Given that ice_qp_dis() is called under rtnl_lock, synchronize_net() can
be called instead of synchronize_rcu() so that XDP rings can finish its

Additionally, turn off regular Tx queue before disabling irqs and NAPI.

When ice driver is spammed with multiple xdpsock instances and flow
control is enabled, there are cases when Rx queue gets stuck and unable
to reflect the disable state in QRX_CTRL register. Similar issue has
previously been addressed in commit 13a6233b03 ("ice: Add support to
enable/disable all Rx queues before waiting").
To workaround this, let us simply not wait for a disabled state as later
patch will make sure that regardless of the encountered error in the
process of disabling a queue pair, the Rx queue will be enabled.

Address a scenario in which XSK ZC Tx produces descriptors to XDP Tx
ring when link is either not yet fully initialized or process of
stopping the netdev has already started. To avoid this, add checks
against carrier readiness in ice_xsk_wakeup() and in ice_xmit_zc().
One could argue that bailing out early in ice_xsk_wakeup() would be
sufficient but given the fact that we produce Tx descriptors on behalf
of NAPI that is triggered for Rx traffic, the latter is also needed.
Bringing link up is an asynchronous event executed within
ice_service_task so even though interface has been brought up there is
still a time frame where link is not yet ok.
Without this patch, when AF_XDP ZC Tx is used simultaneously with stack
Tx, Tx timeouts occur after going through link flap (admin brings
interface down then up again). HW seem to be unable to transmit
descriptor to the wire after HW tail register bump which in turn causes
bit __QUEUE_STATE_STACK_XOFF to be set forever as
netdev_tx_completed_queue() sees no cleaned bytes on the input.

Although all current Xe2 platforms support FlatCCS, we probably
shouldn't assume that will be universally true forever. In the past
we've had platforms like PVC that didn't support compression, and the
same could show up again at some point in the future. Future-proof the
migration code by adding an explicit check for FlatCCS support to the
condition that decides whether to use a compressed PAT index for
migration.
While we're at it, we can drop the IS_DGFX check since it's redundant
with the src_is_vram check (only dGPUs have VRAM).

ARCH_DMA_MINALIGN was defined as 16 - this is too small - it may be
possible that two unrelated 16-byte allocations share a cache line. If
one of these allocations is written using DMA and the other is written
using cached write, the value that was written with DMA may be
corrupted.
This commit changes ARCH_DMA_MINALIGN to be 128 on PA20 and 32 on PA1.1 -
that's the largest possible cache line size.
As different parisc microarchitectures have different cache line size, we
define arch_slab_minalign(), cache_line_size() and
dma_get_cache_alignment() so that the kernel may tune slab cache
parameters dynamically, based on the detected cache line size.

There were spurious unaligned access warnings when calling BPF code.
Sometimes, the warnings were triggered with any incoming packet, making
the machine hard to use.
The reason for the warnings is this: on parisc64, pointers to functions
are not really pointers to functions, they are pointers to 16-byte
descriptor. The first 8 bytes of the descriptor is a pointer to the
function and the next 8 bytes of the descriptor is the content of the
"dp" register. This descriptor is generated in the function
bpf_jit_build_prologue.
The problem is that the function bpf_int_jit_compile advertises 4-byte
alignment when calling bpf_jit_binary_alloc, bpf_jit_binary_alloc
randomizes the returned array and if the array happens to be not aligned
on 8-byte boundary, the descriptor generated in bpf_jit_build_prologue is
also not aligned and this triggers the unaligned access warning.
Fix this by advertising 8-byte alignment on parisc64 when calling
bpf_jit_binary_alloc.

The broken patch results in a call to init_freq_invariance_cppc() in a CPU
hotplug handler in both the path for initially present CPUs and those
hotplugged later. That function includes a one time call to
amd_set_max_freq_ratio() which in turn calls freq_invariance_enable() that has
a static_branch_enable() which takes the cpu_hotlug_lock which is already
held.
Avoid the deadlock by using static_branch_enable_cpuslocked() as the lock will
always be already held. The equivalent path on Intel does not already hold
this lock, so take it around the call to freq_invariance_enable(), which
results in it being held over the call to register_syscall_ops, which looks to
be safe to do.

This patch addresses a regression in the ASoC STI drivers that was

that unintentionally omitted necessary probe functions for the player
and reader components.
Probe function in `sound/soc/sti/sti_uniperif.c:415` is being replaced
by another probe function located at `sound/soc/sti/sti_uniperif.c:453`,
which should instead be derived from the player and reader components.

mptcp: fix signal endpoint readd
Issue #501 [1] showed that the Netlink PM currently doesn't correctly
support removal and re-add of signal endpoints.
Patches 1 and 2 address the issue: the first one in the userspace path-
manager, introduced in v5.19 ; and the second one in the in-kernel path-
manager, introduced in v5.7.
Patch 3 introduces a related selftest. There is no 'Fixes' tag, because
it might be hard to backport it automatically, as missing helpers in
Bash will not be caught when compiling the kernel or the selftests.
The last two patches address two small issues in the MPTCP selftests,
one introduced in v6.6., and the other one in v5.17.

Currently the per connection announced address counter is never
decreased. As a consequence, after connection establishment, if
the NL PM deletes an endpoint and adds a new/different one, no
additional subflow is created for the new endpoint even if the
current limits allow that.
Address the issue properly updating the signaled address counter
every time the NL PM removes such addresses.

Currently the per-connection announced address counter is never
decreased. When the user-space PM is in use, this just affect
the information exposed via diag/sockopt, but it could still foul
the PM to wrong decision.
Add the missing accounting for the user-space PM's sake.
