This is a pure band-aid so that I can continue merging stuff from people
while some of the gcc-12 fallout gets sorted out.

In particular, gcc-12 is very unhappy about the kinds of pointer
arithmetic tricks that netfs does, and that makes the fortify checks
trigger in afs and ceph:

  In function ‘fortify_memset_chk’,
      inlined from ‘netfs_i_context_init’ at include/linux/netfs.h:327:2,
      inlined from ‘afs_set_netfs_context’ at fs/afs/inode.c:61:2,
      inlined from ‘afs_root_iget’ at fs/afs/inode.c:543:2:
  include/linux/fortify-string.h:258:25: warning: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
    258 |                         __write_overflow_field(p_size_field, size);
        |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and the reason is that netfs_i_context_init() is passed a 'struct inode'
pointer, and then it does

        struct netfs_i_context *ctx = netfs_i_context(inode);

        memset(ctx, 0, sizeof(*ctx));

where that netfs_i_context() function just does pointer arithmetic on
the inode pointer, knowing that the netfs_i_context is laid out
immediately after it in memory.

This is all truly disgusting, since the whole "netfs_i_context is laid
out immediately after it in memory" is not actually remotely true in
general, but is just made to be that way for afs and ceph.

See for example fs/cifs/cifsglob.h:

  struct cifsInodeInfo {
        struct {
                /* These must be contiguous */
                struct inode    vfs_inode;      /* the VFS's inode record */
                struct netfs_i_context netfs_ctx; /* Netfslib context */
        };
	[...]

and realize that this is all entirely wrong, and the pointer arithmetic
that netfs_i_context() is doing is also very very wrong and wouldn't
give the right answer if netfs_ctx had different alignment rules from a
'struct inode', for example).

Anyway, that's just a long-winded way to say "the gcc-12 warning is
actually quite reasonable, and our code happens to work but is pretty
disgusting".

This is getting fixed properly, but for now I made the mistake of
thinking "the week right after the merge window tends to be calm for me
as people take a breather" and I did a sustem upgrade.  And I got gcc-12
as a result, so to continue merging fixes from people and not have the
end result drown in warnings, I am fixing all these gcc-12 issues I hit.

Including with these kinds of temporary fixes.

In commit 8b202ee2 ("s390: disable -Warray-bounds") the s390 people
disabled the '-Warray-bounds' warning for gcc-12, because the new logic
in gcc would cause warnings for their use of the S390_lowcore macro,
which accesses absolute pointers.

It turns out gcc-12 has many other issues in this area, so this takes
that s390 warning disable logic, and turns it into a kernel build config
entry instead.

Part of the intent is that we can make this all much more targeted, and
use this conflig flag to disable it in only particular configurations
that cause problems, with the s390 case as an example:

        select GCC12_NO_ARRAY_BOUNDS

and we could do that for other configuration cases that cause issues.

Or we could possibly use the CONFIG_CC_NO_ARRAY_BOUNDS thing in a more
targeted way, and disable the warning only for particular uses: again
the s390 case as an example:

  KBUILD_CFLAGS_DECOMPRESSOR += $(if $(CONFIG_CC_NO_ARRAY_BOUNDS),-Wno-array-bounds)

but this ends up just doing it globally in the top-level Makefile, since
the current issues are spread fairly widely all over:

  KBUILD_CFLAGS-$(CONFIG_CC_NO_ARRAY_BOUNDS) += -Wno-array-bounds

We'll try to limit this later, since the gcc-12 problems are rare enough
that *much* of the kernel can be built with it without disabling this
warning.

gcc-12 started warning about 'tracker' being used uninitialized:

  drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:786:28: warning: ‘tracker’ is used uninitialized [-Wuninitialized]

which seems to be because it doesn't track how the use (and
initialization) is bound by the 'do_bond' flag.

But admittedly that 'do_bond' usage is fairly complicated, and involves
passing it around as an argument to helper functions, so it's somewhat
understandable that gcc doesn't see how that all works.

This function could be rewritten to make the use of that tracker
variable more obviously safe, but for now I'm just adding the forced
initialization of it.

While the concept of checking for dangling pointers to local variables
at function exit is really interesting, the gcc-12 implementation is not
compatible with reality, and results in false positives.

For example, gcc sees us putting things on a local list head allocated
on the stack, which involves exactly those kinds of pointers to the
local stack entry:

  In function ‘__list_add’,
      inlined from ‘list_add_tail’ at include/linux/list.h:102:2,
      inlined from ‘rebuild_snap_realms’ at fs/ceph/snap.c:434:2:
  include/linux/list.h:74:19: warning: storing the address of local variable ‘realm_queue’ in ‘*&realm_27(D)->rebuild_item.prev’ [-Wdangling-pointer=]
     74 |         new->prev = prev;
        |         ~~~~~~~~~~^~~~~~

But then gcc - understandably - doesn't really understand the big
picture how the doubly linked list works, so doesn't see how we then end
up emptying said list head in a loop and the pointer we added has been
removed.

Gcc also complains about us (intentionally) using this as a way to store
a kind of fake stack trace, eg

  drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]
     40 |         acpi_gbl_entry_stack_pointer = &current_sp;
        |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~

which is entirely reasonable from a compiler standpoint, and we may want
to change those kinds of patterns, but not not.

So this is one of those "it would be lovely if the compiler were to
complain about us leaving dangling pointers to the stack", but not this
way.

Gcc-12 correctly warned about this code using a non-NULL pointer as a

        |                     ^

due to the extraneous '&' address-of operator.

