jamal 72032fdbcd xfrm: Introduce LINUX_MIB_XFRMFWDHDRERROR
XFRMINHDRERROR counter is ambigous when validating forwarding
path. It makes it tricky to debug when you have both in and fwd
validation.

Tejun Heo 7d720c3e4f percpu: add __percpu sparse annotations to net
Add __percpu sparse annotations to net.

These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors.  This patch doesn't affect normal builds.

The macro and type tricks around snmp stats make things a bit
interesting.  DEFINE/DECLARE_SNMP_STAT() macros mark the target field
as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.  All
snmp_mib_*() users which used to cast the argument to (void **) are
updated to cast it to (void __percpu **).

Masahide NAKAMURA 9472c9ef64 [XFRM]: Fix statistics.
o Outbound sequence number overflow error status
  is counted as XfrmOutStateSeqError.
o Additionaly, it changes inbound sequence number replay
  error name from XfrmInSeqOutOfWindow to XfrmInStateSeqError
  to apply name scheme above.
o Inbound IPv4 UDP encapsuling type mismatch error is wrongly
  mapped to XfrmInStateInvalid then this patch fiex the error
  to XfrmInStateMismatch.
