New Revision: 224221
URL: http://svn.freebsd.org/changeset/base/224221
Log:
Remove explicit MAXCPU usage from sys/pcpu.h avoiding a namespace
pollution. That is a step further in the direction of building correct
policies for userland and modules on how to deal with the number of
maxcpus at runtime.
