Author: jhb Date: Wed Apr 13 17:37:31 2016 New Revision: 297931 URL: https://svnweb.freebsd.org/changeset/base/297931 Log: Expose doreti as a global symbol on amd64 and i386. doreti provides the common code path for returning from interrupt andlers on x86. Exposing doreti as a global symbol allows kernel modules to include low-level interrupt handlers instead of requiring all low-level handlers to be statically compiled into the kernel.
