DTS changes for omaps for v5.8 merge window
We add support for beaglebone-ai board that's am5729 based devices.
Then we have a series changes to configure more hardware acceletators found
on omap variants. With the recent ti-sysc related changes, we can now better
configure the accelerators with help of the clock framework and reset driver.
So with a series of changes from Suman Anna and Tero Kristo, let's configure
IPUs and DSPs for dra7 devices like beagle-x15. And let's also configure the
missing crypto accelerators for omap5 as those have been missing.
Note that there are still some pending driver related patches to use IPU and
DSP related features with mainline kernel, but those are independent of the
devicetree changes.
Then there is a display related change for am57xx-idk for tc358778 bridge,
and a change to configure the missing clock source for some PWM timers.

ARM: dts: dra7-ipu-dsp-common: Add watchdog timers to IPU and DSP nodes
The watchdog timer information has been added to all the IPU and DSP
remote processor device nodes in the DRA7xx/AM57xx SoC families. The
data has been added to the two common dra7-ipu-dsp-common and
dra74-ipu-dsp-common dtsi files that can be included by all the
desired board files. The following timers are chosen as the watchdog
timers, as per the usage on the current firmware images:
IPU2: GPTimers 4 & 9 (one for each Cortex-M4 core)
IPU1: GPTimers 7 & 8 (one for each Cortex-M4 core)
DSP1: GPTimer 10
DSP2: GPTimer 13
Each of the IPUs has two Cortex-M4 processors and so uses a timer
each for providing watchdog support on that processor irrespective of
whether the IPU is running in SMP-mode or non-SMP node. The chosen
timers also need to be unique from the ones used by other processors
(regular timers or watchdog timers) so that they can be supported
simultaneously.
The MPU-side drivers will use this data to initialize the watchdog
timer(s), and listen for any watchdog triggers. The BIOS-side code on
these processors needs to configure/refresh the corresponding timer
properly to not throw a watchdog error.
The watchdog timers are optional in general, but are mandatory to
be added to support watchdog error recovery on a particular processor.
These timers can be changed or removed as per the system integration
needs, alongside appropriate equivalent changes on the firmware side.

ARM: dts: DRA74x: Add DSP2 processor device node
The DRA7xx family of SoCs can contain upto two identical DSP
processor subsystems. The second DSP processor subsystem is
present only on the DRA74x/DRA76x variants. The processor
device DT node has therefore been added in disabled state for
this processor subsystem in the DRA74x specific DTS file.
NOTE:
1. The node does not have any mailboxes, timers or CMA region
assigned, they should be added in the respective board dts
files.
2. The node should also be enabled as per the individual product
configuration in the corresponding board dts files.

ARM: dts: DRA7: Add common IPU and DSP nodes
The DRA7xx family of SOCs have two IPUs and upto two DSP
processor subsystems in general. The IPU processor subsystem
contains dual-core ARM Cortex-M4 processors, while the DSP
processor subsystem is based on the TI's standard TMS320C66x
DSP CorePac core. The IPUs are very similar to those on OMAP5.
Two IPUs and one DSP processor subsystems is the most common
configuration. The processor device DT nodes have been added
for these processor subsystems, with the internal memories
added through 'reg' and 'reg-names' properties. The IPUs only
have an L2 RAM, whereas the DSPs have L1P, L1D and L2 RAM
memories.
NOTE:
1. The nodes do not have any mailboxes, timers or CMA regions
assigned, they should be added in the respective board dts
files.
2. The nodes haven been disabled by default and the enabling
of these nodes is also left to the respective board dts

iommu: Properly export iommu_group_get_for_dev()
In commit
a7ba5c3d008d ("drivers/iommu: Export core IOMMU API symbols to
permit modular drivers") a bunch of iommu symbols were exported, all
with _GPL markings except iommu_group_get_for_dev(). That export should
also be _GPL like the others.

iommu/amd: Fix legacy interrupt remapping for x2APIC-enabled system
Currently, system fails to boot because the legacy interrupt remapping
mode does not enable 128-bit IRTE (GA), which is required for x2APIC
support.
Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with
kernel option amd_iommu_intr=legacy instead. The initialization
logic will check GASup and automatically fallback to using
AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.

