We want to change swap_state to wait indefinitely, but to do this
swap_state should wait interruptibly. This requires propagating

Add the new ORC unwinder which is enabled by CONFIG_ORC_UNWINDER=y.
It plugs into the existing x86 unwinder framework.
It relies on objtool to generate the needed .orc_unwind and
.orc_unwind_ip sections.
For more details on why ORC is used instead of DWARF, see
Documentation/x86/orc-unwinder.txt - but the short version is
that it's a simplified, fundamentally more robust debugninfo
data structure, which also allows up to two orders of magnitude
faster lookups than the DWARF unwinder - which matters to
profiling workloads like perf.
Thanks to Andy Lutomirski for the performance improvement ideas:
splitting the ORC unwind table into two parallel arrays and creating a
fast lookup table to search a subset of the unwind table.

drop VPFE_CMD_S_CCDC_RAW_PARAMS ioctl from dm355/dm644x following reasons:
- This ioctl was never in public api and was only defined in kernel header.
- The function set_params constantly mixes up pointers and phys_addr_t
numbers.
- This is part of a 'VPFE_CMD_S_CCDC_RAW_PARAMS' ioctl command that is
described as an 'experimental ioctl that will change in future kernels'.
- The code to allocate the table never gets called after we copy_from_user
the user input over the kernel settings, and then compare them
for inequality.
- We then go on to use an address provided by user space as both the
__user pointer for input and pass it through phys_to_virt to come up
with a kernel pointer to copy the data to. This looks like a trivially
exploitable root hole.

The policy->transition_latency field is used for multiple purposes
today and its not straight forward at all. This is how it is used:
A. Set the correct transition_latency value.
B. Set it to CPUFREQ_ETERNAL because:
1. We don't want automatic dynamic switching (with
ondemand/conservative) to happen at all.
2. We don't know the transition latency.
This patch handles the B.1. case in a more readable way. A new flag for
the cpufreq drivers is added to disallow use of cpufreq governors which
have dynamic_switching flag set.
All the current cpufreq drivers which are setting transition_latency
unconditionally to CPUFREQ_ETERNAL are updated to use it. They don't
need to set transition_latency anymore.
There shouldn't be any functional change after this patch.

There is no limitation in the ondemand or conservative governors which
disallow the transition_latency to be greater than 10 ms.
The max_transition_latency field is rather used to disallow automatic
dynamic frequency switching for platforms which didn't wanted these
governors to run.
Replace max_transition_latency with a boolean (dynamic_switching) and
check for transition_latency == CPUFREQ_ETERNAL along with that. This
makes it pretty straight forward to read/understand now.

RCU callbacks must be migrated away from an outgoing CPU, and this is
done near the end of the CPU-hotplug operation, after the outgoing CPU is
long gone. Unfortunately, this means that other CPU-hotplug callbacks
can execute while the outgoing CPU's callbacks are still immobilized
on the long-gone CPU's callback lists. If any of these CPU-hotplug
callbacks must wait, either directly or indirectly, for the invocation
of any of the immobilized RCU callbacks, the system will hang.
This commit avoids such hangs by migrating the callbacks away from the
outgoing CPU immediately upon its departure, shortly after the return
from __cpu_die() in takedown_cpu(). Thus, RCU is able to advance these
callbacks and invoke them, which allows all the after-the-fact CPU-hotplug
callbacks to wait on these RCU callbacks without risk of a hang.
While in the neighborhood, this commit also moves rcu_send_cbs_to_orphanage()
and rcu_adopt_orphan_cbs() under a pre-existing #ifdef to avoid including
dead code on the one hand and to avoid define-without-use warnings on the
other hand.

5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be
ordered") automatically enabled ordered attribute for unbound
workqueues w/ max_active == 1. Because ordered workqueues reject
max_active and some attribute changes, this implicit ordered mode
broke cases where the user creates an unbound workqueue w/ max_active
== 1 and later explicitly changes the related attributes.
This patch distinguishes explicit and implicit ordered setting and
overrides from attribute changes if implict.

