Cover letter [PATCH tip/core/rcu 0/9] Stop using ACCESS_ONCE (for v4.2)

Hello!

This patch series converts from ACCESS_ONCE() to either READ_ONCE() or WRITE_ONCE(), as appropriate. This permits better code generation and error checking, and is also more compatible with C11 directions. Each file is updated separately to simplify handling of git conflicts.

Thanx, Paul
