* move ata_eh_analyze_ncq_error() and ata_eh_read_log_10h() to
libata-sata.c
* add static inline for ata_eh_analyze_ncq_error() for
CONFIG_SATA_HOST=n case (link->sactive is non-zero only if
NCQ commands are actually queued so empty function body is
sufficient)

It's currently the amba driver's responsibility to initialize the pointer,
dma_parms, for its corresponding struct device. The benefit with this
approach allows us to avoid the initialization and to not waste memory for
the struct device_dma_parameters, as this can be decided on a case by case
basis.
However, it has turned out that this approach is not very practical. Not
only does it lead to open coding, but also to real errors. In principle
callers of dma_set_max_seg_size() doesn't check the error code, but just
assumes it succeeds.
For these reasons, let's do the initialization from the common amba bus at
the device registration point. This also follows the way the PCI devices
are being managed, see pci_device_add().

Drop legacy platform data for omaps for v5.7
This series of changes continues dropping legacy platform data for
omaps by updating devices to probe with ti-sysc interconnect target
module driver:
- Update omap4, omap5, am437x, and dra7 display subsystem (DSS)
to probe with device tree data only
- Update am335x, am437x and dra7 to probe EDMA to probe with
device tree data only
- Drop legacy platform data for am335x and am437x PRUSS as the
current code just keeps the devices in reset
- Drop legacy platform data for omap4 DSP and IPU as the current
code just keeps the devices in reset
- Configure am437x and dra7 PRU-ICSS to probe with device tree
data
For the dropped omap4 DSP and IPU platform data, there will be patches
coming later on to configure the accelerators using the omap remoteproc
bindings so hopefully folks can actually use these devices eventually.

The error path for sanitize operations that completes with -ETIMEDOUT, is
tightly coupled with the internal request handling code of the core. More
precisely, mmc_wait_for_req_done() checks for specific sanitize errors.
This is not only inefficient as it affects all types of requests, but also
hackish.
Therefore, let's improve the behaviour by moving the error path out of the
mmc core. To do that, retuning needs to be held while running the sanitize
operation.
Moreover, to avoid exporting unnecessary symbols to the mmc block module,
let's move the code into the mmc_ops.c file. While updating the actual
code, let's also take the opportunity to clean up some of the mess around
it.

Introduce generic support for handling kernel panics in remoteproc
drivers, in order to allow operations needed for aiding in post mortem
system debugging, such as flushing caches etc.
The function can return a number of milliseconds needed by the remote to

returning from the panic handler.

Now that remoteproc can load an elf64, coredump elf class should be
the same as the loaded elf class. In order to do that, add a
elf_class field to rproc with default values. If an elf is loaded
successfully, this field will be updated with the loaded elf class.
Then, the coredump core code has been modified to use the generic elf
macro in order to create an elf file with correct class.

At present, on Power systems with Protected Execution Facility
hardware and an ultravisor, a KVM guest can transition to being a
secure guest at will. Userspace (QEMU) has no way of knowing
whether a host system is capable of running secure guests. This
will present a problem in future when the ultravisor is capable of
migrating secure guests from one host to another, because
virtualization management software will have no way to ensure that
secure guests only run in domains where all of the hosts can
support secure guests.
This adds a VM capability which has two functions: (a) userspace
can query it to find out whether the host can support secure guests,
and (b) userspace can enable it for a guest, which allows that
guest to become a secure guest. If userspace does not enable it,
KVM will return an error when the ultravisor does the hypercall
that indicates that the guest is starting to transition to a
secure guest. The ultravisor will then abort the transition and
the guest will terminate.

Report event FAN_DIR_MODIFY with name in a variable length record similar
to how fid's are reported. With name info reporting implemented, setting
FAN_DIR_MODIFY in mark mask is now allowed.
When events are reported with name, the reported fid identifies the
directory and the name follows the fid. The info record type for this
event info is FAN_EVENT_INFO_TYPE_DFID_NAME.
For now, all reported events have at most one info record which is
either FAN_EVENT_INFO_TYPE_FID or FAN_EVENT_INFO_TYPE_DFID_NAME (for
FAN_DIR_MODIFY). Later on, events "on child" will report both records.
There are several ways that an application can use this information:
1. When watching a single directory, the name is always relative to
the watched directory, so application need to fstatat(2) the name
relative to the watched directory.
2. When watching a set of directories, the application could keep a map
of dirfd for all watched directories and hash the map by fid obtained
with name_to_handle_at(2). When getting a name event, the fid in the
event info could be used to lookup the base dirfd in the map and then
call fstatat(2) with that dirfd.
3. When watching a filesystem (FAN_MARK_FILESYSTEM) or a large set of
directories, the application could use open_by_handle_at(2) with the fid
in event info to obtain dirfd for the directory where event happened and
call fstatat(2) with this dirfd.
The last option scales better for a large number of watched directories.
The first two options may be available in the future also for non
privileged fanotify watchers, because open_by_handle_at(2) requires
the CAP_DAC_READ_SEARCH capability.

SPI NOR core changes:
- move all the manufacturer specific quirks/code out of the core,
to make the core logic more readable and thus ease maintenance.
- move the SFDP logic out of the core, it provides a better
separation between the SFDP parsing and core logic.
- trim what is exposed in spi-nor.h. The SPI NOR controllers drivers
must not be able to use structures that are meant just for the
SPI NOR core.
- use the spi-mem direct mapping API to let advanced controllers
optimize the read/write operations when they support direct mapping.
- add generic formula for the Status Register block protection
handling. It fixes some long standing locking limitations and eases
the addition of the 4bit block protection support.
- add block protection support for flashes with 4 block protection
bits in the Status Register.
SPI NOR controller drivers changes:
- the mtk-quadspi driver is replaced by the new spi-mem
spi-mtk-nor driver. Merge tag 'mtk-mtd-spi-move' into spi-nor/next
to avoid conflicts.

To avoid a direct dependency with tc actions from netfilter, wrap the
redirect bits around CONFIG_NET_REDIRECT and move helpers to
include/linux/skbuff.h. Turn on this toggle from the ifb driver, the
only existing client of these bits in the tree.
This patch adds skb_set_redirected() that sets on the redirected bit
on the skbuff, it specifies if the packet was redirect from ingress
and resets the timestamp (timestamp reset was originally missing in the
netfilter bugfix).
