SMC-Dv2 allows users to define EIDs which allows to create separate
name spaces enabling users to cluster their SMC-Dv2 connections.
Add support for user defined EIDs and extent the generic netlink
interface so users can add, remove and dump EIDs.

mlxsw: spectrum: Adjustments to port split and label port

Jiri says:

This patchset includes patches that prepare the driver to support modular
systems.

PLLP register is introduced to get front panel port label which is no
longer equivalent to "module + 1" for modular systems, where the
numbering is per line card.

So far for all systems all front panel ports had same format and could
be split to the same number of subports. This is no longer true for
modular systems, where every line card can have different types of front
panel ports.

The PMTDB register is introduced to easily query FW for split
capabilities of particular front panel port. It is generic for use in
modular and non-modular systems.

During port creation, mlxsw_core_port_init() is called with the front
panel port number and the split port sub-number. Currently, this
information is determined by the driver without firmware assistance.

Subsequent patches are going to query this information from firmware,
but this requires the port to assigned to SWID.

Therefore, move port SWID assignment before mlxsw_core_port_init().

- Driver Registers with Devlink framework.
- Register devlink params callback for configuring device params

- Implements devlink ops flash_update callback that programs modem
  firmware.
- Creates region & snapshot required for device coredump log collection.

On early detection of device in boot rom stage. Driver registers with
Devlink framework and establish transport channel for PSI (Primary Signed
Image) injection. Once PSI is injected to device, the device execution
stage details are read to determine whether device is in flash or
exception mode. The collected information is reported to devlink user
space application & based on this informationi, application proceeds with
either modem firmware flashing or coredump collection.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, use the struct_size() helper to do the arithmetic instead of the
argument "size + count * size" in the kzalloc() function.

Pull fuse updates from Miklos Szeredi:

 - Allow mounting an active fuse device. Previously the fuse device
   would always be mounted during initialization, and sharing a fuse
   superblock was only possible through mount or namespace cloning

 - Fix data flushing in syncfs (virtiofs only)

 - Fix data flushing in copy_file_range()

 - Fix a possible deadlock in atomic O_TRUNC

 - Misc fixes and cleanups

* tag 'fuse-update-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse:
  fuse: remove unused arg in fuse_write_file_get()
  fuse: wait for writepages in syncfs
  fuse: flush extending writes
  fuse: truncate pagecache on atomic_o_trunc
  fuse: allow sharing existing sb
  fuse: move fget() to fuse_get_tree()
  fuse: move option checking into fuse_fill_super()
  fuse: name fs_context consistently
  fuse: fix use after free in fuse_read_interrupt()

Pull kgdb updates from Daniel Thompson:
 "Changes for kgdb/kdb this cycle are dominated by a change from Sumit
  that removes as small (256K) private heap from kdb. This is change
  I've hoped for ever since I discovered how few users of this heap
  remained in the kernel, so many thanks to Sumit for hunting these
  down.

  The other change is an incremental step towards SPDX headers"

* tag 'kgdb-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux:
  kernel: debug: Convert to SPDX identifier
  kdb: Rename members of struct kdbtab_t
  kdb: Simplify kdb_defcmd macro logic
  kdb: Get rid of redundant kdb_register_flags()
  kdb: Rename struct defcmd_set to struct kdb_macro
  kdb: Get rid of custom debug heap allocator

This reverts commit b6558434.

Just like with the memcg lock accounting, the kernel test robot reports
a sizeable performance regression for this commit, and while it clearly
does the rigth thing in theory, we'll need to look at just how to avoid
or minimize the performance overhead of the memcg accounting.

People already have suggestions on how to do that, but it's "future
work".

So revert it for now.

[ Note: the first link below is for this same commit but a different
  commit ID, because it's the kernel test robot ended up noticing it in
  Andrew Morton's patch queue ]
