Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

On error, kthread_create() returns an errno-encoded pointer, not NULL.
The routine qla2x00_probe_one() detects the error case and jumps to
probe_failed, but has already assigned the return value from
kthread_create() to ha->dpc_thread. Then probe_failed checks to see if
ha->dpc_thread is not NULL before doing cleanup on it. Since in the
error case this is also not NULL, it ends up trying to access an invalid
task pointer.
Solution is to assign NULL to ha->dpc_thread in the error path to avoid
kthread cleanup in that case.

If there are IO's running and host reset or chip reset is triggered,
IO's can fail due to rport time out. During chip reset recovery process,
driver notifies the transport layer that remote port no longer exist, by
calling fc_remote_port_delete(). When this function is called, it
actually delays deletion by "blocking" it. It sets the remote port state
to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When
driver tries to abort the command by calling its abort handler function,
abort handler will wait until remote port state is blocked state or wait
for dev_loss_tmo time. Due to this blocking, rport times out and results
in an IO failure. This patch adds a check for any active reset process
before calling abort handler function.

Currently, the driver performs the PLOGI/PRLI together as one operation,
but if the discovered port is an NVMe port then we first issue the PLOGI
and then we issue the PRLI. Also, the fabric discovery logic was changed

Thirteen small fixes: The hopefully final effort to get the lpfc nvme
kconfig problems sorted, there's one important sg fix (user can induce
read after end of buffer) and one minor enhancement (adding an extra
PCI ID to qedi). The rest are a set of minor fixes, which mostly occur
as user visible in error legs or on specific devices.

Current driver wait for FW to be in the ready state before
processing in-coming commands. For Arbitrated Loop or
Point-to- Point (not switch), FW Ready state can take a while.
FW will transition to ready state after all Nports have been
logged in. In the mean time, certain initiators have completed
the login and starts IO. Driver needs to start processing all
queues if FW is already started.

For target mode, when new scsi command arrive, driver first performs
a look up of the SCSI Host. The current look up method is based on
the ALPA portion of the NPort ID. For Cisco switch, the ALPA can
not be used as the index. Instead, the new search method is based
on the full value of the Nport_ID via btree lib.

After a Qlogic card breaks when initializing (test case), the system can
crash in qla2xxx_eh_abort if processing anything but a scsi command type
srb.
