This reverts commit 6ff646b2ce.
Your maintainer committed a major braino in the rmap code by adding the
attr fork, bmbt, and unwritten extent usage bits into rmap record key
comparisons. While XFS uses the usage bits *in the rmap records* for
cross-referencing metadata in xfs_scrub and xfs_repair, it only needs
the owner and offset information to distinguish between reverse mappings
of the same physical extent into the data fork of a file at multiple
offsets. The other bits are not important for key comparisons for index
lookups, and never have been.
Eric Sandeen reports that this causes regressions in generic/299, so
undo this patch before it does more damage.

6ae08ae3de ("bpf: Add probe_read_{user, kernel} and probe_read_{user,

bpf_probe_read_user_str() would potentially copy a few extra bytes after

This issue is particularly nefarious when strings are used as map keys,
as seemingly identical strings can occupy multiple entries in a map.
This patchset fixes the issue and introduces a selftest to prevent
future regressions.

do_strncpy_from_user() may copy some extra bytes after the NUL
terminator into the destination buffer. This usually does not matter for
normal string operations. However, when BPF programs key BPF maps with
strings, this matters a lot.
A BPF program may read strings from user memory by calling the
bpf_probe_read_user_str() helper which eventually calls
do_strncpy_from_user(). The program can then key a map with the
destination buffer. BPF map keys are fixed-width and string-agnostic,
meaning that map keys are treated as a set of bytes.
The issue is when do_strncpy_from_user() overcopies bytes after the NUL
terminator, it can result in seemingly identical strings occupying
multiple slots in a BPF map. This behavior is subtle and totally
unexpected by the user.
This commit masks out the bytes following the NUL while preserving
long-sized stride in the fast path.

Pull powerpc fixes from Michael Ellerman:
"Fixes for CVE-2020-4788.
From Daniel's cover letter:
IBM Power9 processors can speculatively operate on data in the L1
cache before it has been completely validated, via a way-prediction
mechanism. It is not possible for an attacker to determine the
contents of impermissible memory using this method, since these
systems implement a combination of hardware and software security
measures to prevent scenarios where protected data could be leaked.
However these measures don't address the scenario where an attacker
induces the operating system to speculatively execute instructions
using data that the attacker controls. This can be used for example to
speculatively bypass "kernel user access prevention" techniques, as
discovered by Anthony Steinhauser of Google's Safeside Project. This
is not an attack by itself, but there is a possibility it could be
used in conjunction with side-channels or other weaknesses in the
privileged code to construct an attack.
This issue can be mitigated by flushing the L1 cache between privilege
boundaries of concern.
This patch series flushes the L1 cache on kernel entry (patch 2) and
after the kernel performs any user accesses (patch 3). It also adds a
self-test and performs some related cleanups"

The simplest fix, explained in detail in Lukas' commit message, is to
move to a devm_ function for allocation of the controller and hence
driver data in order to push the free of that after anything tries to
reference the driver data in the remove path. This results in a
relatively large diff due to the addition of a new function but isn't

net/smc: fixes 2020-11-18
Patch 1 fixes the matching of link groups because with SMC-Dv2 the vlanid
should no longer be part of this matching. Patch 2 removes a sparse message.

Sparse complaints 3 times about:
net/smc/smc_ib.c:203:52: warning: incorrect type in argument 1 (different address spaces)
net/smc/smc_ib.c:203:52: expected struct net_device const *dev
net/smc/smc_ib.c:203:52: got struct net_device [noderef] __rcu *const ndev
Fix that by using the existing and validated ndev variable instead of
accessing attr->ndev directly.

With the multi-subnet support of SMC-Dv2 the match for existing link
groups should not include the vlanid of the network device.
Set ini->smcd_version accordingly before the call to smc_conn_create()
and use this value in smc_conn_create() to skip the vlanid check.

ASoC: Fixes for v5.11
A collection of driver specific fixes, mostly for x86 systems (or CODECs
used mostly on x86) and all for relatively minor issues, the biggest one
being fixing S24_LE format on Keem Bay systems.
Pull regulator fixes from Mark Brown:
"Mostly core fixes here, one set from Michał Mirosław which cleans up
some issues introduced as part of the coupled regulators work, one
memory leak during probe and two due to regulators which have an input
supply name and regulator name which are identical, which is very
unusual.
There's also a fix for our handling of the similarly unusual case
where we can't determine if a regulator is enabled during boot"

Netfilter is depending on ipv6 symbol ipv6_frag_thdr_truncated. This
dependency is forcing IPV6=y.
Remove this dependency by moving ipv6_frag_thdr_truncated out of ipv6. This
is the same solution as used with a similar issues: Referring to

The code change for switching to non-atomic mode brought the
unexpected mutex deadlock in get_msg(). It converted the spinlock
with the existing mutex, but there were calls with the already holding
the mutex. Since the only place that needs the extra lock is the code
path from snd_mixart_send_msg(), remove the mutex lock in get_msg()
and apply in the caller side for fixing the mutex deadlock.
