Timestamp:

Author:

Branches:

lfn, master, serial, ticket/834-toolchain-update, topic/msim-upgrade, topic/simplify-dev-export

Children:

Parents:

Message:

Introduce macros CPU, THREAD, TASK and use them to replace the→cpu, the→thread, the→task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
