of_pci_iommu_init() tries to be clever and stop its alias walk at the
device represented by master_np, in case of weird PCI topologies where
the bridge to the IOMMU and the rest of the system is not at the root.
It turns out this is a bit short-sighted, since there are plenty of
other callers of pci_for_each_dma_alias() which would also need the same
behaviour in that situation, and the only platform so far with such a
topology (Cavium ThunderX2) already solves it more generally via a PCI
quirk. As this check is effectively redundant, and returning a boolean
value as an int is a bit broken anyway, let's just get rid of it.

There is a check to see if pmlmepriv is null before vfree'ing
pmlmepriv->free_bss_buf hence implying pmlmepriv could potenially be
null. However, a previous call to rtw_free_mlme_priv_ie_data
can also dereference pmlmepriv, so move this call so that it is only
called if pmlmepriv non-null.

The value of the u8 id needs to be upper bounds checked to ensure
the cam_cache array on the adapter dvobj is not indexed outside
of the allowed range of 0..TOTAL_CAM_ENTRY-1. This can currently
occur if id is >= TOTAL_CAM_ENTRY when calling write_cam_from_cache.
Fix this by adding an upper range check.

Till recently the expected length of bytes read by the
daemon did depend on the context. It was either hv_start_fcopy or
hv_do_fcopy. The daemon had a buffer size of two pages, which was much
larger than needed.
Now the expected length of bytes read by the
daemon changed slightly. For START_FILE_COPY it is still the size of
hv_start_fcopy. But for WRITE_TO_FILE and the other operations it is as
large as the buffer that arrived via vmbus. In case of WRITE_TO_FILE
that is slightly larger than a struct hv_do_fcopy. Since the buffer in
the daemon was still larger everything was fine.
Currently, the daemon reads only what is actually needed.
The new buffer layout is as large as a struct hv_do_fcopy, for the
WRITE_TO_FILE operation. Since the kernel expects a slightly larger
size, hvt_op_read will return -EINVAL because the daemon will read
slightly less than expected. Address this by restoring the expected
buffer size in case of WRITE_TO_FILE.

Due to commit 54a66265d675 ("Drivers: hv: vmbus: Fix rescind handling"),
we need this patch to resolve the below deadlock:
after we get the mutex in vmbus_hvsock_device_unregister() and call
vmbus_device_unregister() -> device_unregister() -> ... -> device_release()
-> vmbus_device_release(), we'll get a deadlock, because
vmbus_device_release() tries to get the same mutex.

For reasons unknown, the stm_source removal path uses device_destroy()
to kill the underlying device object. Because device_destroy() uses
devt to look for the device to destroy and the fact that stm_source
devices don't have one (or all have the same one), it just picks the
first device in the class, which may well be the wrong one.
That is, loading stm_console and stm_heartbeat and then removing both
will die in dereferencing a freed object.
Since this should have been device_unregister() in the first place,
use it instead of device_destroy().

Ever since commit a621bac3044e ("scsi_lib: correctly retry failed zero
length REQ_TYPE_FS commands"), people have been getting bogus error
messages for USB disk drives using ATA pass-thru. For example:
[ 1344.880193] sd 6:0:0:0: [sdb] Attached SCSI disk
[ 1345.069152] sd 6:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE

[ 1345.069162] sd 6:0:0:0: [sdb] tag#0 Add. Sense: No additional sense information
[ 1345.069168] sd 6:0:0:0: [sdb] tag#0 CDB: ATA command pass through(16) 85 06 20 00 00 00 00 00 00 00 00 00 00 00 e5 00
[ 1345.172252] sd 6:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE
[ 1345.172258] sd 6:0:0:0: [sdb] tag#0 Sense Key : Hardware Error [current] [descriptor]
[ 1345.172261] sd 6:0:0:0: [sdb] tag#0 Add. Sense: No additional sense information
[ 1345.172266] sd 6:0:0:0: [sdb] tag#0 CDB: ATA command pass through(12)/Blank a1 06 20 da 00 00 4f c2 00 b0 00 00
These messages can be quite annoying, because programs like udisks2
provoke them every 10 minutes or so. Other programs can also have
this effect, such as those in smartmontools.
I don't fully understand how that commit induced the SCSI core to log
these error messages, but the underlying cause for them is code added
to usb-storage by commit f1a0743bc0e7 ("USB: storage: When a device
returns no sense data, call it a Hardware Error"). At the time it was
necessary to do this, in order to prevent an infinite retry loop with
some not-so-great mass storage devices.
However, the ATA pass-thru protocol uses SCSI sense data to return
command status values, and some devices always report Check Condition
status for ATA pass-thru commands to ensure that the host retrieves
the sense data, even if the command succeeded. This violates the USB
mass-storage protocol (Check Condition status is supposed to mean the
command failed), but we can't help that.
This patch attempts to mitigate the problem of these bogus error
reports by changing usb-storage. The HARDWARE ERROR sense key will be
inserted only for commands that aren't ATA pass-thru.
Thanks to Ewan Milne for pointing out that this mechanism was present
in usb-storage. 8 years after writing it, I had completely forgotten
its existence.

