#1707614 — [PATCH 4.12 002/106] parisc: Handle vmas whose context is not current in flush_cache_range

4.12-stable review patch.  If anyone has any objections, please let me know.

From: John David Anglin <dave.anglin@bell.net>

commit 13d57093c141db2036364d6be35e394fc5b64728 upstream.

In testing James' patch to drivers/parisc/pdc_stable.c, I hit the BUG
statement in flush_cache_range() during a system shutdown:

This patch modifies flush_cache_range() to handle non current contexts.
In as much as this occurs infrequently, the simplest approach is to
flush the entire cache when this happens.

#1707618 — [PATCH 4.12 009/106] libata: array underflow in ata_find_dev()

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 59a5e266c3f5c1567508888dd61a45b86daed0fa upstream.

My static checker complains that "devno" can be negative, meaning that
we read before the start of the loop.  I've looked at the code, and I
think the warning is right.  This come from /proc so it's root only or
it would be quite a quite a serious bug.  The call tree looks like this:

proc_scsi_write() <- gets id and channel from simple_strtoul()
-> scsi_add_single_device() <- calls shost->transportt->user_scan()
   -> ata_scsi_user_scan()
      -> ata_find_dev()

#1707619 — [PATCH 4.12 010/106] workqueue: restore WQ_UNBOUND/max_active==1 to be ordered

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tejun Heo <tj@kernel.org>

commit 5c0338c68706be53b3dc472e4308961c36e4ece1 upstream.

The combination of WQ_UNBOUND and max_active == 1 used to imply
ordered execution.  After NUMA affinity 4c16bd327c74 ("workqueue:
implement NUMA affinity for unbound workqueues"), this is no longer
true due to per-node worker pools.

While the right way to create an ordered workqueue is
alloc_ordered_workqueue(), the documentation has been misleading for a
long time and people do use WQ_UNBOUND and max_active == 1 for ordered
workqueues which can lead to subtle bugs which are very difficult to
trigger.

It's unlikely that we'd see noticeable performance impact by enforcing
ordering on WQ_UNBOUND / max_active == 1 workqueues.  Let's
automatically set __WQ_ORDERED for those workqueues.

#1707620 — [PATCH 4.12 005/106] ACPI / LPSS: Only call pwm_add_table() for the first PWM controller

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@redhat.com>

commit dd242a080d178c36442a0bb28b6acf6f126d0569 upstream.

At least on the UP board SBC both PWMs are enabled leading to us
trying to add the same pwm_lookup twice, which leads to the following:

[    0.902224] list_add double add: new=ffffffffb8efd400,
               prev=ffffffffb8efd400, next=ffffffffb8eeede0.

This commit fixes this by only calling pwm_add_table() for the first
PWM controller (which is the one used for the backlight).

I didn't look too closely because looks like there was another patch
added, and this time through, only 8 failures[1] (out of 524 boots).
I'll try to have a closer look at those today, but a first glance looks
like there aren't any real regressions.
