MPTCP sk_forward_memory handling is a bit special, as such field
is protected by the msk socket spin_lock, instead of the plain
socket lock.

Currently we have a code path updating such field without handling
the relevant lock:

__mptcp_retrans() -> __mptcp_clean_una_wakeup()

Several helpers in __mptcp_clean_una_wakeup() will update
sk_forward_alloc, possibly causing such field corruption, as reported
by Matthieu.

Address the issue providing and using a new variant of blamed function
which explicitly acquires the msk spin lock.

In subflow_syn_recv_sock() we currently skip options parsing
for OoO packet, given that such packets may not carry the relevant
MPC option.

If the peer generates an MPC+data TSO packet and some of the early
segments are lost or get reorder, we server will ignore the peer key,
causing transient, unexpected fallback to TCP.

The solution is always parsing the incoming MPTCP options, and
do the fallback only for in-order packets. This actually cleans
the existing code a bit.

When some mapping related errors occurs we close the main

====================
mptcp: Fixes for 5.13

These patches address two issues in MPTCP.

Patch 1 fixes a locking issue affecting MPTCP-level retransmissions.

Patches 2-4 improve handling of out-of-order packet arrival early
in a connection, so it falls back to TCP rather than forcing a
reset. Includes a selftest.

PIC interrupts do not support affinity setting and they can end up on
any online CPU. Therefore, it's required to mark the associated vectors
as system-wide reserved. Otherwise, the corresponding irq descriptors
are copied to the secondary CPUs but the vectors are not marked as
assigned or reserved. This works correctly for the IO/APIC case.

When the IO/APIC is disabled via config, kernel command line or lack of
enumeration then all legacy interrupts are routed through the PIC, but
nothing marks them as system-wide reserved vectors.

As a consequence, a subsequent allocation on a secondary CPU can result in
allocating one of these vectors, which triggers the BUG() in
apic_update_vector() because the interrupt descriptor slot is not empty.

Imran tried to work around that by marking those interrupts as allocated
when a CPU comes online. But that's wrong in case that the IO/APIC is
available and one of the legacy interrupts, e.g. IRQ0, has been switched to
PIC mode because then marking them as allocated will fail as they are
already marked as system vectors.

Stay consistent and update the legacy vectors after attempting IO/APIC
initialization and mark them as system vectors in case that no IO/APIC is
available.

vm_create allocates memory and maps it close to GPA.  This memory
is separate from what is allocated in subsequent calls to
vm_userspace_mem_region_add, so it is incorrect to pass the
test memory size to vm_create_default.  Just pass a small
fixed amount of memory which can be used later for page table,
otherwise GPAs are already allocated at MEM_GPA and the
test aborts.

This refactors the user notification code to have a do / while loop around
the completion condition. This has a small change in semantic, in that
previously we ignored addfd calls upon wakeup if the notification had been
responded to, but instead with the new change we check for an outstanding
addfd calls prior to returning to userspace.

Rodrigo Campos also identified a bug that can result in addfd causing
an early return, when the supervisor didn't actually handle the
syscall [1].

Pull xfs fixes from Darrick Wong:
 "This week's pile mitigates some decades-old problems in how extent
  size hints interact with realtime volumes, fixes some failures in
  online shrink, and fixes a problem where directory and symlink
  shrinking on extremely fragmented filesystems could fail.

  The most user-notable change here is to point users at our (new) IRC
  channel on OFTC. Freedom isn't free, it costs folks like you and me;
  and if you don't kowtow, they'll expel everyone and take over your
  channel. (Ok, ok, that didn't fit the song lyrics...)

  Summary:

   - Fix a bug where unmapping operations end earlier than expected,
     which can cause chaos on multi-block directory and symlink shrink
     operations.

   - Fix an erroneous assert that can trigger if we try to transition a
     bmap structure from btree format to extents format with zero
     extents. This was exposed by xfs/538"

Pull RISC-V fixes from Palmer Dabbelt:
 "A handful of RISC-V related fixes:

   - avoid errors when the stack tracing code is tracing itself.

   - resurrect the memtest= kernel command line argument on RISC-V,
     which was briefly enabled during the merge window before a
     refactoring disabled it.

   - build fix and some warning cleanups"