While we could solve this by simply initializing the completion earlier, we
are better off rearranging the code a bit so we avoid calling complete() on
requests that we did not send out. This patch consolidates marking request
slots as free in one place (in uinput_request_submit(), the same place
where we acquire them) and having everyone else simply signal completion
of the requests.

Normally, when input device supporting force feedback effects is being
destroyed, we try to "flush" currently playing effects, so that the
physical device does not continue vibrating (or executing other effects).
Unfortunately this does not work well for uinput as flushing of the effects
deadlocks with the destroy action:
- if device is being destroyed because the file descriptor is being closed,
then there is noone to even service FF requests;
- if device is being destroyed because userspace sent UI_DEV_DESTROY,
while theoretically it could be possible to service FF requests,
userspace is unlikely to do so (they'd need to make sure FF handling
happens on a separate thread) even if kernel solves the issue with FF
ioctls deadlocking with UI_DEV_DESTROY ioctl on udev->mutex.
To avoid lockups like the one below, let's install a custom input device
flush handler, and avoid trying to flush force feedback effects when we
destroying the device, and instead rely on uinput to shut off the device
properly.

The EMAC has the option of sending only a single pause frame when
flow control is enabled and the RX queue is full. Although sending
only one pause frame has little value, this would allow admins to
enable automatic flow control without having to worry about the EMAC
flooding nearby switches with pause frames if the kernel hangs.
The option is enabled by using the single-pause-mode private flag.

If MTU is changed the host would reject the send buffer change.
This problem is result of recent change to allow changing send
buffer size.
Every time we change the MTU, we store the previous net_device section
count before destroying the buffer, but we don’t store the previous
section size. When we reinitialize the buffer, its size is calculated
by multiplying the previous count and previous size. Since we
continuously increase the MTU, the host returns us a decreasing count
value while the section size is reinitialized to 1728 bytes every
time.
This eventually leads to a condition where the calculated buf_size is
so small that the host rejects it.

Memory to Memory transfers does not have any special alignment needs
regarding to acnt array size, but if one of the areas are in memory mapped
regions (like PCIe memory), we need to make sure that the acnt array size
is aligned with the mem copy parameters.
Before "dmaengine: edma: Optimize memcpy operation" change the memcpy was set
up in a different way: acnt == number of bytes in a word based on
__ffs((src | dest | len), bcnt and ccnt for looping the necessary number of
words to comlete the trasnfer.
Instead of reverting the commit we can fix it to make sure that the ACNT size
is aligned to the traswnfer.

cdc_parse_cdc_header function. He writes:
It looks like cdc_parse_cdc_header() doesn't validate buflen
before accessing buffer[1], buffer[2] and so on. The only check
present is while (buflen > 0).
So fix this issue up by properly validating the buffer length matches
what the descriptor says it is.

The probe function calls omap_gpio_show_rev(), which on most
compilers is inlined, but on the old gcc-4.6 is not, causing
a valid warning about the incorrect __init annotation:
WARNING: vmlinux.o(.text+0x40f614): Section mismatch in reference from the function omap_gpio_probe() to the function .init.text:omap_gpio_show_rev()
The function omap_gpio_probe() references
the function __init omap_gpio_show_rev().
This is often because omap_gpio_probe lacks a __init
annotation or the annotation of omap_gpio_show_rev is wrong.
This removes the __init.

size can be any u16 less than 128. If tc queue size is 5, we
set the rss_size to 8, indirection table will be used to limit
the size of actual queue size.
It may cause dropping of receiving packet in hardware if
rss_size is not set correctly.
For now, each TC has the same rss size.
