DRA7xx/AM57xx SoCs have two IPU and up to two DSP processor subsystems
for offloading different computation algorithms. The IPU processor
subsystem contains dual-core ARM Cortex-M4 processors, and is very
similar to those on OMAP5. The DSP processor subsystem is based on
the TI's standard TMS320C66x DSP CorePac core.
Support has been added to the OMAP remoteproc driver through new
DRA7xx specific compatibles for properly probing and booting all
the different processor subsystem instances on DRA7xx/AM57xx
SoCs - IPU1, IPU2, DSP1 & DSP2. A build dependency with SOC_DRA7XX
is added to enable the driver to be built in DRA7xx-only configuration.
The DSP boot address programming needed enhancement for DRA7xx as the
boot register fields are different on DRA7 compared to OMAP4 and OMAP5
SoCs. The register on DRA7xx contains additional fields within the
register and the boot address bit-field is right-shifted by 10 bits.
The internal memory parsing logic has also been updated to compute
the device addresses for the L2 RAM for DSP devices using relative
addressing logic, and to parse two additional RAMs at L1 level - L1P
and L1D. This allows the remoteproc driver to support loading into
these regions for a small subset of firmware images requiring as
such. The most common usage would be to use the L1 programmable
RAMs as L1 Caches.
The firmware lookup logic also has to be adjusted for DRA7xx as
there are (can be) more than one instance of both the IPU and DSP
remote processors for the first time in OMAP4+ SoCs.

The reserved memory nodes are not assigned to platform devices by
default in the driver core to avoid the lookup for every platform
device and incur a penalty as the real users are expected to be
only a few devices.
OMAP remoteproc devices fall into the above category and the OMAP
remoteproc driver _requires_ specific CMA pools to be assigned
for each device at the moment to align on the location of the
vrings and vring buffers in the RTOS-side firmware images. So,
use the of_reserved_mem_device_init/release() API appropriately
to assign the corresponding reserved memory region to the OMAP
remoteproc device. Note that only one region per device is
allowed by the framework.

An implementation for the rproc ops .da_to_va() has been added
that provides the address translation between device addresses
to kernel virtual addresses for internal RAMs present on that
particular remote processor device. The implementation provides
the translations based on the addresses parsed and stored during
the probe.
This ops gets invoked by the exported rproc_da_to_va() function

The OMAP remoteproc driver has been enhanced to parse and store
the kernel mappings for different internal RAM memories that may
be present within each remote processor IP subsystem. Different
devices have varying memories present on current SoCs. The current
support handles the L2RAM for all IPU devices on OMAP4+ SoCs. The
DSPs on OMAP4/OMAP5 only have Unicaches and do not have any L1 or
L2 RAM memories.
IPUs are expected to have the L2RAM at a fixed device address of
0x20000000, based on the current limitations on Attribute MMU
configurations.
NOTE:
The current logic doesn't handle the parsing of memories for DRA7
remoteproc devices, and will be added alongside the DRA7 support.

The DSP remote processors on OMAP SoCs require a boot register to
be programmed with a boot address, and this boot address needs to
be on a 1KB boundary. The current code is simply masking the boot
address appropriately without performing any sanity checks before
releasing the resets. An unaligned boot address results in an
undefined execution behavior and can result in various bus errors
like MMU Faults or L3 NoC errors. Such errors are hard to debug and
can be easily avoided by adding a sanity check for the alignment
before booting a DSP remote processor.

OMAP4+ SoCs support device tree boot only. The OMAP remoteproc
driver is enhanced to support remoteproc devices created through
Device Tree, support for legacy platform devices has been
deprecated. The current DT support handles the IPU and DSP
processor subsystems on OMAP4 and OMAP5 SoCs.
The OMAP remoteproc driver relies on the ti-sysc, reset, and
syscon layers for performing clock, reset and boot vector
management (DSP remoteprocs only) of the devices, but some of
these are limited only to the machine-specific layers
in arch/arm. The dependency against control module API for boot
vector management of the DSP remoteprocs has now been removed
with added logic to parse the boot register from the DT node
and program it appropriately directly within the driver.
The OMAP remoteproc driver expects the firmware names to be
provided via device tree entries (firmware-name.) These are used
to load the proper firmware during boot of the remote processor.

