77167b966b docs: submitting-patches: clarify the role of LKML 
The documentation previously stated that LKML should be used as *last
resort*. However, scripts/get_maintainer.pl always suggests it and in a
discussion about changing that[0] it turned out that LKML should in fact
receive all patches.

Update documentation to make it clear that all patches should be sent to
LKML by default, in addition to any subsystem-specific lists.

21de80b53b LICENSES/dual/CC-BY-4.0: Git rid of "smart quotes" 
A couple of exotic quote characters came in with this license text; they
can confuse software that is not expecting non-ASCII text.  Switch to
normal quotes here, with no changes to the actual license text.

40751c6c9b scripts/spdxcheck.py: Strictly read license files in utf-8 
Commit bc41a7f364 ("LICENSES: Add the CC-BY-4.0 license")
unfortunately introduced LICENSES/dual/CC-BY-4.0 in UTF-8 Unicode text
While python will barf at it with:

FAIL: 'ascii' codec can't decode byte 0xe2 in position 2109: ordinal not in range(128)
Traceback (most recent call last):
  File "scripts/spdxcheck.py", line 244, in <module>
    spdx = read_spdxdata(repo)
  File "scripts/spdxcheck.py", line 47, in read_spdxdata
    for l in open(el.path).readlines():
  File "/usr/lib/python3.6/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 2109: ordinal not in range(128)

While it is indeed debatable if 'Licensor.' used in the license file
needs unicode quotes, instead, force spdxcheck to read utf-8.

6c855fce2e mm/rmap: try_to_migrate() skip zone_device !device_private 
I know nothing about zone_device pages and !device_private pages; but if
try_to_migrate_one() will do nothing for them, then it's better that
try_to_migrate() filter them first, than trawl through all their vmas.

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)

64b586d192 mm/rmap: fix comments left over from recent changes 
Parallel developments in mm/rmap.c have left behind some out-of-date
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).
