When building with ARCH=i386, readq and writeq are not defined,
resulting in:
intel_uncore.h: In function ‘__raw_uncore_read64’:
intel_uncore.h:257:9: error: implicit declaration of function ‘readq’;
did you mean ‘readl’? [-Werror=implicit-function-declaration]

write##s__(val, uncore->regs + i915_mmio_reg_offset(reg)); \
^
Add the io-64-nonatomic-lo-hi include to have readq and writeq available
for all builds. This header internally includes linux/io.h, so the
native readq and writeq definitions will be used when available.

A few advantages:
- Prepares us for the planned split of display uncore from GT uncore
- Improves our engine-centric view of the world in the engine code
and allows us to avoid jumping back to dev_priv.
- Allows us to wrap accesses to engine register in nice macros that
automatically pick the right mmio base.

KMS drivers really should all be able to restore their display state
on resume without fbcon helping out. So make this the default.
Since I'm not entirely foolish, make it only a default, which drivers
can still override. That way when the inevitable regression report
happens I can fix things up with a one-liner plus FIXME comment that
someone should fix up the suspend/resume code in that driver.
But at least all new drivers won't be broken by accident as soon as
you turn off fbcon because "suspend/resume worked when I tested it".

Iterate over child devices instead of ports in parse_ddi_ports() to
initialize ddi_port_info. We'll eventually need to decide some stuff
based on the child device order, which may be different from the port
order.
As a bonus, this allows better abstractions for e.g. dvo port mapping.
There's a subtle change in the DDC pin and AUX channel sanitization as
we change the order. Otherwise, this should not change behaviour.

The AGPBUSY thing doesn't work on i945gm anymore. This means
the gmch is incapable of waking the CPU from C3 when an interrupt
is generated. The interrupts just get postponed indefinitely until
something wakes up the CPU. This is rather annoying for vblank
interrupts as we are unable to maintain a steady framerate
unless the machine is sufficiently loaded to stay out of C3.
To combat this let's use pm_qos to prevent C3 whenever vblank
interrupts are enabled. To maintain reasonable amount of powersaving
we will attempt to limit this to C3 only while leaving C1 and C2
enabled.

Since commit b7137e0cf1 ("drm/i915: Defer enabling rc6 til after we
submit the first batch/context"), intel_suspend_gt_powersave() has been
a no-op. As we still do not need to do anything explicitly on suspend
(we do everything required on idling), remove the defunct function.

Pull perf updates from Thomas Gleixner:
"A larger set of perf updates.
Not all of them are strictly fixes, but that's solely the tip
maintainers fault as they let the timely -rc1 pull request fall
through the cracks for various reasons including travel. So I'm
sending this nevertheless because rebasing and distangling fixes and
updates would be a mess and risky as well. As of tomorrow, a strict
fixes separation is happening again. Sorry for the slip-up.
Kernel:
- Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different
consumers of the mmap event get what they requested.
Tools:
- A larger set of updates to perf record/report/scripts vs. time
stamp handling
- More Python3 fixups
- A pile of memory leak plumbing
- perf BPF improvements and fixes
- Finalize the perf.data directory storage"

tooling - Linus ]

Initially found issue with closed context debug check when pin
hw_id for GVT context, looks we should always pin hw_id for that
as GVT context is fixed for each vGPU life cycle, and we'd also
like to get pinned hw_id e.g for perf reason, etc.
