    Subjectremap 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().
