I know, it's a measly space, but I can't stand it since the
V4L2_PIX_FMT_NV24 case before this case does it right.
So add the space in order to restore blessed symmetry and
consistency and to make the world whole again...

find_format_by_index() stops enumerating formats as soon as the index
matches, and returns NULL if venus_helper_check_codec() finds out that
the format is not supported. This prevents formats to be properly
enumerated if a non-supported format is present, as the enumeration will
end with it.
Fix this by moving the call to venus_helper_check_codec() into the loop,
and keep enumerating when it fails.

Upon module load, mmc_block allocates a bus with bus_registeri() in
mmc_blk_init(). This reference never gets freed during module unload, which
leads to subsequent re-insertions of the module fails and a WARN() splat is
triggered.
Fix the bug by dropping the reference for the bus in mmc_blk_exit().

A spinlock is held while updating the internal copy of the IRQ mask,
but not while writing it to the actual IMASK register. After the lock
is released, an IRQ can occur before the IMASK register is written.
If handling this IRQ causes the mask to be changed, when the handler
returns back to the middle of the first mask update, a stale value
will be written to the mask register.
If this causes an IRQ to become unmasked that cannot have its status
cleared by writing a 1 to it in the IREG register, e.g. the SDIO IRQ,
then we can end up stuck with the same IRQ repeatedly being fired but
not handled. Normally the MMC IRQ handler attempts to clear any
unexpected IRQs by writing IREG, but for those that cannot be cleared
in this way then the IRQ will just repeatedly fire.
This was resulting in lockups after a while of using Wi-Fi on the
CI20 (GitHub issue #19).
Resolve by holding the spinlock until after the IMASK register has
been updated.

A single register of the controller holds the information for four dma
channels.
The functions stm32_dma_irq_status() don't mask the relevant bits after
the shift, thus adjacent channel's status is also reported in the returned
value.
Fixed by masking the value before returning it.
Similarly, the function stm32_dma_irq_clear() don't mask the input value
before shifting it, thus an incorrect input value could disable the
interrupts of adjacent channels.
Fixed by masking the input value before using it.

Having 0 in item counter register is valid and stands for a "No or Ended

If serial console wake-up is enabled ("echo enabled >
/sys/.../ttySC0/power/wakeup"), and any serial input is received while
the system is suspended, serial port input no longer works after system
resume.
Note that:
1) The system can still be woken up using the serial console,
2) Serial port input keeps working if the system is woken up in some
other way (e.g. Wake-on-LAN or gpio-keys), and no serial input was
received while suspended.
To fix this, replace SET_LATE_SYSTEM_SLEEP_PM_OPS() by
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS(), as the callbacks installed by the
former happen too early resp. late in the suspend resp. resume process.

Code is refactored to prepare separate functions for RoCE which can do more
complex operations related to reference counting, while still
maintainining code readability. This includes
(a) Simplification to not perform netdevice checks and modifications
for IB link layer.
(b) Do not add RoCE GID entry which has NULL netdevice; instead return
an error.
(c) If GID addition fails at provider level add_gid(), do not add the
entry in the cache and keep the entry marked as INVALID.
(d) Simplify and reuse the ib_cache_gid_add()/del() routines so that they
can be used even for modifying default GIDs. This avoid some code
duplication in modifying default GIDs.
(e) find_gid() routine refers to the data entry flags to qualify a GID
as valid or invalid GID rather than depending on attributes and zeroness
of the GID content.
(f) gid_table_reserve_default() sets the GID default attribute at
beginning while setting up the GID table. There is no need to use
default_gid flag in low level functions such as write_gid(), add_gid(),
del_gid(), as they never need to update the DEFAULT property of the GID
entry while during GID table update.
As as result of this refactor, reserved GID 0:0:0:0:0:0:0:0 is no longer
searchable as described below.
A unicast GID entry of 0:0:0:0:0:0:0:0 is Reserved GID as per the IB
spec version 1.3 section 4.1.1, point (6) whose snippet is below.
"The unicast GID address 0:0:0:0:0:0:0:0 is reserved - referred to as
the Reserved GID. It shall never be assigned to any endport. It shall
not be used as a destination address or in a global routing header
(GRH)."
GID table cache now only stores valid GID entries. Before this patch,
Reserved GID 0:0:0:0:0:0:0:0 was searchable in the GID table using
ib_find_cached_gid_by_port() and other similar find routines.
Zero GID is no longer searchable as it shall not to be present in GRH or
path recored entry as described in IB spec version 1.3 section 4.1.1,
point (6), section 12.7.10 and section 12.7.20.
ib_cache_update() is simplified to check link layer once, use unified
locking scheme for all link layers, removed temporary gid table
allocation/free logic.
Additionally,
(a) Expand ib_gid_attr to store port and index so that GID query
routines can get port and index information from the attribute structure.
(b) Expand ib_gid_attr to store device as well so that in future code when
GID reference counting is done, device is used to reach back to the GID
table entry.