Two places call rproc_trigger_recovery():
- rproc_crash_handler_work() sets rproc->state to CRASHED under
protection of the mutex, then calls it if recovery is not
disabled. This function is called in workqueue context when
scheduled in rproc_report_crash().
- rproc_recovery_write() calls it in two spots, both of which
the only call it if the rproc->state is CRASHED.
The mutex is taken right away in rproc_trigger_recovery(). However,
by the time the mutex is acquired, something else might have changed
rproc->state to something other than CRASHED.
The work that follows that is only appropriate for a remoteproc in
CRASHED state. So check the state after acquiring the mutex, and
only proceed with the recovery work if the remoteproc is still in
CRASHED state.
Delay reporting that recovering has begun until after we hold the
mutex and we know the remote processor is in CRASHED state.

Pull new zonefs file system from Damien Le Moal:
"Zonefs is a very simple file system exposing each zone of a zoned
block device as a file.
Unlike a regular file system with native zoned block device support
(e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
sequential write constraint of zoned block devices to the user. As a
result, zonefs is not a POSIX compliant file system. Its goal is to
simplify the implementation of zoned block devices support in
applications by replacing raw block device file accesses with a richer
file based API, avoiding relying on direct block device file ioctls
which may be more obscure to developers.
One example of this approach is the implementation of LSM
(log-structured merge) tree structures (such as used in RocksDB and
LevelDB) on zoned block devices by allowing SSTables to be stored in a
zone file similarly to a regular file system rather than as a range of
sectors of a zoned device. The introduction of the higher level
construct "one file is one zone" can help reducing the amount of
changes needed in the application while at the same time allowing the
use of zoned block devices with various programming languages other
than C.
Zonefs IO management implementation uses the new iomap generic code.
Zonefs has been successfully tested using a functional test suite
(available with zonefs userland format tool on github) and a prototype
implementation of LevelDB on top of zonefs"

"A set of fixes for X86:
- Ensure that the PIT is set up when the local APIC is disable or
configured in legacy mode. This is caused by an ordering issue
introduced in the recent changes which skip PIT initialization when
the TSC and APIC frequencies are already known.
- Handle malformed SRAT tables during early ACPI parsing which caused
an infinite loop anda boot hang.
- Fix a long standing race in the affinity setting code which affects
PCI devices with non-maskable MSI interrupts. The problem is caused
by the non-atomic writes of the MSI address (destination APIC id)
and data (vector) fields which the device uses to construct the MSI
message. The non-atomic writes are mandated by PCI.
If both fields change and the device raises an interrupt after
writing address and before writing data, then the MSI block
constructs a inconsistent message which causes interrupts to be
lost and subsequent malfunction of the device.
The fix is to redirect the interrupt to the new vector on the
current CPU first and then switch it over to the new target CPU.
This allows to observe an eventually raised interrupt in the
transitional stage (old CPU, new vector) to be observed in the APIC
IRR and retriggered on the new target CPU and the new vector.
The potential spurious interrupts caused by this are harmless and
can in the worst case expose a buggy driver (all handlers have to
be able to deal with spurious interrupts as they can and do happen
for various reasons).
- Add the missing suspend/resume mechanism for the HYPERV hypercall

VirtualBox hosts can share folders with guests, this commit adds a
VFS driver implementing the Linux-guest side of this, allowing folders
exported by the host to be mounted under Linux.
This driver depends on the guest <-> host IPC functions exported by
the vboxguest driver.

Pull powerpc fixes from Michael Ellerman:
- Fix an existing bug in our user access handling, exposed by one of
the bug fixes we merged this cycle.
- A fix for a boot hang on 32-bit with CONFIG_TRACE_IRQFLAGS and the
recently added CONFIG_VMAP_STACK.
Thanks to: Christophe Leroy, Guenter Roeck.

This is a merge error on my part - the driver was merged into mainline
by commit c5951e7c8e ("Merge tag 'mips_5.6' of git://../mips/linux")
over a week ago, but nobody apparently noticed that it didn't actually
build due to still having a reference to the devm_ioremap_nocache()
function, removed a few days earlier through commit 6a1000bd27 ("Merge
tag 'ioremap-5.6' of git://../ioremap").
Apparently this didn't get any build testing anywhere. Not perhaps all
that surprising: it's restricted to 64-bit MIPS only, and only with the
new SGI_MFD_IOC3 support enabled.
I only noticed because the ioremap conflicts in the ARM SoC driver
update made me check there weren't any others hiding, and I found this
one.

Pull ARM SoC late updates from Olof Johansson:
"This is some material that we picked up into our tree late, or that
had more complex dependencies on more than one topic branch that makes
sense to keep separately.
- TI support for secure accelerators and hwrng on OMAP4/5
- TI camera changes for dra7 and am437x and SGX improvement due to
better reset control support on am335x, am437x and dra7
- Davinci moves to proper clocksource on DM365, and regulator/audio
improvements for DM365 and DM644x eval boards"
