There is a user who do not want to use CMA memory for migration. Until
now, it is implemented by caller side but it's not optimal since there
is limited information on caller. This patch implements it on callee side
to get better result.

From: Joonsoo Kim
Currently, page allocation functions for migration requires some arguments.
More worse, in the following patch, more argument will be needed to unify
the similar functions. To simplify them, in this patch, unified data
structure that controls allocation behaviour is introduced.
From: Joonsoo Kim
To prepare unifying duplicated functions in following patches, this patch
changes the interface of the migration target alloc/free functions.
Functions now use struct alloc_control as an argument.
There is no functional change.

Hi Gavin,
I definitely appreciate the work, but this is repeating most of the
mistakes done in the x86 implementation. In particular:
- the page ready signal can be done as an interrupt, rather than an
exception. This is because "page ready" can be handled asynchronously,
in contrast to "page n

This commit exports 'do_madvise()' to external GPL modules, so that
other modules including DAMON could use the function.

DAMON can be used as a primitive for data access pattern aware memory
management optimizations. However, users who want such optimizations
should run DAMON, read the monitoring results, analyze it, plan a new
memory management scheme, and apply the new scheme by themselves.
The comment for ntb_peer_spad_addr and ntb_peer_spad_read
incorrectly referred to peer doorbell register and local
scratchpad register.

Linux Kernel Mentee: Remove Legacy Power Management.
The purpose of this patch series is to remove legacy power management callbacks
from amd ethernet drivers.
The callbacks performing suspend() and resume() operations are still calling

Ville, this is a v2 of the GPIO ABI we discussed with some time ago.
If you have time to briefly look at it and perhaps comment if it's
right way to go.

Drivers should not save device registers and/or change the power state of
the device. As per the generic PM approach, these are handled by PCI core.
The driver should support dev_pm_ops callbacks and bind them to pci_driver.

Use dev_pm_ops structure to call generic suspend() and resume() callbacks.
Drivers should avoid saving device register and/or change power states
using PCI helper functions. With generic approach, all these are handled by
PCI core.

To tune the DAMON-based operation schemes, knowing how many and how
large regions are affected by each of the schemes will be helful. Those
stats could be used for not only the tuning, but also monitoring of the

Remove legacy PM callbacks and use generic operations. With legacy code,
drivers were responsible for handling PCI PM operations like
"pci_save_state()". In generic code, all these handled by PCI core.
