Changeset 4c4b53c in mainline

Message:

Rename __entry to the usual _start.

Except for MIPS, where the default is __start.
This is to avoid customizations in the toolchain as much as possible.
With this change, most platforms need no customization to linker behavior
at all, thus reducing maintainance concerns.
