reasons:
- only one plane is active and thus it can be blended only with

drm/i915: Add "panel orientation" property to the panel connector, v6.
Ideally we could use the VBT for this, that would be simple, in
intel_dsi_init() check dev_priv->vbt.dsi.config->rotation, set
connector->display_info.panel_orientation accordingly and call
drm_connector_init_panel_orientation_property(), done.
Unfortunately vbt.dsi.config->rotation is always 0 even on tablets
with an upside down LCD and where the GOP is properly rotating the
EFI fb in hardware.
So instead we end up reading the rotation from the primary plane.
This commit only implements the panel orientation property for DSI
panels on BYT / CHT hardware, as all known non normal oriented panels
sofar are only found on this hardware.
Changes in v2:
-Read back the rotation applied by the GOP from the primary plane
instead of relying on dev_priv->vbt.dsi.config->rotation, because it
seems that the VBT rotation filed is always 0 even on devices where the
GOP does apply a rotation
Changes in v3:
-Rewrite the code to read back the orientation from the primary
plane to contain all of this in intel_dsi.c instead of poking a bunch
of holes between all the different layers

drm: Add support for a panel-orientation connector property, v6
On some devices the LCD panel is mounted in the casing in such a way that
the up/top side of the panel does not match with the top side of the
device (e.g. it is mounted upside-down).
This commit adds the necessary infra for lcd-panel drm_connector-s to
have a "panel orientation" property to communicate how the panel is
orientated vs the casing.
Userspace can use this property to check for non-normal orientation and
then adjust the displayed image accordingly by rotating it to compensate.
Changes in v2:
-Store panel_orientation in drm_display_info, so that drm_fb_helper.c can
access it easily
-Have a single drm_connector_init_panel_orientation_property rather then
create and attach functions. The caller is expected to set
drm_display_info.panel_orientation before calling this, then this will
check for platform specific quirks overriding the panel_orientation and if
the panel_orientation is set after this then it will attach the property.

DRM_MODE_PANEL_ORIENTATION_*

drm: Add panel orientation quirks, v6.
Some x86 clamshell design devices use portrait tablet screens and a display
engine which cannot rotate in hardware, so the firmware just leaves things
as is and we cannot figure out that the display is oriented non upright
from the hardware.
So at least on x86, we need a quirk table for this. This commit adds a DMI
based quirk table which is initially populated with 5 such devices: Asus
T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17.
This quirk table will be used by the drm code to let userspace know that
the display is not mounted upright inside the devices case through a new
panel orientation drm-connector property, as well as to tell fbcon to
rotate the console so that it shows the right way up.
Changes in v5:
-Add a kernel-doc comment documenting drm_get_panel_orientation_quirk()
-Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop,
keeping only the (identical) sys_vendor and product_name matches.
This is necessary because an older version of the bios has
board_vendor set to VOIS instead of VIOS

drm/prime: skip CPU sync in map/unmap dma_buf
Dma-bufs should already be device coherent, as they are only pulled in the
CPU domain via the begin/end cpu_access calls. As we cache the mapping set
up by dma_map_sg a CPU sync at this point will not actually guarantee proper
coherency on non-coherent architectures, so we can as well stop pretending.
This is an important performance fix for architectures which need explicit
cache synchronization and userspace doing lots of dma-buf imports.
Improves Weston on Etnaviv performance 5x, where before this patch > 90%

"This contains a handful of small cleanups that are a result of
feedback that didn't make it into our original patch set, either
because the feedback hadn't been given yet, I missed the original
emails, or we weren't ready to submit the changes yet.
I've been maintaining the various cleanup patch sets I have as their
own branches, which I then merged together and signed. Each merge
commit has a short summary of the changes, and each branch is based on
your latest tag (4.15-rc1, in this case). If this isn't the right way
to do this then feel free to suggest something else, but it seems sane
to me.
Here's a short summary of the changes, roughly in order of how
interesting they are.
- libgcc.h has been moved from include/lib, where it's the only
member, to include/linux. This is meant to avoid tab completion
conflicts.
- VDSO entries for clock_get/gettimeofday/getcpu have been added.
These are simple syscalls now, but we want to let glibc use them
from the start so we can make them faster later.
- A VDSO entry for instruction cache flushing has been added so
userspace can flush the instruction cache.
- The VDSO symbol versions for __vdso_cmpxchg{32,64} have been
removed, as those VDSO entries don't actually exist.
- __io_writes has been corrected to respect the given type.
- A new READ_ONCE in arch_spin_is_locked().
- __test_and_op_bit_ord() is now actually ordered.
- Various small fixes throughout the tree to enable allmodconfig to
build cleanly.
- Removal of some dead code in our atomic support headers.

arm64: fpsimd: Fix failure to restore FPSIMD state after signals
The fpsimd_update_current_state() function is responsible for
loading the FPSIMD state from the user signal frame into the
current task during sigreturn. When implementing support for SVE,
conditional code was added to this function in order to handle the
case where SVE state need to be loaded for the task and merged with
the FPSIMD data from the signal frame; however, the FPSIMD-only
case was unintentionally dropped.
As a result of this, sigreturn does not currently restore the
FPSIMD state of the task, except in the case where the system
supports SVE and the signal frame contains SVE state in addition to
FPSIMD state.
This patch fixes this bug by making the copy-in of the FPSIMD data
from the signal frame to thread_struct unconditional.
This remains a performance regression from v4.14, since the FPSIMD
state is now copied into thread_struct and then loaded back,
instead of _only_ being loaded into the CPU FPSIMD registers.
However, it is essential to call task_fpsimd_load() here anyway in
order to ensure that the SVE enable bit in CPACR_EL1 is set
correctly before returning to userspace. This could use some
refactoring, but since sigreturn is not a fast path I have kept
this patch as a pure fix and left the refactoring for later.

arm64: ftrace: emit ftrace-mod.o contents through code
When building the arm64 kernel with both CONFIG_ARM64_MODULE_PLTS and
CONFIG_DYNAMIC_FTRACE enabled, the ftrace-mod.o object file is built
with the kernel and contains a trampoline that is linked into each
module, so that modules can be loaded far away from the kernel and
still reach the ftrace entry point in the core kernel with an ordinary
relative branch, as is emitted by the compiler instrumentation code
dynamic ftrace relies on.
In order to be able to build out of tree modules, this object file
needs to be included into the linux-headers or linux-devel packages,
which is undesirable, as it makes arm64 a special case (although a
precedent does exist for 32-bit PPC).
Given that the trampoline essentially consists of a PLT entry, let's
not bother with a source or object file for it, and simply patch it
in whenever the trampoline is being populated, using the existing
PLT support routines.

(1) When checking the result of the kzalloc(), we can't just return, but

need to keep the pointer stable so that we can check to see if
vnode->permit_cache has changed before we decide whether to assign to
it.
(3) 'permits' is being put twice.

"These fix a regression related to the ACPI EC handling during system
suspend/resume on some platforms and prevent modalias from being
exposed to user space for ACPI device object with "not functional and
not present" status.
Specifics:
- Fix an ACPI EC driver regression (from the 4.9 cycle) causing the
driver's power management operations to be omitted during system
suspend/resume on platforms where the EC instance from the ECDT
table is used instead of the one from the DSDT (Lv Zheng).
- Prevent modalias from being exposed to user space for ACPI device
objects with _STA returning 0 (not present and not functional) to
prevent driver modules from being loaded automatically for hardware
that is not actually present on some platforms (Hans de Goede)"
