Initialize ECC for Arria10 On-Chip RAM on machine startup. The OCRAM
memory must be initialized before data is stored in memory otherwise the
ECC will fail on reads. The previous check-in
2364d423a7b3 ("ARM: socfpga: Enable Arria10 OCRAM ECC on startup")
added the OCRAM enable and initialization code but was not called on
startup.

Add Skylake client support for RAPL domains. In addition to RAPL domains
in Broadwell clients, it has support for platform domain (aka PSys). The
PSys domain controls the entire SoC instead of just a CPU package. Unlike
package domain, PSys support requires more than just processor level
implementation. The other parts in the system need additional HW level
signaling, which OEMs need to support. When not supported, the energy
counter register in PSys domain returns 0.
Also corrected error in comment for GPU counter, which previously was
DRAM counter.

Add perf core PMU support for Intel Goldmont CPU cores:
- The init code is based on Silvermont.
- There is a new cache event list, based on the Silvermont cache event list.
- Goldmont has 32 LBR entries. It also uses new LBRv6 format, which
report the cycle information using upper 16-bit of the LBR_TO.
- It's recommended to use CPU_CLK_UNHALTED.CORE_P + NPEBS for precise cycles.
For details, please refer to the latest SDM058:

The following commit:
1fb3a8b2cfb2 ("xen/spinlock: Fix locking path engaging too soon under PVHVM.")
... moved the initalization of the kicker interrupt until after
native_cpu_up() is called.
However, when using qspinlocks, a CPU may try to kick another CPU that is
spinning (because it has not yet initialized its kicker interrupt), resulting
in the following crash during boot:

To fix this, only send the kick if the target CPU's interrupt has been
initialized. This check isn't racy, because the target is waiting for
the spinlock, so it won't have initialized the interrupt in the
meantime.

For the DRA7xx platform, add IP block data for the McASP, PWMSS,
and GPTimer12 IP blocks. Add lock and unlock functions for the
RTC IP blocks on the DRA7xx, AM33xx, and AM43xx devices. And add
a fix for the hwmod core for device driver unbind operations for
IP blocks with hardreset lines.
Basic build, boot, and PM test results are available here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.7/20160410132119/
Note that the testbed here does not have the DRA7xx board included yet.

This pull request brings in VC4 devicetree support and the other minor
DT changes for 4.7.
Also included is a DRM patch necessary to prevent regressions when
simplefb and vc4 drivers are both present. The patch was suggested by
the simplefb maintainer as the solution agreed upon at ELCE 2014, and
was acked by the DRM maintainer for merging through this tree.

Merge "omap fixes against v4.6-rc2" from Tony Lindgren
Fixes for omaps against v4.6-rc2, mostly to fix suspend for beagle-x15
that broke when we added runtime based SoC revision detection earlier.
It seems suspend worked earlier as things were only partially initialized,
while now we initialize things properly for dra7.
Note that the "ARM: OMAP: Catch callers of revision information prior
to it being populated" had to be reverted as it caused bogus warnings
for other SoCs because omap initcalls bail out based on revision being
set to 0 for other SoCs. These initcalls will mostly just disappear
when we drop support for omap3 legacy booting.
Also included is a fix for dra7 sys_32k_ck clock source that is not
enabled on boot making system fall back to using emulated clock.

- The asm helpers for calling into irq tracer were missing
- Add calls to above helpers in low level assembly entry code for ARCv2
- irq_save() uses CLRI to disable interrupts and returns the prev interrupt
state (in STATUS32) in a specific encoding (and not the raw value of
STATUS32). This is usable with SETI in irq_restore(). However
save_flags() reads the raw value of STATUS32 which doesn't pair with
irq_save/restore() and thus needs fixing.

As per hpa CE4100 platforms can also disable pnpbios:
http://lkml.kernel.org/r/5702B5C2.7070101@zytor.com
Then Sebastian also recently noted that CE4100 also disables
RTC probe, to do that Sebastian had long ago added the RTC
of_have_populated_dt() check, he noted that it was meant to
skip the RTC probe on all OF platforms but as of now, CE4100
was the only x86 DT using this.
We can just fold this requirement into the platform quirk
then. This now means that all of these match platform quirks
for pnpbios and RTC preferences:
* X86_SUBARCH_XEN
* X86_SUBARCH_LGUEST
* X86_SUBARCH_INTEL_MID
* X86_SUBARCH_CE4100

ACPI 5.2.9.3 IA-PC Boot Architecture flag ACPI_FADT_LEGACY_DEVICES
can be used to determine if a system has legacy devices LPC or
ISA devices. The x86 platform already has a struct which lists
known associated legacy devices, we start off careful only
by disabling root devices we should not regress with. The struct
and device list can be expanded with time to cover more root
legacy components.

