Alexei Starovoitov says: ==================== BPF testsuite and cleanup This patchset adds BPF testsuite and improves readability of classic to internal BPF converter. The testsuite helped to find 'negative offset bug' in x64 JIT that was fixed by commit fdfaf64e ("x86: bpf_jit: support negative offsets") It can be very useful for classic and internal JIT compiler developers. Also it serves as performance benchmark. x86_64/i386 pass all tests with and without JIT. arm32 JIT is failing negative offset tests which are unsupported. Internal BPF tests are much larger than classic tests to cover different combinations of registers. Negative tests check correctness of classic BPF verifier which must reject them. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The testsuite covers classic and internal BPF instructions. It is particularly useful for JIT compiler developers. Adds to "net" selftest target. The testsuite can be used as a set of micro-benchmarks. It measures execution time of each BPF program in nsec. This patch adds core framework.

This revert commit efb842c45("sctp: optimize the sctp_sysctl_net_register"), Since it doesn't kmemdup a sysctl_table for init_net, so the init_net->sctp.sysctl_header->ctl_table_arg points to sctp_net_table which is a static array pointer.

2014-05-07net: clean up snmp stats codeWANG Cong
commit 8f0ea0fe3a036a47767f9c80e (snmp: reduce percpu needs by 50%) reduced snmp array size to 1, so technically it doesn't have to be an array any more. What's more, after the following commit: commit 933393f58fef9963eac61db8093689544e29a600 Date: Thu Dec 22 11:58:51 2011 -0600 percpu: Remove irqsafe_cpu_xxx variants We simply say that regular this_cpu use must be safe regardless of preemption and interrupt state. That has no material change for x86 and s390 implementations of this_cpu operations. However, arches that do not provide their own implementation for this_cpu operations will now get code generated that disables interrupts instead of preemption. probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after almost 3 years, no one complains. So, just convert the array to a single pointer and remove snmp_mib_init() and snmp_mib_free() as well.

2014-05-07isdn: hisax: remove some dead codeDan Carpenter
The HISAX_HFC4S8S_PCIMEM code hasn't been able to compile since before the start of git history. I have deleted it. There are also a few indenting mistakes where one side of the ifdef wasn't indented correctly which I fixed as well.
