Pass a dscp_t variable to xfrm_dst_lookup(), instead of an int, to
prevent accidental setting of ECN bits in ->flowi4_tos.
Only xfrm_bundle_create() actually calls xfrm_dst_lookup(). Since it
already has a dscp_t variable to pass as parameter, we only need to
remove the inet_dscp_to_dsfield() conversion.

Currently all flows for a certain SA must be processed by the same
cpu to avoid packet reordering and lock contention of the xfrm
state lock.
To get rid of this limitation, the IETF standardized per cpu SAs
in RFC 9611. This patch implements the xfrm part of it.
We add the cpu as a lookup key for xfrm states and a config option
to generate acquire messages for each cpu.
With that, we can have on each cpu a SA with identical traffic selector
so that flows can be processed in parallel on all cpus.

We introduce the same handling for potential data races with the
'fully_established' flag in subflow as previously done for
msk->fully_established.
Additionally, we make a crucial change: convert the subflow's
'fully_established' from 'bit_field' to 'bool' type. This is
necessary because methods for avoiding data races don't work well
with 'bit_field'. Specifically, the 'READ_ONCE' needs to know
the size of the variable being accessed, which is not supported in
'bit_field'. Also, 'test_bit' expect the address of 'bit_field'.

This rejects creating event if the number of arguments is over

- Repair mismatches in inode hash type, seed: different snapshot
versions of an inode must have the same hash/type seed, used for

not the type, and a user contributed a filesystem where the hash

Additionally, the hash type flip made some directory entries

====================
net: dsa: mv88e6xxx: fix MV88E6393X PHC frequency on internal clock
The MV88E6393X family of switches can additionally run their cycle
counters using a 250MHz internal clock instead of the usual 125MHz
external clock [1].
The driver currently assumes all designs utilize that external clock,
but MikroTik's RB5009 uses the internal source - causing the PHC to be
seen running at 2x real time in userspace, making synchronization
with ptp4l impossible.
This series adds support for reading off the cycle counter frequency
known to the hardware in the TAI_CLOCK_PERIOD register and picking an
appropriate set of scaling coefficients instead of using a fixed set
for each switch family.
Patch 1 groups those cycle counter coefficients into a new structure to
make it easier to pass them around.
Patch 2 modifies PTP initialization to probe TAI_CLOCK_PERIOD and
use an appropriate set of coefficients.
Patch 3 adds support for 4000ps cycle counter periods.
Changes since v2 [2]:
- Patch 1: "net: dsa: mv88e6xxx: group cycle counter coefficients"
- Moved declaration of mv88e6xxx_cc_coeffs to avoid moving that in
Patch 2.
- Patch 2: "net: dsa: mv88e6xxx: read cycle counter period from hardware"
- Removed move of mv88e6xxx_cc_coeffs declaration.
- Patch 3: "net: dsa: mv88e6xxx: support 4000ps cycle counter periods"
- No change.
