fbdev is in maintenance only, except that it's still used by drm
through the drm fbdev emulation, to be able to use fbcon. And people
might want to sometimes extend fbcon to enable new features for drm
drivers, e.g. Hans' panel orientation work.
The problem is that when those patches only touch fbdev code they'll
never show up on drm developer's radar, which means we end up with
designs that don't really fit whell into the full stack. That happened
a bit with the panel orientation work, where an fbcon patch made it
into 4.14, implementing a design that won't really work on the drm
side. Which means we now have to redo things, and on top coordinate 2
subsystem trees.
Since fbdev is super low-volume we can prevent this in the future by
simply adding the dri-devel mailing list to the fbdev subsystem.

- Avoid dereferencing an unprotected VMA pointer in the fault signal

- Fix inline asm call constraints for GCC 4.4
- Use existing register variable to retrieve the stack pointer
instead of forcing the compiler to create another indirect access
which results in excessive extra 'mov %rsp, %<dst>' instructions

an early boot crash
- Fix a sparse warning caused by casting the __user annotation in

Pull timer fixes from Thomas Gleixner:
"This adds a new timer wheel function which is required for the
conversion of the timer callback function from the 'unsigned long
data' argument to 'struct timer_list *timer'. This conversion has two
benefits:
1) It makes struct timer_list smaller
2) Many callers hand in a pointer to the timer or to the structure
containing the timer, which happens via type casting both at setup
and in the callback. This change gets rid of the typecasts.
Once the conversion is complete, which is planned for 4.15, the old
setup function and the intermediate typecast in the new setup function
go away along with the data field in struct timer_list.
Merging this now into mainline allows a smooth queueing of the actual
conversion in the affected maintainer trees without creating
dependencies"

rollback handling as well"

Pull locking fixes from Thomas Gleixner:
"Two fixes for locking:
- Plug a hole the pi_stat->owner serialization which was changed
recently and failed to fixup two usage sites.
- Prevent reordering of the rwsem_has_spinner() check vs the
decrement of rwsem count in up_write() which causes a missed
wakeup"

the MIPS GIC irq driver

The cma drivers use the drm_gem_framebuffer_helper functions now,
so remove drm_fb_cma_destroy, drm_fb_cma_create_handle,
drm_fb_cma_create_with_funcs, drm_fb_cma_create and
drm_fb_cma_prepare_fb.

The functions tve200_display_disable and tve200_display_funcs are
local to the source and do not need to be in global scope, so make
them static.
Cleans up sparse warnings:
symbol 'tve200_display_disable' was not declared. Should it be static?
symbol 'tve200_display_funcs' was not declared. Should it be static?
