While running reboot tests w/ a specific set of USB devices (and
slub_debug enabled), I found that once every few hours my device would
be crashed with a stack that looked like this:

Investigation using kgdb() found that the wait queue that was passed
into wake_up() had been freed (it was filled with slub_debug poison).
I analyzed and instrumented the code and reproduced. My current
belief is that this is happening:
1. async_completed() is called (from IRQ). Moves "as" onto the
completed list.
2. On another CPU, proc_reapurbnonblock_compat() calls
async_getcompleted(). Blocks on spinlock.
3. async_completed() releases the lock; keeps running; gets blocked
midway through wake_up().
4. proc_reapurbnonblock_compat() => async_getcompleted() gets the
lock; removes "as" from completed list and frees it.
5. usbdev_release() is called. Frees "ps".
6. async_completed() finally continues running wake_up(). ...but
wake_up() has a pointer to the freed "ps".
The instrumentation that led me to believe this was based on adding
some trace_printk() calls in a select few functions and then using
kdb's "ftdump" at crash time. The trace follows (NOTE: in the trace
below I cheated a little bit and added a udelay(1000) in
async_completed() after releasing the spinlock because I wanted it to
trigger quicker):
<...>-2104 0d.h2 13759034us!: async_completed at start: as=ffffffc0cc638200
mtpd-2055 3.... 13759356us : async_getcompleted before spin_lock_irqsave
mtpd-2055 3d..1 13759362us : async_getcompleted after list_del_init: as=ffffffc0cc638200
mtpd-2055 3.... 13759371us+: proc_reapurbnonblock_compat: free_async(ffffffc0cc638200)
mtpd-2055 3.... 13759422us+: async_getcompleted before spin_lock_irqsave
mtpd-2055 3.... 13759479us : usbdev_release at start: ps=ffffffc0cc042080
mtpd-2055 3.... 13759487us : async_getcompleted before spin_lock_irqsave
mtpd-2055 3.... 13759497us!: usbdev_release after kfree(ps): ps=ffffffc0cc042080
<...>-2104 0d.h2 13760294us : async_completed before wake_up(): as=ffffffc0cc638200
To fix this problem we can just move the wake_up() under the ps->lock.
There should be no issues there that I'm aware of.

The musb_dsps driver is special in that the parent (glue) device's
driver is accessing registers mapped by the child. The clock is however
shared and is managed by the grandparent device.
Since commit 869c59782981 ("usb: musb: dsps: add support for suspend and
resume") the dsps driver has been accessing these registers as part of
suspend and resume.
The parent driver obviously cannot runtime resume the child during
system suspend and is currently relying on the fact that the child will
be RPM_ACTIVE throughout suspend. The suspend implementation also makes
sure to check that the child is indeed present (and hence the clock
enabled) before accessing the registers.
Let's add an explicit runtime resume of the glue device itself to enable
the clock before doing the register accesses in case these assumptions ever
change (i.e. if the child is left runtime suspended).
Note that the glue-timer cancellation is moved after the child-presence
check to keep error handling simple. This should be fine as the timer is
not setup until the controller is being registered and at that time
glue->musb and its driver data have already been initialised.

