This reverts commit
644bda6f3460 ("dm table: fall back to getting device using name_to_dev_t()")
dm_get_dev_t() is just used to convert an arbitrary 'path' string
into a dev_t. It doesn't presume that the device is present; that
check will be done later, as the only caller is dm_get_device(),
which does a dm_get_table_device() later on, which will properly
open the device.
So if the path string already _is_ in major:minor representation
we can convert it directly, avoiding a recursion into the filesystem
to lookup the block device.
This avoids a hang in multipath_message() when the filesystem is
inaccessible.

In commit d68b29584c25 ("dm crypt: use GFP_ATOMIC when allocating
crypto requests from softirq") code was incorrectly copy and pasted
from crypt_alloc_req_skcipher()'s crypto request allocation code to
crypt_alloc_req_aead(). It is OK from runtime perspective as both
simple encryption request pointer and AEAD request pointer are part of
a union, but may confuse code reviewers.

Otherwise a malicious user could (ab)use the "recalculate" feature
that makes dm-integrity calculate the checksums in the background
while the device is already usable. When the system restarts before all
checksums have been calculated, the calculation continues where it was
interrupted even if the recalculate feature is not requested the next
time the dm device is set up.
Disable recalculating if we use internal_hash or journal_hash with a
key (e.g. HMAC) and we don't have the "legacy_recalculate" flag.
This may break activation of a volume, created by an older kernel,
that is not yet fully recalculated -- if this happens, the user should
add the "legacy_recalculate" flag to constructor parameters.

The OMAP driver may leverage software BCH logic to locate errors while
using its own hardware to detect the presence of errors. This is
achieved with a "mixed" mode which initializes manually the software
BCH internal logic while providing its own OOB layout.
The issue here comes from the fact that the BCH driver has been
updated to only use generic NAND objects, and no longer depend on raw
NAND structures as it is usable from SPI-NAND as well. However, at the
end of the BCH context initialization, the driver checks the validity
of the OOB layout. At this stage, the raw NAND fields have not been
populated yet while being used by the layout helpers, leading to an
invalid layout.
The chosen solution here is to include the BCH structure definition
and to refer to the BCH fields directly (de-referenced as a const
pointer here) to know as early as possible the number of steps and ECC
bytes which have been chosen.
Note: I don't know which commit exactly triggered the error, but the
entire migration to a generic BCH driver got merged in one go, so this
should not be a problem for stable backports.

Set the acpi_device pointer which acpi_bus_get_device() returns-by-
reference to NULL on errors.
We've recently had 2 cases where callers of acpi_bus_get_device()
did not properly error check the return value, so set the returned-
by-reference acpi_device pointer to NULL, because at least some
callers of acpi_bus_get_device() expect that to be done on errors.
[ rjw: This issue was exposed by commit 71da201f38df ("ACPI: scan:
Defer enumeration of devices with _DEP lists") which caused it to
be much more likely to occur on some systems, but the real defect
had been introduced by an earlier commit. ]

====================
linux-can-fixes-for-5.11-20210120
All three patches are by Vincent Mailhol and fix a potential use after free bug
in the CAN device infrastructure, the vxcan driver, and the peak_usk driver. In
the TX-path the skb is used to read from after it was passed to the networking
stack with netif_rx_ni().

Multicast entries in the MAC table use the high bits of the MAC
address to encode the ports that should get the packets. But this port
mask does not work for the CPU port, to receive these packets on the
CPU port the MAC_CPU_COPY flag must be set.
Because of this IPv6 was effectively not working because neighbor
solicitations were never received. This was not apparent before commit
9403c158 (net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb
entries) as the IPv6 entries were broken so all incoming IPv6
multicast was then treated as unknown and flooded on all ports.
To fix this problem rework the ocelot_mact_learn() to set the
MAC_CPU_COPY flag when a multicast entry that target the CPU port is
added. For this we have to read back the ports endcoded in the pseudo
MAC address by the caller. It is not a very nice design but that avoid
changing the callers and should make backporting easier.

sh_eth_close() does a synchronous power down of the device before
marking it closed. Revert the order, to make sure the device is never
marked opened while suspended.
While at it, use pm_runtime_put() instead of pm_runtime_put_sync(), as
there is no reason to do a synchronous power down.

As of commit e2f016cf775129c0 ("net: phy: add a shutdown procedure"),
system reboot calls phy_disable_interrupts() during shutdown. As this
happens unconditionally, the PHY registers may be accessed while the
device is suspended, causing undefined behavior, which may crash the
system.
Fix this by wrapping the PHY bitbang accessors in the sh_eth driver by
wrappers that take care of Runtime PM, to resume the device when needed.
