commit 8b38694a2d
vhost/net: virtio 1.0 byte swap
had this chunk:
- heads[headcount - 1].len += datalen;
+ heads[headcount - 1].len = cpu_to_vhost32(vq, len - datalen);
This adds datalen with the wrong sign, causing guest panics.

The reason we defer kfree until release function is because it's a
general rule for kobjects: kfree of the reference counter itself is only
legal in the release function.
Previous patch didn't make this clear, document this in code.

A struct device which has just been unregistered can live on past the
point at which a driver decides to drop it's initial reference to the
kobject gained on allocation.
This implies that when releasing a virtio device, we can't free a struct
virtio_device until the underlying struct device has been released,
which might not happen immediately on device_unregister().
Unfortunately, this is exactly what virtio pci does:
it has an empty release callback, and frees memory immediately
after unregistering the device.
This causes an easy to reproduce crash if CONFIG_DEBUG_KOBJECT_RELEASE
it enabled.
To fix, free the memory only once we know the device is gone in the release
callback.

It turns out we need to add device-specific code

This is a set of three fixes: one to correct an abort path thinko causing

order issue in the fnic driver and one to match discard expectations to qemu
which otherwise cause Linux to behave badly as a guest.

Commit ac61d19559 (scsi: set correct completion code in
scsi_send_eh_cmnd()) introduced a bug. It changed the stored return
value from a queuecommand call, but it didn't take into account that
the return value was used again later on. This patch fixes the bug by
changing the later usage.
There is a big comment in the middle of scsi_send_eh_cmnd() which
does a good job of explaining how the routine works. But it mentions
a "rtn = FAILURE" value that doesn't exist in the code. This patch
adjusts the code to match the comment (I assume the comment is right
and the code is wrong).
This fixes Bugzilla #88341.

When I/O is aborted by mid-layer, fnic FW will complete the I/O before

In this case firmware reset would clear the inconsistent state.

7985090aa0 changed the discard heuristics to give preference to the
WRITE SAME commands that (unlike UNMAP) guarantee deterministic results.
Ming Lei discovered that QEMU SCSI's WRITE SAME implementation
internally relied on limits that were only communicated for the UNMAP
case. And therefore discard commands backed by WRITE SAME would fail.
Tweak the heuristics so we still pick UNMAP in the LBPRZ=0 case and only
prefer the WRITE SAME variants if the device has the LBPRZ flag set.

After the commit ef691ff48b (OMAPDSS: DT: Get source endpoint by
matching reg-id) we look for the SDI output using the port number.
However, the SDI driver doesn't set the port number, which causes the
SDI display to not initialize.
Fix this by setting the SDI port number to 1. We use a hardcoded value,
as SDI was used only on OMAP3 and it's always port number 1 there.

Pull thermal management updates from Zhang Rui:
"First of all, the most important change is the thermal cpu cooling
fixes. The major fix here is to have proper sequencing between
cpufreq layer and thermal cpu cooling registration. A take away of
this fix is an improvement in the thermal drivers code. Thermal
drivers that require cpu cooling do not need to check for cpufreq
layer. The requirement now is to propagate the error code, if any,
while registering cpu cooling device. Thanks to Viresh for
implementing the required CPUfreq changes.
Second, a new driver is introduced for int340x processor thermal
device. Given that int340x thermal is disabled by default, and this
processor thermal device is only available on limited platforms, plus
the driver does nothing but exposes some thermal limitation
information for user space to use, thus I think it is safe to include
it in this pull request after missing 3.19-rc2.
Specifics:
- Thermal cpu cooling fixes and cleanups.
- introduce INT340X processor thermal reporting device driver.
- several small fixes and cleanups for int340x thermal drivers"

virtio 1.0 only requires used address to be 4 byte aligned,
vhost required 8 bytes (size of vring_used_elem).
Fix up vhost to match that.
Additionally, while vhost correctly requires 8 byte
alignment for log, it's unconnected to used ring:
it's a consequence that log has u64 entries.
Tweak code to make that clearer.

If the probe of an fb driver has been deferred due to missing
dependencies, and the probe is later ran when a module is loaded, the
fbdev framework will try to find a logo to use.
However, the logos are __initdata, and have already been freed. This
causes sometimes page faults, if the logo memory is not mapped,
sometimes other random crashes as the logo data is invalid, and
sometimes nothing, if the fbdev decides to reject the logo (e.g. the
random value depicting the logo's height is too big).
This patch adds a late_initcall function to mark the logos as freed. In
reality the logos are freed later, and fbdev probe may be ran between
this late_initcall and the freeing of the logos. In that case we will
miss drawing the logo, even if it would be possible.

GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.
This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.
By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.

Use generic config_init callback also for KSZ8021 and KSZ8031.
This has been avoided this far due to commit b838b4aced ("phy/micrel:
KSZ8031RNL RMII clock reconfiguration bug"), which claims that the PHY
becomes unresponsive if the broadcast-disable flag is set before
configuring the clock mode.
Turns out that the problem seemingly worked-around by the above
mentioned commit was really due to a hardware-configuration issue, where
the PHY was in fact strapped to address 3 rather than 0.
