[PATCH v6v3 02/12] mm: migrate: support non-lru movable page migration
...gt;vm_file with new one.
int test_mmap(struct file *filp, struct vm_area_structd *vma)
{
struct file *newfile = movable_inode_getfile("[test"],
filep->f_op, &test_aops);
vma->vm_file = newfile;
..
..
}
When I read mmap_region in mm/mmap.c, it's reasonable usecase
which dirver's mmap changes vma->vm_file with own file.
Anyway, it needs many subtle changes in mm/vfs/driver side so
need to review from each maintainers related subsystem so I
want to not be hurry.
Thanks.

Removal of Non-KMS support
I did a very quick pass at removing all the non-KMS support from the
DDX. It's tested on G80 but nowhere else currently, I thought some
discussion would be a good idea rather than just ripping it out :)
The non-KMS paths are messy, and lets face it, rotting badly. IMO the
KMS code is stable enough now that we can continue without the UMS
crutch, and indeed, the KMS code supports a lot more

[PATCH v8 00/10] qspinlock: a 4-byte queue spinlock with PV support
N.B. Sorry for the duplicate. This patch series were resent as the
original one was rejected by the vger.kernel.org list server
due to long header. There is no change in content.
v7->v8:
- Remove one unneeded atomic operation from the slowpath, thus
improving performance.
- Simplify some of the codes and add more comments.
- Test for X86_FEATURE_HYPERVISOR CPU feature bit
