Merge branch 'dev_base_lock-remove'
Eric Dumazet says:
====================
net: complete dev_base_lock removal
Back in 2009 we started an effort to get rid of dev_base_lock
in favor of RCU.
It is time to finish this work.
Say goodbye to dev_base_lock !
v4: rebase, and move dev_addr_sem to net/core/dev.h in patch 06/13 (Jakub)
v3: I misread kbot reports, the issue was with dev->operstate (patch 10/13)
So dev->reg_state is back to u8, and dev->operstate becomes an u32.
Sorry for the noise.
v2: dev->reg_state must be a standard enum, some arches
do not support cmpxchg() on u8.
