5190044c29 modpost: move the namespace field in Module.symvers last
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 bd5cbcedf44), 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.

f2c2e71764 usb: gadget: add raw-gadget interface
USB Raw Gadget is a kernel module that provides a userspace interface for
the USB Gadget subsystem. Essentially it allows to emulate USB devices
from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
currently a strictly debugging feature and shouldn't be used in
production.

Raw Gadget is similar to GadgetFS, but provides a more low-level and
direct access to the USB Gadget layer for the userspace. The key
differences are:

1. Every USB request is passed to the userspace to get a response, while
   GadgetFS responds to some USB requests internally based on the provided
   descriptors. However note, that the UDC driver might respond to some
   requests on its own and never forward them to the Gadget layer.

2. GadgetFS performs some sanity checks on the provided USB descriptors,
   while Raw Gadget allows you to provide arbitrary data as responses to
   USB requests.

3. Raw Gadget provides a way to select a UDC device/driver to bind to,
   while GadgetFS currently binds to the first available UDC.

4. Raw Gadget uses predictable endpoint names (handles) across different
   UDCs (as long as UDCs have enough endpoints of each required transfer
   type).

5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.

when reading the GICv4.1 GICD_TYPER2 register, which is unexpected...

Work around it by adding a new quirk for the following variants:

 ThunderX: CN88xx
 OCTEON TX: CN83xx, CN81xx
 OCTEON TX2: CN93xx, CN96xx, CN98xx, CNF95xx*

and use this flag to avoid accessing GICD_TYPER2. Note that all
reserved registers (including redistributors and ITS) are impacted
by this erratum, but that only GICD_TYPER2 has to be worked around
so far.

d9a9f4849f cifs_atomic_open(): fix double-put on late allocation failure
several iterations of ->atomic_open() calling conventions ago, we
used to need fput() if ->atomic_open() failed at some point after
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
fixed...

62790268e4 ARM: SoC fixes
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.
 
  ... and the usual collection of smaller fixes to various platforms.

b34e5c1332 Driver core / debugfs fixes for 5.6-rc5
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.

26d5bb9e4c dt-bindings: net: FMan erratum A050385
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.

d2334a91a3 dt-bindings: arm: Fixup the DT bindings for hierarchical PSCI states
The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the
power-domain DT binding.

Additionally, update the example to conform to the new pattern, but also to
the adjusted domain-idle-state DT binding.
