6eaa77144b scsi: mpt3sas: Fix mpt3sas_check_same_4gb_region() kdoc comment
The start_addres argument of mpt3sas_check_same_4gb_region() was misnamed
in the function kdoc comment, resulting in the following warning when
compiling with W=1.

drivers/scsi/mpt3sas/mpt3sas_base.c:5728: warning: Function parameter or
member 'start_address' not described in 'mpt3sas_check_same_4gb_region'
drivers/scsi/mpt3sas/mpt3sas_base.c:5728: warning: Excess function

Fix the argument name in the function kdoc comment to avoid it. While at
it, remove a useless blank line between the kdoc and function code.

This reverts commit 7dabfa2bc4. There are
multiple reports that this breaks boot on various systems. The common
theme is that orphan clks are having rates set on them when that isn't
expected. Let's revert it out for now so that -rc1 boots.

5291984004 dm: fix bio polling to handle possibile BLK_STS_AGAIN
Expanded testing of DM's bio polling support (using more fio threads
to dm-linear ontop of null_blk) exposed the possibility for polled
bios to hang (repeatedly polling in io_uring) when null_blk responds
with BLK_STS_AGAIN (due to lack of resources):

1) io_complete_rw_iopoll() is called from blkdev_bio_end_io_async() to
   notify kiocb is done, that is the completion interface between block
   layer and io_uring

2) io_complete_rw_iopoll() is called from io_do_iopoll()

3) dm returns BLK_STS_AGAIN for one bio (on behalf of underlying
   driver), then io_complete_rw_iopoll is called, but io_do_iopoll()
   doesn't handle -EAGAIN at all (due to logic in io_rw_should_reissue)

4) reason for dm's BLK_STS_AGAIN is underlying null_blk driver ran out
   of requests (easier to reproduce by setting low hw_queue_depth).

5) dm should handle BLK_STS_AGAIN for POLLED underlying IO, and may
   retry in dm layer.

This fix adds REQ_POLLED specific BLK_STS_AGAIN handling to
dm_io_complete() that clears REQ_POLLED and requeues the bio to DM
using queue_io().

aad5b23ebf dm: fix dm_io and dm_target_io flags race condition on Alpha
Early alpha processors cannot write a single byte or short; they read 8
bytes, modify the value in registers and write back 8 bytes.

This could cause race condition in the structure dm_io - if the fields
flags and io_count are modified simultaneously.

Fix this bug by using 32-bit flags if we are on Alpha and if we are
compiling for a processor that doesn't have the byte-word-extension.

Commit f6f72f32c2 ("dm integrity: don't replay journal data past the

beyond the end of the device. Unfortunatelly, it doesn't set the
journal entry unused, which resulted in this BUG being triggered:
BUG_ON(!journal_entry_is_unused(je))

Fix this by calling journal_entry_set_unused() for this case.

8b188fba75 Revert "Input: clear BTN_RIGHT/MIDDLE on buttonpads"
This reverts commit 37ef4c19b4.

The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.

In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:

	[Precision 7x50 Touchpad]
	MatchBus=i2c
	MatchUdevType=touchpad
	MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
	AttrInputPropDisable=INPUT_PROP_BUTTONPAD

However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.

In order to avoid breakage on other present or future devices, revert
the patch causing the issue.

 remove_wait_queue
 ep_unregister_pollwait

 do_epoll_ctl

A Python example to reproduce the issue:
... import select
... p = select.epoll()
... f = open('/sys/kernel/debug/cros_scp/console_log')
... p.register(f, select.POLLIN)
... p.poll(1)
[(4, 1)]                    # 4=fd, 1=select.POLLIN

[ shutdown cros_scp at the point ]

... p.poll(1)
[(4, 16)]                   # 4=fd, 16=select.POLLHUP
... p.unregister(f)

An use-after-free issue raises here.  It called epoll_ctl with
EPOLL_CTL_DEL which in turn to use the workqueue in the devm (i.e.
log_wq).