Paul Moore reported a SELinux/IP_PASSSEC regression
caused by missing skb->sp at recvmsg() time. We need to
preserve the skb head state to process the IP_CMSG_PASSSEC
cmsg.
With this commit we avoid releasing the skb head state in the
BH even if a secpath is attached to the current skb, and stores
the skb status (with/without head states) in the scratch area,
so that we can access it at skb deallocation time, without
incurring in cache-miss penalties.
This also avoids misusing the skb CB for ipv6 packets,
as introduced by the commit 0ddf3fb2c43d ("udp: preserve
skb->dst if required for IP options processing").
Clean a bit the scratch area helpers implementation, to
reduce the code differences between 32 and 64 bits build.

The FC-NVME spec hasn't locked down on the format string for TRADDR.
Currently the spec is lobbying for "nn-<16hexdigits>:pn-<16hexdigits>"
where the wwn's are hex values but not prefixed by 0x.
Most implementations so far expect a string format of
"nn-0x<16hexdigits>:pn-0x<16hexdigits>" to be used. The transport
uses the match_u64 parser which requires a leading 0x prefix to set
the base properly. If it's not there, a match will either fail or return
a base 10 value.
The resolution in T11 is pushing out. Therefore, to fix things now and
to cover any eventuality and any implementations already in the field,
this patch adds support for both formats.
The change consists of replacing the token matching routine with a
routine that validates the fixed string format, and then builds
a local copy of the hex name with a 0x prefix before calling
the system parser.
Note: the same parser routine exists in both the initiator and target
transports. Given this is about the only "shared" item, we chose to
replicate rather than create an interdendency on some shared code.

kvm_pmu_overflow_set() is called from perf's interrupt handler,
making the call of kvm_vgic_inject_irq() from it introduced with
"KVM: arm/arm64: PMU: remove request-less vcpu kick" a really bad
idea, as it's quite easy to try and retake a lock that the
interrupted context is already holding. The fix is to use a vcpu
kick, leaving the interrupt injection to kvm_pmu_sync_hwstate(),
like it was doing before the refactoring. We don't just revert,
though, because before the kick was request-less, leaving the vcpu
exposed to the request-less vcpu kick race, and also because the
kick was used unnecessarily from register access handlers.

====================
rxrpc: Rearrange headers
Here's a pair of patches that rearrange some of the AF_RXRPC header files
that are outside of the net/rxrpc/ directory:
(1) The bits userspace need are moved to uapi/linux/rxrpc.h. [Should this
be af_rxrpc.h instead, I wonder - but there doesn't seem to be
precedent for that in the other net UAPI headers.]
(2) For the most part, the contents of rxrpc/packet.h are no longer used
outside of the AF_RXRPC module, so move them to net/rxrpc/protocol.h
with the exception of the standard abort codes which are exposed to
userspace when an abort occurs and the security index values which are
needed when constructing keys.

Strings used in event tracing need to be specially handled, for example,
being copied to the trace buffer instead of being pointed to by the trace
buffer. Although the TPS() macro can be used to "launder" pointed-to

Back in the dim distant past, the task_struct structure's RCU-related
fields optionally included those needed for CONFIG_RCU_BOOST, even in
CONFIG_PREEMPT_RCU builds. The INIT_TASK_RCU_TREE_PREEMPT() macro was
used to provide initializers for those optional CONFIG_RCU_BOOST fields.
However, the CONFIG_RCU_BOOST fields are now included unconditionally
in CONFIG_PREEMPT_RCU builds, so there is no longer any need fro the
INIT_TASK_RCU_TREE_PREEMPT() macro. This commit therefore removes it
in favor of initializing the ->rcu_blocked_node field directly in the
INIT_TASK_RCU_PREEMPT() macro.

Put the device interrupts disabling and enabling as well as
cpuidle_pause() and cpuidle_resume() called during the "noirq"
stages of system suspend into separate functions to allow the
core suspend-to-idle code to be optimized (later).
The only functional difference this makes is that debug facilities
and diagnostic tools will not include the above operations into the
"noirq" device suspend/resume duration measurements.

This adds a new NETDEV_UDP_TUNNEL_DROP_INFO event, similar to
NETDEV_UDP_TUNNEL_PUSH_INFO, to signal to un-offload ports.
This also adds udp_tunnel_drop_rx_port(), which calls
ndo_udp_tunnel_del.

This adds a new netdevice feature, so that the offloading of RX port for
UDP tunnels can be disabled by the administrator on some netdevices,
using the "rx-udp_tunnel-port-offload" feature in ethtool.
This feature is set for all devices that provide ndo_udp_tunnel_add.