Currently following inconsistencies exist.
1. ib_query_gid() returns GID from the software cache for a RoCE port
and returns GID from the HCA for an IB port.
This is incorrect because software GID cache is maintained regardless
of HCA port type.
2. GID is queries from the HCA via ib_query_gid and updated in the
software cache for IB link layer. Both of them might not be in sync.
ULPs such as SRP initiator, SRP target, IPoIB driver have historically
used ib_query_gid() API to query the GID. However CM used cached version
during CM processing, When software cache was introduced, this
inconsitency remained.
In order to simplify, improve readability and avoid link layer
specific above inconsistencies, this patch brings following changes.
1. ib_query_gid() always refers to the cache layer regardless of link
layer.
2. cache module who reads the GID entry from HCA and builds the cache,
directly invokes the HCA provider verb's query_gid() callback function.
3. ib_query_port() is being called in early stage where GID cache is not
yet build while reading port immutable property. Therefore it needs to
read the default GID from the HCA for IB link layer to publish the
subnet prefix.

ib_query_gid() fetches the GID from the software cache maintained in
ib_core for RoCE ports.
Therefore, simplify the provider drivers for RoCE to treat query_gid()
callback as never called for RoCE, and only require non-RoCE devices to
implement it.

qedr driver's add_gid() and del_gid() callbacks are doing simple
checks which are already done by the ib core before invoking these
callback routines.
Therefore, code is simplified to skip implementing add_gid() and
del_gid() callback functions.

This structure is pushed down the ex and the non-ex path, so it needs to be
aligned to 8 bytes to go through ex without implicit padding.
Old user space will provide 4 bytes of resp on !ex and 8 bytes on ex, so
take the approach of just copying the minimum length.
New user space will consistently provide 8 bytes in both cases.

This allows platforms that are CPU/memory contrained to verify data
blocks only the first time they are read from the data device, rather
than every time. As such, it provides a reduced level of security
because only offline tampering of the data device's content will be
detected, not online tampering.
Hash blocks are still verified each time they are read from the hash
device, since verification of hash blocks is less performance critical
than data blocks, and a hash block will not be verified any more after
all the data blocks it covers have been verified anyway.
This option introduces a bitset that is used to check if a block has
been validated before or not. A block can be validated more than once
as there is no thread protection for the bitset.
These changes were developed and tested on entry-level Android Go
devices.

The bio structure consumes a substantial part of dm_buffer. The bio
structure is only needed when doing I/O on the buffer, thus we don't
have to embed it in the buffer.
Allocate the bio structure only when doing I/O.
We don't need to create a bio_set because, in case of allocation
failure, dm-bufio falls back to using dm-io (which keeps its own
bio_set).

The I/O buffer doesn't have to be aligned on block size granularity,
relax alignment to ARCH_KMALLOC_MINALIGN (required to allow DMA from

Also, set SLAB_RECLAIM_ACCOUNT so that the memory allocated from the

dm-bufio keeps the dm_bufio_cache_names array that holds names of the
slab caches.
Since the commit db265eca7700 ("mm/sl[aou]b: Move duping of slab name to
slab_common.c"), the kernel automatically duplicates the slab cache name
when creating the slab cache, so we no longer have to keep the name
allocated.
Remove the code that allocates the slab names and keeps them around.

Move dm-bufio.h to include/linux/ so that external GPL'd DM target
modules can use it.
It is better to allow the use of dm-bufio than force external modules
to implement the equivalent buffered IO mechanism in some new way. The
hope is this will encourage the use of dm-bufio; which will then make it
easier for a GPL'd external DM target module to be included upstream.
A couple dm-bufio EXPORT_SYMBOL exports have also been updated to use
EXPORT_SYMBOL_GPL.
