CR4 isn't constant; at least the TSD and PCE bits can vary.
TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
like it's correct.
This adds a branch and a read from cr4 to each vm entry. Because it is
extremely likely that consecutive entries into the same vcpu will have
the same host cr4 value, this fixes up the vmcs instead of restoring cr4
after the fact. A subsequent patch will add a kernel-wide cr4 shadow,
reducing the overhead in the common case to just two memory reads and a
branch.

Drivers: ide: Remove typedef atiixp_ide_timing
Commit b0c29f79ec (futexes: Avoid taking the hb->lock if there's
nothing to wake up) changes the futex code to avoid taking a lock when
there are no waiters. This code has been subsequently fixed in commit
11d4616bd0 (futex: revert back to the explicit waiter counting code).
Both the original commit and the fix-up rely on get_futex_key_refs() to
always imply a barrier.
However, for private futexes, none of the cases in the switch statement
of get_futex_key_refs() would be hit and the function completes without
a memory barrier as required before checking the "waiters" in
futex_wake() -> hb_waiters_pending(). The consequence is a race with a
thread waiting on a futex on another CPU, allowing the waker thread to
read "waiters == 0" while the waiter thread to have read "futex_val ==
locked" (in kernel).
Without this fix, the problem (user space deadlocks) can be seen with
Android bionic's mutex implementation on an arm64 multi-cluster system.

replaces mii_bus with a generic host_dev, and introduces
dsa_host_dev_to_mii_bus() to support conversion from host_dev to mii_bus.
However, in some cases it uses to_mii_bus to perform that conversion.
Since host_dev is not the phy bus device but typically a platform device,
this fails and results in a crash with the affected drivers.

In commit ec8a2e5621 ("tipc: same receive

the possiblilty that an arriving message extracted from a bundle buffer
may be a multicast message. Such messages need to be to be delivered to
the socket via a separate function, tipc_sk_mcast_rcv(). As a result,
small multicast messages arriving as members of a bundle buffer will be
silently dropped.
This commit corrects the error by considering this case in the function

If megaflows are disabled, the userspace does not send the netlink attribute
OVS_FLOW_ATTR_MASK, and the kernel must create an exact match mask.
sw_flow_mask_set() sets every bytes (in 'range') of the mask to 0xff, even the
bytes that represent padding for struct sw_flow, or the bytes that represent
fields that may not be set during ovs_flow_extract().
This is a problem, because when we extract a flow from a packet,
we do not memset() anymore the struct sw_flow to 0.
This commit gets rid of sw_flow_mask_set() and introduces mask_set_nlattr(),
which operates on the netlink attributes rather than on the mask key. Using
this approach we are sure that only the bytes that the user provided in the
flow are matched.
Also, if the parse_flow_mask_nlattrs() for the mask ENCAP attribute fails, we
now return with an error.

So that when an evsel is embedded into other struct it can free up
resources calling perf_evsel__exit().

Instead of using a module parameter, we should detect the errata via
PCI DID and then set an appropriate flag. This will be used for additional
errata later on.

This reverts commit 9c3b306e1c.
Switching only one commit root during a transaction is wrong because it
leads the fs into an inconsistent state. All commit roots should be
switched at once, at transaction commit time, otherwise backref walking
can often miss important references that were only accessible through
the old commit root. Plus, the root item for the snapshot's root wasn't
getting updated and preventing the next transaction commit to do it.
This made several users get into random corruption issues after creation
of readonly snapshots.
A regression test for xfstests will follow soon.

Explicitly set the dr_mode for the second dwc3 controller on the
Arndale Octa board to host mode. This is required to ensure the
controller is initialized in the right mode if the kernel is build
with USB gadget support.

In case the optional dr_mode property isn't set in the dwc3 nodes the
the controller will go into OTG mode if both USB host and USB gadget
functionality are enabled in the kernel configuration. Unfortunately
this results in USB not working on exynos5420-peach-pit and
exynos5800-peach-pi with such a kernel configuration unless manually
change the mode. To resolve that explicitly configure the dual role
mode as host.
