Subject: Rename the cpu_dep hook ``steal_pages'' to ``init'', as it serves as an
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=53239e3c629a96e23e80f904c132774826ff4ea0;p=openbsd

Rename the cpu_dep hook ``steal_pages'' to ``init'', as it serves as an
early initialization routine (to enable caches, etc) while still running
physical, and does not allocate memory anymore.

(The irony in this is that forthcoming KA60 support actually steals pages
 in its init function...)
