Deepa Dinamani 8bbd47140c ceph: replace CURRENT_TIME by current_fs_time()
CURRENT_TIME macro is not appropriate for filesystems as it
doesn't use the right granularity for filesystem timestamps.
Use current_fs_time() instead.

Yan, Zheng 5b64640cf6 ceph: scattered page writeback
This patch makes ceph_writepages_start() try using single OSD request
to write all dirty pages within a strip unit. When a nonconsecutive
dirty page is found, ceph_writepages_start() tries starting a new write
operation to existing OSD request. If it succeeds, it uses the new
operation to writeback the dirty page.

Ilya Dryomov 3f1af42ad0 libceph: enable large, variable-sized OSD requests
Turn r_ops into a flexible array member to enable large, consisting of
up to 16 ops, OSD requests.  The use case is scattered writeback in
cephfs and, as far as the kernel client is concerned, 16 is just a made
up number.

r_ops had size 3 for copyup+hint+write, but copyup is really a special
case - it can only happen once.  ceph_osd_request_cache is therefore
stuffed with num_ops=2 requests, anything bigger than that is allocated
with kmalloc().  req_mempool is backed by ceph_osd_request_cache, which
means either num_ops=1 or num_ops=2 for use_mempool=true - all existing
users (ceph_writepages_start(), ceph_osdc_writepages()) are fine with
that.

Ilya Dryomov b5d91704f5 libceph: behave in mon_fault() if cur_mon < 0
This can happen if __close_session() in ceph_monc_stop() races with
a connection reset.  We need to ignore such faults, otherwise it's
likely we would take !hunting, call __schedule_delayed() and end up
with delayed_work() executing on invalid memory, among other things.

The (two!) con->private tests are useless, as nothing ever clears
con->private.  Nuke them.

Ilya Dryomov bee3a37c47 libceph: reschedule tick in mon_fault()
Doing __schedule_delayed() in the hunting branch is pointless, as the
tick will have already been scheduled by then.

What we need to do instead is *reschedule* it in the !hunting branch,
after reopen_session() changes hunt_mult, which affects the delay.
This helps with spacing out connection attempts and avoiding things
like two back-to-back attempts followed by a longer period of waiting
around.

Ilya Dryomov 168b9090c7 libceph: monc hunt rate is 3s with backoff up to 30s
Unless we are in the process of setting up a client (i.e. connecting to
the monitor cluster for the first time), apply a backoff: every time we
want to reopen a session, increase our timeout by a multiple (currently
2); when we complete the connection, reduce that multipler by 50%.

Split ping interval and ping timeout: ping interval is 10s; keepalive
timeout is 30s.

Make monc_ping_timeout a constant while at it - it's not actually
exported as a mount option (and the rest of tick-related settings won't
be either), so it's got no place in ceph_options.

Ilya Dryomov 0e04dc26cc libceph: pick a different monitor when reconnecting
Don't try to reconnect to the same monitor when we fail to establish
a session within a timeout or it's lost.

For that, pick_new_mon() needs to see the old value of cur_mon, so
don't clear it in __close_session() - all calls to __close_session()
but one are followed by __open_session() anyway.  __open_session() is
only called when a new session needs to be established, so the "already
open?" branch, which is now in the way, is simply dropped.

Ilya Dryomov 82dcabad75 libceph: revamp subs code, switch to SUBSCRIBE2 protocol
It is currently hard-coded in the mon_client that mdsmap and monmap
subs are continuous, while osdmap sub is always "onetime".  To better
handle full clusters/pools in the osd_client, we need to be able to
issue continuous osdmap subs.  Revamp subs code to allow us to specify
for each sub whether it should be continuous or not.

Although not strictly required for the above, switch to SUBSCRIBE2
protocol while at it, eliminating the ambiguity between a request for
"every map since X" and a request for "just the latest" when we don't
have a map yet (i.e. have epoch 0).  SUBSCRIBE2 feature bit is now
required - it's been supported since pre-argonaut (2010).

Move "got mdsmap" call to the end of ceph_mdsc_handle_map() - calling
in before we validate the epoch and successfully install the new map
can mess up mon_client sub state.

