Update DAMON design document's DAMOS filters section for address range
DAMOS filters. Because address range filters are handled by the core
layer and it makes difference in schemes tried regions and schemes
statistics, clearly describe it.

The background and concept of DAMOS is redundantly documented, in the
design document and the usage document. Replace the duplicated ones in
usage document with links to the design document.

Patch series "Docs/{mm,admin-guide}damon: update design and usage docs".
Update DAMON design and usage documents for outdated and unnecessarily
duplicated parts.
This patch (of 7):
The 'age' of each region in DAMON monitoring results is an important
concept for both monitoring part and DAMOS. And DAMOS section of the
design document is mentioning it. However, the age itself is not
explained in the document. Add a section for that.

DAMOS is an important part of DAMON, but the design doc is not covering

DAMON design document is describing only the operations set layer and
monitoring part of the core logic. Update the layout based on the DAMON's
layers, so that more parts of DAMON including DAMOS core logic and DAMON
modules can easily be added.

Patch series "Docs/mm/damon: Minor fixes and design doc update".
Some of the DAMON documents are outdated, or having minor typos or grammar
erros. Especially, the design doc has not updated for DAMOS, which is an
important part of DAMON. Fix the minor issues and update documents.
This patch (of 10):
The first two questions of DAMON faqs have raised when DAMON patches were
first submitted. More than one year has passed since DAMON patches get
merged in the mainline, and that kind of questions are not asked nowadays.
Remove the questions.

What DAMON aims to do is not only access monitoring but efficient and
effective access-aware system operations. And DAMon-based Operation
Schemes (DAMOS) is the important feature of DAMON for the goal. Make the
intro of DAMON documentation to emphasize the goal and mention DAMOS.
