ucmd in hns_roce_create_qp_common() are not initialized. But it works fine
until new member sdb_addr is added to struct hns_roce_ib_create_qp.
If the user-mode driver uses an old version ABI, then the value of the new
member will be undefined after ib_copy_from_udata().
This patch fixes it by initialize this variable to 0. And the default value
of the new member sdb_addr will be 0 which is invalid.

The current driver will print all asynchronous events. Some of the
print levels are set improperly, e.g. SRQ limit reach and SRQ last
wqe reach, which may also occur during normal operation of the software.
Currently, the information of these event is printed as a warning,
which causes a large amount of printing even during normal use of the
application. As a result, the service performance deteriorates.
This patch fixes the printing storms by modifying the print level.

Previously when we had a RAW QP, we bound a counter to it when it moved
to INIT state, using the counter context inside RQC.
But when we try to modify that counter later in RTS state we used
modify QP which tries to change the counter inside QPC instead of RQC.
Now we correctly modify the counter set_id inside of RQC instead of QPC
for the RAW QP.

memset() description in ISO/IEC 9899:1999 (and elsewhere) says:
The memset function copies the value of c (converted to an
unsigned char) into each of the first n characters of the
object pointed to by s.
The kernel's arm32 memset does not cast c to unsigned char. This results
in the following code to produce erroneous output:
char a[128];
memset(a, -128, sizeof(a));
This is because gcc will generally emit the following code before
it calls memset() :
mov r0, r7
mvn r1, #127 ; 0x7f
bl 00000000 <memset>
r1 ends up with 0xffffff80 before being used by memset() and the
'a' array will have -128 once in every four bytes while the other
bytes will be set incorrectly to -1 like this (printing the first
8 bytes) :
test_module: -128 -1 -1 -1
test_module: -1 -1 -1 -128
The change here is to 'and' r1 with 255 before it is used.

The function adf_dev_init(), through the subsystem qat_crypto, populates
the list of list of crypto instances accel_dev->crypto_list.
If the list of instances is not empty, the function adf_dev_start() will
then call qat_algs_registers() and qat_asym_algs_register() to register
the crypto algorithms into the crypto framework.
If any of the functions in adf_dev_start() fail, the caller of such
function, in the error path calls adf_dev_down() which in turn call
adf_dev_stop() and adf_dev_shutdown(), see for example the function
state_store in adf_sriov.c.
However, if the registration of crypto algorithms is not done,
adf_dev_stop() will try to unregister the algorithms regardless.
This might cause the counter active_devs in qat_algs.c and
qat_asym_algs.c to get to a negative value.
Add a new state, ADF_STATUS_CRYPTO_ALGS_REGISTERED, which tracks if the
crypto algorithms are registered into the crypto framework. Then use
this to unregister the algorithms if such flag is set. This ensures that
the crypto algorithms are only unregistered if previously registered.

vmalloc() for zstd decompression workspace") and replace kmalloc() with
vmalloc() also for the gzip module decompression workspace.
In this case the workspace is represented by struct inflate_workspace
that can be fairly large for kmalloc() and it can potentially lead to
allocation errors on certain systems:
$ pahole inflate_workspace
struct inflate_workspace {
struct inflate_state inflate_state; /* 0 9544 */
/* --- cacheline 149 boundary (9536 bytes) was 8 bytes ago --- */
unsigned char working_window[32768]; /* 9544 32768 */
/* size: 42312, cachelines: 662, members: 2 */
/* last cacheline: 8 bytes */
};
Considering that there is no need to use continuous physical memory,
simply switch to vmalloc() to provide a more reliable in-kernel module
decompression.

Benchmark command is copied into an array in the stack. The array is
BENCHMARK_ARGS items long but the command line could try to provide a
longer command. Argument size is also fixed by BENCHMARK_ARG_SIZE (63
bytes of space after fitting the terminating \0 character) and user
could have inputted argument longer than that.
Return error in case the benchmark command does not fit to the space

[ Upstream commit 4d7f4e8158b62f63031510cdc24acc520956c091 ]
Compiling pidfd selftest after adding a __printf() attribute to
ksft_print_msg() and ksft_test_result_pass() exposes -Wformat warnings
in error_report(), test_pidfd_poll_exec_thread(),
child_poll_exec_test(), test_pidfd_poll_leader_exit_thread(),
child_poll_leader_exit_test().
The ksft_test_result_pass() in error_report() expects a string but
doesn't provide any argument after the format string. All the other
calls to ksft_print_msg() in the functions mentioned above have format
strings that don't match with other passed arguments.
Fix format specifiers so they match the passed variables.
Add a missing variable to ksft_test_result_pass() inside
error_report() so it matches other cases in the switch statement.

An FF-A ABI could support both the SMC32 and SMC64 conventions.
A callee that runs in the AArch64 execution state and implements such
an ABI must implement both SMC32 and SMC64 conventions of the ABI.
So the FF-A drivers will need the option to choose the mode irrespective
of FF-A version and the partition execution mode flag in the partition
information.
Let us remove the check on the FF-A version for allowing the selection
of 32bit mode of messaging. The driver will continue to set the 32-bit
mode if the partition execution mode flag specified that the partition
supports only 32-bit execution.

Commit 19b8766459 ("firmware: arm_ffa: Fix FFA device names for logical
partitions") added an ID to the FFA device using ida_alloc() and append
the same to "arm-ffa" to make up a unique device name. However it missed
to stash the id value in ffa_dev to help freeing the ID later when the
device is destroyed.
Due to the missing/unassigned ID in FFA device, we get the following
warning when the FF-A device is unregistered.

The TI-SCI message protocol provides a way to communicate between
various compute processors with a central system controller entity. It
provides the fundamental device management capability and clock control
in the SOCs that it's used in.
The remove function failed to do all the necessary cleanup if
there are registered users. Some things are freed however which
likely results in an oops later on.
Ensure that the driver isn't unbound by suppressing its bind and unbind
sysfs attributes. As the driver is built-in there is no way to remove
device once bound.
We can also remove the ti_sci_remove call along with the
ti_sci_debugfs_destroy as there are no callers for it any longer.
