Obtain SFP modules temperatures through MTMP register instead of MTBR
register, because the first one utilizes shorter transaction buffer size
for request. It improves performance in case low frequency interface

The driver core first registers with the hwmon and thermal subsystems
and only then proceeds to initialize the switch driver (e.g.,
mlxsw_spectrum). It is only during the last stage that the current
firmware version is validated and a newer one flashed, if necessary.
The above means that if a new firmware feature is utilized by the
hwmon/thermal code, the driver will not be able to load.
Solve this by re-ordering initializing the switch driver before
registering with the hwmon and thermal subsystems.

Current implementation uses fixed size of I2C data transaction buffer.
Allow to set size of I2C transactions according to I2C physical adapter
capability. For that purpose adapter read and write size is obtained
from the I2C physical adapter and buffer size is set according to the
minimum of these two values. If adapter does not provide such info,
default buffer size is to be used.
It allows to improve performance of I2C access to silicon when long

When a waiter is waked by CB_NOTIFY_LOCK, it will retry
nfs4_proc_setlk(). The waiter may fail to nfs4_proc_setlk() and sleep
again. However, the waiter is already removed from clp->cl_lock_waitq
when handling CB_NOTIFY_LOCK in nfs4_wake_lock_waiter(). So any
subsequent CB_NOTIFY_LOCK won't wake this waiter anymore. We should
put the waiter back to clp->cl_lock_waitq before retrying.

Commit b7dbcc0e43 "NFSv4.1: Fix a race where CB_NOTIFY_LOCK fails to wake a waiter"
found this bug. However it didn't fix it.
This commit replaces schedule_timeout() with wait_woken() and
default_wake_function() with woken_wake_function() in function
nfs4_retry_setlk() and nfs4_wake_lock_waiter(). wait_woken() uses
memory barriers in its implementation to avoid potential race condition
when putting a process into sleeping state and then waking it up.

The TCP option parsing routines in tcp_parse_options function could
read one byte out of the buffer of the TCP options.
1 while (length > 0) {
2 int opcode = *ptr++;
3 int opsize;

5 switch (opcode) {
6 case TCPOPT_EOL:

8 case TCPOPT_NOP: /* Ref: RFC 793 section 3.1 */
9 length--;
10 continue;
11 default:
12 opsize = *ptr++; //out of bound access
If length = 1, then there is an access in line2.
And another access is occurred in line 12.
This would lead to out-of-bound access.
Therefore, in the patch we check that the available data length is
larger enough to pase both TCP option code and size.

The addition of rpc_check_timeout() to call_decode causes an Oops
when the RPCSEC_GSS credential is rejected.
The reason is that rpc_decode_header() will call xprt_release() in
order to free task->tk_rqstp, which is needed by rpc_check_timeout()
to check whether or not we should exit due to a soft timeout.
The fix is to move the call to xprt_release() into call_decode() so
we can perform it after rpc_check_timeout().

The smp_store_release call in fqdir_exit cannot protect the setting
of fqdir->dead as claimed because its memory barrier is only
guaranteed to be one-way and the barrier precedes the setting of
fqdir->dead.
IOW it doesn't provide any barriers between fq->dir and the following
hash table destruction.
In fact, the code is safe anyway because call_rcu does provide both
the memory barrier as well as a guarantee that when the destruction
work starts executing all RCU readers will see the updated value for
fqdir->dead.
Therefore this patch removes the unnecessary smp_store_release call
as well as the corresponding READ_ONCE on the read-side in order to
not confuse future readers of this code. Comments have been added
in their places.
