As
configurable disables/enables are added to the architecture (controlled
by RES1/RES0 bits respectively), with associated synchronous exceptions,
it may be possible for a guest to trigger exceptions with classes that
we don't recognise.
While we can't service these exceptions in a manner useful to the guest,
we can avoid bringing down the host. Per ARM DDI 0487A.k_iss10775, page
D7-1937, EC values within the range 0x00 - 0x2c are reserved for future
use with synchronous exceptions, and EC values within the range 0x2d -
0x3f may be used for either synchronous or asynchronous exceptions.
The patch makes KVM handle any unknown EC by injecting an UNDEFINED
exception into the guest, with a corresponding (ratelimited) warning in
the host dmesg. We could later improve on this with with a new (opt-in)
exit to the host userspace.

Currently, if a vcpu thread tries to change the active state of an
interrupt which is already on the same vcpu's AP list, it will loop
forever. Since the VGIC mmio handler is called after a vcpu has
already synced back the LR state to the struct vgic_irq, we can just
let it proceed safely.

On Qualcomm Datacenter Technologies QDF2400 SoCs, the ITS hardware
implementation uses 16Bytes for Interrupt Translation Entry (ITE),
but reports an incorrect value of 8Bytes in GITS_TYPER.ITTE_size.
It might cause kernel memory corruption depending on the number
of MSI(x) that are configured and the amount of memory that has
been allocated for ITEs in its_create_device().
This patch fixes the potential memory corruption by setting the
correct ITE size to 16Bytes.

osd_request_timeout is osdkeepalive-precise -- in-flight requests are

Arnd Bergmann reported a (false positive) objtool warning:
drivers/infiniband/sw/rxe/rxe_resp.o: warning: objtool: rxe_responder()+0xfe: sibling call from callable instruction with changed frame pointer
The issue is in find_switch_table(). It tries to find a switch
statement's jump table by walking backwards from an indirect jump
instruction, looking for a relocation to the .rodata section. In this
case it stopped walking prematurely: the first .rodata relocation it
encountered was for a variable (resp_state_name) instead of a jump
table, so it just assumed there wasn't a jump table.
The fix is to ignore any .rodata relocation which refers to an ELF
object symbol. This works because the jump tables are anonymous and
have no symbols associated with them.

Current Audio-DMAC is assigned "rx" as Audio-DMAC0, "tx" as Audio-DMAC1.
Thus, DVC "tx" should be assigned as Audio-DMAC1, instead of Audio-DMAC0.
Because of this, current platform board (using SRC/DVC/SSI)
Playback/Capture both will use same Audio-DMAC0
(but it depends on data path).
First note is that this "rx" and "tx" are from each IP point,
it doesn't mean Playback/Capture.
Second note is that Audio DMAC assigned on DT is only for
Audio-DMAC, Audio-DMAC-peri-peri has no entry.
=> Audio-DMAC
-> Audio-DMAC-peri-peri
-- HW connection
Playback case
[Mem] => [SRC]--[DVC] -> [SSI]--[Codec]
rx ~~~~~~~~~~~~
Capture
[Mem] <= [DVC]--[SRC] <- [SSI]--[Codec]
tx ~~~~~~~~~~~~

The Cortex-A7 cache controller is an integrated controller, and thus the
device node representing it should not have a unit-addresses or reg
property.
