cpufreq: cpufreq-cpu0: remove dependency on THERMAL and REGULATOR
cpufreq-cpu0 uses thermal framework to register a cooling device, but doesn't
depend on it as there are dummy calls provided by thermal layer when
CONFIG_THERMAL=n. And when these calls fail, the driver is still usable.
Similar explanation is valid for regulators as well. We do have dummy calls
available for regulator APIs and the driver can work even when those calls
fail.
So, we don't really need to mention thermal and regulators as a dependency for
cpufreq-cpu0 in Kconfig as platforms without support for thermal/regulator can
also use this driver. Remove this dependency.

cpufreq: governor: remove copy_prev_load from 'struct cpu_dbs_common_info'
'copy_prev_load' was recently added by commit:
18b46ab (cpufreq: governor: Be
friendly towards latency-sensitive bursty workloads).
It actually is a bit redundant as we also have 'prev_load' which can store any
integer value and can be used instead of 'copy_prev_load' by setting it zero.
True load can also turn out to be zero during long idle intervals (and hence the
actual value of 'prev_load' and the overloaded value can clash). However this is
not a problem because, if the true load was really zero in the previous
interval, it makes sense to evaluate the load afresh for the current interval
rather than copying the previous load.
So, drop 'copy_prev_load' and use 'prev_load' instead.
Update comments as well to make it more clear.

cpufreq: governor: Be friendly towards latency-sensitive bursty workloads
Cpufreq governors like the ondemand governor calculate the load on the CPU
periodically by employing deferrable timers. A deferrable timer won't fire
if the CPU is completely idle (and there are no other timers to be run), in
order to avoid unnecessary wakeups and thus save CPU power.
However, the load calculation logic is agnostic to all this, and this can
lead to the problem described below.
Time (ms) CPU 1
100 Task-A running
110 Governor's timer fires, finds load as 100% in the last
10ms interval and increases the CPU frequency.
110.5 Task-A running
120 Governor's timer fires, finds load as 100% in the last
10ms interval and increases the CPU frequency.
125 Task-A went to sleep. With nothing else to do, CPU 1
went completely idle.
200 Task-A woke up and started running again.
200.5 Governor's deferred timer (which was originally programmed
to fire at time 130) fires now. It calculates load for the
time period 120 to 200.5, and finds the load is almost zero.
Hence it decreases the CPU frequency to the minimum.
210 Governor's timer fires, finds load as 100% in the last
10ms interval and increases the CPU frequency.
So, after the workload woke up and started running, the frequency was suddenly
dropped to absolute minimum, and after that, there was an unnecessary delay of
10ms (sampling period) to increase the CPU frequency back to a reasonable value.
And this pattern repeats for every wake-up-from-cpu-idle for that workload.
This can be quite undesirable for latency- or response-time sensitive bursty
workloads. So we need to fix the governor's logic to detect such wake-up-from-
cpu-idle scenarios and start the workload at a reasonably high CPU frequency.
One extreme solution would be to fake a load of 100% in such scenarios. But
that might lead to undesirable side-effects such as frequency spikes (which
might also need voltage changes) especially if the previous frequency happened
to be very low.
We just want to avoid the stupidity of dropping down the frequency to a minimum
and then enduring a needless (and long) delay before ramping it up back again.
So, let us simply carry forward the previous load - that is, let us just pretend
that the 'load' for the current time-window is the same as the load for the
previous window. That way, the frequency and voltage will continue to be set
to whatever values they were set at previously. This means that bursty workloads
will get a chance to influence the CPU frequency at which they wake up from
cpu-idle, based on their past execution history. Thus, they might be able to
avoid suffering from slow wakeups and long response-times.
However, we should take care not to over-do this. For example, such a "copy
previous load" logic will benefit cases like this: (where # represents busy
and . represents idle)
##########.........#########.........###########...........##########........
but it will be detrimental in cases like the one shown below, because it will
retain the high frequency (copied from the previous interval) even in a mostly
idle system:
##########.........#.................#.....................#...............
(i.e., the workload finished and the remaining tasks are such that their busy
periods are smaller than the sampling interval, which causes the timer to
always get deferred. So, this will make the copy-previous-load logic copy
the initial high load to subsequent idle periods over and over again, thus
keeping the frequency high unnecessarily).
So, we modify this copy-previous-load logic such that it is used only once
upon every wakeup-from-idle. Thus if we have 2 consecutive idle periods, the
previous load won't get blindly copied over; cpufreq will freshly evaluate the
load in the second idle interval, thus ensuring that the system comes back to
its normal state.
[ The right way to solve this whole problem is to teach the CPU frequency
governors to also track load on a per-task basis, not just a per-CPU basis,
and then use both the data sources intelligently to set the appropriate
frequency on the CPUs. But that involves redesigning the cpufreq subsystem,
so this patch should make the situation bearable until then. ]

sleeps injected). This ebizzy was run with a single-thread, tied to CPU 8.

