Commit 7db551fcfb2a ("mm/damon/reclaim: support addr_unit for
DAMON_RECLAIM") introduced the 'addr_unit' parameter for DAMON_RECLAIM.
But the usage document is not updated for that. Update the document.

Committing a monitoring target with empty target regions is for keeping
the current monitoring results. This behavior was introduced by commit
973233600676 ("mm/damon/sysfs: update monitoring target regions for online
input commit"). The behavior is not documented, though. Update the usage
document for clarifying this behavior.

The kernel can throttle network sockets if the memory cgroup associated
with the corresponding socket is under memory pressure. The throttling
actions include clamping the transmit window, failing to expand receive or
send buffers, aggressively prune out-of-order receive queue, FIN deferred
to a retransmitted packet and more. Let's add memcg metric to track such
throttling actions.
At the moment memcg memory pressure is defined through vmpressure and in
future it may be defined using PSI or we may add more flexible way for the
users to define memory pressure, maybe through ebpf. However the
potential throttling actions will remain the same, so this newly
introduced metric will continue to track throttling actions irrespective
of how memcg memory pressure is defined.

Add AST2700 to the list of supported SoCs in the ASPEED FMC/SPI bindings.
AST2700 FMC/SPI controllers are not compatible with AST2600 due to the
following hardware differences:
- Address decoding unit uses 64KB granularity (AST2600 uses 1MB).
- Segment register semantics are changed.
AST2600: start <= range <= end
AST2700: start <= range < end
- Hardware limitations in AST2600 address decoding registers have been
resolved in AST2700, so extra callback function used for bug fixup
is no longer required.
These differences require distinct compatible strings for AST2700.

PCI/TSM sysfs for physical function 0 devices, i.e. the "DSM" (Device
Security Manager), contains the 'connect' and 'disconnect' attributes.
After a successful 'connect' operation the DSM, its dependent functions
(SR-IOV virtual functions, non-zero multi-functions, or downstream
endpoints of a switch DSM) are candidates for being transitioned into a
TDISP (TEE Device Interface Security Protocol) operational state, via
pci_tsm_bind(). At present sysfs is blind to which devices are capable of
TDISP operation and it is ambiguous which functions are serviced by which
DSMs.
Add a 'dsm' attribute to identify a function's DSM device, and add a
'bound' attribute to identify when a function has entered a TDISP
operational state.

The current kernel doesn't handle unpopulated cgroups any special
regarding reclaim protection. Furthermore, this wasn't a case even when
this was introduced in
bf8d5d52ffe89 ("memcg: introduce memory.min")
Drop the incorrect documentation. (Implementation taking into account
the inner-node constraint may be added later.)

For lack of a better place to put it, Resizable BAR code has been placed
inside pci.c and setup-res.c that do not use it for anything. Upcoming
changes are going to add more Resizable BAR related functions, increasing
the code size.
As pci.c is huge as is, move the Resizable BAR related code and the BAR
resize code from setup-res.c to rebar.c.
