"Just a couple of fixups for Synaptics RMI4 driver and allowing

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: synaptics-rmi4 - write config register values to the right offset
Input: synaptics-rmi4 - fix possible double free
Input: snvs_pwrkey - make it depend on ARCH_MXC
This way, slhc_free() accepts what slhc_init() returns, whether that is
an error or not.
In particular, the pattern in sl_alloc_bufs() is
slcomp = slhc_init(16, 16);
...
slhc_free(slcomp);
for the error handling path, and rather than complicate that code, just
make it ok to always free what was returned by the init function.
That's what the code used to do before commit 4ab42d78e3 ("ppp, slip:
Validate VJ compression slot parameters completely") when slhc_init()
just returned NULL for the error case, with no actual indication of the
details of the error.

When scheduling work item to read page we need to pass down the proper
bvec struct which points to the page to read into. Before this patch it
uses a randomly initialized bvec (only if PAGE_SIZE != 4096) which is
wrong.
Note that without this patch on arch/kernel where PAGE_SIZE != 4096
userspace could read random memory through a zram block device (thought
userspace probably would have no control on the address being read).

When the maximum send wr delivered by the user is zero, the qp does not
have a sq.
When allocating the sq db buffer to store the user sq pi pointer and map
it to the kernel mode, max_send_wr is used as the trigger condition, while
the kernel does not consider the max_send_wr trigger condition when
mapmping db. It will cause sq record doorbell map fail and create qp fail.

Remove the check for IOMMU presence since it was considered a
layer violation.
This means we have no reliable way to destinguish between coherent
hardware IOMMU DMA address translations and incoherent SWIOTLB DMA
address translations, which we can't handle. So always presume the
former. This means that if anybody forces SWIOTLB without also setting
the vmw_force_coherent=1 vmwgfx option, driver operation will fail,
like it will on most other graphics drivers.

When this code was consolidated the intention was that the VMA would
become backed by anonymous zero pages after the zap_vma_pte - however this
very subtly relied on setting the vm_ops = NULL and clearing the VM_SHARED
bits to transform the VMA into an anonymous VMA. Since the vm_ops was
removed this broke.
Now userspace gets a SIGBUS if it touches the vma after disassociation.
Instead of converting the VMA to anonymous provide a fault handler that
puts a zero'd page into the VMA when user-space touches it after
disassociation.

"We interrupt your regularly scheduled drm fixes for a regression
special.
The first is for a fix in i915 that had unexpected side effects
fallout in the userspace X.org modesetting driver where X would no
longer start. I got tired of the nitpicking and issued a large hammer
on it. The X.org driver is buggy, but blackscreen regressions are
worse.
The second was an oversight that myself and Gerd should have noticed
better, Gerd is trying to fix this properly, but the regression is too
large to leave, even if the original behaviour is bad in some cases,
it's clearly bad to break a bunch of working use cases.
I'll likely have a regular fixes pull later, but I really wanted to

This patch does more harm than good, as it breaks both Xwayland and
gnome-shell with X11.
Xwayland requires DRI3 & DRI3 requires PRIME.
X11 crash for obscure double-free reason which are hard to debug
(starting X11 by hand doesn't trigger the crash).
I don't see an apparent problem implementing those stub prime
functions, they may return an error at run-time, and it seems to be
handled fine by GNOME at least.
This reverts commit b318e3ff7c.

This broke userspace for virtio-gpus, and regressed things from DRI3 to DRI2.

The tx_status poll in the rcar_dmac driver reads the status register
which indicates which chunk is busy (DMACHCRB). Afterwards the point
inside the chunk is read from DMATCRB. It is possible that the chunk
has changed between the two reads. The result is a non-monotonous
increase of the residue. Fix this by introducing a 'safe read' logic.

If we add a bond device which is already the master of the team interface,
we will hold the team->lock in team_add_slave() first and then request the
lock in team_set_mac_address() again. The functions are called like:
- team_add_slave()
- team_port_add()
- team_port_enter()
- team_modeop_port_enter()
- __set_port_dev_addr()
- dev_set_mac_address()
- bond_set_mac_address()
- dev_set_mac_address()
- team_set_mac_address
Although team_upper_dev_link() would check the upper devices but it is
called too late. Fix it by adding a checking before processing the slave.
