Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
- Fix probing of precise_ip level for default cycles event, that
got broken recently on x86_64 when its arch code started
considering invalid requesting precise samples when not sampling
(i.e. when attr.sample_period == 0).
This also fixes another problem in s/390 where the precision
probing with sample_period == 0 returned precise_ip > 0, that
then, when setting up the real cycles event (not probing) would
return EOPNOTSUPP for precise_ip > 0 (as determined previously
by probing) and sample_period > 0.
These problems resulted in attr_precise not being set to the
highest precision available on x86.64 when no event was specified,
i.e. the canonical:
perf record ./workload
would end up using attr.precise_ip = 0. As a workaround this would
need to be done:
perf record -e cycles:P ./workload
And on s/390 it would plain not work, requiring using:
perf record -e cycles ./workload
as a workaround. (Arnaldo Carvalho de Melo)
- Fix perf build with ARCH=x86_64, when ARCH should be transformed
into ARCH=x86, just like with the main kernel Makefile and
tools/objtool's, i.e. use SRCARCH. (Jiada Wang)
- Avoid accessing uninitialized data structures when unwinding with
elfutils's libdw, making it more closely mimic libunwind's unwinder.

Similarly to how cross-chip VLAN works, define a bitmap of multicast
group members for a switch, now including its DSA ports, so that
multicast traffic can be sent to all switches of the fabric.
A switch may drop the frames if no user port is a member.
This brings support for multicast in a multi-chip environment.
As of now, all switches of the fabric must support the multicast
operations in order to program a single fabric port.

When booting into the kdump/kexec kernel, pHyp and vios
are not prepared for the initialization crq request and
a failover transport event is generated. This is not
handled correctly.
At this point in initialization the driver is still in
the 'probing' state and cannot handle a full reset of the
driver as is normally done for a failover transport event.
To correct this we catch driver resets while still in the
'probing' state and return EAGAIN. This results in the
driver tearing down the main crq and calling ibmvnic_init()
again.

All supported Meson SoCs have a random number generator in CBUS.
Newer SoCs (GXBB, GXL and GXM) provide only one 32-bit random number
register, whereas the older SoCs (Meson6, Meson8 and Meson8b) have two
32-bit random number registers. The existing meson-rng driver only
supports the lower 32-bit - but it still works fine on the older SoCs

There seem to be two memory regions that need to be reserved, otherwise
the system just hangs when running:
$ stress --vm-bytes $(awk '/MemFree/{printf "%d\n", $2 * 0.9;}' < /proc/meminfo)k \
--vm-keep -m 1
The first memory region is really crucial and without it the system
hangs. I could not find any references to this in Amlogic's GPL kernel
sources.
The second region is used by the "suspend firmware". The u-boot sources
(/arch/arm/cpu/aml_meson/m8/firmwareld.c) state that the suspend
firmware is located at "64M + 15M" which matches CONFIG_MESON_SUSPEND in
the Amlogic GPL kernel sources. The "suspend firmware" is responsible
for waking up the system from suspend state.
This also fixes reading the full SD card as without this the system
would simply hang (probably related to the first memory region, if some
buffer is allocated there).

In the existing dn_route.c code, dn_route_output_slow() takes
dst->__refcnt before calling dn_insert_route() while dn_route_input_slow()
does not take dst->__refcnt before calling dn_insert_route().
This makes the whole routing code very buggy.
In dn_dst_check_expire(), dnrt_free() is called when rt expires. This
makes the routes inserted by dn_route_output_slow() not able to be
freed as the refcnt is not released.
In dn_dst_gc(), dnrt_drop() is called to release rt which could
potentially cause the dst->__refcnt to be dropped to -1.
In dn_run_flush(), dst_free() is called to release all the dst. Again,
it makes the dst inserted by dn_route_output_slow() not able to be
released and also, it does not wait on the rcu and could potentially
cause crash in the path where other users still refer to this dst.
This patch makes sure both input and output path do not take
dst->__refcnt before calling dn_insert_route() and also makes sure
dnrt_free()/dst_free() is called when removing dst from the hash table.

Each time we get an incoming SYN to the RDS_TCP_PORT, the TCP
layer accepts the connection and then the rds_tcp_accept_one()
callback is invoked to process the incoming connection.
rds_tcp_accept_one() may reject the incoming syn for a number of
reasons, e.g., commit 1a0e100fb2 ("RDS: TCP: Force every connection
to be initiated by numerically smaller IP address"), or because
we are getting spammed by a malicious node that is triggering
a flood of connection attempts to RDS_TCP_PORT. If the incoming
syn is rejected, no data would have been sent on the TCP socket,
and we do not need to be in TIME_WAIT state, so we set linger on
the TCP socket before closing, thereby closing the socket efficiently
with a RST.
