NAME
       vm_unmap_aliases - unmap outstanding lazy aliases in the vmap layer

SYNOPSIS
       void vm_unmap_aliases(void);

ARGUMENTS
       void
	   no arguments

DESCRIPTION
       The vmap/vmalloc layer lazily flushes kernel virtual mappings primarily
       to amortize TLB flushing overheads. What this means is that any page
       you have now, may, in a former life, have been mapped into kernel
       virtual address by the vmap layer and so there might be some CPUs with
       TLB entries still referencing that page (additional to the regular 1:1
       kernel mapping).

       vm_unmap_aliases flushes all such lazy mappings. After it returns, we
       can be sure that none of the pages we have control over will have any
       aliases from the vmap layer.
