For the ondemand and conservative governors (generally, governors
that use the common code in cpufreq_governor.c), there are two static
data structures representing the governor, the struct governor
structure (the interface to the cpufreq core) and the struct
common_dbs_data one (the interface to the cpufreq_governor.c code).
There's no fundamental reason why those two structures have to be
separate. Moreover, if the struct governor one is included into
struct common_dbs_data, it will be possible to reach the latter from
the policy via its policy->governor pointer, so it won't be necessary
to pass a separate pointer to it around. For this reason, embed
struct governor in struct common_dbs_data.

Do not pass struct dbs_data pointers to the family of functions
implementing governor operations in cpufreq_governor.c as they can
take that pointer from policy->governor by themselves.
The cpufreq_governor_init() case is slightly more complicated, since
policy->governor may be NULL when it is invoked, but then it can reach
the pointer in question via its cdata argument just fine.
While at it, rework cpufreq_governor_dbs() to avoid a pointless
policy_governor check in the CPUFREQ_GOV_POLICY_INIT case.

Every governor relying on the common code in cpufreq_governor.c
has to provide its own mutex in struct common_dbs_data. However,
there actually is no need to have a separate mutex per governor
for this purpose, they may be using the same global mutex just
fine. Accordingly, introduce a single common mutex for that and
drop the mutex field from struct common_dbs_data.
That at least will ensure that the mutex is always present and
initialized regardless of what the particular governors do.
Another benefit is that the common code does not need a pointer to
a governor-related structure to get to the mutex which sometimes
helps.
Finally, it makes the code generally easier to follow.

Instead of using a per-CPU deferrable timer for queuing up governor
work items, register a utilization update callback that will be
invoked from the scheduler on utilization changes.
The sampling rate is still the same as what was used for the
deferrable timers and the added irq_work overhead should be offset by
the eliminated timers overhead, so in theory the functional impact of
this patch should not be significant.

Introduce a mechanism by which parts of the cpufreq subsystem
("setpolicy" drivers or the core) can register callbacks to be
executed from cpufreq_update_util() which is invoked by the
scheduler's update_load_avg() on CPU utilization changes.
This allows the "setpolicy" drivers to dispense with their timers
and do all of the computations they need and frequency/voltage
adjustments in the update_load_avg() code path, among other things.
The update_load_avg() changes were suggested by Peter Zijlstra.

Remove the union in evsel so that the database id and priv pointer can
be used simultainously without conflicting and crashing.
Detailed Description for the fixed bug follows:
perf script crashes with a segmentation fault on user space tool version
4.5.rc7.ge2857b when using the python database export API. It works
properly in 4.4 and prior versions.
the crash fist appeared in:
cfc8874a4859 ("perf script: Process cpu/threads maps")
How to reproduce the bug:
Remove any temporary files left over from a previous crash (if you have
already attemped to reproduce the bug):
$ rm -r test_db-perf-data
$ dropdb test_db
$ perf record timeout 1 yes >/dev/null
$ perf script -s scripts/python/export-to-postgresql.py test_db

It is now equal to use_eager_fpu(), which simply tests a cpufeature bit.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

When eager FPU is disabled, KVM will still see the MPX bit in CPUID and
presumably the MPX vmentry and vmexit controls. However, it will not
be able to expose the MPX XSAVE features to the guest, because the guest's
accessible XSAVE features are always a subset of host_xcr0.
In this case, we should disable the MPX CPUID bit, the BNDCFGS MSR,
and the MPX vmentry and vmexit controls for nested virtualization.
It is then unnecessary to enable guest eager FPU if the guest has the
MPX CPUID bit set.

After fixing FPU option parsing, we now parse the 'no387' boot option
too early: no387 clears X86_FEATURE_FPU before it's even probed, so
the boot CPU promptly re-enables it.
I suspect it gets even more confused on SMP.
Fix the probing code to leave X86_FEATURE_FPU off if it's been
disabled by setup_clear_cpu_cap().

When growing halt-polling, there is no check that the poll time exceeds
the limit. It's possible for vcpu->halt_poll_ns grow once past
halt_poll_ns, and stay there until a halt which takes longer than
vcpu->halt_poll_ns. For example, booting a Linux guest with
halt_poll_ns=11000:
... kvm:kvm_halt_poll_ns: vcpu 0: halt_poll_ns 0 (shrink 10000)
... kvm:kvm_halt_poll_ns: vcpu 0: halt_poll_ns 10000 (grow 0)

In the Amlogic Meson8 / Meson8b platforms we have two different buses:
cbus and aobus, corresponding to 2 different power domains (regular and
always-on). On each bus a different set of registers is mapped to manage
muxes, GPIOs and in general to control a clear subset of the pins.
Considering this architecture, having two different pinctrl devices, one
for each bus / power domain, makes much more sense than just having one
single device.
Right now we have one single pin controller driver that uses two
different domains (represented by 'gpio' and 'gpio-ao' sub-nodes in the
DTS) to manage the set of registers on the two buses. This dual-domain
configuration is hardcoded into the driver that strictly requires one
domain for each bus in the same pin controller device.
With this patch we refactor the driver to allow splitting the driver in
two parts. This change is needed to have a proper description of the HW
in the device-tree where we want to introduce aobus and cbus.

Just like on GICv2, we're a bit hammer-happy with GICv3, and access
them more often than we should.
Adopt a policy similar to what we do for GICv2, only save/restoring
the minimal set of registers. As we don't access the registers
linearly anymore (we may skip some), the convoluted accessors become
slightly simpler, and we can drop the ugly indexing macro that
tended to confuse the reviewers.

GICv2 registers are *slow*. As in "terrifyingly slow". Which is bad.
But we're equaly bad, as we make a point in accessing them even if
we don't have any interrupt in flight.
A good solution is to first find out if we have anything useful to
write into the GIC, and if we don't, to simply not do it. This
involves tracking which LRs actually have something valid there.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

The Kconfig / Makefile currently controlling compilation of this code is:
drivers/pinctrl/sh-pfc/Makefile:obj-$(CONFIG_PINCTRL_SH_PFC) += sh-pfc.o
drivers/pinctrl/sh-pfc/Makefile:sh-pfc-objs = core.o pinctrl.o
drivers/pinctrl/sh-pfc/Kconfig:config PINCTRL_SH_PFC
drivers/pinctrl/sh-pfc/Kconfig: def_bool y
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init already wasn't being used in this code, the init
ordering remains unchanged with this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/Kconfig:config PINCTRL_MESON
drivers/pinctrl/Kconfig: bool
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
We don't replace module.h with init.h since the file already has that.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

The Kconfig for this driver is currently:
config PINCTRL_MT6397
bool "Mediatek MT6397 pin control" if COMPILE_TEST && !MFD_MT6397
...meaning that it is currently not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
