The watchdog clock should be disable in dw_wdt_suspend, but we set a
dummy clock to watchdog for rk3288. So the watchdog will continue to
work during suspend. And we switch the system clock to 32khz from 24Mhz,
during suspend, so the watchdog timer over count will increase to
755 times, about 12.5 hours, the original value is 60 seconds. So
watchdog will reset the system over a night, but voltage are all
incorrect, then it hang on reset.

The kernel's pgd_index macro is designed to index a normal, page
sized array. KVM is a bit diffferent, as we can use concatenated
pages to have a bigger address space (for example 40bit IPA with
4kB pages gives us an 8kB PGD.
In the above case, the use of pgd_index will always return an index
inside the first 4kB, which makes a guest that has memory above
0x8000000000 rather unhappy, as it spins forever in a page fault,
whist the host happilly corrupts the lower pgd.
The obvious fix is to get our own kvm_pgd_index that does the right
thing(tm).
Tested on X-Gene with a hacked kvmtool that put memory at a stupidly
high address.

CPU0: stopping
A possible approach for this is to split the compound page using
split_page() at allocation time, and change the teardown path to
free one page at a time. It turns out that alloc_pages_exact() and
free_pages_exact() does exactly that.
While we're at it, the PGD allocation code is reworked to reduce
duplication.
This has been tested on an X-Gene platform with a 4kB/48bit-VA host
kernel, and kvmtool hacked to place memory in the second page of
the hardware PGD (PUD for the host kernel). Also regression-tested
on a Cubietruck (Cortex-A7).

When generic pm domain support is enabled, the PGC can be used
to completely gate power to the PU power domain containing GPU3D,
GPU2D, and VPU cores.
This code triggers the PGC powerdown sequence to disable the GPU/VPU
isolation cells and gate power and then disables the PU regulator.
To reenable, the reverse powerup sequence is triggered after the PU
regulator is enabled again.
The GPU and VPU devices in the PU power domain temporarily need
to be clocked during powerup, so that the reset machinery can work.

The da9210 regulator is connected to IRQ2. Reflect this in its device
node, so the driver can use it when it gains interrupt support.

Add a device node for the da9063 PMIC, with subnodes for rtc and wdt.
Regulator support is not yet included.
This allows the system to be restarted when the watchdog timer times
out, or when a system restart is requested.

The r8a7790/lager and r8a7791/koelsch development boards have da9063 and
da9210 regulators. Both regulators have their interrupt request lines
tied to the same interrupt pin (IRQ2) on the SoC.
After cold boot or da9063-induced restart, both the da9063 and da9210
seem to assert their interrupt request lines. Hence as soon as one
driver requests this irq, it gets stuck in an interrupt storm, as it
only manages to deassert its own interrupt request line, and the other
driver hasn't installed an interrupt handler yet.
To handle this, install a quirk that masks the interrupts in both the
da9063 and da9210. This quirk has to run after the i2c master driver
has been initialized, but before the i2c slave drivers are initialized.
As it depends on i2c, select I2C if one of the affected platforms is
enabled in the kernel config.
On koelsch, the following happens:
- Cold boot or reboot using the da9063 restart handler:
IRQ2 is asserted, installing da9063/da9210 regulator quirk
...
i2c i2c-6: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb
i2c 6-0058: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb
i2c 6-0058: Detected da9063
i2c 6-0058: Masking da9063 interrupt sources
i2c 6-0068: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb
i2c 6-0068: Detected da9210
i2c 6-0068: Masking da9210 interrupt sources
i2c 6-0068: IRQ2 is not asserted, removing quirk
- Warm boot (reset button):
rcar_gen2_regulator_quirk: IRQ2 is not asserted, not installing quirk

It can be useful to dump the page table entries when an unhandled data
abort fault occurs. This can aid debugging of these situations, for
example, a STREX instruction causing an external abort on non-linefetch
fault, as has been reported recently.

When validating the mask against the amount of memory we have available
(so that we can trap 32-bit DMA addresses with >32-bits memory), we had
not taken account of the fact that max_pfn is the maximum PFN number
plus one that would be in the system.
There are several references in the code which bear this out:
mm/page_owner.c:
for (; pfn < max_pfn; pfn++) {
}
arch/x86/kernel/setup.c:
high_memory = (void *)__va(max_pfn * PAGE_SIZE - 1)
