- * gcc 3.3 and older have trouble determining that PTRS_PER_PGD and PGD_ORDER

  * Align swapper_pg_dir in to 64K, allows its address to be loaded
  * with a single LUI instruction in the TLB handlers.  If we used
  * __aligned(64K), its size would get rounded up to the alignment
  * size, and waste space.  So we place it in its own section and align
  * it in the linker script.