arm64: vdso: Add -fasynchronous-unwind-tables to cflags
On arm64 linux gcc uses -fasynchronous-unwind-tables -funwind-tables
by default since gcc-8, so now the de facto platform ABI is to allow
unwinding from async signal handlers.
However on bare metal targets (aarch64-none-elf), and on old gcc,
async and sync unwind tables are not enabled by default to avoid
runtime memory costs.
This means if linux is built with a baremetal toolchain the vdso.so
may not have unwind tables which breaks the gcc platform ABI guarantee
in userspace.
Add -fasynchronous-unwind-tables explicitly to the vgettimeofday.o
cflags to address the ABI change.

bd_super sets it has a mount file system on it (although not every
mounted file system sets bd_super), but that also implies it doesn't even

fibmap: Warn and return an error in case of block > INT_MAX
We better warn the fibmap user and not return a truncated and therefore
an incorrect block map address if the bmap() returned block address
is greater than INT_MAX (since user supplied integer pointer).
It's better to pr_warn() all user of ioctl_fibmap() and return a proper
error code rather than silently letting a FS corruption happen if the
user tries to fiddle around with the returned block map address.
We fix this by returning an error code of -ERANGE and returning 0 as the
block mapping address in case if it is > INT_MAX.
Now iomap_bmap() could be called from either of these two paths.
Either when a user is calling an ioctl_fibmap() interface to get
the block mapping address or by some filesystem via use of bmap()
internal kernel API.
bmap() kernel API is well equipped with handling of u64 addresses.
WARN condition in iomap_bmap_actor() was mainly added to warn all
the fibmap users. But now that we have directly added this warning
for all fibmap users and also made sure to return 0 as block map address
in case if addr > INT_MAX.
So we can now remove this logic from iomap_bmap_actor().

dm multipath: use updated MPATHF_QUEUE_IO on mapping for bio-based mpath
When adding devices that don't have a scsi_dh on a BIO based multipath,
I was able to consistently hit the warning below and lock-up the system.
The problem is that __map_bio reads the flag before it potentially being
modified by choose_pgpath, and ends up using the older value.
The WARN_ON below is not trivially linked to the issue. It goes like
this: The activate_path delayed_work is not initialized for non-scsi_dh
devices, but we always set MPATHF_QUEUE_IO, asking for initialization.
That is fine, since MPATHF_QUEUE_IO would be cleared in choose_pgpath.
Nevertheless, only for BIO-based mpath, we cache the flag before calling
choose_pgpath, and use the older version when deciding if we should
initialize the path. Therefore, we end up trying to initialize the
paths, and calling the non-initialized activate_path work.

Fix use after free in get_tree_bdev()
Commit
6fcf0c72e4b9, a fix to get_tree_bdev() put a missing blkdev_put() in
the wrong place, before a warnf() that displays the bdev under
consideration rather after it.
This results in a silent lockup in printk("%pg") called via warnf() from
get_tree_bdev() under some circumstances when there's a race with the
blockdev being frozen. This can be caused by xfstests/tests/generic/085 in
combination with Lukas Czerner's ext4 mount API conversion patchset. It
looks like it ought to occur with other users of get_tree_bdev() such as
XFS, but apparently doesn't.

drm/amd/display: Defer cursor update around VUPDATE for all ASIC
[Why]
Fixes the following scenario:
- Flip has been prepared sometime during the frame, update pending
- Cursor update happens right when VUPDATE would happen
- OPTC lock acquired, VUPDATE is blocked until next frame
- Flip is delayed potentially infinitely
With the igt@kms_cursor_legacy cursor-vs-flip-legacy test we can
observe nearly *13* frames of delay for some flips on Navi.
[How]
Apply the Raven workaround generically. When close enough to VUPDATE
block cursor updates from occurring from the dc_stream_set_cursor_*
helpers.
This could perhaps be a little smarter by checking if there were
pending updates or flips earlier in the frame on the HUBP side before
applying the delay, but this should be fine for now.
This fixes the kms_cursor_legacy test.