Observation: Ebizzy went idle at 416.402202, and started running again at
416.502130. But cpufreq noticed the long idle period, and dropped the frequency
at 416.505739, only to increase it back again at 416.515742, realizing that the
workload is in-fact CPU bound. Thus ebizzy needlessly ran at the lowest frequency
for almost 13 milliseconds (almost 1 full sample period), and this pattern
repeats on every sleep-wakeup. This could hurt latency-sensitive workloads quite
a lot.

Observation: Ebizzy went idle at 465.035797, and started running again at
465.240178. Since ebizzy was the only real workload running on this CPU,
cpufreq retained the frequency at 4.1Ghz throughout the run of ebizzy, no
matter how many times ebizzy slept and woke-up in-between. Thus, ebizzy
got the 10ms worth of 4.1 Ghz benefit during every sleep-wakeup (as compared
to the run without the patch) and this boost gave a modest improvement in total
throughput, as shown below.
Sleeping-ebizzy records-per-second:
-----------------------------------
Utilization Without patch With patch Difference (Absolute and % values)
10% 274767 277046 + 2279 (+0.829%)
20% 543429 553484 + 10055 (+1.850%)

60%
1634908 1662018 + 27110 (+1.658%)
A rudimentary and somewhat approximately latency-sensitive workload such as
sleeping-ebizzy itself showed a consistent, noticeable performance improvement
with this patch. Hence, workloads that are truly latency-sensitive will benefit
quite a bit from this change. Moreover, this is an overall win-win since this
patch does not hurt power-savings at all (because, this patch does not reduce
the idle time or idle residency; and the high frequency of the CPU when it goes
to cpu-idle does not affect/hurt the power-savings of deep idle states).

cpufreq: add support for intermediate (stable) frequencies
Douglas Anderson, recently pointed out an interesting problem due to which
udelay() was expiring earlier than it should.
While transitioning between frequencies few platforms may temporarily switch to
a stable frequency, waiting for the main PLL to stabilize.
For example: When we transition between very low frequencies on exynos, like
between 200MHz and 300MHz, we may temporarily switch to a PLL running at 800MHz.
No CPUFREQ notification is sent for that. That means there's a period of time
when we're running at 800MHz but loops_per_jiffy is calibrated at between 200MHz
and 300MHz. And so udelay behaves badly.
To get this fixed in a generic way, introduce another set of callbacks
get_intermediate() and target_intermediate(), only for drivers with
target_index() and CPUFREQ_ASYNC_NOTIFICATION unset.
get_intermediate() should return a stable intermediate frequency platform wants
to switch to, and target_intermediate() should set CPU to that frequency,
before jumping to the frequency corresponding to 'index'. Core will take care of
sending notifications and driver doesn't have to handle them in
target_intermediate() or target_index().
NOTE: ->target_index() should restore to policy->restore_freq in case of
failures as core would send notifications for that.

"ACPICA is the leader this time (63 commits), followed by cpufreq (28
commits), devfreq (15 commits), system suspend/hibernation (12
commits), ACPI video and ACPI device enumeration (10 commits each).
We have no major new features this time, but there are a few
significant changes of how things work. The most visible one will
probably be that we are now going to create platform devices rather
than PNP devices by default for ACPI device objects with _HID. That
was long overdue and will be really necessary to be able to use the
same drivers for the same hardware blocks on ACPI and DT-based systems
going forward. We're not expecting fallout from this one (as usual),
but it's something to watch nevertheless.
The second change having a chance to be visible is that ACPI video
will now default to using native backlight rather than the ACPI
backlight interface which should generally help systems with broken
Win8 BIOSes. We're hoping that all problems with the native backlight
handling that we had previously have been addressed and we are in a
good enough shape to flip the default, but this change should be easy
enough to revert if need be.
In addition to that, the system suspend core has a new mechanism to
allow runtime-suspended devices to stay suspended throughout system
suspend/resume transitions if some extra conditions are met
(generally, they are related to coordination within device hierarchy).
However, enabling this feature requires cooperation from the bus type
layer and for now it has only been implemented for the ACPI PM domain
(used by ACPI-enumerated platform devices mostly today).
Also, the acpidump utility that was previously shipped as a separate
tool will now be provided by the upstream ACPICA along with the rest
of ACPICA code, which will allow it to be more up to date and better
supported, and we have one new cpuidle driver (ARM clps711x).
The rest is improvements related to certain specific use cases,
cleanups and fixes all over the place.
Specifics:
- ACPICA update to upstream version
20140424. That includes a number
of fixes and improvements related to things like GPE handling,
table loading, headers, memory mapping and unmapping, DSDT/SSDT
overriding, and the Unload() operator. The acpidump utility from
upstream ACPICA is included too. From Bob Moore, Lv Zheng, David
Box, David Binderman, and Colin Ian King.
- Fixes and cleanups related to ACPI video and backlight interfaces
from Hans de Goede. That includes blacklist entries for some new
machines and using native backlight by default.
- ACPI device enumeration changes to create platform devices rather
than PNP devices for ACPI device objects with _HID by default. PNP
devices will still be created for the ACPI device object with
device IDs corresponding to real PNP devices, so that change should
not break things left and right, and we're expecting to see more
and more ACPI-enumerated platform devices in the future. From
Zhang Rui and Rafael J Wysocki.
- Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it
to handle system suspend/resume on Asus T100 correctly. From
Heikki Krogerus and Rafael J Wysocki.
- PM core update introducing a mechanism to allow runtime-suspended

- ARM changes are pretty small: support for the PSCI 0.2 hypercall

have a few emulator bugfixes and support for running nested
fully-virtualized Xen guests (para-virtualized Xen guests have
always worked). And some optimizations too.

