[Lse-tech] lockmeter on ia64

[Ray B. <ra...@sg...>]

Andrew,

It looks like the 2.6.0 lockmeter patch has lost the configuration menu entry to
enable lockmeter on ia64.  This is true of both 2.6.0-test10-mm1 and
2.6.0-test11-mjb3.  (Martin appears to pull this from your tree.)  Below is
the trivial patch to fix this.  With this change it appears to work fine on
Altix, at least.
