Most Logitech wireless keyboard and mice using the 27 MHz are hidpp10
devices, add support to logitech-dj for their receivers.
Doing so leads to 2 improvements:
1) All these devices share the same USB product-id for their receiver,
making it impossible to properly map some special keys / buttons
which differ from device to device. Adding support to logitech-dj to
see these as hidpp10 devices allows us to get the actual device-id
from the keyboard / mouse.
2) It enables battery-monitoring of these devices
This patch uses a new HID group for 27Mhz devices, since the logitech-hidpp
code needs to be able to differentiate them from other devices instantiated
by the logitech-dj code.

This receiver is almost identical to the normal unifying ones except:
- it is supposed to be paired to only one device (for performance reasons)
- the mice reports have a greater ranges in their values, so they are
using a different report ID.
Tested on a G403 and a G900.

We emulate the DJ functionality through the driver.
The receiver supports "fake device arrival" which behaves
like the probing of DJ devices.
A non-unifying receiver has 2 USB interfaces, the first one generates
standard keypresses and is compatible with the USB Keyboard Boot Subclass.
The second interface sends events for the mouse and special keys such as
the consumer-page keys. Events are split this way for BIOS / Windows /
generic-hid driver compatibility. This split does not actually match with
which device the event originate from, e.g. the consumer-page key events
originate from the keyboard but are delivered on the mouse interface.
To make sure the events are actually delivered to the dj_device
representing the originating device, we pick which dj_dev to forward
a "regular" input-report to based on the report-number, rather
then based on the originating interface.

Add a logi_dj_recv_queue_unknown_work helper and implement query
rate-limiting inside this helper.
The motivations behind this are:
1) We need to queue workitems for reports with no place to forward them
from more places with the upcoming non-unifying receiver support, hence
the addition of the helper function.
2) When we've missed a pairing info report (or there is a race between
the report and input-events) and the input report is e.g. from a mouse
being moved, we will get a lot of these before we've finished (re-)
querying and enumerating the devices, hence the rate-limiting.
Note this also removes the:
if (!djrcv_dev->paired_dj_devices[hidpp_report->device_index])
check previously guarding the sending of an unknown workitem, the caller
of logi_dj_recv_queue_notification already does this check before calling
logi_dj_recv_queue_notification.

dj/HID++ receivers are really a single logical entity, but for BIOS/Windows
compatibility they have multiple USB interfaces. For the upcoming
non-unifying receiver support, we need to listen for events from / bind to
all USB-interfaces of the receiver.
This commit add support to the logitech-dj code for creating a single
dj_receiver_dev struct for all interfaces belonging to a single
USB-device / receiver, in preparation for adding non-unifying receiver
support.

For the upcoming non-unifying receiver support, we are going to bind to
all USB-interfaces of a receiver, sharing a single struct dj_receiver_dev
between the interfaces. This means that dj_receiver_dev will contain
multiple pointers to a struct hid_device. Rename the current hdev member
to hidpp to prepare for this.
While at it switch dev_err calls which we are touching anyways from
dev_err to hid_err.

logi_dj_recv_forward_hidpp() is more generic at forwarding random HID

Widen the incore inode's i_delayed_blks counter to be a 64-bit integer.
This is necessary to fix an integer overflow problem that can be
reproduced easily now that we use the counter to track blocks that are
assigned to the inode in memory but not on disk. This includes actual
delalloc reservations as well as real extents in the COW fork that
are waiting to be remapped into the data fork.
These 'delayed mapping' blocks can easily exceed 2^32 blocks if one
creates a very large sparse file of size approximately 2^33 bytes with
one byte written every 2^23 bytes, sets a very large COW extent size
hint of 2^23 blocks, reflinks the first file into a second file, and
then writes a single byte every 2^23 blocks in the original file.
When this happens, we'll try to create approximately 1024 2^23 extent
reservations in the COW fork, which will overflow the counter and cause
problems.
Note that on x64 we end up filling a 4-byte gap in the structure so this
doesn't increase the incore size.

