Hi Kirill,
FYI this bug is still active in tip/master:

x86/boot/64: Rewrite startup_64() in C
The patch write most of startup_64 logic in C.
This is preparation for 5-level paging enabling.

18b9c996c7 ("vsprintf: Add %p extension "%pOF" for device tree"): BUG: KASAN: stack-out-of-bounds in string
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit 18b9c996c725246801d0a631698a62c7acee98ca
Author: Pantelis Antoniou <pantelis.antoniou(a)konsulko.com>
AuthorDate: Wed Jan 21 19:06:14 2015 +0200
Commit: Rob Herring <robh(a)kernel.org>
CommitDate: Mon Jun 26 09:53:23 2017 -0500
vsprintf: Add %p extension "%pOF" for device tree
90% of the usage of device node's full_name is printing it out in a
kernel message. However, storing the full path for every node is
wasteful and redundant. With a custom format specifier, we can generate
the full path at run-time and eventually remove the full path from every
node.
For instance typical use is:
pr_info("Frobbing node %s\n", node->full_name);
Which can be written now as:
pr_info("Frobbing node %pOF\n", node);
'%pO' is the base specifier to represent kobjects with '%pOF'
representing struct device_node. Currently, struct device_node is the
only supported type of kobject.
More fine-grained control of formatting includes printing the name,
flags, path-spec name and others, explained in the documentation entry.
Originally written by Pantelis, but pretty much rewrote the core
function using existing string/number functions. The 2 passes were
unnecessary and have been removed. Also, updated the checkpatch.pl
check. The unittest code was written by Grant Likely.

[rtmutex] cde50a6739 swapper/1 is trying to release lock (rcu_preempt_state) at:
by Fengguang Wu
Greetings,
FYI, here is another unlock balance problem.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit cde50a67397c0da7d11795d4b4418384022ab8e6
Author: Levin, Alexander (Sasha Levin) <alexander.levin(a)verizon.com>
AuthorDate: Sun Jun 18 14:06:01 2017 +0000
Commit: Ingo Molnar <mingo(a)kernel.org>
CommitDate: Tue Jun 20 11:53:09 2017 +0200
locking/rtmutex: Don't initialize lockdep when not required
pi_mutex isn't supposed to be tracked by lockdep, but just
passing NULLs for name and key will cause lockdep to spew a
warning and die, which is not what we want it to do.
Skip lockdep initialization if the caller passed NULLs for
name and key, suggesting such initialization isn't desired.

Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes and updates from Jens Axboe:
"Some fixes and followup features/changes that should go in, in this
merge window. This contains:
- Two fixes for lightnvm from Javier, fixing problems in the new code
merge previously in this merge window.
- A fix from Jan for the backing device changes, fixing an issue in
NFS that causes a failure to mount on certain setups.
- A change from Christoph, cleaning up the blk-mq init and exit
request paths.
- Remove elevator_change(), which is now unused. From Bart.
- A fix for queue operation invocation on a dead queue, from Bart.
- A series fixing up mtip32xx for blk-mq scheduling, removing a
bandaid we previously had in place for this. From me.
- A regression fix for this series, fixing a case where we wait on
workqueue flushing from an invalid (non-blocking) context. From me.
- A fix/optimization from Ming, ensuring that we don't both quiesce
and freeze a queue at the same time.
- A fix from Peter on lock ordering for CPU hotplug. Not a real
problem right now, but will be once the CPU hotplug rework goes in.
- A series from Omar, cleaning up out blk-mq debugfs support, and
adding support for exporting info from schedulers in debugfs as
well. This is really useful in debugging stalls or livelocks. From
Omar"

[rtmutex] cde50a6739 udevd/1243 is trying to release lock (rcu_preempt_state) at:
by Fengguang Wu
Greetings,
FYI it may not be a new problem, however looks relevant to rtmutex.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit cde50a67397c0da7d11795d4b4418384022ab8e6
Author: Levin, Alexander (Sasha Levin) <alexander.levin(a)verizon.com>
AuthorDate: Sun Jun 18 14:06:01 2017 +0000
Commit: Ingo Molnar <mingo(a)kernel.org>
CommitDate: Tue Jun 20 11:53:09 2017 +0200
locking/rtmutex: Don't initialize lockdep when not required
pi_mutex isn't supposed to be tracked by lockdep, but just
passing NULLs for name and key will cause lockdep to spew a
warning and die, which is not what we want it to do.
Skip lockdep initialization if the caller passed NULLs for
name and key, suggesting such initialization isn't desired.

KVM: async_pf: Let host know whether the guest support delivery async_pf as #PF vmexit
Adds another flag bit (bit 2) to MSR_KVM_ASYNC_PF_EN. If bit 2 is 1, async
page faults are delivered to L1 as #PF vmexits; if bit 2 is 0, kvm_can_do_async_pf
returns 0 if in guest mode.

040de6ebde ("mtd: Fallback to ->_read/write_oob() when ->_read/wr..."): BUG: unable to handle kernel NULL pointer dereference at (null)

Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

mtd: Fallback to ->_read/write_oob() when ->_read/write() is missing
Some MTD sublayers/drivers are implementing ->_read/write_oob() and
providing dummy wrappers for their ->_read/write() implementations.
Let the core handle this case instead of duplicating the logic.
