Use a saner size calculation, and do a trivial cleanup on the zone
revalidation to prepare to future changes.

For zoned=1 mode, the zone size must be a power of 2. Check this not
only when the zone size is specified during modprobe, but also when
creating a zoned null_blk device using configfs.

bvec_iter_advance() is quite popular, but compilers fail to do proper
alias analysis and optimise it good enough. The assembly is checked
for gcc 9.2, x86-64.
- remove @iter->bi_size from min(...), as it's always less than @bytes.
Modify at the beginning and forget about it.
- the compiler isn't able to collapse memory dependencies and remove
writes in the loop. Help it by explicitely using local vars.

If this flag is set, applications can be certain that any data for

Add a utility function dmi_memdev_handle() which returns the DMI
handle associated with a given memory slot. This will allow kernel
drivers to iterate over the memory slots.

Currently we don't copy the iovecs when we punt to async context. This
can be problematic for applications that store the iovec on the stack,
as they often assume that it's safe to let the iovec go out of scope
as soon as IO submission has been called. This isn't always safe, as we
will re-copy the iovec once we're in async context.
Make this 100% safe by copying the iovec just once. With this change,
applications may safely store the iovec on the stack for all cases.

Right now we just copy the sqe for async offload, but we want to store
more context across an async punt. In preparation for doing so, put the
sqe copy inside a structure that we can expand. With this pointer added,
we can get rid of REQ_F_FREE_SQE, as that is now indicated by whether
req->io is NULL or not.
No functional changes in this patch.

Commit 6917d0689993 ("block: merge invalidate_partitions into
rescan_partitions") caused a regression where systemd-udevd spins
forever using max CPU starting at boot time.
It's caused by a behavior change where a KOBJ_CHANGE uevent is now sent
in a case where previously it wasn't.
Restore the old behavior.

Pull XFS updates from Darrick Wong:
"For this release, we changed quite a few things.
Highlights:
- Fixed some long tail latency problems in the block allocator
- Removed some long deprecated (and for the past several years no-op)
mount options and ioctls
- Strengthened the extended attribute and directory verifiers
- Audited and fixed all the places where we could return EFSCORRUPTED
without logging anything

billion(!) extents
- Fixed a longstanding bug where quota accounting could be incorrect
when performing unwritten extent conversion on a freshly mounted fs
- Fixed various complaints in scrub about soft lockups and
unresponsiveness to signals
- De-vtable'd the directory handling code, which should make it
faster
- Converted to the new mount api, for better or for worse
- Cleaned up some memory leaks
and quite a lot of other smaller fixes and cleanups.
A more detailed summary:
- Fill out the build string
- Prevent inode fork extent count overflows
- Refactor the allocator to reduce long tail latency

corrupting the file length
- Clean up various loose ends in the iomap and bmap code

We have been trying to use rasdaemon to monitor hardware errors like
correctable memory errors. rasdaemon uses trace events to monitor
various hardware errors. In order to test it, we have to inject some
hardware errors, unfortunately not all of them provide error
injections. MCE does provide a way to inject MCE errors, but errors
like PCI error and devlink error don't, it is not easy to add error
injection to each of them. Instead, it is relatively easier to just
allow users to inject trace events in a generic way so that all trace
events can be injected.
This patch introduces trace event injection, where a new 'inject' is
added to each tracepoint directory. Users could write into this file
with key=value pairs to specify the value of each fields of the trace
event, all unspecified fields are set to zero values by default.
For example, for the net/net_dev_queue tracepoint, we can inject:
INJECT=/sys/kernel/debug/tracing/events/net/net_dev_queue/inject
echo "" > $INJECT
echo "name='test'" > $INJECT
echo "name='test' len=1024" > $INJECT
cat /sys/kernel/debug/tracing/trace
...

<...>-614 [001] .N.. 208.431878: net_dev_queue: dev=test skbaddr=00000000fbf338c2 len=1024
Triggers could be triggered as usual too:
echo "stacktrace if len == 1025" > /sys/kernel/debug/tracing/events/net/net_dev_queue/trigger
echo "len=1025" > $INJECT
cat /sys/kernel/debug/tracing/trace

which is caused by slab fault injection triggering a failure in
prepare_creds(). We don't actually need to create a copy of the creds
as we're not modifying it, we just need a reference on the current task
creds. This avoids the failure case as well, and propagates the const
throughout the stack.

Note that the EC GPE processing need not be synchronized in
acpi_s2idle_wake() after invoking acpi_ec_dispatch_gpe(), because
that function checks the GPE status and dispatches its handler if
need be and the SCI action handler is not going to run anyway at
that point.
Moreover, it is better to drain all of the pending ACPI events
before restoring the working-state configuration of GPEs in
acpi_s2idle_restore(), because those events are likely to be related
to system wakeup, in which case they will not be relevant going
forward.
Rework the code to take these observations into account.

