The UART’s software and hardware flow control are currently not
functioning correctly.
For software flow control, the following error is encountered:
qcom_geni_serial 1a80000.serial: Couldn't find suitable
clock rate for 56000000, 3500000, 2500000, 1152000, 921600, 19200
During hardware flow control testing, a “Retry 0: Got ZCAN error” is
observed.
To address these issues, update the UART frequency table to include all
supported frequencies according to the frequency plan.

BRANCH_HALT_ENABLE and BRANCH_HALT_ENABLE_VOTED flags are used to check
halt status of branch clocks, which have an inverted logic for the halt
bit in CBCR register. However, the current logic in the _check_halt()
method only compares the BRANCH_HALT_ENABLE flags, ignoring the votable
branch clocks.
Update the logic to correctly handle the invert logic for votable clocks
using the BRANCH_HALT_ENABLE_VOTED flags.

If regmap_read() fails, random stack value was used in calculating new
frequency in recalc_rate() callbacks. Such failure is really not
expected as these are all MMIO reads, however code should be here
correct and bail out. This also avoids possible warning on

When a clock-controller lists multiple power-domains we need make each GDSC a
subdomain of each of the clock-controller's listed power-domains.
GDSCs without an explicitly defined parent should be a subdomain of each of
the clock-controller's listed power-domains.
GDSCs with an explicitly defined parent should attach only to the parent
GDSC and not the listed power-domains. Any votes will trickle through the
hierarchy up to the external power-domains.

Right now we support one power-domain per clock controller.
These single power-domains are switched on by the driver platform logic.
However when we have multiple power-domains attached to a clock-controller
that list of power-domains must be handled outside of driver platform
logic.
Use devm_pm_domain_attach_list() to automatically hook the list of given
power-domains in the dtsi for the clock-controller driver.

Update some RCGs on the sm8250 camera clock controller to use
clk_rcg2_shared_ops. The shared_ops ensure the RCGs get parked
to the XO during clock disable to prevent the clocks from locking up
when the GDSC is enabled. These mirror similar fixes for other controllers
such as commit e5c359f70e4b ("clk: qcom: camcc: Update the clock ops for

The GPU clock is required for CPU access to GPUSS registers. It was
previously decided (on this and many more platforms) that the added
overhead/hassle introduced by keeping track of it would not bring much
measurable improvement in the power department.
The display clock is basically the same story over again.
Now, we're past that discussion and this commit is not trying to change
that. Instead, the clocks are both force-enabled in .probe *and*
registered with the common clock framework, resulting in them being
toggled off after ignore_unused.
Unregister said clocks to fix breakage when clk_ignore_unused is absent
(as it should be).

gather_bootmem_prealloc() assumes the start nid as 0 and size as
num_node_state(N_MEMORY). That means in case if memory attached numa
nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail
to scan few of these nodes.
Since memory attached numa nodes can be interleaved in any fashion, hence
ensure that the current code checks for all numa node ids
(.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that
it can distributes all nr_node_ids among the these many no. threads.

========================
numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20"

We can run into an infinite loop in __get_longterm_locked() when
collect_longterm_unpinnable_folios() finds only folios that are isolated
from the LRU or were never added to the LRU. This can happen when all
folios to be pinned are never added to the LRU, for example when
vm_ops->fault allocated pages using cma_alloc() and never added them to
the LRU.
Fix it by simply taking a look at the list in the single caller, to see if
anything was added.

There is a code error that will cause the swap entry allocator to reclaim
and check the whole cluster with an unexpected tail offset instead of the
part that needs to be reclaimed. This may cause corruption of the swap
map, so fix it.

On NUMA systems, __GFP_THISNODE indicates that an allocation _must_ be on
a particular node, and failure to allocate on the desired node will result
in a failed allocation.
Skip __GFP_THISNODE allocations if we are running on a NUMA system, since
KFENCE can't guarantee which node its pool pages are allocated on.
