[PATCH 02/25] cobalt/kevents: dovetail: drop call to obsolete force_commit_memory()

[Jan Kiszka]

From: Philippe Gerum <rpm at xenomai.org>

A process is now marked for COW-breaking on fork() upon the first call
to dovetail_init_altsched(), and must ensure its memory is locked via
a call to mlockall(MCL_CURRENT|MCL_FUTURE) as usual.

As a result, force_commit_memory() became pointless and was removed
from the Dovetail interface.
