d8b8eb829d Merge branch 'drm-rockchip-next-fixes-2016-01-22' of https://github.com/markyzq/kernel-drm-rockchip into drm-fixes
Here are some fixes for drm/rockchip, these fixes base on drm-next.

These fixes works on my popmetal(rk3288) board.

About patch: drm/atomic-helper: Export framebuffer_changed()
Daniel Vetter ack for merging it through rockchip git trees, so framebuffer_changed() can be reused by drm/rockchip.

All others looks good, so I'd like you can land them.

2081e78a5c Merge branch 'drm-etnaviv-fixes' of git://git.pengutronix.de/git/lst/linux into drm-fixes
A bunch of etnaviv fixes for 4.5-rc. Most of them are fixing
things in code paths that will only be hit if something goes
wrong, which have been unearthed by more extensive testing.

The only thing that doesn't really qualify as fixes is an UAPI
extension that userspace wants to rely on being present, so
I want to fast-track this into 4.5 before etnaviv ends up in a
released kernel.

28b8d66e0c drm/amdgpu: only move pt bos in LRU list on success
This fixes a race condition in the error case: since the pt bos have not
necessarily been reserved in case of an error, we could move a pt bo that
is currently in the middle of being evicted/moved by another process,
which then resulted in a BUG_ON in ttm_bo_add_to_lru.

a0a5ab3e99 drm/etnaviv: call correct function when trying to vmap a DMABUF
When trying to get the vmap address of an imported buffer, we must
call into the appropriate helper function, to allow the exporter to
establish the vmap, instead of trying to vmap the buffer on our own.

Add an indirection through etnaviv_gem_ops to allow the correct
implementation to be called.

In case that etnaviv_gem_get_pages is unable to get the required

this case instead of propagating the error, as callers of this

NULL in case of an error.

f95429eccc drm/radeon: only init fbdev if we have connectors
This fixes an issue that was noticed on an optimus/prime laptop with
a kernel that was old enough to not support the integrated intel gfx
(which was driving all the outputs), but did have support for the
discrete radeon gpu.  The end result was not falling back to VESA and
leaving the user with a black screen.

(Plus it is kind of silly to create an framebuffer device if there
are no outputs hooked up to the gpu.)

6b31de3e69 ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi list
Like the Yoga 900 models the Lenovo Yoga 700 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

587198ba52 vmstat: Remove BUG_ON from vmstat_update
If we detect that there is nothing to do just set the flag and do not
check if it was already set before.  Races really do not matter.  If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.

Since commit 0eb77e9880 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd.  This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up.  The VM_BUG_ON is therefore misleading and no more
appropriate.  Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly.  Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

Add dummy.o to the targets list, and fill targets automatically from

When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.
