Pull wchan kernel address hiding from Ingo Molnar:
"This fixes a wchan related information leak in /proc/PID/stat.
There's a bit of an ABI twist to it: instead of setting the wchan
field to 0 (which is our usual technique) we set it conditionally to a
0/1 flag to keep ABI compatibility with older procps versions that
only fetches /proc/PID/wchan (symbolic names) if the absolute wchan
address is nonzero"
* 'core-debug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
fs/proc, core/debug: Don't expose absolute kernel addresses via wchan
"nlb_pr_rq" can't be more than u32 because "len" is a u32. Later we
truncate it to u32 anyway when we calculate min_t().

Pull ARM updates from Russell King:
"In this ARM merge, we remove more lines than we add. Changes include:
- Enable imprecise aborts early, so that bus errors aren't masked
until later in the boot. This has the side effect that boot
loaders which provoke these aborts can cause the kernel to crash
early in boot, so we install a handler to report this event around
the site where these are enabled.
- Remove the buggy but impossible to enable cmpxchg syscall code.
- Add unwinding annotations to some assembly code.
- Add support for atomic half-word exchange for ARMv6k+.
- Reduce ioremap() alignment for SMP/LPAE cases where we don't need
the large alignment.
- Addition of an "optimal" 3G configuration for systems with 1G of
RAM.
- Increase vmalloc space by 128M.
- Constify some SMP operations structures, which have never been
writable.
- Improve ARMs dma_mmap() support for mapping DMA coherent mappings
into userspace.
- Fix to the NMI backtrace code in the IPI case on ARM where the
failing CPU gets stuck for 10s waiting for its own IPI to be
delivered.

DSA ports must be members of a VLAN in order to ensure frame bridging
between chained switch chips.
Thus tag them in addition to the CPU port when adding a VLAN, and skip
them when deleting a VLAN and reporting VLAN members.
Also use the UNMODIFIED egress policy, so that frames egress on these
ports as they ingress, tagged or untagged.

The newly added led trigger support in the com20020-pci driver causes
build errors when CONFIG_LEDS_CLASS is disabled:
drivers/built-in.o: In function `com20020pci_probe':
(.text+0x185dc4): undefined reference to `devm_led_classdev_register'
(.text+0x185dd8): undefined reference to `devm_led_classdev_register'
This adds a Kconfig dependency to prevent the invalid configurations.
Other drivers appear to be split 50:50 between 'select' and 'depends on'
for this symbol, I picked 'depends on' as I could not find a common
policy and it generally causes fewer problems.

Currently rx_timestamp_work reschedules itself as a regular workqueue item,

Only using the message type and sequence id for matching timestamps
with packets is error prone, as multiple clients may very well be
sending packets with the same messagetype and timestamp at the same
time. Fix by extending the check to include the hash of bytes 20-29
(source id in PTPv2) that is provided with the timestamps.

Both tunnel6_protocol and tunnel46_protocol share the same error
handler, tunnel6_err(), which traverses through tunnel6_handlers list.
For ipip6 tunnels, we need to traverse tunnel46_handlers as we do e.g.
in tunnel46_rcv(). Current code can generate an ICMPv6 error message
with an IPv4 packet embedded in it.

Hi,
Zhangqing Luo reported long boot times on a system with thousands of
LUNs when scsi-mq was enabled. He narrowed the problem down to
blk_mq_add_queue_tag_set, where every queue is frozen in order to set
the BLK_MQ_F_TAG_SHARED flag. Each added device will freeze all queues
added before it in sequence, which involves waiting for an RCU grace
period for each one. We don't need to do this. After the second queue
is added, only new queues need to be initialized with the shared tag.
We can do that by percolating the flag up to the blk_mq_tag_set, and
updating the newly added queue's hctxs if the flag is set.
This problem was introduced by commit 0d2602ca30 (blk-mq: improve
support for shared tags maps).

these resources will remain closed.
So when executing (following) configuration operations (e.g ifconfig

Depending on the gcc version we can use builtin_bswap instead of
architecture functions. Doing so is better than the inline assembly
version of load reverse for two reasons:
- the sequence of load reversed, apply constant mask, save reversed can
be optimized to load, apply reversed mask, save
- builtins are slightly better to optimize e.g. gcc instruction
scheduler cannot optimize grouping on inline assemblies.
To enable set we have to ARCH_USE_BUILTIN_BSWAP.

Path verification is either done via dasd_eckd_read_conf() which is
triggered during online processing and resume or via
do_path_verification_work() which is triggered after path events.
The dasd_eckd_read_conf() version added paths unconditionally and did
not check if the path mask was empty. This led to devices having the
disconnected stop flag set but a valid path mask. So they where not
working although they had paths validated successfully. After a resume
this state could even not be solved with additional paths added.
Fix by checking for an empty path mask in dasd_eckd_read_conf() and
clearing the device stop bits for a newly added channel path.