Ilya Dryomov 02ac956c42 libceph: move debugfs initialization into __ceph_open_session()
Our debugfs dir name is a concatenation of cluster fsid and client
unique ID ("global_id").  It used to be the case that we learned
global_id first, nowadays we always learn fsid first - the monmap is
sent before any auth replies are.  ceph_debugfs_client_init() call in
ceph_monc_handle_map() is therefore never executed and can be removed.

Its counterpart in handle_auth_reply() doesn't really belong there
either: having to do monc->client and unlocking early to work around
lockdep is a testament to that.  Move it into __ceph_open_session(),
where it can be called unconditionally.

     driver, from Alexey Khoroshilov.

   - A set of fixes for lightnvm, from Javier, Matias, and Wenwei.

   - An NVMe completion record corruption fix from Marta, ensuring that
     we read things in the right order.

   - Two writeback fixes from Tejun, marked for stable@ as well.

   - A blk-mq sw queue iterator fix from Thomas, fixing an oops for
     sparse CPU maps.  They hit this in the hot plug/unplug rework"

   on the clk tree, so I delayed that a bit. Support for the new
   i.MX6qp SoC and a couple of new boards is added in this branch.
 
 * Uniphier renames a few files to match the final product names
   that were decided by the company, kudos to the kernel developer(s)
   for getting support upstream before the product release.
   Also two boards are added. The patches were posted early enough
   and nice overall, but we forgot to apply them and decided to
   give it some more time in linux-next
 
 * at91 has two small bug fixes.

Mylène Josserand ee08774424 rtc: abx80x: handle the oscillator failure bit
Handle the Oscillator Failure ('OF') bit from Oscillator Status register
(0x1D). This bit is cleared on set_time function and is read each time the
date/time is read, but only in case of XT Oscillator selection.
In RC mode, this bit is always set.

Mylène Josserand 59a8383adb rtc: abx80x: handle autocalibration
The autocalibration is separated in two bits to set in Oscillator
Control register (0x1c) :
 - OSEL bit to select the oscillator type (XT or RC).
 - ACAL bit to select the autocalibration type.

These functionnalities are exported in sysfs entries : "oscillator"
and "autocalibration". Respectively, the values are "xtal" for XT
oscillator and "rc" for RC oscillator and 0 to disable the
autocalibration cycle, 512 for a 512 seconds autocalibration cycle
and 1024 for a cycle of 1024 seconds.

Examples :
Set to XT Oscillator
echo xtal > /sys/class/rtc/rtc0/device/oscillator
Activate an autocalibration every 512 seconds
echo 512 > /sys/class/rtc/rtc0/device/autocalibration

Alexandre Belloni 85062c9b99 rtc: rv8803: workaround i2c HW issue
The rv8803 has a 60µs window where it will not answer on the i2c bus.
It also means there will be no ack for the communication. Make sure
communication is tried multiple times when this happens (the i2c subsystem
mandates -ENXIO is that case but the number of retries is host specific).
The critical parts are the probe function and the alarm callback so make
sure we handle the failure there.

Linus Torvalds e46b4e2b46 Nothing major this round. Mostly small clean ups and fixes.
Some visible changes:
 
  A new flag was added to distinguish traces done in NMI context.
 
  Preempt tracer now shows functions where preemption is disabled but
  interrupts are still enabled.
 
 Other notes:
 
  Updates were done to function tracing to allow better performance
  with perf.
 
  Infrastructure code has been added to allow for a new histogram
  feature for recording live trace event histograms that can be
  configured by simple user commands. The feature itself was just
  finished, but needs a round in linux-next before being pulled.
  This only includes some infrastructure changes that will be needed.

Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276b5 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276b5, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276b5 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

   Fix things to ignore such bogus trip points.  (Zhang Rui)

 - Introduce Mediatek thermal driver.  (Sascha Hauer)

 - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
   Dewangan)

 - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof
   Kozlowski)

 - Introduce Skylake support in intel_pch_thermal driver.  (Srinivas
