drm/core: Do not preserve framebuffer on rmfb, v4.
It turns out that preserving framebuffers after the rmfb call breaks
vmwgfx userspace. This was originally introduced because it was thought
nobody relied on the behavior, but unfortunately it seems there are
exceptions.
drm_framebuffer_remove may fail with -EINTR now, so a straight revert
is impossible. There is no way to remove the framebuffer from the lists
and active planes without introducing a race because of the different
locking requirements. Instead call drm_framebuffer_remove from a
workqueue, which is unaffected by signals.
Changes since v1:
- Add comment.
Changes since v2:
- Add fastpath for refcount = 1. (danvet)
Changes since v3:
- Rebased.
- Restore lastclose framebuffer removal too.

Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
nonblocking ioctl and async flip (= not vblank synced), from Maarten.
Needs to be regened with newer drivers, but probably only after -rc1 to
catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.

The driver has to provide a (struct drm_framebuffer_funcs *)->dirty()

If the dirty() hook is set, then fb_deferred_io is set up automatically

Two functions have been added so that the driver can provide a dirty()
function:
- drm_fbdev_cma_init_with_funcs()
This makes it possible for the driver to provided a custom

fbdev: fb_defio: Export fb_deferred_io_mmap
Export fb_deferred_io_mmap so drivers can change vma->vm_page_prot.
When the framebuffer memory is allocated using dma_alloc_writecombine()
instead of vmalloc(), I get cache syncing problems on ARM.
This solves it:
static int drm_fbdev_cma_deferred_io_mmap(struct fb_info *info,
struct vm_area_struct *vma)
{
fb_deferred_io_mmap(info, vma);
vma->vm_page_prot = pgprot_writecombine(vma->vm_page_prot);
return 0;
}
Could this have been done in the core?
Drivers that don't set (struct fb_ops *)->fb_mmap, gets a call to
fb_pgprotect() at the end of the default fb_mmap implementation
(drivers/video/fbdev/core/fbmem.c). This is an architecture specific
function that on many platforms uses pgprot_writecombine(), but not on
all. And looking at some of the fb_mmap implementations, some of them
sets vm_page_prot to nocache for instance, so I think the safest bet is
to do this in the driver and not in the fbdev core. And we can't call
fb_pgprotect() from fb_deferred_io_mmap() either because we don't have
access to the file pointer that powerpc needs.