There is a race condition in the ACPI EC driver, between
__acpi_ec_flush_event() and acpi_ec_event_handler(), that may
cause systems to stay in suspended-to-idle forever after a wakeup
event coming from the EC.
Namely, acpi_s2idle_wake() calls acpi_ec_flush_work() to wait until
the delayed work resulting from the handling of the EC GPE in
acpi_ec_dispatch_gpe() is processed, and that function invokes
__acpi_ec_flush_event() which uses wait_event() to wait for
ec->nr_pending_queries to become zero on ec->wait, and that wait
queue may be woken up too early.
Suppose that acpi_ec_dispatch_gpe() has caused acpi_ec_gpe_handler()
to run, so advance_transaction() has been called and it has invoked
acpi_ec_submit_query() to queue up an event work item, so
ec->nr_pending_queries has been incremented (under ec->lock). The
work function of that work item, acpi_ec_event_handler() runs later
and calls acpi_ec_query() to process the event. That function calls
acpi_ec_transaction() which invokes acpi_ec_transaction_unlocked()
and the latter wakes up ec->wait under ec->lock, but it drops that
lock before returning.
When acpi_ec_query() returns, acpi_ec_event_handler() acquires
ec->lock and decrements ec->nr_pending_queries, but at that point
__acpi_ec_flush_event() (woken up previously) may already have
acquired ec->lock, checked the value of ec->nr_pending_queries (and
it would not have been zero then) and decided to go back to sleep.
Next, if ec->nr_pending_queries is equal to zero now, the loop
in acpi_ec_event_handler() terminates, ec->lock is released and
acpi_ec_check_event() is called, but it does nothing unless
ec_event_clearing is equal to ACPI_EC_EVT_TIMING_EVENT (which is
not the case by default). In the end, if no more event work items
have been queued up while executing acpi_ec_transaction_unlocked(),
there is nothing to wake up __acpi_ec_flush_event() again and it
sleeps forever, so the suspend-to-idle loop cannot make progress and
the system is permanently suspended.
To avoid this issue, notice that it actually is not necessary to
wait for ec->nr_pending_queries to become zero in every case in
which __acpi_ec_flush_event() is used.
First, during platform-based system suspend (not suspend-to-idle),
__acpi_ec_flush_event() is called by acpi_ec_disable_event() after
clearing the EC_FLAGS_QUERY_ENABLED flag, which prevents
acpi_ec_submit_query() from submitting any new event work items,
so calling flush_scheduled_work() and flushing ec_query_wq
subsequently (in order to wait until all of the queries in that
queue have been processed) would be sufficient to flush all of
the pending EC work in that case.
Second, the purpose of the flushing of pending EC work while
suspended-to-idle described above really is to wait until the
first event work item coming from acpi_ec_dispatch_gpe() is
complete, because it should produce system wakeup events if
that is a valid EC-based system wakeup, so calling
flush_scheduled_work() followed by flushing ec_query_wq is also
sufficient for that purpose.
Rework the code to follow the above observations.

and digital filters with at91 being the first user, a core addition to
replace the NULL returning i2c_new_probed_device() with an ERR_PTR
variant, and the pxa driver has finally being moved to use the generic
I2C slave interface. We have quite a significant number of reviews per
patch this time, so thank you to all involved!"

Pull block fixes from Jens Axboe:
"I wasn't going to send this one off so soon, but unfortunately one of
the fixes from the previous pull broke the build on some archs. So I'm
sending this sooner rather than later. This contains:
- Add highmem.h include for io_uring, because of the kmap() additions
from last round. For some reason the build bot didn't spot this
even though it sat for days.
- Three minor ';' removals
- Add support for the Beurer CD-on-a-chip device
- Make io_uring work on MMU-less archs"
* tag 'for-linus-20191129' of git://git.kernel.dk/linux-block:
io_uring: fix missing kmap() declaration on powerpc
ataflop: Remove unneeded semicolon

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace.
After clear input from the RaspberryPi and Beagle communities, it
has been established that prototyping, industrial automation and
make communities strongly need this feature, and as we want people
to use the character device, we have implemented the simple pull
up/down interface for GPIO lines.
This means we can specify that a (chip-specific) pull up/down
resistor can be enabled, but does not offer fine-grained control
such as cases where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out the
old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it in all
GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when cooperating with
the pin control subsystem and registering ranges as part of adding
a gpiolib driver and a gpio_irq_chip driver at the same time. This
is also deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained handler"
