The ndo_start_xmit() method must not attempt to free the skb to transmit
when returning NETDEV_TX_BUSY. Therefore, make sure the
korina_send_packet() function returns NETDEV_TX_OK when it frees a packet.

We need the bits of _TIF_WORK_MASK to be contiguous in order to to use
this as an immediate argument to an AND instruction in entry.S.
We happened to change these bits in commits:
b5a5a01d8e9a ("arm64: uaccess: remove addr_limit_user_check()")
192caabd4dd9 ("arm64: add support for TIF_NOTIFY_SIGNAL")
which each worked in isolation, but the merge resolution in commit:
005b2a9dc819 ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block")
happened to make the bits non-contiguous.
Fix this by moving TIF_NOTIFY_SIGNAL to be bit 6, which is contiguous
with the rest of _TIF_WORK_MASK.
Otherwise, we'll get a build-time failure as below:
arch/arm64/kernel/entry.S: Assembler messages:
arch/arm64/kernel/entry.S:733: Error: immediate out of range at operand 3 -- `and x2,x19,#((1<<1)|(1<<0)|(1<<2)|(1<<3)|(1<<4)|(1<<5)|(1<<7))'

Pull IOMMU updates from Will Deacon:
"There's a good mixture of improvements to the core code and driver
changes across the board.
One thing worth pointing out is that this includes a quirk to work
around behaviour in the i915 driver (see 65f746e8285f ("iommu: Add
quirk for Intel graphic devices in map_sg")), which otherwise
interacts badly with the conversion of the intel IOMMU driver over to
the DMA-IOMMU APU but has being fixed properly in the DRM tree.
We'll revert the quirk later this cycle once we've confirmed that
things don't fall apart without it.
Summary:
- IOVA allocation optimisations and removal of unused code
- Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the
page-table of an IOMMU domain
- Support for changing the default domain type in sysfs
- Optimisation to the way in which identity-mapped regions are
created
- Driver updates:
* Arm SMMU updates, including continued work on Shared Virtual

The parent of an ib device is used to retrieve the PCI device
attributes. It turns out that there are possible cases when an ib device
has no parent set in the device structure, which may lead to page
faults when trying to access this memory.
Fix that by checking the parent pointer and consolidate the pci device
specific processing in a new function.

When we initialize nlmsghdr with no payload inside tipc_nl_compat_dumpit()
the parsing function returns -EINVAL. We fix it by making the parsing call
conditional.

Pull io_uring updates from Jens Axboe:
"Fairly light set of changes this time around, and mostly some bits
that were pushed out to 5.11 instead of 5.10, fixes/cleanups, and a
few features. In particular:
- Cleanups around iovec import (David Laight, Pavel)
- Add timeout support for io_uring_enter(2), which enables us to
clean up liburing and avoid a timeout sqe submission in the
completion path.
The big win here is that it allows setups that split SQ and CQ
handling into separate threads to avoid locking, as the CQ side
will no longer submit when timeouts are needed when waiting for
events (Hao Xu)
- Add support for socket shutdown, and renameat/unlinkat.
- SQPOLL cleanups and improvements (Xiaoguang Wang)
- Allow SQPOLL setups for CAP_SYS_NICE, and enable regular
(non-fixed) files to be used.
- Cancelation improvements (Pavel)

- IOPOLL related race fixes (Pavel)

Pull TIF_NOTIFY_SIGNAL updates from Jens Axboe:
"This sits on top of of the core entry/exit and x86 entry branch from
the tip tree, which contains the generic and x86 parts of this work.
Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL.
With that done, we can get rid of JOBCTL_TASK_WORK from task_work and
signal.c, and also remove a deadlock work-around in io_uring around
knowing that signal based task_work waking is invoked with the sighand
wait queue head lock.
The motivation for this work is to decouple signal notify based
task_work, of which io_uring is a heavy user of, from sighand. The
sighand lock becomes a huge contention point, particularly for
threaded workloads where it's shared between threads. Even outside of
threaded applications it's slower than it needs to be.
Roman Gershman <romger@amazon.com> reported that his networked
workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU
after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all
spent hammering on the sighand lock, showing 57% of the CPU time there
[1].
There are further cleanups possible on top of this. One example is
TIF_PATCH_PENDING, where a patch already exists to use
TIF_NOTIFY_SIGNAL instead. Hopefully this will also lead to more
consolidation, but the work stands on its own as well"

This series introduce the lockless version of netdev_notify_peers
and then apply it to the relevant drivers.
In v1, a more appropriate name __netdev_notify_peers is used;
netdev_notify_peers is converted to call the new helper.
In v2, patch 3 calls the new helper where notify variable used
to be set true.

There are some use cases for netdev_notify_peers in the context

call_netdevice_notifiers(NETDEV_NOTIFY_PEERS, dev);

After that, convert netdev_notify_peers to call the new helper.

DSA: tree 0 setup
To fix it, it is better to move access to MDIO register to the .irq_bus_sync_unlock
call back.

Pull audit updates from Paul Moore:
"A small set of audit patches for v5.11 with four patches in total and
only one of any real significance.
Richard's patch to trigger accompanying records causes the kernel to
emit additional related records when an audit event occurs; helping
provide some much needed context to events in the audit log. It is
also worth mentioning that this is a revised patch based on an earlier
attempt that had to be reverted in the v5.8 time frame.
Everything passes our test suite, and with no problems reported please
merge this for v5.11"
* tag 'audit-pr-20201214' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
audit: replace atomic_add_return()
audit: fix macros warnings
audit: trigger accompanying records when no rules present
audit: fix a kernel-doc markup