Since we are removing paravirt_enabled() replace it with a
logical equivalent. Even though PNPBIOS is x86 specific we
add an arch-specific type call, which can be implemented by
any architecture to show how other legacy attribute devices
can later be also checked for with other ACPI legacy attribute
flags.
This implicates the first ACPI 5.2.9.3 IA-PC Boot Architecture
ACPI_FADT_LEGACY_DEVICES flag device, and shows how to add more.
The reason pnpbios gets a defined structure and as such uses
a different approach than the RTC legacy quirk is that ACPI
has a respective RTC flag, while pnpbios does not. We fold
the pnpbios quirk under ACPI_FADT_LEGACY_DEVICES ACPI flag
use case, and use a struct of possible devices to enable
future extensions of this.
As per 0-day, this bumps the vmlinux size using i386-tinyconfig as
follows:
TOTAL TEXT init.text x86_early_init_platform_quirks()
+32 +28 +28 +28
That's 4 byte overhead total, the rest is cleared out on init
as its all __init text.
v2: split out subarch handlng on switch to make it easier
later to add other subarchs. The 'fall-through' switch
handling can be confusing and we'll remove it later
when we add handling for X86_SUBARCH_CE4100.
v3: document vmlinux size impact as per 0-day, and also
explain why pnpbios is treated differently than the
RTC legacy feature.

The X86_BUG_F00F work around is responsible for fixing up the error
generated on attempted F00F exploitation from an OOPS to a SIGILL.
There is no reason why this code should not be allowed to run on
PV guest on a F00F-affected CPU -- it would simply never trigger.
The pv_enabled() check was there only to avoid printing the f00f
workaround, so removing the check is purely a cosmetic change.

There is already a check for boot_params.tboot_addr prior
to paravirt_enabled(). Both Xen and lguest, which are also the
only ones that set paravirt_enabled to true, never set the
boot_params.tboot_addr. The Xen folks are sure a force disable
to 0 is not needed, we recently forced disabled this on lguest.
With this in place this check is no longer needed.
Xen folks are sure force disable to 0 is not needed because
apm_info lives in .bss, we recently forced disabled this on
lguest, and on the Xen side just to be sure Boris zeroed out
the .bss for PV guests through commit 04b6b4a56884327c1648
("xen/x86: Zero out .bss for PV guests"). With this care taken
into consideration the paravirt_enabled() check is simply not
needed anymore.

There is already a check for apm_info.bios == 0, the
apm_info.bios is set from the boot_params.apm_bios_info.
Both Xen and lguest, which are also the only ones that set
paravirt_enabled to true, never set the apm_bios.info. The
Xen folks are sure force disable to 0 is not needed because
apm_info lives in .bss, we recently forced disabled this on
lguest, and on the Xen side just to be sure Boris zeroed out
the .bss for PV guests through commit 04b6b4a56884327c1648
("xen/x86: Zero out .bss for PV guests"). With this care taken
into consideration the paravirt_enabled() check is simply not
needed anymore.

This replaces the paravirt_enabled() check with a
proper x86 legacy platform quirk.
As per 0-day, this bumps the vmlinux size using i386-tinyconfig as
follows:
TOTAL TEXT init.text x86_early_init_platform_quirks()
+39 +35 +35 +25
That's a 4 byte total overhead, the rest is all cleared out
upon init as its all __init text.
v2: document 0-day vmlinux size impact

This moves the ACPI specific check into the ACPI boot code,
it also takes advantage of the x86_platform.legacy.rtc which
is checked for already on the RTC initialization code. This
lets us remove the nasty #ifdefery and consolidate the checks
to use only one toggle to disable the RTC init code.
The works as RTC is initialized by device_initcall(add_rtc_cmos),
this will run late in boot on start_kernel() during rest_init(),
acpi_parse_fadt() gets called earlier during setup_arch().

We have 4 types of x86 platforms that disable RTC:
* Intel MID
* Lguest - uses paravirt
* Xen dom-U - uses paravirt
* x86 on legacy systems annotated with an ACPI legacy flag
We can consolidate all of these into a platform specific legacy
quirk set early in boot through i386_start_kernel() and through
x86_64_start_reservations(). This deals with the RTC quirks which
we can rely on through the hardware subarch, the ACPI check can
be dealt with separately.
For Xen things are bit more complex given that the @X86_SUBARCH_XEN
x86_hardware_subarch is shared on for Xen which uses the PV path for
both domU and dom0. Since the semantics for differentiating between
the two are Xen specific we provide a platform helper to help override
default legacy features -- x86_platform.set_legacy_features(). Use
of this helper is highly discouraged, its only purpose should be
to account for the lack of semantics available within your given
x86_hardware_subarch.
As per 0-day, this bumps the vmlinux size using i386-tinyconfig as
follows:
TOTAL TEXT init.text x86_early_init_platform_quirks()
+70 +62 +62 +43
Only 8 bytes overhead total, as the main increase in size is
all removed via __init.
