Commit fd73403a4862 ("dt-bindings: arm: Add SMP enable-method for
Milbeaut") added support for a new cpu enable-method, but did so using
tabulations to ident. This is however invalid in the syntax, and resulted
in a failure when trying to use that schemas for validation.
Use spaces instead of tabs to indent to fix this.

The output of the PSI files show a bunch of numbers with no unit. The
psi.txt documentation file also does not indicate what units are used.
One can only find out by looking at the source code. The units are
percentage for the averages and useconds for the total. Make the
information easier to find by documenting the units in psi.txt.

For very short input data (0 - 1 bytes), lzo-rle was not behaving
correctly. Fix this behaviour and update documentation accordingly.
For zero-length input, lzo v0 outputs an end-of-stream marker only,
which was misinterpreted by lzo-rle as a bitstream version number.
Ensure bitstream versions > 0 require a minimum stream length of 5.
Also fixes a bug in handling the tail for very short inputs when a
bitstream version is present.

The series to add memcg accounting to KVM allocations[1] states:
There are many KVM kernel memory allocations which are tied to the
life of the VM process and should be charged to the VM process's
cgroup.
While it is correct to account KVM kernel allocations to the cgroup of
the process that created the VM, it's technically incorrect to state
that the KVM kernel memory allocations are tied to the life of the VM
process. This is because the VM itself, i.e. struct kvm, is not tied to
the life of the process which created it, rather it is tied to the life
of its associated file descriptor. In other words, kvm_destroy_vm() is
not invoked until fput() decrements its associated file's refcount to
zero. A simple example is to fork() in Qemu and have the child sleep
indefinitely; kvm_destroy_vm() isn't called until Qemu closes its file
descriptor *and* the rogue child is killed.
The allocations are guaranteed to be *accounted* to the process which
created the VM, but only because KVM's per-{VM,vCPU} ioctls reject the
ioctl() with -EIO if kvm->mm != current->mm. I.e. the child can keep
the VM "alive" but can't do anything useful with its reference.
Note that because 'struct kvm' also holds a reference to the mm_struct
of its owner, the above behavior also applies to userspace allocations.
Given that mucking with a VM's file descriptor can lead to subtle and
undesirable behavior, e.g. memcg charges persisting after a VM is shut
down, explicitly document a VM's lifecycle and its impact on the VM's
resources.
Alternatively, KVM could aggressively free resources when the creating
process exits, e.g. via mmu_notifier->release(). However, mmu_notifier
isn't guaranteed to be available, and freeing resources when the creator
exits is likely to be error prone and fragile as KVM would need to
ensure that it only freed resources that are truly out of reach. In
practice, the existing behavior shouldn't be problematic as a properly
configured system will prevent a child process from being moved out of
the appropriate cgroup hierarchy, i.e. prevent hiding the process from
the OOM killer, and will prevent an unprivileged user from being able to
to hold a reference to struct kvm via another method, e.g. debugfs.

KVM's API requires thats ioctls must be issued from the same process
that created the VM. In other words, userspace can play games with a
VM's file descriptors, e.g. fork(), SCM_RIGHTS, etc..., but only the
creator can do anything useful. Explicitly reject device ioctls that
are issued by a process other than the VM's creator, and update KVM's
API documentation to extend its requirements to device ioctls.

Per Paolo[1], instantiating multiple VMs in a single process is legal;
but this conflicts with KVM's API documentation, which states:
The only supported use is one virtual machine per process, and one
vcpu per thread.
However, an earlier section in the documentation states:
Only run VM ioctls from the same process (address space) that was used
to create the VM.
and:
Only run vcpu ioctls from the same thread that was used to create the
vcpu.
This suggests that the conflicting documentation is simply an incorrect
ordering of of words, i.e. what's really meant is that a virtual machine
can't be shared across multiple processes and a vCPU can't be shared
across multiple threads.
Tweak the blurb on issuing ioctls to use a more assertive tone, and
rewrite the "supported use" sentence to reference said blurb instead of
poorly restating it in different terms.
Opportunistically add missing punctuation.

