Two BPF fixes for s390

====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The BPF feature test as well as libbpf is missing the __NR_bpf
define for s390 and currently refuses to compile (selftest suite
depends on libbpf as well). Similar issue was fixed some time
ago via b0c47807d3 ("bpf: Add sparc support to tools and
samples."), just do the same and add definitions.

While testing some other work that required JIT modifications, I
run into test_bpf causing a hang when JIT enabled on s390. The
problematic test case was the one from ddc665a4bb (bpf, arm64:
fix jit branch offset related to ldimm64), and turns out that we
do have a similar issue on s390 as well. In bpf_jit_prog() we
update next instruction address after returning from bpf_jit_insn()
with an insn_count. bpf_jit_insn() returns either -1 in case of
error (e.g. unsupported insn), 1 or 2. The latter is only the
case for ldimm64 due to spanning 2 insns, however, next address
is only set to i + 1 not taking actual insn_count into account,
thus fix is to use insn_count instead of 1. bpf_jit_enable in
mode 2 provides also disasm on s390:

mlxsw: Couple of fixes
Ido says:
The first patch prevents us from warning about valid situations that can
happen due to the fact that some operations in switchdev are deferred.
Second patch fixes a long standing problem in which we didn't correctly
free resources upon module removal, resulting in a memory leak.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Each multicast group (MID) stores a bitmap of ports to which a packet
should be forwarded to in case an MDB entry associated with the MID is
hit.
Since the initial introduction of IGMP snooping in commit 3a49b4fde2
("mlxsw: Adding layer 2 multicast support") the driver didn't correctly
free these multicast groups upon ungraceful situations such as the
removal of the upper bridge device or module removal.
The correct way to fix this is to associate each MID with the bridge
ports member in it and then drop the reference in case the bridge port
is destroyed, but this will result in a lot more code and will be fixed
in net-next.
For now, upon module removal, traverse the MID list and release each
one.

Some operations in the bridge driver such as MDB deletion are preformed
in an atomic context and thus deferred to a process context by the
switchdev infrastructure.
Therefore, by the time the operation is performed by the underlying
device driver it's possible the bridge port context is already gone.
This is especially true for removal flows, but theoretically can also be
invoked during addition.
Remove the warnings in such situations and return normally.

Mikael Pettersson reported that some test programs in the strace-4.18
testsuite cause an OOPS.
After some debugging it turns out that garbage values are returned
when an exception occurs, causing the fixup memset() to be run with
bogus arguments.
The problem is that two of the exception handler stubs write the
successfully copied length into the wrong register.

On the first revision of the bindings, only the gates + resets were known
in the AO Clock HW, but more registers used to configures AO clock are known
to be spread among the AO register space.
This patch adds a parent node for the entire system control zone for the AO
domain then moves the clock controller as a subnode of the system control
node.

Input source 0 of the mmc controllers is not directly xtal, as currently
described in DT. Each controller is fed by a composite clock (the usual
mux, divider and gate). The muxes inputs are the xtal (default) and the
fclk_div clocks. These parents, along with the divider, should be able to
provide the necessary rates for mmc and nand operation.
The input muxes should also be able to take mpll2, mpll3 and gp0_pll but
these are precious clocks, needed for other usage. It is better if the
mmc does not use these them. For this reason, mpll2, mpll3 and gp0_pll is
not listed among the possible parents.

The clock controller also includes some reset lines. This patch
implements a reset controller to assert and de-assert these resets.
The reset controller itself is registered early (through
CLK_OF_DECLARE_DRIVER) because it is needed very early in the boot
process (to start the secondary CPU cores).
According to the public S805 datasheet there are two more reset bits
in the HHI_SYS_CPU_CLK_CNTL0 register, which are not implemented by
this patch (as these seem to be unused in Amlogic's vendor Linux kernel
sources and their u-boot tree):
- bit 15: GEN_DIV_SOFT_RESET
- bit 14: SOFT_RESET
All information was taken from the public S805 Datasheet and Amlogic's
vendor GPL kernel sources. This patch is based on an earlier version
submitted by Carlo Caione.

User-defined element set registers own handler to get callbacks from TLV
ioctl handler. In the handler, execution path bifurcates depending on
requests from user space. At write request, container in given buffer is
registered to the element set, or replaced old TLV data. At the read
request, the registered data is copied to user space. The command request
is not allowed. In current implementation, function of the handler
includes codes for the two cases.
This commit adds two helper functions for these cases so that readers can
easily get the above design.

In a design of ALSA control core, execution path bifurcates depending on
target element. When a set with the target element has a handler, it's
called. Else, registered buffer is copied to user space. These two
operations are apparently different. In current implementation, they're
on the same function with a condition statement. This makes it a bit hard
to understand conditions of each case.
This commit splits codes for these two cases.

At a previous commit, concurrent requests for TLV data are maintained
exclusively between read requests and write/command requests. TLV
callback handlers in each driver has no risk from concurrent access for
reference/change.
In current implementation, 'struct snd_card' has a mutex to control
concurrent accesses to user-defined element sets. This commit obsoletes it.

In ALSA control interface, applications can execute three types of request
for Type-Length-Value (TLV) data to a set of elements; read, write and
command. In ALSA control core, all of the requests are handled within read
lock to a counting semaphore, therefore several processes can run to access
to the data at the same time for any purposes. This has an issue because
write and command requests have side effect to change state of a set of
elements for the TLV data. Concurrent access should be controlled for each
of reference/change case.
This commit uses the counting semaphore as read lock for TLV read requests,
while use it as write lock for TLV write/command requests. The state of a
set of elements for the TLV data is maintained exclusively between read
requests and write/command requests, or between write and command requests.

Any control event is queued by a call of snd_ctl_notify(). This function
adds the event to each queue of opened file data corresponding to ALSA
control character devices. This function acquired two types of lock; a
counting semaphore for a list of the opened file data and a spinlock for
card data opened by the file. Typically, this function is called after
acquiring a counting semaphore for a list of elements in the card data.
In current implementation of TLV request handler, the function is called
after releasing the semaphore for a list of elements in the card data.
This release is not necessarily needed.
This commit removes the release to call the function within the critical
section so that later commits are simple.
