Linux cifs mount with ntlmssp against an Mac OS X (Yosemite
10.10.5) share fails in case the clocks differ more than +/-2h:
digest-service: digest-request: od failed with 2 proto=ntlmv2
digest-service: digest-request: kdc failed with -1561745592 proto=ntlmv2
Fix this by (re-)using the given server timestamp for the
ntlmv2 authentication (as Windows 7 does).
A related problem was also reported earlier by Namjae Jaen (see below):
Windows machine has extended security feature which refuse to allow
authentication when there is time difference between server time and
client time when ntlmv2 negotiation is used. This problem is prevalent
in embedded enviornment where system time is set to default 1970.
Modern servers send the server timestamp in the TargetInfo Av_Pair
structure in the challenge message [see MS-NLMP 2.2.2.1]
In [MS-NLMP 3.1.5.1.2] it is explicitly mentioned that the client must
use the server provided timestamp if present OR current time if it is
not

R6 removed the Config4.MMUExtDef field, with the low 16 bits only
allowed to contain FTLB fields, and commit e87569cd6c ("MIPS:
cpu-probe: Fix VTLB/FTLB configuration for R6") updated the probing of
this field to assume an FTLB is always present for R6.
However the FTLB may still be absent. The presence of those fields is
actually specified by the MMU type in the Config.MT field, so use that
(the new cpu_has_ftlb) to determine whether the FTLB is actually
present.

Add cpu_has_ftlb, which specifies that an FTLB is present in addition to
the VTLB, probed based on whether Config.MT == 4 (rather than 1 for
standard JTLB).
This is necessary since MIPS release 6 removes Config4.MMUExtDef, so the
presence of the FTLB fields in Config4 must be determined from Config.MT
instead.

When dropping a snapshot we need to account for the qgroup changes. If we drop
the snapshot in all one go then the backref code will fail to find blocks from
the snapshot we dropped since it won't be able to find the root in the fs root
cache. This can lead to us failing to find refs from other roots that pointed
at blocks in the now deleted root. To handle this we need to not remove the fs
roots from the cache until after we process the qgroup operations. Do this by
adding dropped roots to a list on the transaction, and letting the transaction
remove the roots at the same time it drops the commit roots. This will keep all
of the backref searching code in sync properly, and fixes a problem Mark was
seeing with snapshot delete and qgroups. Thanks,

When a trace recorded on a 32-bit device is processed with a 64-bit
binary, the higher 32-bits of the address need to ignored.
The lack of this results in the output of the 64-bit pointer
value to the trace as the 32-bit address lookup fails in find_printk().
Before:
burn-1778 [003] 548.600305: bputs: 0xc0046db2s: 2cec5c058d98c
After:
burn-1778 [003] 548.600305: bputs: 0xc0046db2s: RT throttling activated
The problem occurs in PRINT_FIELD when the field is recognized as a
pointer to a string (of the type const char *)
Heterogeneous architectures cases below can arise and should be handled:
* Traces recorded using 32-bit addresses processed on a 64-bit machine
* Traces recorded using 64-bit addresses processed on a 32-bit machine

The current behavior of notifying CQM events is inconsistent:
Upon first configuration there is a cqm event with the current
status according to threshold configured, regardless of signal
stability.
When there is reconfiguration no event is sent unless there is
a significant change to the signal level according to the new
configuration.
Since the current reconfiguration behavior might cause missing
CQM events in case the current signal did not change but is on
the other side of the new threshold, fix that by resetting the
stored signal level upon reconfiguration.

Use the existing USB_SS_MULT() macro instead to make sure the mult value

"The threadgroup locking changes which went in during 4.2 devel cycle
added write locking of a percpu_rwsem in cgroup task migration path;
unfortunately, that involved expedited rcu syncing which turned out to
be too slow and heavy for certain workloads. The patchset which is
dependent on this one didn't get committed during that devel cycle, so
these two patches can be reverted safely.
Oleg reworked percpu_rwsem for 4.4 so that the writer path is a lot
lighter. The reported issue goes away with Oleg's reworked
percpu_rwsem and I'll reapply these patches on the for-4.4 branch so
that they can land together with Oleg's changes"

Before allowing lockless LISTEN processing, we need to make

When creating a timewait socket, we need to arm the timer before
allowing other cpus to find it. The signal allowing cpus to find
the socket is setting tw_refcnt to non zero value.
As we set tw_refcnt in __inet_twsk_hashdance(), we therefore need to
call inet_twsk_schedule() first.
This also means we need to remove tw_refcnt changes from
inet_twsk_schedule() and let the caller handle it.
Note that because we use mod_timer_pinned(), we have the guarantee
the timer wont expire before we set tw_refcnt as we run in BH context.
To make things more readable I introduced inet_twsk_reschedule() helper.
When rearming the timer, we can use mod_timer_pending() to make sure
we do not rearm a canceled timer.
Note: This bug can possibly trigger if packets of a flow can hit
multiple cpus. This does not normally happen, unless flow steering
is broken somehow. This explains this bug was spotted ~5 months after
its introduction.
A similar fix is needed for SYN_RECV sockets in reqsk_queue_hash_req(),
but will be provided in a separate patch for proper tracking.

There's a bunch of cheap USB 10/100 devices based on QinHeng chipsets. The
vendor driver supports the CH9100 and CH9200 devices, but the majority of
the code is of the if (ch9100) {} else {} form, with the most significant
difference being that CH9200 provides a real MII interface but CH9100 fakes
one with a bunch of global variables and magic commands. I don't have a
CH9100, so it's probably better if someone who does provides an independent
driver for it. In any case, this is a lightly cleaned up version of the
vendor driver with all the CH9100 code dropped.

net: phy: Fix module autoload for OF platform drivers
These patches add the missing MODULE_DEVICE_TABLE() for OF to export
the information so modules have the correct aliases built-in and
autoloading works correctly.
