When using modern dai_link style, we must first make sure the
struct snd_soc_dai_link_component exists before accessing its members.
In case of early probe deferral, some of the '.cpus' or '.codecs' may not
have been allocated yet. Check this before calling of_node_put() on the
structure member.

Keeping the irq_chip definition static shares it with multiple instances
of the altera gpiochip in the system. This is bad and now we get this
warning from gpiolib core:
"detected irqchip that is shared with multiple gpiochips: please fix the
driver."
Hence, move the irq_chip definition from being driver static into the
struct altera_gpio_chips. So a unique irq_chip is used for each gpiochip
instance.

This driver was using the OF GPIO helper API, but barely used any of its
features and it cost more code than it saved. Also, the OF GPIO code is
now deprecated. Convert it to use a more standard setup and use devm
APIs for initialization to avoid the need for a remove function.
Our rationale for this change is that we are using the Xilinx GPIO with
resources injected using the MFD core rather than on the device tree
itself. Using platform rather than OF-specific resources allows this to
work for free.

This adds the required infrastructure for manually updated displays,
such as DSI command mode panels. While those panels often support
partial updates we currently always do a full refresh.
The display will be refreshed when something calls the dirty callback,
such as libdrm's drmModeDirtyFB(). This is currently being done at least
by the kernel console and Xorg (with modesetting driver) in their
default configuration. Weston does not implement this and the fbdev
backend does not work (display will not update). Weston's DRM backend
uses double buffering and the page flip will also trigger a display
refresh.

While most display types only forward their VM to the DISPC, this
is not true for DSI. DSI calculates the VM for DISPC based on its
own, but it's not identical. Actually the DSI VM is not even a valid

and avoid checking the DISPC VM for DSI here.

So long as a struct hmm pointer exists, so should the struct mm it is
linked too. Hold the mmgrab() as soon as a hmm is created, and mmdrop() it
once the hmm refcount goes to zero.
Since mmdrop() (ie a 0 kref on struct mm) is now impossible with a !NULL
mm->hmm delete the hmm_hmm_destroy().

Ralph observes that hmm_range_register() can only be called by a driver
while a mirror is registered. Make this clear in the API by passing in the
mirror structure as a parameter.
This also simplifies understanding the lifetime model for struct hmm, as
the hmm pointer must be valid as part of a registered mirror so all we
need in hmm_register_range() is a simple kref_get.

In set_pte_at(), we read the old pte value so that it can be passed into
checks for racy hw updates. These checks are only performed for
CONFIG_DEBUG_VM, and the value is not used otherwise.
Since we read the pte value with READ_ONCE(), the compiler cannot elide
the redundant read for !CONFIG_DEBUG_VM kernels.
Let's ameliorate matters by moving the read and the checks into a
helper, __check_racy_pte_update(), which only performs the read when the
value will be used. This also allows us to reformat the conditions for
clarity.

If a fresh array block is allocated during resize, the current in-memory
set size should be increased by the size of the block, not replaced by it.
Before the fix, adding entries to a hash set type, leading to a table
resize, caused an inconsistent memory size to be reported. This becomes
more obvious when swapping sets with similar sizes:
# cat hash_ip_size.sh
#!/bin/sh

ipset create t1 hash:ip

ipset add t1 1.2.$((i / 255)).$((i % 255))
done
t1_init="$(ipset list t1|sed -n 's/Size in memory: \(.*\)/\1/p')"
ipset create t2 hash:ip
for i in `seq 1 4360`; do
ipset add t2 1.2.$((i / 255)).$((i % 255))
done
t2_init="$(ipset list t2|sed -n 's/Size in memory: \(.*\)/\1/p')"
ipset swap t1 t2
t1_swap="$(ipset list t1|sed -n 's/Size in memory: \(.*\)/\1/p')"