Make sure that the controller is runtime resumed when system suspending
to avoid an external abort when accessing the interrupt registers:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xd025840a
...
[<c05481a4>] (musb_default_readb) from [<c0545abc>] (musb_disable_interrupts+0x84/0xa8)
[<c0545abc>] (musb_disable_interrupts) from [<c0546b08>] (musb_suspend+0x38/0xb8)
[<c0546b08>] (musb_suspend) from [<c04a57f8>] (platform_pm_suspend+0x3c/0x64)
This is easily reproduced on a BBB by enabling the peripheral port only
(as the host port may enable the shared clock) and keeping it
disconnected so that the controller is runtime suspended. (Well, you
would also need to the not-yet-merged am33xx-suspend patches by Dave
Gerlach to be able to suspend the BBB.)
This is a regression that was introduced by commit 1c4d0b4e1806 ("usb:
musb: Remove pm_runtime_set_irq_safe") which allowed the parent glue
device to runtime suspend and thereby exposed a couple of older issues:
Register accesses without explicitly making sure the controller is
runtime resumed during suspend was first introduced by commit c338412b5ded
("usb: musb: unconditionally save and restore the context on suspend")
in 3.14.
Commit a1fc1920aaaa ("usb: musb: core: make sure musb is in RPM_ACTIVE on
resume") later started setting the RPM status to active during resume,
and this was also implicitly relying on the parent always being active.
Since commit 71723f95463d ("PM / runtime: print error when activating a
child to unactive parent") this now also results in the following
warning:
musb-hdrc musb-hdrc.0: runtime PM trying to activate child device
musb-hdrc.0 but parent (47401400.usb) is not active
This patch has been verified on 4.13-rc2, 4.12 and 4.9 using a BBB
(the dsps glue would always be active also in 4.8).

The changes in this commit are also being sent to the main rtlwifi
drivers in wireless-next; however, these changes will also be useful for
any debugging of r8822be before it gets moved into the main tree.
Use debugfs to dump register and btcoex status, and also write registers
and h2c.
We create topdir in /sys/kernel/debug/rtlwifi/, and use the MAC address
as subdirectory with several entries to dump mac_reg, bb_reg, rf_reg etc.
An example is
/sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/mac_0
This change permits examination of device registers in a dynamic manner,
a feature not available with the current debug mechanism.
We use seq_file to replace RT_TRACE to dump status, then we can use 'cat'
to access btcoex's status through debugfs.
(i.e. /sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/btcoex)
Other related changes are
1. implement btc_disp_dbg_msg() to access btcoex's common status.
2. remove obsolete field bt_exist

Smatch is distrustful of the "capab" value and marks it as user

"Another fix, this time in common IOMMU sysfs code.
In the conversion from the old iommu sysfs-code to the

device', which was a pointer before, but is now embedded in another

Freeing from the middle of allocated memory had all kinds of nasty
side effects when an IOMMU was unplugged. Unfortunatly nobody
unplugged and IOMMU until now, so this was not discovered earlier. The
fix is to make the 'struct device' a pointer again"

rtl8169_tx_clear_range() is responsible for cleaning up the TX ring
during interface shutdown, incrementing tx_dropped for every SKB that we
left at the time in the ring is misleading.

Pull MTD fixes from Brian Norris:
"Two fixes - one for a 4.13 regression, and the other for an older one:
- Atmel NAND: since we started utilizing ONFI timings, we found that
we were being too restrict at rejecting them, partly due to
discrepancies in ONFI 4.0 and earlier versions. Relax the
restriction to keep these platforms booting. This is a 4.13-rc1
regression.
- nandsim: repeated probe/removal may not work after a failed init,
because we didn't free up our debugfs files properly on the failure
path. This has been around since 3.8, but it's nice to get this
fixed now in a nice easy patch that can target -stable, since
there's already refactoring work (that also fixes the issue)
targeted for the next merge window"

Pull block fixes from Jens Axboe:
"A small batch of fixes that should be included for the 4.13 release.
This contains:
- Revert of the 4k loop blocksize support. Even with a recent batch
of 4 fixes, we're still not really happy with it. Rather than be
stuck with an API issue, let's revert it and get it right for 4.14.
- Trivial patch from Bart, adding a few flags to the blk-mq debugfs
exports that were added in this release, but not to the debugfs
parts.
- Regression fix for bsg, fixing a potential kernel panic. From
Benjamin.
- Tweak for the blk throttling, improving how we account discards.
From Shaohua"

irq_create_affinity_masks() can return NULL on non-SMP systems, when there
are not enough "free" vectors available to spread, or if memory allocation
for the CPU masks fails. Only the allocation failure is of interest, and
even then the system will work just fine except for non-optimally spread
vectors. Thus remove the warnings.
