39c6b3a3dd of: fdt: Remove weak early_init_dt_mark_hotplug_memory_arch() 
Commit 41a9ada3e6 ("of/fdt: mark hotpluggable memory") introduced
two (for systems with and without memblock) weak versions of
early_init_dt_mark_hotplug_memory_arch(), that could be overridden by an
architecture-specific version.  However, no overrides ever emerged.
Later, commit aca52c3983 ("mm: remove CONFIG_HAVE_MEMBLOCK")
removed the non-memblock version.

Remove early_init_dt_mark_hotplug_memory_arch(), and replace it by a
direct call to memblock_mark_hotplug().

7da6ebf5f5 dt-bindings: arm: Convert Gemini boards to YAML 
This removes the old plaintext Gemini binding and replace it
with a YAML schema, adding some new boards in the process.
While we are at it, add the missing vendors to the vendor
prefix file.

Drop the overly deliberate description of subnodes and the big
example from the old document. Keep the elaborate description.

I noticed that "wiliboard" is not a real vendor, the vendor
is named "wiligear" so deprecated this and replaced with the
proper vendor.

As the:

eb7173988c of: fdt: remove unnecessary codes 
While unflattening the device tree, we try to populate dt nodes and
properties into tree-shaped data structure.

In populate_properties function, pprev is initially set to
&np->properties, and then updated to &pp->next.

In both scenarios *pprev is NULL, since the memory area that we are
allocating from is initially zeroed.

I tested the code as below, and it showed that BUG was never called.

-       if (!dryrun)
+       if (!dryrun) {
+               if (*pprev)
+                       BUG();
                *pprev = NULL;
+       }

Let's remove unnecessary code.

ace1c4b5c4 of: base: remove unnecessary for loop 
In __of_get_next_child function, loop iteration for getting next node is
unnecessary.

for loop is already checking if next is NULL or not, and
of_node_get(next) always returns next itself.

Therefore checking return value in the if clause always evaluates to
true, and thus it always breaks out from for loop in the first iteration.

Remove the unnecessary for loop for readability.

I tested the code as below, and it showed that BUG was never called.

-       for (; next; next = next->sibling)
+       for (; next; next = next->sibling) {
                if (of_node_get(next))
                        break;
+               BUG();
+       }

The K3 AM64x SoCs also have a ICSSG IP that is similar to existing K3
AM65x and J721E SoCs. The ICSSG interrupt controller is identical to
that of the INTC on J721E SoCs, and supports 20 host interrupts and
160 input events from various SoC interrupt sources. All the 8 output
host interrupts are routed to multiple entities though. Update the
PRUSS interrupt controller binding with this information, though the
same K3 compatible shall be used for the ICSSG INTC on AM64x SoCs.

023e1a8dd5 mm/rmap: fix new bug: premature return from page_mlock_one() 
In the unlikely race case that page_mlock_one() finds VM_LOCKED has been
cleared by the time it got page table lock, page_vma_mapped_walk_done()
must be called before returning, either explicitly, or by a final call
to page_vma_mapped_walk() - otherwise the page table remains locked.

d9770fcc1c mm/rmap: fix old bug: munlocking THP missed other mlocks 
The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.

It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped.  Refine the tests.

There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.

(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

comments: try_to_migrate_one() also accepts TTU_SYNC (already commented
in try_to_migrate() itself), and try_to_migrate() returns nothing at
all.

TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it
in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so
delete the "recently referenced" comment from try_to_unmap_one() (once
upon a time the comment was near the removed codeblock, but they drifted
apart).