[Improve notes on asynchronous ioctl]

The cr4_pae flag is a bit of a misnomer, its purpose is really to track
whether the guest PTE that is being shadowed is a 4-byte entry or an
8-byte entry. Prior to supporting nested EPT, the size of the gpte was
reflected purely by CR4.PAE. KVM fudged things a bit for direct sptes,
but it was mostly harmless since the size of the gpte never mattered.
Now that a spte may be tracking an indirect EPT entry, relying on
CR4.PAE is wrong and ill-named.
For direct shadow pages, force the gpte_size to '1' as they are always
8-byte entries; EPT entries can only be 8-bytes and KVM always uses
8-byte entries for NPT and its identity map (when running with EPT but
not unrestricted guest).
Likewise, nested EPT entries are always 8-bytes. Nested EPT presents a
unique scenario as the size of the entries are not dictated by CR4.PAE,
but neither is the shadow page a direct map. To handle this scenario,
set cr0_wp=1 and smap_andnot_wp=1, an otherwise impossible combination,
to denote a nested EPT shadow page. Use the information to avoid
incorrectly zapping an unsync'd indirect page in __kvm_sync_page().
Providing a consistent and accurate gpte_size fixes a bug reported by
Vitaly where fast_cr3_switch() always fails when switching from L2 to
L1 as kvm_mmu_get_page() would force role.cr4_pae=0 for direct pages,
whereas kvm_calc_mmu_role_common() would set it according to CR4.PAE.

In the example, the phy at phy@0 is clashing with
the switch0@0 at the same address. Usually, the switches
are accessible through pseudo PHYs which in case of the
qca8k are located at 0x10 - 0x18.

The sysfs files are replaced by the batadv generic netlink family. The old
sysfs configuration interface was frowned upon by other kernel developers.
But the files cannot be removed immediately because userspace tools might
still depend on it. Instead schedule for its removal in 2021.

The sysfs files will be marked as deprecated in the near future. They
are already replaced by the batadv generic netlink family. The
documentation should not advertise its usage anymore and instead
promote the generic netlink family and a userspace tool to access it.

fib_trie implementation calls synchronize_rcu when a certain amount of
pages are dirty from freed entries. The number of pages was determined
experimentally in 2009 (commit c3059477fce2d).
At the current setting, synchronize_rcu is called often -- 51 times in a
second in one test with an average of an 8 msec delay adding a fib entry.
The total impact is a lot of slow down modifying the fib. This is seen
in the output of 'time' - the difference between real time and sys+user.
For example, using 720,022 single path routes and 'ip -batch'[1]:
$ time ./ip -batch ipv4/routes-1-hops
real 0m14.214s
user 0m2.513s
sys 0m6.783s
So roughly 35% of the actual time to install the routes is from the ip
command getting scheduled out, most notably due to synchronize_rcu (this
is observed using 'perf sched timehist').
This patch makes the amount of dirty memory configurable between 64k where
the synchronize_rcu is called often (small, low end systems that are memory
sensitive) to 64M where synchronize_rcu is called rarely during a large
FIB change (for high end systems with lots of memory). The default is 512kB
which corresponds to the current setting of 128 pages with a 4kB page size.
As an example, at 16MB the worst interval shows 4 calls to synchronize_rcu
in a second blocking for up to 30 msec in a single instance, and a total
of almost 100 msec across the 4 calls in the second. The trade off is
allowing FIB entries to consume more memory in a given time window but
but with much better fib insertion rates (~30% increase in prefixes/sec).
With this patch and net.ipv4.fib_sync_mem set to 16MB, the same batch
file runs in:
$ time ./ip -batch ipv4/routes-1-hops
real 0m9.692s
user 0m2.491s
sys 0m6.769s
So the dead time is reduced to about 1/2 second or <5% of the real time.
[1] 'ip' modified to not request ACK messages which improves route
insertion times by about 20%

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree:
1) Remove a direct dependency with IPv6 introduced by the
sip_external_media feature, from Alin Nastac.
2) Fix bogus ENOENT when removing interval elements from set.
3) Set transport_header from br_netfilter to mimic the stack
behaviour, this partially fixes a checksum validation bug
from the SCTP connection tracking, from Xin Long.
4) Fix undefined reference to symbol in xt_TEE, due to missing
Kconfig dependencies, from Arnd Bergmann.
5) Check for NULL in skb_header_pointer() calls in ip6t_shr,
from Kangjie Lu.
6) Fix bogus EBUSY when removing an existing conntrack helper from
a transaction.
7) Fix module autoload of the redirect extension.
8) Remove duplicated transition in flowtable diagram in the existing
documentation.
9) Missing .release_ops call from error path in newrule() which
results module refcount leak, from Taehee Yoo.
