[Qemu-devel] [PATCH v1 10/22] RISC-V: Hold rcu_read_lock when accessing memory

>From reading other code that accesses memory regions directly, it appears that the rcu_read_lock needs to be held. Note: the original code for accessing RAM directly was added because there is no other way to use atomic_cmpxchg easily. Signed-off-by: Michael Clark Signed-off-by: Stefan O'Rear S
