svn commit: r238257 - in head/sys/ia64: ia64 include

[Marcel Moolenaar]

Author: marcel
Date: Sun Jul  8 18:00:22 2012
New Revision: 238257
URL: http://svn.freebsd.org/changeset/base/238257

Log:
  Move PCPU initialization to a new function called cpu_pcpu_setup().
  This makes it easier to add additional CPU or platform information
  to the per-CPU structure without duplicated code.
