MHI (Modem Host Interface) is a communication protocol used by the
host processors to control and communicate with modems over a high
speed peripheral bus or shared memory. The MHI protocol has been
designed and developed by Qualcomm Innovation Center, Inc., for use
in their modems. This commit adds the documentation for the bus and
the implementation in Linux kernel.

In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).
In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbcedf4), which is over a decade ago now.
Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.

several iterations of ->atomic_open() calling conventions ago, we

successful finish_open(). Now (since 2016) it's not needed -
struct file carries enough state to make fput() work regardless
of the point in struct file lifecycle and discarding it on
failure exits in open() got unified. Unfortunately, I'd missed
the fact that we had an instance of ->atomic_open() (cifs one)
that used to need that fput(), as well as the stale comment in
finish_open() demanding such late failure handling. Trivially

We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was
a miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing for
a while, so a few updates of that.

Here are 4 small driver core / debugfs patches for 5.6-rc3
They are:
- debugfs api cleanup now that all callers for
debugfs_create_regset32() have been fixed up. This was
waiting until after the -rc1 merge as these fixes came in
through different trees
- driver core sync state fixes based on reports of minor issues
found in the feature
All of these have been in linux-next with no reported issues.

FMAN DMA read or writes under heavy traffic load may cause FMAN
internal resource leak; thus stopping further packet processing.
The FMAN internal queue can overflow when FMAN splits single
read or write transactions into multiple smaller transactions
such that more than 17 AXI transactions are in flight from FMAN
to interconnect. When the FMAN internal queue overflows, it can
stall further packet processing. The issue can occur with any one
of the following three conditions:
1. FMAN AXI transaction crosses 4K address boundary (Errata
A010022)
2. FMAN DMA address for an AXI transaction is not 16 byte
aligned, i.e. the last 4 bits of an address are non-zero
3. Scatter Gather (SG) frames have more than one SG buffer in
the SG list and any one of the buffers, except the last
buffer in the SG list has data size that is not a multiple
of 16 bytes, i.e., other than 16, 32, 48, 64, etc.
With any one of the above three conditions present, there is
likelihood of stalled FMAN packet processing, especially under
stress with multiple ports injecting line-rate traffic.
To avoid situations that stall FMAN packet processing, all of the
above three conditions must be avoided; therefore, configure the
system with the following rules:
1. Frame buffers must not span a 4KB address boundary, unless
the frame start address is 256 byte aligned
2. All FMAN DMA start addresses (for example, BMAN buffer
address, FD[address] + FD[offset]) are 16B aligned
3. SG table and buffer addresses are 16B aligned and the size
of SG buffers are multiple of 16 bytes, except for the last
SG buffer that can be of any size.
Additional workaround notes:
- Address alignment of 64 bytes is recommended for maximally
efficient system bus transactions (although 16 byte alignment is
sufficient to avoid the stall condition)
- To support frame sizes that are larger than 4K bytes, there are
two options:
1. Large single buffer frames that span a 4KB page boundary can
be converted into SG frames to avoid transaction splits at
the 4KB boundary,
2. Align the large single buffer to 256B address boundaries,
ensure that the frame address plus offset is 256B aligned.
- If software generated SG frames have buffers that are unaligned
and with random non-multiple of 16 byte lengths, before
transmitting such frames via FMAN, frames will need to be copied
into a new single buffer or multiple buffer SG frame that is
compliant with the three rules listed above.

The devlink trigger command does not exist. While rewriting the
documentation for devlink into the reStructuredText format,
documentation for the trigger command was accidentally merged in. This
occurred because the author was also working on a potential extension to
devlink regions which included this trigger command, and accidentally
squashed the documentation incorrectly.
Further review eventually settled on using the previously unused "new"
command instead of creating a new trigger command.
Fix this by removing mention of the trigger command from the
documentation.
