This patch adds few AHUB modules for Tegra210, Tegra186 and Tegra194.
Bindings for following modules are added.
* AHUB added as a child node under ACONNECT
* AHUB includes many HW accelerators and below components are added
as its children.
* ADMAIF
* I2S
* DMIC
* DSPK (added for Tegra186 and Tegra194 only, since Tegra210 does
not have this module)

When kernel module loading failed, user space only get one of the
following error messages:
- ENOEXEC
This is the most confusing one. From corrupted ELF header to bad
WRITE|EXEC flags check introduced by in module_enforce_rwx_sections()
all returns this error number.
- EPERM
This is for blacklisted modules. But mod doesn't do extra explain
on this error either.
- ENOMEM
The only error which needs no explain.
This means, if a user got "Exec format error" from modprobe, it provides
no meaningful way for the user to debug, and will take extra time
communicating to get extra info.
So this patch will add extra error messages for -ENOEXEC and -EPERM
errors, allowing user to do better debugging and reporting.

ovl_can_list() should return false for overlay private xattrs. Since
currently these use the "trusted.overlay." prefix, they will always match
the "trusted." prefix as well, hence the test for being non-trusted will
not trigger.

private xattr before the test for non-trusted.

Container folks are complaining that dnf/yum issues too many sync while
installing packages and this slows down the image build. Build requirement
is such that they don't care if a node goes down while build was still
going on. In that case, they will simply throw away unfinished layer and
start new build. So they don't care about syncing intermediate state to the
disk and hence don't want to pay the price associated with sync.
So they are asking for mount options where they can disable sync on overlay
mount point.
They primarily seem to have two use cases.
- For building images, they will mount overlay with nosync and then sync
upper layer after unmounting overlay and reuse upper as lower for next
layer.
- For running containers, they don't seem to care about syncing upper layer
because if node goes down, they will simply throw away upper layer and
create a fresh one.
So this patch provides a mount option "volatile" which disables all forms
of sync. Now it is caller's responsibility to throw away upper if system
crashes or shuts down and start fresh.
With "volatile", I am seeing roughly 20% speed up in my VM where I am just
installing emacs in an image. Installation time drops from 31 seconds to 25
seconds when nosync option is used. This is for the case of building on top
of an image where all packages are already cached. That way I take out the
network operations latency out of the measurement.
Giuseppe is also looking to cut down on number of iops done on the disk. He
is complaining that often in cloud their VMs are throttled if they cross
the limit. This option can help them where they reduce number of iops (by
cutting down on frequent sync and writebacks).

An incompatible feature is marked by a non-empty directory nested
2 levels deep under "work" dir, e.g.:
workdir/work/incompat/volatile.
This commit checks for marked incompat features, warns about them
and fails to mount the overlay, for example:
overlayfs: overlay with incompat feature 'volatile' cannot be mounted
Very old kernels (i.e. v3.18) will fail to remove a non-empty "work"
dir and fail the mount. Newer kernels will fail to remove a "work"
dir with entries nested 3 levels and fall back to read-only mount.
User mounting with old kernel will see a warning like these in dmesg:
overlayfs: cleanup of 'incompat/...' failed (-39)
overlayfs: cleanup of 'work/incompat' failed (-39)
overlayfs: cleanup of 'ovl-work/work' failed (-39)
overlayfs: failed to create directory /vdf/ovl-work/work (errno: 17);
mounting read-only
These warnings should give the hint to the user that:
1. mount failure is caused by backward incompatible features
2. mount failure can be resolved by manually removing the "work" directory
There is nothing preventing users on old kernels from manually removing
workdir entirely or mounting overlay with a new workdir, so this is in
no way a full proof backward compatibility enforcement, but only a best
effort.

This patch fixes a few bugs:
1- We weren't taking into account sha_leftovers when adding multiple
ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
the beginning of ksv[j]
2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was
being placed on the wrong half of sha_text, overlapping the leftover
ksv value
3- In the sha_leftovers == 2 case, we need to manually terminate the
byte stream with 0x80 since the hardware doesn't have enough room to
add it after writing M0
The upside is that all of the HDCP supported HDMI repeaters I could
find on Amazon just strip HDCP anyways, so it turns out to be _really_
hard to hit any of these cases without an MST hub, which is not (yet)
supported. Oh, and the sha_leftovers == 1 case works perfectly!

