Seems that commit 210b1607012cc9034841a393e0591b2c86d9e26c
(KVM: s390: Removed SIE_INTERCEPT_UCONTROL) lost a hunk when we
reworked our patch queue to rework the async_fp code. We now
ignore faults on the sie instruction (guest accesses non-existing
memory) instead of sending a fault into the guest. This leads to
hang situations with the old virtio transport that checks for
descriptor memory after guest memory. Instead of bailing out this
code now goes wild...
Lets re-add the check.

For user space packet capturing libraries such as libpcap, there's
currently only one way to check which BPF extensions are supported
by the kernel, that is, commit aa1113d9f85d ("net: filter: return
-EINVAL if BPF_S_ANC* operation is not supported"). For querying all
extensions at once this might be rather inconvenient.
Therefore, this patch introduces a new option which can be used as
an argument for getsockopt(), and allows one to obtain information
about which BPF extensions are supported by the current kernel.
As David Miller suggests, we do not need to define any bits right
now and status quo can just return 0 in order to state that this
versions supports SKF_AD_PROTOCOL up to SKF_AD_PAY_OFFSET. Later
additions to BPF extensions need to add their bits to the
bpf_tell_extensions() function, as documented in the comment.

Pull networking fixes from David Miller:
1) The value choosen for the new SO_MAX_PACING_RATE socket option on
parisc was very poorly choosen, let's fix it while we still can.
From Eric Dumazet.
2) Our generic reciprocal divide was found to handle some edge cases
incorrectly, part of this is encoded into the BPF as deep as the JIT
engines themselves. Just use a real divide throughout for now.
From Eric Dumazet.
3) Because the initial lookup is lockless, the TCP metrics engine can
end up creating two entries for the same lookup key. Fix this by
doing a second lookup under the lock before we actually create the
new entry. From Christoph Paasch.
4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork.
5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting.
From Dan Carpenter.
6) Netlink socket dumping uses the wrong socket state for timewait
sockets. Fix from Neal Cardwell.
7) Fix netlink memory leak in ieee802154_add_iface(), from Christian
Engelmayer.
8) Multicast forwarding in ipv4 can overflow the per-rule reference
counts, causing all multicast traffic to cease. Fix from Hannes

The s390 bpf jit compiler emits the signed divide instructions "dr" and "d"
for unsigned divisions.
This can cause problems: the dividend will be zero extended to a 64 bit value
and the divisor is the 32 bit signed value as specified A or X accumulator,
even though A and X are supposed to be treated as unsigned values.
The divide instrunctions will generate an exception if the result cannot be
expressed with a 32 bit signed value.
This is the case if e.g. the dividend is 0xffffffff and the divisor either 1
or also 0xffffffff (signed: -1).
To avoid all these issues simply use unsigned divide instructions.

DT clocks are mostly missing clkdm info now, and this causes an issue with
counter32k which makes its slave idlemode wrong and prevents core idle.
Fixed by initializing the hwmod clkdm pointers for omap3 also which makes
sure the clkdm flag matching logic works properly.
This patch also changes the return value for _init_clkdm to 0 for
incorrect clkdm_name, as this a warning, not a fatal error.
