Doug Moore d9b8e5a748 powerpc pmap: initialize kernel pmap radix trie ... Commit 2d2bcba7ba changed radix trie implementation and made it necessary that radix tries be initialized with vm_radix_init. @dbaio reports that in some configurations, there is a powerpc boot panic and that this commit introduced the problem. In powerpc/aim/mmu_radix.c, the radix trie in kernel_pmap is initialized by zeroing all its fields. Add a call to vm_radix_init to properly initialize kernel_pmap->pm_radix.
