Switch the driver to atomic PWM. This makes it easier to wait a proper
amount of time when changing the duty cycle before disabling the channel
(main use case is switching the duty cycle to 0 before disabling).

When our RDMA queue-pair is torn down with high load
of I/O traffic, we have no way of knowing if the
memory region was actually registered by the reg_mr
work request as it completion flushes with error (hw
might have done it or not).
So in order to not deal with all this uncertanty, we
simply recycle the MR in reinit_request.

Usually before we teardown the controller we want to:
1. complete/cancel any ctrl inflight works
2. remove ctrl namespaces (only for removal though, resets
shouldn't remove any namespaces).
but we do not want to destroy the controller device as
we might use it for logging during the teardown stage.
This patch adds nvme_start_ctrl() which queues inflight
controller works (aen, ns scan, queue start and keep-alive
if kato is set) and nvme_stop_ctrl() which cancels the works
namespace removal is left to the callers to handle.
Move nvme_uninit_ctrl after we are done with the
controller device.

Unlike blk_mq_stop_hw_queues, blk_mq_quiesce_queue respects the
submission path rcu grace. quiesce the queue before iterating
on live tags, or performing device io quiescing.
While were at it, verify that the request started in mtip_abort_cmd

the queues
When we requeue a request, we can always insert the request
back to the scheduler instead of doing it when restarting
the queues and kicking the requeue work, so get rid of
the requeue kick in nvme (core and drivers).
Also, now there is no need start hw queues in nvme_kill_queues
We don't stop the hw queues anymore, so no need to
start them.

This patch improves the way the RDMA IB signalling is done by using atomic
operations for the signalling variable. This avoids race conditions on
sig_count.
The signalling interval changes slightly and is now the largest power of
two not larger than queue depth / 2.

Every developer always thinks that _their_ code is so special and
magical that it should be enabled by default.
And most of them are completely and utterly wrong. That's definitely
the case when you write a specialty driver for a very unsual "security
processor". It does *not* get to mark itself as "default m".
If you solve world hunger, and make a driver that cures people of
cancer, by all means enable it by default. But afaik, the Cavium
CNN55XX does neither.

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security layer updates from James Morris:
- a major update for AppArmor. From JJ:
* several bug fixes and cleanups
* the patch to add symlink support to securityfs that was floated
on the list earlier and the apparmorfs changes that make use of
securityfs symlinks
* it introduces the domain labeling base code that Ubuntu has been
carrying for several years, with several cleanups applied. And it
converts the current mediation over to using the domain labeling
base, which brings domain stacking support with it. This finally
will bring the base upstream code in line with Ubuntu and provide
a base to upstream the new feature work that Ubuntu carries.
* This does _not_ contain any of the newer apparmor mediation
features/controls (mount, signals, network, keys, ...) that
Ubuntu is currently carrying, all of which will be RFC'd on top
of this.
- Notable also is the Infiniband work in SELinux, and the new file:map
permission. From Paul:
"While we're down to 21 patches for v4.13 (it was 31 for v4.12),
the diffstat jumps up tremendously with over 2k of line changes.
Almost all of these changes are the SELinux/IB work done by
Daniel Jurgens; some other noteworthy changes include a NFS v4.2
labeling fix, a new file:map permission, and reporting of policy
capabilities on policy load"
There's also now genfscon labeling support for tracefs, which was
lost in v4.1 with the separation from debugfs.
- Smack incorporates a safer socket check in file_receive, and adds a
cap_capable call in privilege check.
- TPM as usual has a bunch of fixes and enhancements.
- Multiple calls to security_add_hooks() can now be made for the same
LSM, to allow LSMs to have hook declarations across multiple files.
- IMA now supports different "ima_appraise=" modes (eg. log, fix) from
the boot command line.

This adds a debugfs consumer for the exported kernel API
intel_pmc_read_s0ix_residency. This debugfs entry reads S0ix residency
directly from the PMC hardware counters.
TEST:
- echo freeze > /sys/power/state
- Wake the system, read the S0ix residency i.e.
cat /sys/kernel/debug/telemetry/s0ix_residency_usec

This fixes an oops found while testing load/unload of the
intel_telemetry_debugfs module. module_init uses register_pm_notifier
for PM callbacks, but unregister_pm_notifier was missing from
module_exit.

It is observed reading the register from HW takes a bit long,
for example in my box, the following difference of 'perf report
--no-children fio ...' can be seen when running I/O:
1) V4.12 without patch
+ 9.28% fio [mtip32xx] [k] mtip_irq_handler
+ 8.48% fio [mtip32xx] [k] mtip_init_cmd_header
2) V4.12 with the following patch
+ 9.14% fio [mtip32xx] [k] mtip_irq_handler
......
+ 1.14% fio [mtip32xx] [k] mtip_init_cmd_header
IOPS can be increased by ~5% with this patch too.
Fixes: a4e84aae8139(mtip32xx: use runtime tag to initialize command header)

The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).
There are some boards which have the pin strapped this way and need
software workaround suggested by the data manual. Bit[7] of
Configuration Register 4 (address 0x0031) must be cleared to 0. This
ensures proper operation of the PHY.
Implement driver support for device-tree property meant to advertise
the wrong strapping.