Returning to what is here this time... we have 3 patches which fix
various warnings. Two are bug fixes (for quotas and also a rare
recovery race condition). The final patch, from Ben Marzinski, is an
important change in the freeze code which has been in progress for
some time. This removes the need to take and drop the transaction
lock for every single transaction, when the only time it was used, was
at file system freeze time. Ben's patch integrates the freeze
operation into the journal flush code as an alternative with lower

Pull first set of s390 updates from Martin Schwidefsky:
"The biggest change in this patchset is conversion from the bootmem
bitmaps to the memblock code. This conversion requires two common
code patches to introduce the 'physmem' memblock list.
We experimented with ticket spinlocks but in the end decided against
them as they perform poorly on virtualized systems. But the spinlock
cleanup and some small improvements are included.
The uaccess code got another optimization, the get_user/put_user calls
are now inline again for kernel compiles targeted at z10 or newer
machines. This makes the text segment shorter and the code gets a
little bit faster.
And as always some bug fixes"

After discussion at last year's KS (and some more on the mailing

"Now that the core bits are in, here's the pull request for the driver
related changes for 3.16. Nothing out of the ordinary here, mostly
business as usual. There are a few pulls of for-3.16/core into this
branch, which were done when the blk-mq was modified after the
mtip32xx conversion was put in.
The pull request contains:
- skd and cciss converted to use pci_enable_msix_exact(). From
Alexander Gordeev.
- A few mtip32xx fixes from Asai @ Micron.
- The conversion of mtip32xx from make_request_fn to blk-mq, and a
later small fix for that conversion on quiescing for non-queued IO.
From me.
- A fix for bsg to use an exported function to check whether this
driver is request based or not. Needed updating for blk-mq, which
is request based, but does not have a request_fn hook. From me.
- Small floppy bug fix from Jiri.
- A series of cleanups for the cdrom uniform layer from Joe Perches.
Gets rid of various old ugly macros, making the code conform more
to the modern coding style.
- A series of patches for drbd from the drbd crew (Lars Ellenberg and
Philipp Reisner).
- A use-after-free fix for null_blk from Ming Lei.
- Also from Ming Lei is a performance patch for virtio-blk, which can
net us a 3x win on kvm platforms where world notification is
expensive.
- Ming Lei also fixed a stall issue in virtio-blk, due to a race
between queue start/stop and resource limits.
- A small batch of fixes for xen-blk{back,front} from Olaf Hering and
Valentin Priescu"

Pull block core updates from Jens Axboe:
"It's a big(ish) round this time, lots of development effort has gone
into blk-mq in the last 3 months. Generally we're heading to where
3.16 will be a feature complete and performant blk-mq. scsi-mq is
progressing nicely and will hopefully be in 3.17. A nvme port is in
progress, and the Micron pci-e flash driver, mtip32xx, is converted
and will be sent in with the driver pull request for 3.16.
This pull request contains:
- Lots of prep and support patches for scsi-mq have been integrated.
All from Christoph.
- API and code cleanups for blk-mq from Christoph.
- Lots of good corner case and error handling cleanup fixes for
blk-mq from Ming Lei.
- A flew of blk-mq updates from me:
* Provide strict mappings so that the driver can rely on the CPU
to queue mapping. This enables optimizations in the driver.
* Provided a bitmap tagging instead of percpu_ida, which never
really worked well for blk-mq. percpu_ida relies on the fact
that we have a lot more tags available than we really need, it
fails miserably for cases where we exhaust (or are close to
exhausting) the tag space.
* Provide sane support for shared tag maps, as utilized by scsi-mq
* Various fixes for IO timeouts.
* API cleanups, and lots of perf tweaks and optimizations.
- Remove 'buffer' from struct request. This is ancient code, from
when requests were always virtually mapped. Kill it, to reclaim
some space in struct request. From me.
- Remove 'magic' from blk_plug. Since we store these on the stack
and since we've never caught any actual bugs with this, lets just
get rid of it. From me.
- Only call part_in_flight() once for IO completion, as includes two
atomic reads. Hopefully we'll get a better implementation soon, as
the part IO stats are now one of the more expensive parts of doing
IO on blk-mq. From me.
- File migration of block code from {mm,fs}/ to block/. This
includes bio.c, bio-integrity.c, bounce.c, and ioprio.c. From me,
from a discussion on lkml.
That should describe the meat of the pull request. Also has various
little fixes and cleanups from Dave Jones, Shaohua Li, Duan Jiong,
Fengguang Wu, Fabian Frederick, Randy Dunlap, Robert Elliott, and Sam
Bradshaw"
