[PATCH] Fix kunmap_atomic's use of kpte_clear_flush()
kunmap_atomic() will call kpte_clear_flush with vaddr/ptep arguments which
don't correspond if the vaddr is just a normal lowmem address (ie, not in
the KMAP area). This patch makes sure that the pte is only cleared if kmap
area was actually used for the mapping.
