A recent change to the ioctl handling caused a new harmless
warning in the NVMe driver on all 32-bit machines:
drivers/block/nvme-core.c: In function 'nvme_submit_io':
drivers/block/nvme-core.c:1794:29: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
In order to shup up that warning, this introduces a new
temporary variable that uses a double cast to extract
the pointer from an __u64 structure member.

It was inconvenient that perf cannot be quit with SIGINT during
processing samples on TUI especially for large data files.
This was because the first argument of SLang_init_tty(), abort_char,
being 0. The manual says it's the ascii value of the control character
that will be used to generate the interrupt signal [1]. Passing -1
means to use the default value (Ctrl-C).
However, after processing samples, Ctrl-C was used to in other cases as
well - like stepping back from annotate. So recover the original
behavior after processing.

To make it consistent with the other dso lifetime routines.
For instance:
struct dso *vdso__new(struct machine *machine, const char *short_name,
const char *long_name)
Becomes:
struct dso *machine__addnew_vdso(struct machine *machine, const
char *short_name, const char *long_name)
Because:
1) There is no 'struct vdso' for us to have vdso__ prefixed routines.
2) Because it will not really just create a new instance of 'struct
dso', it'll call dso__new() but it will also insert it into the
DSO's list/rbtree, and we have a method name for that: 'addnew',
just like we have dsos__addnew().
3) So it is really a 'struct machine' operation, it is the first
argument, etc.
This way the place where this is used gets consistent:
if (vdso) {
pgoff = 0;
- dso = vdso__dso_findnew(machine, thread);
+ dso = machine__findnew_vdso(machine, thread);
} else
dso = machine__findnew_dso(machine, filename);

The warning was added by commit aa6df8d ("dm: fix free_rq_clone() NULL

clone->q == NULL is valid usage for the case where
dm_kill_unmapped_request() initiates request cleanup.

NFSv2 can set the atime and/or mtime of a file to specific timestamps but not
to the server's current time. To implement the equivalent of utimes("file",
NULL), it uses a heuristic.
NFSv3 and later do support setting the atime and/or mtime to the server's
current time directly. The NFSv2 heuristic is still enabled, and causes
timestamps to be set wrong sometimes.
Fix this by moving the heuristic into the NFSv2 specific code. We can leave it
out of the create code path: the owner can always set timestamps arbitrarily,
and the workaround would never trigger.

Each CCI model have different event/source codes and formats. This
patch exports this information via the sysfs, which includes the
aliases for the events. The aliases are listed by 'perf list', helping
the users to specify the name of the event instead of the binary
config values.
Each event alias must accompany the 'source' code except for the
following cases :
1) CCI-400 - cycles event, doesn't relate to an interface.
2) CCI-500 - Global events to the CCI. (Fixed source code = 0xf)
Each CCI model provides two sets of attributes(format and event),
which are dynamically populated before registering the PMU, to
allow for the appropriate information.

CCI-500 provides 8 event counters which can count any of the
supported events independently. The PMU event id is a 9-bit
value made of two parts.
bits [8:5] - Source port
0x0-0x6 Slave Ports
0x8-0xD Master Ports
0xf Global Events to CCI
0x7,0xe Reserved
bits [0:4] - Event code (specific to each type of port)
The generic CCI-500 controlling interface remains the same with CCI-400.
However there are some differences in the PMU event counters.
- No cycle counter
- Upto 8 counters(4 in CCI-400)
- Each counter area is 64K(4K in CCI400)
- The counter0 starts at offset 0x10000 from the base of CCI

Given that each CCI has different set of interfaces and
its associated events, it is good to abstract the validation of the
event codes to make it easier to add support for a new CCI model.
This patch also abstracts the mapping of a given event to a counter,
as there are some special counters for certain specific events.
We assume that the fixed hardware counters are always at the beginning,
so that we can use cci_model->fixed_hw_events as an upper bound to given
idx to check if we need to program the counter for an event.

Adds the PMU model specific counters to the PMU model
abstraction to make it easier to add a new PMU.
The patch cleans up the naming convention used all over
the code.
e.g, CCI_PMU_MAX_HW_EVENTS => maximum number of events that
can be counted at any time, which is in fact the maximum
number of counters available.
Change all such namings to use 'counters' instead of events.
This patch also abstracts the following:
1) Size of a PMU event counter area.
2) Maximum number of programmable counters supported by the PMU model
3) Number of counters which counts fixed events (e.g, cycle
counter on CCI-400).
Also changes some of the static allocation of the data
structures to dynamic, to accommodate the number of events
supported by a PMU.
Gets rid ofthe CCI_PMU_* defines for the model. All such
data should be accessed via the model abstraction.
Limits the number of counters to the maximum supported
by the 'model'.

In some cases some channel survey data was
reported incorrect.
Channel info events were expected to come in pairs
without and with COMPLETE flag set respectively
for each channel visit during scan.
The known deviation from this is rule for last
scan chan info and first (next) scan chan info
both have COMPLETE flag set. This was either
programmed with the intent of providing BSS cycle
count info or this is an artefact of firmware scan
state machine. Either way this is useless due to
short wraparound time, wraparound quirks and no
overflow notification.
Survey dumps now include only data gathered during
scan channel visits that can be computed
correctly.

When QCA988X cycle counter HW register wraps
around it resets to 0x7fffffff instead of 0. All
other cycle counter related registers are divided
by 2 so they never wraparound themselves. QCA61X4
has a uniform CC and it wraparounds in a regular
fashion though.
Worst case wraparound time is approx 24 seconds
(2**31 / 88MHz). Since scan channel visit times
are max 5 seconds (offchannel case) it is
guaranteed there's been at most 1 wraparound and
it is possible to compute survey active time
value. It is, however, impossible to determine the
point at which Rx Clear Count has been divided by
two so it is not reported upon wraparound.
This fixes some occasional incorrect survey data
on QCA988X as some channels (depending on how/when
scan/offchannel requests were requested) would
have approx 24 sec active time which wasn't
actually the case.
This should improve hostapd ACS a little bit.