Philipp Zabel points out that The mistake had no adverse effect since
the following condition doesn't actually dereference the NULL pointer,
but the intent of the code was obviously to check for it, not to take
the address of the member.

vmxnet3: upgrade to version 7

vmxnet3 emulation has recently added several new features including
support for uniform passthrough(UPT). To make UPT work vmxnet3 has
to be enhanced as per the new specification. This patch series
extends the vmxnet3 driver to leverage these new features.

Compatibility is maintained using existing vmxnet3 versioning mechanism as
follows:
 - new features added to vmxnet3 emulation are associated with new vmxnet3
   version viz. vmxnet3 version 7.
 - emulation advertises all the versions it supports to the driver.
 - during initialization, vmxnet3 driver picks the highest version number
 supported by both the emulation and the driver and configures emulation
 to run at that version.

In particular, following changes are introduced:

Patch 1:
  This patch introduces utility macros for vmxnet3 version 7 comparison
  and updates Copyright information.

Patch 2:
  This patch adds new capability registers to fine control enablement of
  individual features based on emulation and passthrough.

Patch 3:
  This patch adds support for large passthrough BAR register.

Patch 4:
  This patch adds support for out of order rx completion processing.

Patch 5:
  This patch introduces new command to set ring buffer sizes to pass this
  information to the hardware.

Patch 6:
  For better performance, hardware has a requirement to limit number of TSO
  descriptors. This patch adds that support.

Patch 7:
  With vmxnet3 version 7, new descriptor fields are used to indicate
  encapsulation offload.

Patch 8:
  With all vmxnet3 version 7 changes incorporated in the vmxnet3 driver,
  with this patch, the driver can configure emulation to run at vmxnet3
  version 7.

Changes in v2->v3:
 - use correct byte ordering for ringBufSize

Changes in v2:
 - use local rss_fields variable for the rss capability checks in patch 2

VMXNET3_CAP_LARGE_BAR needs to be set by the device. If it is not set

This patch enhances vmxnet3 to suuport capability registers which
allows it to enable features selectively. The DCR register tracks
the capabilities vmxnet3 device supports. The PTCR register states
the capabilities that the passthrough device supports.

With the help of these registers, vmxnet3 can enable only those
features which the passthrough device supoprts. This allows
smooth trasition to Uniform-Passthrough (UPT) mode if the virtual
nic requests it. If PTCR register returns nothing or error it means
UPT is not being requested and vnic will continue in emulation mode.

Variadic functions (printf-like) undergo default argument promotion.
Documentation/core-api/printk-formats.rst specifically recommends
using the promoted-to-type's format flag.

Also, as per C11 6.3.1.1:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf)
`If an int can represent all values of the original type ..., the
value is converted to an int; otherwise, it is converted to an
unsigned int. These are called the integer promotions.`

Since the argument is a u16 it will get promoted to an int and thus it is
most accurate to use the %x format specifier here. It should be noted that the
`#06` formatting sugar does not alter the promotion rules.

Since commit a18e6521 ("net: phylink: handle NA interface mode in
phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode
or phy-connection-type property is specified in a DSA port node of the
device tree. The same commit caused a regression in rtl8365mb whereby
phylink would fail to connect, because the driver did not advertise
support for GMII for ports with internal PHY.

It should be noted that the aforementioned regression is not because the
blamed commit was incorrect: on the contrary, the blamed commit is
correcting the previous behaviour whereby unspecified phy-mode would
cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The
rtl8365mb driver only worked by accident before because it _did_
advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved
for internal use by phylink. With one mistake fixed, the other was
exposed.

Commit a5dba0f2 ("net: dsa: rtl8365mb: add GMII as user port mode")
then introduced implicit support for GMII mode on ports with internal
PHY to allow a PHY connection for device trees where the phy-mode is not
explicitly set to "internal". At this point everything was working OK
again.

Subsequently, commit 6ff60646 ("net: dsa: realtek: convert to
phylink_generic_validate()") broke this behaviour again by discarding
the usage of rtl8365mb_phy_mode_supported() - where this GMII support
was indicated - while switching to the new .phylink_get_caps API.

With the new API, rtl8365mb_phy_mode_supported() is no longer needed.
Remove it altogether and add back the GMII capability - this time to
rtl8365mb_phylink_get_caps() - so that the above default behaviour works
for ports with internal PHY again.

40GbE Intel Wired LAN Driver Updates 2022-06-07

This series contains updates to i40e and iavf drivers.

Mateusz adds implementation for setting VF VLAN pruning to allow user to
specify visibility of VLAN tagged traffic to VFs for i40e. He also adds
waiting for result from PF for setting MAC address in iavf.

mv88e6xxx: fixes for reading serdes state

These are some low-priority fixes to the mv88e6xxx serdes code.
Patch 1 fixes the reporting of an_complete, which is used in the
emulation of a conventional C22 PHY. Patch from Marek.

Patch 2 makes one of the error messages in patch 2 to be consistent
with the other error messages in this function.

Patch 3 ensures that we do not miss a link-failure event.

Phylink wants to know if the link has dropped since the last time state
was retrieved, and the BMSR gives us that. Read the BMSR and use it when
deciding the link state. Fill in the an_complete member as well for the
emulated PHY state.

Other errors accessing the registers in mv88e6352_serdes_pcs_get_state()
print "PHY " before the register name, except for the BMSR. Make this
consistent with the other error messages.

Commit ede359d8 ("net: dsa: mv88e6xxx: Link in pcs_get_state() if AN
is bypassed") added the ability to link if AN was bypassed, and added
filling of state->an_complete field, but set it to true if AN was
enabled in BMCR, not when AN was reported complete in BMSR.

This was done because for some reason, when I wanted to use BMSR value
to infer an_complete, I was looking at BMSR_ANEGCAPABLE bit (which was
always 1), instead of BMSR_ANEGCOMPLETE bit.

Use BMSR_ANEGCOMPLETE for filling state->an_complete.
