The flag was introduced by commit 78afd5612d ("mm: add
__GFP_OTHER_NODE flag") to allow proper accounting of remote node
allocations done by kernel daemons on behalf of a process - e.g.
khugepaged.
After "mm: fix remote numa hits statistics" we do not need and actually
use the flag so we can safely remove it because all allocations which
are satisfied from their "home" node are accounted properly.

* The order of these masks is important. Matching masks will be seen
|
|
* first and the left over flags will end up showing by themselves.
|
|
*
|
|
* For example, if we have GFP_KERNEL before GFP_USER we wil get:
|
|
*
|
|
* GFP_KERNEL|GFP_HARDWALL
|
|
*
|
|
* Thus most bits set go first.
