Commit 553f770ef7 ("ipc: move compat shmctl to native") moved the
compat IPC syscall handling into ipc/shm.c and refactored the struct
accessors in the process. Unfortunately, the call to
copy_compat_shmid_to_user when handling a compat {IPC,SHM}_STAT command
gets the arguments the wrong way round, passing a kernel stack address
as the user buffer (destination) and the user buffer as the kernel stack
address (source).
This patch fixes the parameter ordering so the buffers are accessed
correctly.

The "Release:" field of the spec file is determined based on the
.version file.
However, the .version file is not copied to the source tar file.
So, when we build the kernel from the source package, the UTS_VERSION
always indicates #1. This does not match with "rpm -q".
The kernel UTS_VERSION and "rpm -q" do not agree for binrpm-pkg, either.
Please note the kernel has already been built before the spec file is
created. Currently, mkspec invokes mkversion. This script returns an
incremented version. So, the "Release:" field of the spec file is
greater than the version in the kernel by one.
For the source package build (where .version file is missing), we can
give KBUILD_BUILD_VERSION=%{release} to the build command.
For the binary package build, we can simply read out the .version file
because it contains the version number that was used for building the
kernel image.
We can remove scripts/mkversion because scripts/package/Makefile need
not touch the .version file.

Commit df85b2d767 ("firmware: Restore support for built-in firmware")

When reading data from trace_pipe, tracing_wait_pipe() performs a
check to see if tracing has been turned off after some data was read.
Currently, this check always looks at global trace state, but it
should be checking the trace instance where trace_pipe is located at.
Because of this bug, cat instances/i1/trace_pipe in the following
script will immediately exit instead of waiting for data:
cd /sys/kernel/debug/tracing
echo 0 > tracing_on
mkdir -p instances/i1
echo 1 > instances/i1/tracing_on

One convenient way to erase trace is "echo > trace". However, this
is currently broken if the current tracer is irqsoff tracer. This
is because irqsoff tracer use max_buffer as the default trace
buffer.
Set the max_buffer as the one to be cleared when it's the trace
buffer currently in use.

WARN_ON_ONCE(pi_test_sn(&vmx->pi_desc)) in kvm_vcpu_trigger_posted_interrupt()
intends to detect the violation of invariant that VT-d PI notification
event is not suppressed when vcpu is in the guest mode. Because the
two checks for the target vcpu mode and the target suppress field
cannot be performed atomically, the target vcpu mode may change in
between. If that does happen, WARN_ON_ONCE() here may raise false
alarms.
As the previous patch fixed the real invariant breaker, remove this
WARN_ON_ONCE() to avoid false alarms, and document the allowed cases
instead.

In kvm_vcpu_trigger_posted_interrupt() and pi_pre_block(), KVM
assumes that PI notification events should not be suppressed when the
target vCPU is not blocked.
vmx_update_pi_irte() sets the SN field before changing an interrupt
from posting to remapping, but it does not check the vCPU mode.
Therefore, the change of SN field may break above the assumption.
Besides, I don't see reasons to suppress notification events here, so
remove the changes of SN field to avoid race condition.

Commit 7d902c05b4 ("drm: Nuke drm_atomic_helper_connector_dpms")
removed drm_atomic_helper_connector_dpms() helper saying that it was a dead
code. It was however indirectly used by Exynos DRM driver for implementing
suspend/resume support. To fix this regression (after that patch Exynos DRM
suspend/resume functions became no-ops and hardware fails to suspend),
this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.

replaced unsafe drm_for_each_connector() with drm_for_each_connector_iter()
and removed surrounding drm_modeset_lock calls. However, that lock was
there not only to protect unsafe drm_for_each_connector(), but it was also
required to be held by the dpms code which was called from the loop body.
This patch restores those drm_modeset_lock calls to fix broken suspend
and resume of Exynos DRM subsystem in v4.13 kernel.

This reverts commit 36ae3c0a36.
The commit broke compilation on !CONFIG_HAVE_KVM_IRQ_ROUTING. Also,
there may be cases with CONFIG_HAVE_KVM_IRQ_ROUTING, where larger
gsi values make sense.
As the commit was meant as an early indicator to user space that
something is wrong, reverting just restores the previous behavior
where overly large values are ignored when encountered (without

This reverts commit bbdf0b2ff3 ("drm/i915/bxt: Disable device ready

Disable device ready before shutdown command was added previously to
avoid a split screen issue seen on dual link DSI panels. As of now, dual
link is not supported and will need some rework in the upstream
code. For single link DSI panels, the change is not required. This will
cause failure in sending SHUTDOWN packet during disable. Hence reverting
the change. Will handle the change as part of dual link enabling in
upstream.

Looking at our virtual PCI device, we can see surprising Region 4 and Region 5.
00:10.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 06) (prog-if 00 [VGA controller])
....
Region 0: Memory at 140000000 (64-bit, non-prefetchable) [size=16M]
Region 2: Memory at 180000000 (64-bit, prefetchable) [size=1G]
Region 4: Memory at <ignored> (32-bit, non-prefetchable)
Region 5: Memory at <ignored> (32-bit, non-prefetchable)
Expansion ROM at febd6000 [disabled] [size=2K]
The fact is that we only implemented BAR0 and BAR2. Surprising Region 4 and
Region 5 are shown because we report their size as 0xffffffff. They should
report size 0 instead.
BTW, the physical GPU has a PIO BAR. GVTg hasn't implemented PIO access, so
we ignored this BAR for vGPU device.
v2: fix BAR size value calculation.

spi_nor_read_sfdp() calls nor->read() to read the SFDP data.
When the m25p80 driver is used (pretty common case), nor->read() is then
implemented by the m25p80_read() function, which is likely to initialize a
'struct spi_transfer' from its buf argument before appending this
structure inside the 'struct spi_message' argument of spi_sync().
Besides the SPI sub-system states that both .tx_buf and .rx_buf members of
'struct spi_transfer' must point into dma-safe memory. However, two of the
three calls of spi_nor_read_sfdp() were given pointers to stack allocated
memory as buf argument, hence not in a dma-safe area.
Hopefully, the third and last call of spi_nor_read_sfdp() was already
given a kmalloc'ed buffer argument, hence dma-safe.
So this patch fixes this issue by introducing a
spi_nor_read_sfdp_dma_unsafe() function which simply wraps the existing
spi_nor_read_sfdp() function and uses some kmalloc'ed memory as a bounce
buffer.

One field of the flash parameter table contains information about the
flash device size.
Most of the time the data extracted from this field is valid, but
sometimes the BFPT section of the SFDP table is corrupted or invalid and
this field is set to 0xffffffff, thus resulting in an integer overflow
when setting params->size.
Since NOR devices are anayway always smaller than 2^64 bytes, we can
easily stop the BFPT parsing if the size reported in this table is
invalid.

With the need to discourage use of less secure dialect, SMB1 (CIFS),
we temporarily upgraded the dialect to SMB3 in 4.13, but since there
are various servers which only support SMB2.1 (2.1 is more secure
than CIFS/SMB1) but not optimal for a default dialect - add support
for multidialect negotiation. cifs.ko will now request SMB2.1
or later (ie SMB2.1 or SMB3.0, SMB3.02) and the server will
pick the latest most secure one it can support.
In addition since we are sending multidialect negotiate, add
support for secure negotiate to validate that a man in the
middle didn't downgrade us.
