Pull f2fs updates from Jaegeuk Kim:
"In this round, we introduce sysfile-based quota support which is
required for Android by default. In addition, we allow that users are
able to reserve some blocks in runtime to mitigate performance drops
in low free space.
Enhancements:
- assign proper data segments according to write_hints given by user
- issue cache_flush on dirty devices only among multiple devices
- exploit cp_error flag and add more faults to enhance fault
injection test
- conduct more readaheads during f2fs_readdir
- add a range for discard commands
Bug fixes:
- fix zero stat->st_blocks when inline_data is set
- drop crypto key and free stale memory pointer while evict_inode is
failing
- fix some corner cases in free space and segment management
- fix wrong last_disk_size
This series includes lots of clean-ups and code enhancement in terms
of xattr operations, discard/flush command control. In addition, it
adds versatile debugfs entries to monitor f2fs status"

It is preferable that WALT window rollover occurs just
before a tick, since the tick is an opportune moment
to record a complete window's statistics, as well as report
those stats to the cpu frequency governor. When CONFIG_HZ
results in a TICK_NSEC that isn't a integral number, this
requirement may be violated. Account for this by reducing
the WALT window size to the nearest multiple of TICK_NSEC.
Commit d368c6faa1 ("sched: walt: fix window misalignment
when HZ=300") attempted to do this but WALT isn't using
MIN_SCHED_RAVG_WINDOW as the window size and the patch was
doing nothing.
Also, change the type of 'walt_disabled' to bool and warn
if an invalid window size causes WALT to be disabled.

Preempt and irq trace events can be used for tracing the start and
end of an atomic section which can be used by a trace viewer like
systrace to graphically view the start and end of an atomic section and
correlate them with latencies and scheduling issues.
This also serves as a prelude to using synthetic events or probes to
rewrite the preempt and irqsoff tracers, along with numerous benefits of
using trace events features for these events.

With the ability to choose between WALT and PELT for utilisation tracking
we can have the situation where we're using WALT to make all the
decisions and reporting PELT figures in the sched_load_avg_(cpu|task)
trace points. This is not too much of an issue, but when analysing trace
it is nice to see numbers representing what the scheduler is using rather
than needing to add in additional sched_walt_* traces to figure it out.
Add reporting for both types, and make the util_avg member reflect what
will be seen from cpu or task_util functions in the scheduler.

commit bf7165cfa23695c51998231c4efa080fe1d3548d upstream.
There are several trace include files that define TRACE_INCLUDE_FILE.
Include several of them in the same .c file (as I currently have in
some code I am working on), and the compile will blow up with a
"warning: "TRACE_INCLUDE_FILE" redefined #define TRACE_INCLUDE_FILE syscalls"
Every other include file in include/trace/events/ avoids that issue
by having a #undef TRACE_INCLUDE_FILE before the #define; syscalls.h
should have one, too.

Contains also:
eas/stune: schedtune cpu boost_max must be non-negative.
This is to avoid under-accounting cpu capacity which may
cause task stacking and frequency spikes.

Currently the build for a single-core (e.g. user-mode) Linux is broken
and this configuration is required (at least) to run some network tests.
The main issues for the current code support on single-core systems are:
1. {se,rq}::sched_avg is not available nor maintained for !SMP systems
This means that load and utilisation signals are NOT available in single
core systems. All the EAS code depends on these signals.
2. sched_group_energy is also SMP dependant. Again this means that all the
EAS setup and preparation code (energyn model initialization) has to be
properly guarded/disabled for !SMP systems.
3. SchedFreq depends on utilization signal, which is not available on
!SMP systems.
4. SchedTune is useless on unicore systems if SchedFreq is not available.
5. WALT machinery is not required on single-core systems.
This patch addresses all these issues by enforcing some constraints for
single-core systems:
a) WALT, SchedTune and SchedTune are now dependant on SMP
b) The default governor for !SMP systems is INTERACTIVE
c) The energy model initialisation/build functions are
d) Other minor code re-arrangements and CONFIG_SMP guarding to enable
single core builds.

Adds a new trace event to be called from clk_set_parent. Some
cpufreq drivers, including Tegra, reparent the cpu clock to a
slower clock while the main pll is relocking, tracing
clk_set_parent allows traces to show how for long the cpu is
running slower.
Uses a separate TRACE_EVENT instead of the clock event class to
allow the event to contain string names for the child and the
parent.

Add ftrace event trace_sched_cpu_hotplug to track cpu
hot-add and hot-remove events.
This is useful in a variety of power, performance and
debug analysis scenarios.
