It seems trigger cannot be configured too early, otherwise it does not work in
case of panel. The patch fixes also trigger flag logic, previously HW-TRIGGER
flag was cleared in case of panel - as a result panel used always software
trigger.

The regulators may not be available just because their driver's probe
function was just not executed and so the regulators not registered.
So, in this case the Exynos HDMI driver should not print logs since
a -EPROBE_DEFER is not really an error and that will just pollute
the kernel log and confuse users.
This patch prevents the following misleading messages to be printed:
[ 1.443638] [drm:hdmi_probe] *ERROR* failed to get regulators

Reading the KVM_CAP_MIPS_FPU capability returns cpu_has_fpu, however
this uses smp_processor_id() to read the current CPU capabilities (since
some old MIPS systems could have FPUs present on only a subset of CPUs).
We don't support any such systems, so work around the warning by using
raw_cpu_has_fpu instead.
We should probably instead claim not to support FPU at all if any one
CPU is lacking an FPU, but this should do for now.

There are a couple of places in KVM fault handling code which implicitly
use smp_processor_id() via kvm_mips_get_kernel_asid() and
kvm_mips_get_user_asid() from preemptable context. This is unsafe as a
preemption could cause the guest kernel ASID to be changed, resulting in
a host TLB entry being written with the wrong ASID.
Fix by disabling preemption around the kvm_mips_get_*_asid() call and
the corresponding kvm_mips_host_tlb_write().

Writing CP0_Compare clears the timer interrupt pending bit
(CP0_Cause.TI), but this wasn't being done atomically. If a timer
interrupt raced with the write of the guest CP0_Compare, the timer
interrupt could end up being pending even though the new CP0_Compare is
nowhere near CP0_Count.
We were already updating the hrtimer expiry with
kvm_mips_update_hrtimer(), which used both kvm_mips_freeze_hrtimer() and
kvm_mips_resume_hrtimer(). Close the race window by expanding out
kvm_mips_update_hrtimer(), and clearing CP0_Cause.TI and setting
CP0_Compare between the freeze and resume. Since the pending timer
interrupt should not be cleared when CP0_Compare is written via the KVM
user API, an ack argument is added to distinguish the source of the
write.

There's a particularly narrow and subtle race condition when the
software emulated guest timer is frozen which can allow a guest timer
interrupt to be missed.
This happens due to the hrtimer expiry being inexact, so very
occasionally the freeze time will be after the moment when the emulated
CP0_Count transitions to the same value as CP0_Compare (so an IRQ should
be generated), but before the moment when the hrtimer is due to expire
(so no IRQ is generated). The IRQ won't be generated when the timer is
resumed either, since the resume CP0_Count will already match CP0_Compare.
With VZ guests in particular this is far more likely to happen, since
the soft timer may be frozen frequently in order to restore the timer
state to the hardware guest timer. This happens after 5-10 hours of
guest soak testing, resulting in an overflow in guest kernel timekeeping
calculations, hanging the guest. A more focussed test case to
intentionally hit the race (with the help of a new hypcall to cause the
timer state to migrated between hardware & software) hits the condition
fairly reliably within around 30 seconds.
Instead of relying purely on the inexact hrtimer expiry to determine
whether an IRQ should be generated, read the guest CP0_Compare and
directly check whether the freeze time is before or after it. Only if
CP0_Count is on or after CP0_Compare do we check the hrtimer expiry to
determine whether the last IRQ has already been generated (which will
have pushed back the expiry by one timer period).

Revert "ARM: dts: porter: Enable SCIF_CLK frequency and pins"

Make it possible to name the producer side of a GPIO line using
a "gpio-line-names" property array, modeled on the
"clock-output-names" property from the clock bindings.
This naming is especially useful for:
- Debugging: lines are named after function, not just opaque
offset numbers.
- Exploration: systems where some or all GPIO lines are available
to end users, such as prototyping, one-off's "makerspace usecases"
users are helped by the names of the GPIO lines when tinkering.
This usecase has been surfacing recently.
The gpio-line-names attribute is completely optional.

arch_mmap_rnd, cpu_have_feature, and arch_randomize_brk are all
defined as globally visible variables.
However the files they are defined in do not include the header files
with the declaration. To avoid a possible mismatch add the missing
include statements so we have proper type checking in place.
