We log a fake bank 128 MCE to note that we're handling a CPU thermal
event. However, this confuses people into thinking that their hardware
generates MCEs. Hijacking MCA for logging thermal events is a gross
misuse anyway and it shouldn't have been done in the first place. And
besides we have other means for dealing with thermal events which are
much more suitable.
So let's kill the MCE logging part.

"drm fixes across the board.
Okay holidays and LCA kinda caught up with me, I thought I'd get some
of this dequeued last week, but Hobart was sunny and warm and not all
gloomy and rainy as usual.
This is a bit large, but not too much considering it's two weeks stuff
from AMD and Intel.
core:
- one locking fix that helps with dynamic suspend/resume races
i915:
- mostly GVT updates, GVT was a recent introduction so fixes for it
shouldn't cause any notable side effects.

- a bunch of fixes for GPUs with a different memory controller design
that need different firmware.

a single fix for a FE hang after IOVA rollover on GC3000. This isn't
pretty, but is the minimal fix for the issue. A larger rework of the
code, that will also fix this issue properly, is currently in the works,
but that needs to wait for at least the next feature pull.

Pull libnvdimm fixes from Dan Williams:
"Two fixes:
- a regression fix for the multiple-pmem-namespace-per-region support
added in 4.9. Even if an existing environment is not using that
feature the act of creating and a destroying a single namespace
with the ndctl utility will lead to the proliferation of extra
unwanted namespace devices.
- a fix for the error code returned from the pmem driver when the
memcpy_mcsafe() routine returns -EFAULT. Btrfs seems to be the only
block I/O consumer that tries to parse the meaning of the error
code when it is non-zero.
Neither of these fixes are critical, the namespace leak is awkward in
that it can cause device naming to change and complicates debugging
namespace initialization issues. The error code fix is included out of
caution for what other consumers might be expecting -EIO for block I/O
errors"

KVM: s390: Fix for 4.10 (via kvm/master)
Fix a kernel memory exposure.
|
|
kvm_s390_get_machine() populates the facility bitmap by copying bytes
from the host results that are stored in a 256 byte array in the prefix
page. The KVM code does use the size of the target buffer (2k), thus
copying and exposing unrelated kernel memory (mostly machine check
related logout data).
Let's use the size of the source buffer instead. This is ok, as the
target buffer will always be greater or equal than the source buffer as
the KVM internal buffers (and thus S390_ARCH_FAC_LIST_SIZE_BYTE) cover
the maximum possible size that is allowed by STFLE, which is 256
doublewords. All structures are zero allocated so we can leave bytes
256-2047 unchanged.
Add a similar fix for kvm_arch_init_vm().

The warn on is a bit too much, we will anyway set the dma mask if not set
previously.
The main reason for this fix is that 4.10-rc1 has a dwc3 change that
pass a parent sysdev dev pointer instead of setting the dma mask of
its xhci platform device. xhci platform driver can then get more
attributes from the sysdev than just the dma mask.
The usb core and xhci changes are not yet in 4.10, and a fix like
this was preferred instead of taking those big changes this late in
the rc-cycle.

IBM bit 31 (for the rest of us - bit 0) is a reserved field in the
instruction definition of mtspr and mfspr. Hardware is encouraged to
(and does) ignore it.
As a result, if userspace executes an mtspr DSCR with the reserved bit
set, we get a DSCR facility unavailable exception. The kernel fails to
match against the expected value/mask, and we silently return to
userspace to try and re-execute the same mtspr DSCR instruction. We
loop forever until the process is killed.
We should do something here, and it seems mirroring what hardware does
is the better option vs killing the process. While here, relax the
matching of mfspr PVR too.

Read access to the SPI flash are broken on da850-evm, i.e. the data
read is not what is actually programmed on the flash.
According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not
usable anymore and only the FAST_READ command can be used to read data.
This commit specifies in the DTS that we should use FAST_READ command
instead of the READ command.

As virtio-1 introduced the possibility of the device manipulating the
status byte, revision 2 of the virtio-ccw transport introduced a means
of getting the status byte from the device via READ_STATUS. Let's wire
it up for revisions >= 2 and fall back to returning the stored status
byte if not supported.

Since ef1b144d ("tools/virtio/ringtest: fix run-on-all.sh to work
without /dev/cpu") run-on-all.sh uses seq 0 $HOST_AFFINITY as the list
of ids of the CPUs to run the command on (assuming ids of online CPUs
are consecutive and start from 0), where $HOST_AFFINITY is the highest
CPU id in the system previously determined using lscpu. This can fail
on systems with offline CPUs.
Instead let's use lscpu to determine the list of online CPUs.

Using control_work instead of config_work as the 3rd argument to
container_of results in an invalid portdev pointer. Indeed, the work
structure is initialized as below:
INIT_WORK(&portdev->config_work, &config_work_handler);
It leads to a crash when portdev->vdev is dereferenced later. This
bug
is triggered when the guest uses a virtio-console without multiport
feature and receives a config_changed virtio interrupt.
