Fix the unnecessary periodic wakeups of discard thread that happens under
below two conditions -
1. When f2fs is heavily utilized over 80%, the current discard policy
sets the max sleep timeout of discard thread as 50ms
(DEF_MIN_DISCARD_ISSUE_TIME). But this is set even when there are
no pending discard commands to be issued.
2. In the issue_discard_thread() path when there are no pending discard
commands, it fails to reset the wait_ms to max timeout value.

Freescale/NXP i.MX8 QXP and QM SoCs. Hence add a dependency on
ARCH_MXC, to prevent asking the user about this driver when configuring
a kernel without i.MX8 support.
Drop the "default m" (which means "default y" if CONFIG_MODULES is not
enabled), as merely enabling CONFIG_COMPILE_TEST should not enable
additional code.

Updates binding document since the avc and vp8 hardware encoder in
MT8173 are now separated. Separate "mediatek,mt8173-vcodec-enc" to
"mediatek,mt8173-vcodec-enc-vp8" and "mediatek,mt8173-vcodec-enc".
This patch is not a compatible change, but we must do this modifaction
because MediaTek IOMMU add the device_link between the smi-larb
device and venc_device, if the venc device call the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.
There is a bit of backward compatibility for avc encoder, the avc
encoder device node still has compatible "mediatek,mt8173-vcodec-enc".

When a request is re-inited it will release all control handler
objects that are still in the request. It does that by unbinding
and putting all those objects. When the object is unbound the
obj->req pointer is set to NULL, and the object's unbind op is
called. When the object it put the object's release op is called
to free the memory.
For a request object that contains a control handler that means
that v4l2_ctrl_handler_free() is called in the release op.
A control handler used in a request has a pointer to the main
control handler that is created by the driver and contains the
current state of all controls. If the device is unbound (due to
rmmod or a forced unbind), then that main handler is freed, again
by calling v4l2_ctrl_handler_free(), and any outstanding request
objects that refer to that main handler have to be unbound and put
as well.
It does that by this test:
if (!hdl->req_obj.req && !list_empty(&hdl->requests)) {
I.e. the handler has no pointer to a request, so is the main
handler, and one or more request objects refer to this main
handler.
However, this test is wrong since hdl->req_obj.req is actually
NULL when re-initing a request (the object unbind will set req to
NULL), and the only reason this seemingly worked is that the
requests list is typically empty since the request's unbind op
will remove the handler from the requests list.
But if another thread is at the same time adding a new control
to a request, then there is a race condition where one thread
is removing a control handler object from the requests list and
another thread is adding one. The result is that hdl->requests
is no longer empty and the code thinks that a main handler is
being freed instead of a control handler that is part of a request.
There are two bugs here: first the test for hdl->req_obj.req: this
should be hdl->req_obj.ops since only the main control handler will
have a NULL pointer there.
The second is that adding or deleting request objects from the
requests list of the main handler isn't protected by taking the
main handler's lock.

When in vcodec_control_v4() on the 4xx path we select between one of two
vcodec cores to toggle power control bits. In 6xx there is only one core
which offsets the relevant control registers to a slightly different
address.
This patch accounts for the address offset for 6xx silicon.

The tests exercise the VGIC_V3 device creation including the
associated KVM_DEV_ARM_VGIC_GRP_ADDR group attributes:
- KVM_VGIC_V3_ADDR_TYPE_DIST/REDIST
- KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION
Some other tests dedicate to KVM_DEV_ARM_VGIC_GRP_REDIST_REGS group
and especially the GICR_TYPER read. The goal was to test the case
recently fixed by commit 23bde34771
("KVM: arm64: vgic-v3: Drop the reporting of GICR_TYPER.Last for userspace").

In various places in the venus codebase we have if (IS_V4()) which takes
the code down paths for 4xx silicon. This logic is broadly applicable to
6xx silicon also. In this patch we add IS_V6() to various IS_V4() decision
locations.

Commit 23bde34771 ("KVM: arm64: vgic-v3: Drop the
reporting of GICR_TYPER.Last for userspace") temporarily fixed
a bug identified when attempting to access the GICR_TYPER
register before the redistributor region setting, but dropped
the support of the LAST bit.
Emulating the GICR_TYPER.Last bit still makes sense for
architecture compliance though. This patch restores its support
(if the redistributor region was set) while keeping the code safe.
We introduce a new helper, vgic_mmio_vcpu_rdist_is_last() which
computes whether a redistributor is the highest one of a series
of redistributor contributor pages.
With this new implementation we do not need to have a uaccess
read accessor anymore.

vgic_uaccess() takes a struct vgic_io_device argument, converts it
to a struct kvm_io_device and passes it to the read/write accessor
functions, which convert it back to a struct vgic_io_device.
Avoid the indirection by passing the struct vgic_io_device argument
directly to vgic_uaccess_{read,write}.

vgic_v3_insert_redist_region() may succeed while
vgic_register_all_redist_iodevs fails. For example this happens
while adding a redistributor region overlapping a dist region. The
failure only is detected on vgic_register_all_redist_iodevs when
vgic_v3_check_base() gets called in vgic_register_redist_iodev().
In such a case, remove the newly added redistributor region and free
it.

KVM_DEV_ARM_VGIC_GRP_ADDR group doc says we should return
-EEXIST in case the base address of the redist is already set.
We currently return -EINVAL.
However we need to return -EINVAL in case a legacy REDIST address
is attempted to be set while REDIST_REGIONS were set. This case
is discriminated by looking at the count field.
