Merge branch 'snmp-stats-update'

Eric Dumazet says:

====================
net: snmp: update SNMP methods

In the old days (before linux-3.0), SNMP counters were duplicated,
one set for user context, and anther one for BH context.

After commit 8f0ea0fe ("snmp: reduce percpu needs by 50%")
we have a single copy, and what really matters is preemption being
enabled or disabled, since we use this_cpu_inc() or __this_cpu_inc()
respectively.

This patch series kills the obsolete STATS_USER() helpers,
and rename all XXX_BH() helpers to __XXX() ones, to more
closely match conventions used to update per cpu variables.

This is probably going to hurt maintainers job for a while,
since cherry-picks will not be clean, but this had to be
cleaned at one point. I am so sorry guys.