In practice, the bug this warning appears to be concerned with would not
actually matter because ret gets initialized to the return value of
cnl_verify_procmon_ref_values. However, that does appear to be a bug
since it means the first hunk of the patch this fixes won't actually do
anything (since the values of check_phy_reg won't factor into the final
ret value). Initialize ret to true then make all of the assignments a
bitwise AND with itself so that the function always does what it should

In the arm64 module linker script, the section .text.ftrace_trampoline
is specified unconditionally regardless of whether CONFIG_DYNAMIC_FTRACE
is enabled (this is simply due to the limitation that module linker
scripts are not preprocessed like the vmlinux one).
Normally, for .plt and .text.ftrace_trampoline, the section flags
present in the module binary wouldn't matter since module_frob_arch_sections()
would assign them manually anyway. However, the arm64 module loader only
sets the section flags for .text.ftrace_trampoline when CONFIG_DYNAMIC_FTRACE=y.
That's only become problematic recently due to a recent change in
binutils-2.35, where the .text.ftrace_trampoline section (along with the
.plt section) is now marked writable and executable (WAX).
We no longer allow writable and executable sections to be loaded due to
commit 5c3a7db0c7 ("module: Harden STRICT_MODULE_RWX"), so this is
causing all modules linked with binutils-2.35 to be rejected under arm64.
Drop the IS_ENABLED(CONFIG_DYNAMIC_FTRACE) check in module_frob_arch_sections()
so that the section flags for .text.ftrace_trampoline get properly set to
SHF_EXECINSTR|SHF_ALLOC, without SHF_WRITE.

Create a generic ECC engine framework. This is a base to instantiate ECC
engine objects.
If we really want to be generic, bindings must evolve, so here is the
new logic. The following three properties are mutually exclusive:
- The nand-no-ecc-engine boolean property is set and there is no
ECC engine to retrieve.
- The nand-use-soft-ecc-engine boolean property is set and the core
will force using the use of software correction.
- There is a nand-ecc-engine property pointing at a node which will
act as ECC engine.
It the later case, the property may reference:
- The NAND chip node itself (for the on-die ECC case).
- The parent node if the NAND controller embeds an ECC engine.
- Any other node being an external ECC controller as well.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Merge tag 'perf-tools-fixes-for-v5.9-2020-09-01' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fix infinite loop in the TUI for grouped events in 'perf top/record',
eg when using "perf top -e '{cycles,instructions,cache-misses}'".
- Fix segfault by skipping side-band event setup if HAVE_LIBBPF_SUPPORT
is not set.
- Fix synthesized branch stacks generated from CoreSight ETM trace and
Intel PT hardware traces.
- Fix error when synthesizing events from ARM SPE hardware trace.
- The SNOOPX and REMOTE offsets in the data_src bitmask in perf records
were were both 37, SNOOPX is 38, fix it.
- Fix use of CPU list with summary option in 'perf sched timehist'.
- Avoid an uninitialized read when using fake PMUs.
- Set perf_event_attr.exclude_guest=1 for user-space counting.
- Don't order events when doing a 'perf report -D' raw dump of
perf.data records.
- Set NULL sentinel in pmu_events table in "Parse and process metrics"
'perf test'
- Fix basic bpf filtering 'perf test' on s390x.
- Fix out of bounds array access in the 'perf stat' print_counters()

kfree_skb() handles a NULL skb argument so the additional check is
unnecessary. Remove it.

Fix ufshcd_print_trs() to consider UFSHCD_QUIRK_PRDT_BYTE_GRAN when using
utp_transfer_req_desc::prd_table_length, so that it doesn't treat the
number of bytes as the number of entries.

It was discovered that sdparm will fail when attempting to disable write
cache on a SATA disk connected via libsas.
In the ATA command set the write cache state is controlled through the SET
FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and
the latter command is what is used in the SCSI-ATA translation layer. A
subtle difference is that a MODE SELECT carries data whereas SET FEATURES
is defined as a non-data command in ATA.
Set the DMA data direction to DMA_NONE if the requested ATA command is
identified as non-data.

If WRITE_ZERO/WRITE_SAME operation is not supported by the storage,
blk_cloned_rq_check_limits() will return IO error which will cause
device-mapper to fail the paths.
Instead, if the queue limit is set to 0, return BLK_STS_NOTSUPP.
BLK_STS_NOTSUPP will be ignored by device-mapper and will not fail the
paths.
