Trivial fix for out-of-tree build that I wasn't testing previously:

1. Create a directory for library object files, fixes:

> make[1]: *** [Makefile:46: /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o] Error 1

2. Include $(KHDR_INCLUDES) that's exported by selftests/Makefile, fixes:
> In file included from lib/kconfig.c:6:

3. While at here, clean-up $(KSFT_KHDR_INSTALL): it's not needed anymore

Sockets in bhash are also linked to bhash2, but TIME_WAIT sockets

Let's replace tb->owners iteration in inet_csk_bind_conflict() with
two iterations over tb2->owners and tb2->deathrow.

This can be done safely under bhash's lock because socket insertion/

bhash2 added a new member sk_bind2_node in struct sock to link
sockets to bhash2 in addition to bhash.

bhash is still needed to search conflicting sockets efficiently
from a port for the wildcard address.  However, bhash itself need
not have sockets.

If we link each bhash2 bucket to the corresponding bhash bucket,
we can iterate the same set of the sockets from bhash2 via bhash.

This patch links bhash2 to bhash only, and the actual use will be

In bhash2, IPv4/IPv6 addresses are saved in two union members,
which complicate address checks in inet_bind2_bucket_addr_match()
and inet_bind2_bucket_match_addr_any() considering uninitialised
memory and v4-mapped-v6 conflicts.

Let's simplify that by saving IPv4 address as v4-mapped-v6 address
and defining tb2.rcv_saddr as tb2.v6_rcv_saddr.s6_addr32[3].

Then, we can compare v6 address as is, and after checking v4-mapped-v6,
we can compare v4 address easily.  Also, we can remove tb2->family.

intel: use bitfield operations

Jesse Brandeburg says:

After repeatedly getting review comments on new patches, and sporadic
patches to fix parts of our drivers, we should just convert the Intel code
to use FIELD_PREP() and FIELD_GET().  It's then "common" in the code and
hopefully future change-sets will see the context and do-the-right-thing.

This conversion was done with a coccinelle script which is mentioned in the
commit messages. Generally there were only a couple conversions that were
"undone" after the automatic changes because they tried to convert a
non-contiguous mask.

Patch 1 is required at the beginning of this series to fix a "forever"
issue in the e1000e driver that fails the compilation test after conversion
because the shift / mask was out of range.

The second patch just adds all the new #includes in one go.

The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the
use of the FIELD_* macros and fix up the unexpected "shifts included"
defines found while creating this series.

The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the
occasional leXX_{get,set,encode}_bits() call, as suggested by Alex.

Some drivers might misbehave if TSO packets get too big.

GVE for instance uses a 16bit field in its TX descriptor,
and will do bad things if a packet is bigger than 2^16 bytes.

Linux TCP stack honors dev->gso_max_size, but there are
other ways for too big packets to reach an ndo_start_xmit()
handler : virtio_net, af_packet, GRO...

Add a generic check in gso_features_check() and fallback
to GSO when needed.

gso_max_size was added in the blamed commit.

GCC seems to incorrectly fail to evaluate skb_ext_total_length() at
compile time under certain conditions.

The issue even occurs if all values in skb_ext_type_len[] are "0",
ruling out the possibility of an actual overflow.

As the patch has been in mainline since v6.6 without triggering the
problem it seems to be a very uncommon occurrence.

As the issue only occurs when -fno-tree-loop-im is specified as part of
CFLAGS_GCOV, disable the BUILD_BUG_ON() only when building with coverage

Only the posix timer system calls use this (when the posix timer support
is disabled, which does not actually happen in any normal case), because
they had debug code to print out a warning about missing system calls.

Get rid of that special case, and just use the standard COND_SYSCALL
interface that creates weak system call stubs that return -ENOSYS for
when the system call does not exist.

This fixes a kCFI issue with the SYS_NI() hackery:

  CFI failure at int80_emulation+0x67/0xb0 (target: sys_ni_posix_timers+0x0/0x70; expected type: 0xb02b34d9)
  WARNING: CPU: 0 PID: 48 at int80_emulation+0x67/0xb0

Pull ARM SoC fixes from Arnd Bergmann:
 "There are only a handful of bugfixes this time, which feels almost too
  small, so I hope we are not missing something important.

   - One more mediatek dts warning fix after the previous larger set,
     this should finally result in a clean defconfig build.

   - TI OMAP dts fixes for a spurious hang on am335x and invalid data on
     DTA7

   - One DTS fix for ethernet on Oriange Pi Zero (Allwinner H616)

   - A regression fix for ti-sysc interconnect target module driver to
     not access registers after reset if srst_udelay quirk is needed

Pull more bcachefs fixes from Kent Overstreet:

 - Fix a deadlock in the data move path with nocow locks (vs. update in
   place writes); when trylock failed we were incorrectly waiting for in
   flight ios to flush.

 - Fix reporting of NFS file handle length

 - Fix early error path in bch2_fs_alloc() - list head wasn't being
   initialized early enough

 - Make sure correct (hardware accelerated) crc modules get loaded

 - Fix a rare overflow in the btree split path, when the packed bkey
   format grows and all the keys have no value (LRU btree).

 - Fix error handling in the sector allocator

   This was causing writes to spuriously fail in multidevice setups, and
   another bug meant that the errors weren't being logged, only reported
   via fsync.