Dave Chinner noticed that xfs_file_dio_aio_write returns EAGAIN without
dropping the IOLOCK when its deciding not to wait, which means that we
leak the IOLOCK there. Since we now make unaligned directio always
wait, we have the opportunity to bail out before trying to take the
lock, which should reduce the overhead of this never-gonna-work case
considerably while also solving the dropped lock problem.

Change the way how pgd_offset, p4d_offset, pud_offset and pmd_offset
walk the page tables. pgd_offset now always calculates the index for
the top-level page table and adds it to the pgd, this is either a
segment table offset for a 2-level setup, a region-3 offset for 3-levels,
region-2 offset for 4-levels, or a region-1 offset for a 5-level setup.
The other three functions p4d_offset, pud_offset and pmd_offset will
only add the respective offset if they dereference the passed pointer.
With the new way of walking the page tables a sequence like this from
mm/gup.c now works:
pgdp = pgd_offset(current->mm, addr);
pgd = READ_ONCE(*pgdp);
p4dp = p4d_offset(&pgd, addr);
p4d = READ_ONCE(*p4dp);
pudp = pud_offset(&p4d, addr);
pud = READ_ONCE(*pudp);
pmdp = pmd_offset(&pud, addr);
pmd = READ_ONCE(*pmdp);

bio_add_page() and __bio_add_page() are capable of adding pages into
bio, and now we have at least two such usages alreay:
- __bio_iov_bvec_add_pages()
- nvmet_bdev_execute_rw().
So update comments on these two helpers.
The thing is a bit special for __bio_try_merge_page(), given the caller
needs to know if the new added page is same with the last added page,
then it isn't safe to pass multi-page in case that 'same_page' is true,
so adds warning on potential misuse, and updates comment on
__bio_try_merge_page().

The revised I/O ordering section of memory-barriers.txt introduced in
4614bbdee357 ("docs/memory-barriers.txt: Rewrite "KERNEL I/O BARRIER
EFFECTS" section") loosely refers to "the CPU", whereas the ordering
guarantees generally apply within a thread of execution that can migrate
between cores, with the scheduler providing the relevant barrier
semantics.
Reword the section to refer to "CPU thread" and call out ordering of
MMIO writes separately from ordering of writes to memory. Ben also
spotted that the string accessors are native-endian, so fix that up too.

Uncore PMU drivers face an awkward cyclic dependency wherein:
- They have to pick a valid online CPU to associate with before
registering the PMU device, since it will get exposed to userspace
immediately.
- The PMU registration has to be be at least partly complete before
hotplug events can be handled, since trying to migrate an
uninitialised context would be bad.
- The hotplug handler has to be ready as soon as a CPU is chosen, lest
it go offline without the user-visible cpumask value getting updated.
The arm-cci driver has tried to solve this by using get_cpu() to pick
the current CPU and prevent it from disappearing while both
registrations are performed, but that results in taking mutexes with
preemption disabled, which makes certain configurations very unhappy:
[ 1.983337] BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:2004

It is not feasible to resolve all the possible races outside of the perf
core itself, so address the immediate bug by following the example of
nearly every other PMU driver and not even trying to do so. Registering
the hotplug notifier first should minimise the window in which things
can go wrong, so that's about as much as we can reasonably do here. This
also revealed an additional race in assigning the global pointer too
late relative to the hotplug notifier, which gets fixed in the process.

In the event that the start address of the initrd is not aligned, but
has an aligned size, the base + size will not cover the entire initrd
image and there is a chance that the kernel will corrupt the tail of the
image.
By aligning the end of the initrd to a page boundary and then
subtracting the adjusted start address the memblock reservation will
cover all pages that contains the initrd.

The strcpy() function is being deprecated. Replace it by the safer
strscpy() and fix the following Coverity warnings:
"You might overrun the 15-character fixed-size string event->bus_id
by copying bus_id without checking the length."
"You might overrun the 20-character fixed-size string event->device_class
by copying device_class without checking the length."
