Subject: remap allocator for per-CPU memory

Didn't the addition of this allocator introduce another case that needs special
treatment in pageattr.c? Since large pages are used for mapping the allocated
memory, but only part of the initially allocated large pages are actually
retained, there's now the potential for TLB aliases with different cache
attributes for those parts of these pages that get passed back through
free_bootmem().
