Subject: [PATCH -tip 00/12] locking/atomics: Add and use inc,dec calls for FETCH-OP flavors

Hi,

The series is really straightforward and based on Peter's work that
introduces[1] the atomic_fetch_$op machinery. Only patch 1 implements
the actual atomic_fetch_{inc,dec} calls based on atomic_fetch_{add,sub}.

The rest of the patches really update callers that are doing the ugly
<op> - N workaround to compute the previous state before the variable's
modification.

Applies on today's -tip.

Thanks!
