Thanks, I'm fine with merging these patches, but a quick check tells me
that at least the first one caused some issues that were later fixed,
for example :

Subject: [PATCH] ipv6: some ipv6 statistic counters failed to disable bh
After commit c15b1ccadb323ea ("ipv6: move DAD and addrconf_verify
processing to workqueue") some counters are now updated in process context
and thus need to disable bh before doing so, otherwise deadlocks can
happen on 32-bit archs. Fabio Estevam noticed this while while mounting
a NFS volume on an ARM board.
Can you please have a quick check to ensure that all necessary fixes
that come with these two patches are also identified ? I'll then queue
them all at once.
Thanks!
Willy
