During the initial porting process to 4.19, RmNet's tracepoints were moved
to the pre-existing trace/events/rmnet.h file. However, for backward
compatibility with older targets, they need to be moved back to the
original location. This has the added benefit of reducing the clutter
in the trace/events directory.

Refaults happen during transitions between workingsets as well as in-place
thrashing. Knowing the difference between the two has a range of
applications, including measuring the impact of memory shortage on the
system performance, as well as the ability to smarter balance pressure
between the filesystem cache and the swap-backed workingset.
During workingset transitions, inactive cache refaults and pushes out
established active cache. When that active cache isn't stale, however,
and also ends up refaulting, that's bonafide thrashing.
Introduce a new page flag that tells on eviction whether the page has been
active or not in its lifetime. This bit is then stored in the shadow
entry, to classify refaults as transitioning or thrashing.
How many page->flags does this leave us with on 32-bit?
20 bits are always page flags
21 if you have an MMU
23 with the zone bits for DMA, Normal, HighMem, Movable
29 with the sparsemem section bits
30 if PAE is enabled
31 with this patch.
So on 32-bit PAE, that leaves 1 bit for distinguishing two NUMA nodes. If
that's not enough, the system can switch to discontigmem and re-gain the 6
or 7 sparsemem section bits.

As deadline tasks doesn't have priority, their priority is set
to -1. If there are any deadline tasks in the system, chrome/tracing
doesn't show results as expected as it can't recognize tasks with
priority -1. Fix it by using 150 as priority for deadline tasks.

When copying the SCM call arugment buffer for trace events,
the amount of bytes specified to copy is MAX_SCM_ARGS, which
is not correct, as this is only the maximum number of SCM
call arguments, but each argument is 8 bytes, and thus the
amount of bytes that should be copied is actually 80 bytes.
Since the size of the SCM call argument buffer is a compile
time constant, use sizeof() on the argument buffer to compute
the amount of bytes that should be copied.

The current code starts the CPU search with max capacity cluster
for schedtune boosted tasks. If any of the CPU in this cluster
can accommodate the task without exceeding its original capacity,
the search is not extended to other clusters. This approach results
in sub-optimal performance on tri-cluster systems with 1 CPU in the
max capacity cluster. The max capacity CPU is packed with several
tasks while the other mid capacity CPUs are idle. Fix this issue by
starting the CPU search with mid capacity cluster as long as the
task fits. The search is also expanded to the max capacity cluster
and the best CPU is selected among the iterated CPUs. The best CPU
is either an idle CPU in the shallowest c-state or CPU with maximum
spare capacity when all the iterated CPUs are busy. The energy
evaluation is also skipped for boosted tasks to maximize the
performance.
While at it, extend the sched_task_util trace point to print if
the task is schedtune boosted or not.

Some workloads doing memory access might appear memory latency bound even
though they might not actually be memory latency bound.
This error can happen when the core that's running the workload is very
parallelized or can do out of order executions, etc so not all memory
accesses would actually stall the core.
This can also happen when the the memory access monitoring capabilities
aren't ideal and end up counting more kinds of memory accesses than what
would be ideal. In this case, the IPM ratio can be lower than what it would
be if we had ideal monitoring capabilities.
To account for these errors, if the core has a stall cycle counting
capabilities, check for a minimum stall% before the workload is considered
memory latency bound. This would help reduce the inaccuracies, but is not a
replacement for IPM ratio scheme because the stall% method doesn't allow us
to detect which level of memory the workload is latency bound on, but the
IPM ratio does (based on which memory accesses we use for calculating the
ratio).

The CPUBW HW monitor devfreq governor uses the Krait L2 PM counters to
determine the bandwidth needed by the Krait CPU subsystem. This governor
can be used in conjunction with the CPUBW devfreq device to dynamically
scale the DDR frequency based on the demand/actual usage from the Krait CPU
subsystem. Since this governor uses the Krait L2 PM counters it can
conflict with certain profiling tools.
The Krait L2 performance monitor counters have the capability to count the
no. of read/write transactions going out the master ports. They also have
the capability to raise interrupts when they overflow. This driver uses
those counters to determine the true usage of DDR from the Krait processor
subsystem and then recommends CPU DDR BW votes based on the measured values
and the following tunable parameters.
The driver provides various tunables that allow it to be tuned more in
favor of power or performance:
- io_percent: The percentage of the CPU time that can be spent waiting on
memory I/O. Lower value is better performance and worse power.
- sample_ms: The sampling period in milliseconds. This only affects the
sampling period when DDR use is ramping down or is increasing very slowly
(See tolerance_percent).
- tolerance_percent: The minimum increase in DDR use, compared to previous
sample, that will trigger an IRQ to immediately bump up the bandwidth
vote. It's expressed as a percentage of the previous sampled DDR use.
- decay_rate: The parameter controls the rate at which the history is
forgotten when ramping down. This is expressed as a percentage of history
to be forgotten. So 100% means ignore history, 0% mean never forget the
historical max. The default 90% means forget 90% of history each time.
- guard_band_mbps: This is a margin that's added to the measured BW (and
hence also the Bus BW votes) that's present to account for the time it
takes to ramp up the DDR BW while the CPU continues to use the DDR.
- bw_step: All BW votes are rounded up to multiples of bw_step. The default
value is 200 MB/s that turns out to ~25 or 12.5 MHz based on the SoC. A
smaller value would mean more frequent bus BW changes. A higher value
would mean less frequent BW vote updates, but also means at times an
unnecessarily higher BW vote (due to the rounding up).

commit d4b09acf924b84bae77cad090a9d108e70b43643 upstream.
if node have NFSv41+ mounts inside several net namespaces
it can lead to use-after-free in svc_process_common()
svc_process_common()
/* Setup reply header */
rqstp->rq_xprt->xpt_ops->xpo_prep_reply_hdr(rqstp); <<< HERE
svc_process_common() can use incorrect rqstp->rq_xprt,
its caller function bc_svc_process() takes it from serv->sv_bc_xprt.
The problem is that serv is global structure but sv_bc_xprt
is assigned per-netnamespace.
According to Trond, the whole "let's set up rqstp->rq_xprt
for the back channel" is nothing but a giant hack in order
to work around the fact that svc_process_common() uses it
to find the xpt_ops, and perform a couple of (meaningless
for the back channel) tests of xpt_flags.
All we really need in svc_process_common() is to be able to run
rqstp->rq_xprt->xpt_ops->xpo_prep_reply_hdr()
Bruce J Fields points that this xpo_prep_reply_hdr() call
is an awfully roundabout way just to do "svc_putnl(resv, 0);"
in the tcp case.
This patch does not initialiuze rqstp->rq_xprt in bc_svc_process(),
now it calls svc_process_common() with rqstp->rq_xprt = NULL.
To adjust reply header svc_process_common() just check
rqstp->rq_prot and calls svc_tcp_prep_reply_hdr() for tcp case.
To handle rqstp->rq_xprt = NULL case in functions called from
svc_process_common() patch intruduces net namespace pointer
svc_rqst->rq_bc_net and adjust SVC_NET() definition.
Some other function was also adopted to properly handle described case.
