From: Puranjay Mohan <puranjay@xxxxxxxxxx> Pull-849[1] added the support of '&', '|', and '^' to the herd7 tool's atomics operations. Use these in linux-kernel.def to implement atomic_and()/or()/xor() with all their ordering variants. atomic_add_negative() is already available so add its acquire, release, and relaxed ordering variants.