Detaches log reader's workqueue from devm to make sure it is persistent
even if the device has been removed.

eabd9a3807 platform: chrome: Split trace include file
cros_ec_trace.h defined 5 tracing events, 2 for cros_ec_proto and
3 for cros_ec_sensorhub_ring.
These 2 files are in different kernel modules, the traces are defined
twice in the kernel which leads to problem enabling only some traces.

Move sensorhub traces from cros_ec_trace.h to cros_ec_sensorhub_trace.h
and enable them only in cros_ec_sensorhub kernel module.

Check we can now enable any single traces: without this patch,
we can only enable all sensorhub traces or none.

2651ee5ae4 drbd: remove check of list iterator against head past the loop body
When list_for_each_entry() completes the iteration over the whole list
without breaking the loop, the iterator value will be a bogus pointer
computed based on the head element.

While it is safe to use the pointer to determine if it was computed
based on the head element, either with list_entry_is_head() or
&pos->member == head, using the iterator variable after the loop should
be avoided.

In preparation to limit the scope of a list iterator to the list
traversal loop, use a dedicated pointer to point to the found element [1].

901aeda62e drbd: remove usage of list iterator variable after loop
In preparation to limit the scope of a list iterator to the list
traversal loop, use a dedicated pointer to iterate through the list [1].

Since that variable should not be used past the loop iteration, a
separate variable is used to 'remember the current location within the
loop'.

To either continue iterating from that position or skip the iteration
(if the previous iteration was complete) list_prepare_entry() is used.

Pull random number generator fixes from Jason Donenfeld:

 - If a hardware random number generator passes a sufficiently large
   chunk of entropy to random.c during early boot, we now skip the
   "fast_init" business and let it initialize the RNG.

   This makes CONFIG_RANDOM_TRUST_BOOTLOADER=y actually useful.

 - We already have the command line `random.trust_cpu=0/1` option for
   RDRAND, which let distros enable CONFIG_RANDOM_TRUST_CPU=y while
   placating concerns of more paranoid users.

   Now we add `random.trust_bootloader=0/1` so that distros can
   similarly enable CONFIG_RANDOM_TRUST_BOOTLOADER=y.

 - Re-add a comment that got removed by accident in the recent revert.

 - Add the spec-compliant ACPI CID for vmgenid, which Microsoft added to
   the vmgenid spec at Ard's request during earlier review.

 - Restore build-time randomness via the latent entropy plugin, which
   was lost when we transitioned to using a hash function.

1754abb3e7 random: mix build-time latent entropy into pool at init
Prior, the "input_pool_data" array needed no real initialization, and so
it was easy to mark it with __latent_entropy to populate it during
compile-time. In switching to using a hash function, this required us to
specifically initialize it to some specific state, which means we
dropped the __latent_entropy attribute. An unfortunate side effect was
this meant the pool was no longer seeded using compile-time random data.
In order to bring this back, we declare an array in rand_initialize()
with __latent_entropy and call mix_pool_bytes() on that at init, which
accomplishes the same thing as before. We make this __initconst, so that
it doesn't take up space at runtime after init.

handler for m_can IP cores v3.0.x.

error path of the xmit handler in the ems_usb, usb_8dev and mcba_usb
USB CAN driver.

9c9a04212f net: hns3: fix the concurrency between functions reading debugfs
Currently, the debugfs mechanism is that all functions share a
global variable to save the pointer for obtaining data. When
different functions concurrently access the same file node,
repeated release exceptions occur. Therefore, the granularity
of the pointer for storing the obtained data is adjusted to be
private for each function.

50d34a0d15 can: gs_usb: gs_make_candev(): fix memory leak for devices with extended bit timing configuration
Some CAN-FD capable devices offer extended bit timing information for
the data bit timing. The information must be read with an USB control
message. The memory for this message is allocated but not free()ed (in
the non error case). This patch adds the missing free.

136bed0bfd can: mcba_usb: properly check endpoint type
Syzbot reported warning in usb_submit_urb() which is caused by wrong
endpoint type. We should check that in endpoint is actually present to
prevent this warning.

Found pipes are now saved to struct mcba_priv and code uses them
directly instead of making pipes in place.
