mptcp_push_pending() is called even on orphaned

data at close() time.
To cope with the above MPTCP needs to handle explicitly

- do not mark memory as protected too early
Packets are processed even though the first fragment don't include all
headers through the upper layer header. This breaks TAHI IPv6 Core
Conformance Test v6LC.1.3.6.
Referring to RFC8200 SECTION 4.5: "If the first fragment does not include
all headers through an Upper-Layer header, then that fragment should be
discarded and an ICMP Parameter Problem, Code 3, message should be sent to
the source of the fragment, with the Pointer field set to zero."
The fragment needs to be validated the same way it is done in
commit 2efdaaaf88 ("IPv6: reply ICMP error if the first fragment don't
include all headers") for ipv6. Wrap the validation into a common function,
ipv6_frag_thdr_truncated() to check for truncation in the upper layer
header. This validation does not fullfill all aspects of RFC 8200,
section 4.5, but is at the moment sufficient to pass mentioned TAHI test.
In netfilter, utilize the fragment offset returned by find_prev_fhdr() to
let ipv6_frag_thdr_truncated() start it's traverse from the fragment
header.
Return 0 to drop the fragment in the netfilter. This is the same behaviour
as used on other protocol errors in this function, e.g. when
nf_ct_frag6_queue() returns -EPROTO. The Fragment will later be picked up
by ipv6_frag_rcv() in reassembly.c. ipv6_frag_rcv() will then send an
appropriate ICMP Parameter Problem message back to the source.

KVM does not have separate ASIDs for L1 and L2; either the nested
hypervisor and nested guests share a single ASID, or on older processor
the ASID is used only to implement TLB flushing.
Either way, ASIDs are handled at the VM level. In preparation
for having different VMCBs passed to VMLOAD/VMRUN/VMSAVE for L1 and
L2, store the current ASID to struct vcpu_svm and only move it to
the VMCB in svm_vcpu_run. This way, TLB flushes can be applied
no matter which VMCB will be active during the next svm_vcpu_run.

Fix usage counter leak by adding a general sync ops
In many case, we need to check return value of pm_runtime_get_sync,
but it brings a trouble to the usage counter processing. Many callers
forget to decrease the usage counter when it failed, which could
resulted in reference leak. It has been discussed a lot[0][1]. So we

pm_runtime_get_sync() will increment pm usage at first and it will
resume the device later. If runtime of the device has error or
device is in inaccessible state(or other error state), resume
operation will fail. If we do not call put operation to decrease
the reference, it will result in reference count leak. Moreover,
this device cannot enter the idle state and always stay busy or other
non-idle state later. So we fixed it by replacing it with
pm_runtime_resume_and_get.
