There are no active clients of the legacy API and we now also have a
better way to handle genpd DT support. So let's remove the legacy API.

While a PM domain can enable PM runtime management of its devices' module
clocks by setting
genpd->dev_ops.stop = pm_clk_suspend;
genpd->dev_ops.start = pm_clk_resume;
this also requires registering the clocks with the pm_clk subsystem.
In the legacy case, this is handled by the platform code, after
attaching the device to its PM domain.
When the devices are instantiated from DT, devices are attached to their
PM domains by generic code, leaving no method for the platform-specific
PM domain code to register their clocks.
Add two callbacks, allowing a PM domain to perform platform-specific
tasks when a device is attached to or detached from a PM domain.

So that we don't continue polling on vanished file descriptors, i.e.
file descriptors for events monitoring threads that exited.
I.e. the following 'trace' command now exits as expected, instead
of staying in an eternal loop:
$ sleep 5s &
$ trace -p `pidof sleep`

As noticed by receiving a POLLHUP for all its pollfd entries.
That will remove the refcount taken in perf_evlist__mmap_per_evsel(),
and when all events are consumed via perf_evlist__mmap_read() +
perf_evlist__mmap_consume(), the ring buffer will be unmap'ed.
Thanks to Jiri Olsa for pointing out that we must wait till all events
are consumed, not being ok to unmmap just when receiving all the
POLLHUPs.

We will use this in perf's evlist class so that it can, at
fdarray__filter() time, to unmap the associated ring buffer.
We may need to have further info associated with each fdarray entry, in
that case we'll make that int array a 'union fdarray_priv' one and put a
pointer there so that users can stash whatever they want there. For now,
an int is enough tho.
v2: Add clarification to the per array entry priv area, as well as make
it a union, which makes usage a bit longer, but if/when we make it
use more space by allowing per entry pointers existing users source
code will not have to be changed, just rebuilt.

We need to know how many fds are using a perf mmap via
PERF_EVENT_IOC_SET_OUTPUT, so that we can know when to ditch an mmap,
refcount it.
v2: Automatically unmap it when the refcount hits one, which will happen
when all fds are filtered by perf_evlist__filter_pollfd(), in later
patches.

The extensible file description array that grew in the perf_evlist class
can be useful for other tools, as it is not something that only evlists
need, so move it to tools/lib/api/fd to ease sharing it.
v2: Don't use {} like in:
libapi_dirs:
$(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/
in Makefiles, as it will not work in some systems, as in ubuntu13.10.
v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa)
v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to
be checked if it is really needed there, but has no place in the
fdarray class (Fix from Jiri Olsa)
v5: Remove evlist details from fdarray grow/filter tests. Improve it a
bit doing more tests about expected internal state.

autogrow, no need to copy all events to a local pollfd array, just add

This way we will be able to add more file descriptors to be polled,
like stdin or some timer fd.
At this point we might as well yank the pollfd class from evlist so that
it can be used in other places.

Because we want to notice when they get POLLHUP'ed, so that we can
figure out when all threads exited in a workload being monitored.
We can't just monitor the fds that were mmaped, we need to notice when
all the fds that were PERF_EVENT_IOC_SET_OUTPUT'ed too, because the mmap
stays even after the fd that originally was used to do the mmap call
went away, its only when all the set-output fds for a mmap are gone that
the mmap is.

We want to know when the fd went away, like when a monitored thread
exits.
If we do not monitor such events, then the tools will wait forever on
events from a vanished thread, like when running:
$ sleep 5s &
$ perf record -p `pidof sleep`
This builds upon the kernel patch by Jiri Olsa that actually makes a
poll on those file descriptors to return POLLHUP.
It is also needed to change the tools to use
perf_evlist__filter_pollfd() to check if there are remainings fds to
monitor or if all are gone, in which case they will exit the
poll/mmap/read loop.

To remove all entries in evlist->pollfd[] that have revents matching at
least one of the bits in the specified mask.
It'll adjust evlist->nr_fds to the number of unfiltered fds and will
return this value, as a convenience and to avoid requiring direct access
to internal state of perf_evlist objects.
This will be used after polling the evlist fds so that we remove fds
that were closed by the kernel.

The sgi values calculated in read_set_clear_sgi_pend_reg() and
write_set_clear_sgi_pend_reg() were horribly incorrectly multiplied by 4
with catastrophic results in that subfunctions ended up overwriting

This showed up as bugs in kfree() and the kernel complaining a lot of

IO domain voltages on some Rockchip SoCs are variable but need to be
kept in sync between the regulators and the SoC using a special
register.
A specific example using rk3288:
- If the regulator hooked up to a pin like SDMMC0_VDD is 3.3V then
bit 7 of GRF_IO_VSEL needs to be 0. If the regulator hooked up to
that same pin is 1.8V then bit 7 of GRF_IO_VSEL needs to be 1.
Said another way, this driver simply handles keeping bits in the SoC's
general register file (GRF) in sync with the actual value of a voltage
hooked up to the pins.
Note that this driver specifically doesn't include:
- any logic for deciding what voltage we should set regulators to
- any logic for deciding whether regulators (or internal SoC blocks)
should have power or not have power
If there were some other software that had the smarts of making
decisions about regulators, it would work in conjunction with this
driver. When that other software adjusted a regulator's voltage then
this driver would handle telling the SoC about it. A good example is
vqmmc for SD. In that case the dw_mmc driver simply is told about a
regulator. It changes the regulator between 3.3V and 1.8V at the
right time. This driver notices the change and makes sure that the
SoC is on the same page.

Pull "ARM: tegra: device tree changes for 3.18" from Stephen Warren:
The main highlights are:
* SATA and PCIe support added to Tegra124, and enabled on Jetson TK1.
* Touchpad enabled on Venice2 (although the driver still has a few issues
to be worked out).
* NVIDIA reference boards rely on the bootloader to program the pinmux.
* Support added for the Acer Chromebook 13 (CB5).
* DT nodes added for the Tegra flow controller HW module. This will
help reduce use of iomap.h in a future code cleanup.

Pull "ARM: tegra: core SoC code changes for 3.18" from Stephen Warren:
the primary change here gets its address information from DT rather than
iomap.h. This removes one more user of iomap.h, and will help allow the
code to move to a location that can be shared between arch/arm and
arch/arm64.
An unused header file was also removed.

In PCIe r1.0, sec 5.10.2, bit 0 of the Uncorrectable Error Status, Mask,
and Severity Registers was for "Training Error." In PCIe r1.1, sec 7.10.2,
bit 0 was redefined to be "Undefined."
Rename PCI_ERR_UNC_TRAIN to PCI_ERR_UNC_UND to reflect this change.
No functional change.
