4e9be65059 hwmon: (lis3lv02d) Convert SPI to dev_pm_ops
There is a move to deprecate bus-specific PM operations and move to
using dev_pm_ops instead in order to reduce the amount of boilerplate
code in buses and facilitiate updates to the PM core. Do this move for
the lis3lv02d SPI driver.

Much of ip_vs_leave() is unnecessary if CONFIG_SYSCTL is undefined.

I tried an approach of breaking the now #ifdef'ed portions out
into a separate function. However this appeared to grow the
compiled code on x86_64 by about 200 bytes in the case where
CONFIG_SYSCTL is defined. So I have gone with the simpler though
less elegant #ifdef'ed solution for now.

55a3d4e15c ipvs: properly zero stats and rates
Currently, the new percpu counters are not zeroed and
the zero commands do not work as expected, we still show the old
sum of percpu values. OTOH, we can not reset the percpu counters
from user context without causing the incrementing to use old
and bogus values.

 	So, as Eric Dumazet suggested fix that by moving all overhead
to stats reading in user context. Do not introduce overhead in
timer context (estimator) and incrementing (packet handling in
softirqs).

 	The new ustats0 field holds the zero point for all
counter values, the rates always use 0 as base value as before.
When showing the values to user space just give the difference
between counters and the base values. The only drawback is that
percpu stats are not zeroed, they are accessible only from /proc
and are new interface, so it should not be a compatibility problem
as long as the sum stats are correct after zeroing.

2a0751af09 ipvs: reorganize tot_stats
The global tot_stats contains cpustats field just like the
stats for dest and svc, so better use it to simplify the usage
in estimation_timer. As tot_stats is registered as estimator
we can remove the special ip_vs_read_cpu_stats call for
tot_stats. Fix ip_vs_read_cpu_stats to be called under
stats lock because it is still used as synchronization between
estimation timer and user context (the stats readers).

 	Also, make sure ip_vs_stats_percpu_show reads properly
the u64 stats from user context.

32f7ef7358 [SCSI] scsi_debug: add consecutive medium errors
A useful test case for error recovery is multiple,
consecutive medium errors. When scsi_debug is started
with "opts=2" a MEDIUM ERROR is generated when block
0x1234 (4660) is read. The patch extends that to
10 consecutive blocks from 0x1234 (i.e. blocks 4660 to
4669 inclusive).

[0:0:0:0]  disk  ATA    INTEL SSD  2CV1 /dev/sda /dev/sg0 80.0GB
[10:0:0:0] disk  Linux  scsi_debug 0004 /dev/sdb /dev/sg1 1.09TB

Output file not specified so no copy, just reading input
 >> unrecovered read error at blk=4660, substitute zeros
...
 >> unrecovered read error at blk=4669, substitute zeros
4670+10 records in
0+0 records out
10 unrecovered read errors
lowest unrecovered read lba=4660, highest unrecovered lba=4669
time to read data: 0.047943 secs at 49.87 MB/sec

BTW Change /dev/sg1 (bsg device works just as well) to
/dev/sdb to see why, with faulty media, you do not want
to use the block layer interface. Reason: time block
layer takes to do useless retries and collateral damage
to data in its 4 KB blocks (O_DIRECT mitigates the
latter).

ChangeLog:
    - extend opts=2 medium error generation at block
      0x1234 to 10 consecutive blocks (i.e. blocks
      0x1234 to 0x123d).

12a2856b60 macvlan : fix checksums error when we are in bridge mode
When the lower device has offloading capabilities, the packets checksums
are not computed. That leads to have any macvlan port in bridge mode to
not work because the packets are dropped due to a bad checksum.

If the macvlan is in bridge mode, the packet is forwarded to another
macvlan port and reach the network stack where it looks for a checksum
but this one was not computed due to the offloading of the lower device.
In this case, we have to set the packet with CHECKSUM_UNNECESSARY
when it is forwarded to a bridged port and restore the previous value of
ip_summed when the packet goes to the lowerdev.

a82058a730 [SCSI] libsas: fix ata list corruption issue
I think this stems from a misunderstanding of how the ata error handler
works.  ata_scsi_cmd_error_handler() gets called with a passed in list
of commands to handle.  However, that list may still not be empty when
it exits.  The command ata_scsi_port_error_handler() must be called
(which takes no list) before the list will be completely emptied.  This
bites the sas error handler because the two are called from different
functions and the original list has gone out of scope before
ata_scsi_port_error_handler() is called. leading to some commands
dangling on bare stack, which is a potential memory corruption issue.
Fix this by manually deleting all outstanding commands from the on-stack
list before it goes out of scope.

bea3864fb6 PM / Hibernate: Reduce autotuned default image size
The hibernate image size autotuning mechanism sets the default
image size to 5/2 of the total system RAM, but it is reported
that on some systems device drivers allocate substantial
amounts of memory during suspend and the creation of the image
fails as a result (too little memory is preallocated).

Modify the autotuning mechanism to use 1/3 instead of 2/5 of RAM
as the default image size, which is reported to be sufficient for
the affected systems.

40dc166cb5 PM / Core: Introduce struct syscore_ops for core subsystems PM
Some subsystems need to carry out suspend/resume and shutdown
operations with one CPU on-line and interrupts disabled.  The only
way to register such operations is to define a sysdev class and
a sysdev specifically for this purpose which is cumbersome and
inefficient.  Moreover, the arguments taken by sysdev suspend,
resume and shutdown callbacks are practically never necessary.

For this reason, introduce a simpler interface allowing subsystems
to register operations to be executed very late during system suspend
and shutdown and very early during resume in the form of
strcut syscore_ops objects.

f9b9e806ae PM QoS: Make pm_qos settings readable

While in this case it was a driver bug (ath9k):
https://bugzilla.kernel.org/show_bug.cgi?id=27532

powertop or others may want to read out cpu_dma_latency
restrictions which could be the cause of preventing a machine
entering deeper C-states.

Output with this patch:

7ae4961878 PM / OPP: opp_find_freq_exact() documentation fix
opp_find_freq_exact() documentation has is_available instead
of available. This also fixes warning with the kernel-doc:
scripts/kernel-doc drivers/base/power/opp.c >/dev/null
Warning(drivers/base/power/opp.c:246): No description found for parameter 'available'
Warning(drivers/base/power/opp.c:246): Excess function parameter 'is_available' description in 'opp_find_freq_exact'
