Currently cleaned_count is initialized to ICE_DESC_UNUSED(rx_ring) and
later on during the Rx processing it is incremented per each frame that
driver consumed. This can result in excessive buffers requested from xsk
pool based on that value.
To address this, just drop cleaned_count and pass
ICE_DESC_UNUSED(rx_ring) directly as a function argument to
ice_alloc_rx_bufs_zc(). Idea is to ask for buffers as many as consumed.
Let us also call ice_alloc_rx_bufs_zc unconditionally at the end of
ice_clean_rx_irq_zc. This has been changed in that way for corresponding
ice_clean_rx_irq, but not here.

The descriptor that ntu is pointing at when we exit
ice_alloc_rx_bufs_zc() should not have its corresponding DD bit cleared
as descriptor is not allocated in there and it is not valid for HW
usage.
The allocation routine at the entry will fill the descriptor that ntu
points to after it was set to ntu + nb_buffs on previous call.
Even the spec says:
"The tail pointer should be set to one descriptor beyond the last empty
descriptor in host descriptor ring."
Therefore, step away from clearing the status_error0 on ntu + nb_buffs
descriptor.

The 'if (ntu == rx_ring->count)' block in ice_alloc_rx_buffers_zc()
was previously residing in the loop, but after introducing the
batched interface it is used only to wrap-around the NTU descriptor,
thus no more need to assign 'xdp'.

Currently, the zero-copy data path is reusing the memory region that was
initially allocated for an array of struct ice_rx_buf for its own
purposes. This is error prone as it is based on the ice_rx_buf struct
always being the same size or bigger than what the zero-copy path needs.
There can also be old values present in that array giving rise to errors
when the zero-copy path uses it.
Fix this by freeing the ice_rx_buf region and allocating a new array for
the zero-copy path that has the right length and is initialized to zero.

Currently we only NULL the xdp_buff pointer in the internal SW ring but
we never give it back to the xsk buffer pool. This means that buffers
can be leaked out of the buff pool and never be used again.
Add missing xsk_buff_free() call to the routine that is supposed to
clean the entries that are left in the ring so that these buffers in the
umem can be used by other sockets.
Also, only go through the space that is actually left to be cleaned
instead of a whole ring.

Some systems (e.g. Hyper-V guests) have all their memory marked as
hotpluggable in SRAT. acpi_numa_memory_affinity_init(), however,
ignores all such regions when !CONFIG_MEMORY_HOTPLUG and this is
unfortunate as memory affinity (NUMA) information gets lost.
'Hot Pluggable' flag in SRAT only means that "system hardware supports
hot-add and hot-remove of this memory region", it doesn't prevent
memory from being cold-plugged there.
Ignore 'Hot Pluggable' bit instead of skipping the whole memory
affinity information when !CONFIG_MEMORY_HOTPLUG.

ACPICA code takes care about cache flushing on S1/S2/S3 in
acpi_hw_extended_sleep() and acpi_hw_legacy_sleep().
acpi_suspend_enter() calls into ACPICA code via acpi_enter_sleep_state()
for S1 or x86_acpi_suspend_lowlevel() for S3.
acpi_sleep_prepare() call tree:
__acpi_pm_prepare()
acpi_pm_prepare()
acpi_suspend_ops::prepare_late()
acpi_hibernation_ops::pre_snapshot()
acpi_hibernation_ops::prepare()
acpi_suspend_begin_old()
acpi_suspend_begin_old::begin()
acpi_hibernation_begin_old()
acpi_hibernation_ops_old::acpi_hibernation_begin_old()
acpi_power_off_prepare()
pm_power_off_prepare()
Hibernation (S4) and Power Off (S5) don't require cache flushing, so
the only interesting callsites are acpi_suspend_ops::prepare_late()
and acpi_suspend_begin_old::begin(). Both of them have cache flush
on ->enter() operation in acpi_suspend_enter().
Remove redundant ACPI_FLUSH_CPU_CACHE() in acpi_sleep_prepare() and
acpi_suspend_enter().

Play a video on the raven (or PCO, raven2) platform, and then do the S3
test. When resume, the following error will be reported:
amdgpu 0000:02:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring
vcn_dec test failed (-110)
[drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block

amdgpu 0000:02:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110
[why]
When playing the video: The power state flag of the vcn block is set to
POWER_STATE_ON.
When doing suspend: There is no change to the power state flag of the
vcn block, it is still POWER_STATE_ON.
When doing resume: Need to open the power gate of the vcn block and set
the power state flag of the VCN block to POWER_STATE_ON.
But at this time, the power state flag of the vcn block is already
POWER_STATE_ON. The power status flag check in the "8f2cdef drm/amd/pm:
avoid duplicate powergate/ungate setting" patch will return the
amdgpu_dpm_set_powergating_by_smu function directly.
As a result, the gate of the power was not opened, causing the
subsequent ring test to fail.
[how]
In the suspend function of the vcn block, explicitly change the power
state flag of the vcn block to POWER_STATE_OFF.

The variable tmp is being masked with a bitmask and the value is being
written to port base + 0x3c. However, the masked value is being written
back to tmp and tmp is never used after this. The assignmentment is
redundant, replace the &= operator with just &.

Accessing platform device resources directly has long been deprecated for
DT as IRQ resources may not be available at device creation time. Drivers
continuing to use static IRQ resources is blocking removing the static setup
from the DT core code.

The sh-sci driver supports up to four input clocks, of which only the
first one is mandatory.
Replace devm_clk_get() and custom error checking by
devm_clk_get_optional(), to simplify the code and to catch all real
errors.

Since commit 1b463bd51042927e ("ARM: dts: r8a7794: Rename the serial
port clock to fck") in v4.6, all upstream DTS files call the SCIF
functional clock "fck".
Hence the time is ripe to drop backward-compatibility with old DTBs that
use the old "sci_ick" name.

This, in particular, prevents GPIO library to use it for different
