Attilio Rao 786ef92b7b Bump MAXCPU for amd64, ia64 and XLP mips appropriately.
From now on, default values for FreeBSD will be 64 maxiumum supported
CPUs on amd64 and ia64 and 128 for XLP. All the other architectures
seem already capped appropriately (with the exception of sparc64 which
needs further support on jalapeno flavour).

Bump __FreeBSD_version in order to reflect KBI/KPI brekage introduced
during the infrastructure cleanup for supporting MAXCPU > 32. This
covers cpumask_t retiral too.

The switch is considered completed at the present time, so for whatever
bug you may experience that is reconducible to that area, please report
immediately.
