early init: fix error handling when opening /dev/console
The comment says "this should never fail", but it definitely can fail
when you have odd initial boot filesystems, or kernel configurations.
So get the error handling right: filp_open() returns an error pointer.

breaks boot of many other platforms (e.g. OMAP or i.MX6) if
CONFIG_ARCH_BCM2835 is enabled in addition to some multiplatform
config (e.g. omap2plus_defconfig). The symptom is that the OMAP
based board does not show any activity beyond "Starting Kernel ..."

Reverting the mentioned commit makes it work again.

Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski:
"This small series replaces all in-kernel calls to the
userspace-focused ksys_mount() and ksys_dup() with calls to
kernel-centric functions:
For each replacement of ksys_mount() with do_mount(), one needs to
verify that the first and third parameter (char *dev_name, char *type)
are strings allocated in kernelspace and that the fifth parameter
(void *data) is either NULL or refers to a full page (only occurence
in init/do_mounts.c::do_mount_root()). The second and fourth
parameters (char *dir_name, unsigned long flags) are passed by
ksys_mount() to do_mount() unchanged, and therefore do not require
particular care.
Moreover, instead of pretending to be userspace, the opening of
/dev/console as stdin/stdout/stderr can be implemented using in-kernel
functions as well. Thereby, ksys_dup() can be removed for good"
[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"
case, but it at least removes _some_ of the users of "treat kernel
pointers as user pointers for our magical init sequence".
One day we'll hopefully be rid of it all, and can initialize our
init_thread addr_limit to USER_DS. - Linus ]

Pull FIELD_SIZEOF conversion from Kees Cook:
"A mostly mechanical treewide conversion from FIELD_SIZEOF() to
sizeof_field(). This avoids the redundancy of having 2 macros
(actually 3) doing the same thing, and consolidates on sizeof_field().
While "field" is not an accurate name, it is the common name used in
the kernel, and doesn't result in any unintended innuendo.
As there are still users of FIELD_SIZEOF() in -next, I will clean up
those during this coming development cycle and send the final old
macro removal patch at that time"

Fixes for omap variants for v5.5-rc1 cycle
This series of changes contains fixes for issues recently noticed:
- The ti-sysc interconnect target module driver needs fixes for
mstandby quirk handling and reset delay
- We need to configure am335x-sancloud-bbe to use rgmii-id mode because of
the phy changes done earlier
- NET_SWITCHDEV is no longer selected in Kconfig but a dependency and we
must enable CONFIG_NET_SWITCHDEV to have TI_CPSW_SWITCHDEV
- We are still relying on DEBUG_FS at least for PM configuration, let's
add it back

recent changes to use generic panels

if Linux had parsed and populated a devicetree.
However, the check for that (of_have_populated_dt()) can change after

when devicetree unittests are enabled. This causes an unmatched

This prevents a potential scenario that existing VA that was mmaped by

The IDE driver creates some passthru requests which never get

"Fixes for AFS plus one patch to make debugging easier:
- Fix how addresses are matched to server records. This is currently
incorrect which means cache invalidation callbacks from the server
don't necessarily get delivered correctly. This causes stale data
and metadata to be seen under some circumstances.
- Make the dynamic root superblock R/W so that rpm/dnf can reapply
the SELinux label to it when upgrading the Fedora filesystem-afs
package. If the filesystem is R/O, this fails and the upgrade
fails.
It might be better in future to allow setxattr from an LSM to
bypass the R/O protections, if only for pseudo-filesystems.
- Fix the parsing of mountpoint strings. The mountpoint object has to
have a terminal dot, whereas the source/device string passed to
mount should not. This confuses type-forcing suffix detection
leading to the wrong volume variant being mounted.
- Make lookups in the dynamic root superblock for creation events
(such as mkdir) fail with EOPNOTSUPP rather than something like
EEXIST. The dynamic root only allows implicit creation by the
->lookup() method - and only if the target cell exists.
- Fix the looking up of an AFS superblock to include the cell in the
matching key - otherwise all volumes with the same ID number are
treated as the same thing, irrespective of which cell they're in.
- Show the volume name of each volume in the volume records displayed
in /proc/net/afs/<cell>/volumes. This proved useful in debugging as
it provides a way to map the volume IDs to names, where the names
are what appear in /proc/mounts"
