Branches:

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

Children:

Parents:

Message:

Introduce PF_ACCESS_UNKNOWN to be used by the debuging/panicking code in
situations in which the trap handler does not know the exact access type.

Do not pass context-specific messages of only minimal information value to
panic_memtrap().
